We report a case of unilateral serous choroidal effusion in a patient without prior glaucoma surgeries that developed within 1 week of starting topical dorzolamide. A Caucasian female in her 60s with a history of severe primary open-angle glaucoma in the left eye without prior glaucoma surgeries developed irritation and subsequently blurry vision in her left eye within 1 week of starting topical dorzolamide 2% in the left eye only. Funduscopic exam and B-scan ultrasound demonstrated a serous choroidal effusion in the nasal and temporal periphery. After discontinuing dorzolamide and initiating prednisolone and cycloplegic agents, the choroidal effusions fully resolved after 2 weeks, and vision returned to baseline. Choroidal effusion can occur as a result of an idiosyncratic reaction to topical dorzolamide even in patients without prior glaucoma surgeries. Immediate cessation of dorzolamide and treatment with steroid and cycloplegic agents result in good vision recovery for dorzolamide-induced choroidal effusion., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Purpose: microRNA-328 has been reported as a risk factor for myopia development. SHJ002 is an antisense for microRNA-328, and SHJ002 was formulated as ophthalmic solution for a novel microRNA therapy. We aimed to investigate the safety and tolerability of SHJ002 ophthalmic solution in children., Methods: This was a single-center, open-label, first-in-human trial in healthy children (NCT04928144). All subjects received the study medication. The trial had 2 stages. Stage 1 was an intrasubject dose-escalation study, and stage 2 was the highest tolerable dose study. The SHJ002 ophthalmic solution was instilled in a randomly selected study eye in each participant, whereas the other untreated eye served as a negative control. Three participants were assigned to stage 1, and they received eye drops of 3 concentrations (0.025%, 0.08%, and 0.25%), each of which was used for 3 consecutive days. The highest tolerable dose from stage 1 was used in stage 2 where another 9 participants were recruited for 28-day treatment. Ocular assessments, physical examination, and vital signs were measured to evaluate safety and tolerability., Findings: There were 4 boys and 8 girls with a mean age of 12.3 years and a SD of 1.56. All participants were Asians. All 3 concentrations used in stage 1 were well tolerated, and the dose of 0.25% was used in stage 2. There were no reports of discomfort. There was only 1 mild adverse event (punctate keratitis) in the untreated eye in 1 participant, which was deemed as "unrelated to study drug.", Implications: SHJ002 is a novel microRNA therapy that uses eye drop instillation. SHJ002 ophthalmic solution is generally safe and tolerable, which warrants further investigations in Phase II and III trials., Clinicaltrials: gov identifier: NCT04928144., Competing Interests: Declaration of competing interest C.-L.

Objective: This study aims to identify safety signals of ophthalmic prostaglandin analogues through data mining the Food and Drug Administration Adverse Event Reporting System (FAERS) database., Methods: A data mining search by proportional reporting ratio, reporting OR, Bayesian confidence propagation neural network, information component 0.25 and χ 2 for safety signals detection was conducted to the FAERS database for the following ophthalmic medications: latanoprost, travoprost, tafluprost and bimatoprost., Results: 12 preferred terms were statistically associated: diabetes mellitus, n=2; hypoacusis, n=2; malignant mediastinal neoplasm, n=1; blood immunoglobulin E increased, n=1; cataract, n=1; blepharospasm, n=1; full blood count abnormal, n=1; skin exfoliation, n=1; chest discomfort, n=1; and dry mouth, n=1., Limitation of the Study: The FAERS database's limitations, such as the undetermined causality of cases, under-reporting and the lack of restriction to only health professionals reporting this type of event, could modify the statistical outcomes. These limitations are particularly relevant in the context of ophthalmic drug analysis, as they can affect the accuracy and reliability of the data, potentially leading to biased or incomplete results., Conclusions: Our findings have revealed a potential relationship due to the biological plausibility among malignant mediastinal neoplasm, full blood count abnormal, blood immunoglobulin E increased, diabetes mellitus, blepharospasm, cataracts, chest discomfort and dry mouth; therefore, it is relevant to continue investigating the possible drug-event association, whether to refute the safety signal or identify a new risk., Competing Interests: Competing interests: Laboratorios Sophia provided support in the form of salaries for authors (HC-S, MSR-L, OOM, LYR-H), but did not have any additional role., (© Author(s) (or their employer(s)) 2024.

Background: The prevalence of contact allergy to various ophthalmic medications appears to be rare; however, data on culprits, clinical relevance of sensitizations, and changes in frequency within recent decades are limited., Objective: This study aimed to investigate the clinical relevance, risk factors, and prevalence of contact allergy to topical ophthalmic medications in patients suspected of allergic contact dermatitis to ophthalmic medication., Methods: We retrospectively analysed patch test results and clinical data for 754 patients patch-tested with an ophthalmic medication series at our tertiary referral centre between January 1992 and December 2022., Results: In total, 37.5% (283/754) of patch-tested patients had a contact allergy to at least one ophthalmic allergen, with 87.3% (247) being clinically relevant sensitization. Phenylephrine (31.8%, 192/604), povidone-iodine (29%, 27/93), and tobramycin (23%, 46/200) were the most important sensitizers. The incidence of contact allergies increased significantly in a linear manner (p = 0.008) from 20% to 44.1% within the study period. Male sex and age above 40 were risk factors for contact allergy to ophthalmic medication., Conclusions: One third of patch tested patients had allergic contact dermatitis to ophthalmic medication, particularly phenylephrine. Male sex and age above 40 years were independent risk factors and drove the linear increase in contact allergy to ophthalmic medications within the past 31 years., (© 2024 The Authors.

Background: Unpreserved single-dose unit (SDU) eye drops are commonly used to avoid benzalkonium chloride-related toxicity. Although intended for single use, many patients report off-label repeated use of SDUs over a prolonged period. We investigated whether repeated use of dexamethasone 0.1% SDUs in the same patient increases the bacterial contamination rate., Methods: We prospectively enrolled patients scheduled for inpatient corneal and glaucoma surgery receiving dexamethasone 0.1% SDU four times per day from the same vial. To assess contamination rates, one drop from the vial was cultured immediately after opening the SDU (t0), 10 hours later after four drop applications (t10) and 24 hours after opening without further drop applications (t24). Conjunctival swabs were taken before and after drop application. Contamination rate was assessed with a standard clinical culturing protocol without introducing a positive control., Results: 110 eyes of 109 patients were evaluated. Drops collected immediately after opening the SDU (t0) were contaminated in 9/110 cultures (8.1%). At t10, 13/110 cultures were contaminated (11.8%; p=0.267) and 11/110 at t24 (10.0%; t24 vs t0; p=1.00). In 5 of 21 cases of contaminated drops at t10 and/or t24, the same isolates were cultured from the initial conjunctival swab and the SDU. In three cases, the same bacterial species was found in consecutive samples., Conclusion: The contamination rate of the SDU did not increase after multiple use within 24 hours. Contamination from fingertip flora was more likely than from ocular surface flora. Reuse of dexamethasone 0.1% SDU in the same patient within 24 hours appears to be safe., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Povidone, a synthetic polymer commonly used in various products such as antiseptics, cosmetics, and medications, has been associated with allergic reactions, including anaphylaxis. Despite its widespread use, cases of povidone-induced anaphylaxis, especially in children, are under-recognized. This case report aims to highlight the importance of considering povidone allergy in pediatric patients presenting with anaphylaxis. Case Presentation: We describe a 3-year-old boy who experienced anaphylaxis following the application of povidone-iodine antiseptic solution to a leg wound. He presented with generalized urticaria, angioedema, dyspnea, and cough. Prompt diagnosis and management were initiated in the emergency department. He experienced the second anaphylaxis with povidone-containing eye drops prescribed during an ophthalmology visit. Conclusions: Povidone allergy should be considered in pediatric patients presenting with anaphylaxis, especially those with idiopathic reactions or multiple drug allergies. Clinicians should emphasize patient education on label reading and the provision of adrenaline autoinjectors to prevent life-threatening reactions associated with povidone exposure.

Allergic contact dermatitis induced by the use of ophthalmic topical drugs is one of the most common causes of eyelid dermatitis. The introduction of new formulations, both of active ingredients and excipients, and the lack of marketing in some of them, makes patch testing in patients whose source of contact are topical ophthalmic drugs truly challenging. Across this manuscript, most, if not all, topical ophthalmic drugs used in our national health system have been collected, including information on the allergens available, and the concentration and vehicle advised for those that still remain unavailable., (Copyright © 2024 AEDV.

Purpose: The safety and efficacy of a novel topical ocular anesthetic (AG-920 sterile ophthalmic solution, 8%) was previously evaluated in adults. For both clinical and regulatory purposes, this new agent was evaluated in children. Methods: This was a Phase 3, randomized, active-controlled, single-masked, parallel-group design study in healthy pediatric subjects performed at a private practice retina clinic in the United States. The safety and anesthetic efficacy of AG-920 was compared with proparacaine hydrochloride ophthalmic solution 0.5% in 60 children undergoing ophthalmic examinations. The primary efficacy endpoint was whether the investigator was able to perform the eye examination. Results: In all subjects in each treatment group, the investigator was able to perform the eye examination without additional local anesthetic. There were no adverse events reported in this study. In both the study eye and fellow eye, there were no notable changes after dosing, and both treatment groups were similar. All external eye exams in all subjects in both treatment groups were normal. Conclusions: In this pediatric population aged 7 months to >11 years, AG-920 was therapeutically equivalent to marketed proparacaine with respect to having an ophthalmic examination performed without needing additional local anesthetic. Further, AG-920 was well tolerated, and there were no clinically significant safety findings.

Aim: To prove non-inferiority of preservative-free (PF) latanoprost versus benzalkonium chloride (BAK) containing latanoprost in lowering intraocular pressure (IOP) in primary open-angle glaucoma (POAG) or ocular hypertension (OHT) patients., Design and Methods: This phase III, randomized, investigator-masked trial primarily aimed to demonstrate non-inferiority of YSLT PF latanoprost 50 μg/ml (Yonsung GmbH) to latanoprost (Xalatan®) 50 μg/ml (Pfizer) in reducing IOP from Baseline to Week 12. Secondary aims included conjunctival hyperemia evaluation and difference in ocular comfort levels. Total 130 patients with POAG or OHT were enrolled and randomized (1:1 ratio) to receive YSLT or latanoprost, instilling eye drops daily for 12 weeks., Results: At Week 12, mean diurnal IOP reduction was -7.67 ± 2.104 mmHg for YSLT PF latanoprost and -7.77 ± 2.500 for latanoprost. The 97.5% confidence interval of between-treatment group difference in IOP reduction from Baseline to Week 12 was [-0.846, +∞), not crossing the non-inferiority margin of -1.5 mmHg. A low incidence of mild topical treatment emergent adverse events (TEAEs) was observed in both groups, while no serious TEAEs were reported., Conclusions: YSLT eye drops demonstrated non-inferiority to latanoprost in reducing IOP. Both products were well tolerated without serious TEAEs reported.

Sialorrhea or drooling is a common problem in children and adults with neurodevelopmental disorders. It can negatively impact the quality of life due to its physical and psychological manifestations. Providers commonly prescribe atropine eye drops for topical administration to the oral mucosa, as an off-label treatment to manage sialorrhea. However, the off-label use of atropine eye drops can be associated with medication and dosing errors and systemic side effects. To address these limitations of treatment, we developed a mucoadhesive topical oral gel formulation of atropine as an alternative route to off-label administration of atropine eye drops. In this clinical pharmacokinetic (PK) study, we evaluated the safety and PK of atropine gel (0.01% w/w) formulation after single-dose administration to the oral mucosa in 10 healthy volunteers. The PK data showed that after topical administration to the oral mucosa, atropine followed a two-compartment PK profile. The maximum plasma concentration and area under the curve extrapolated to infinite time were 0.14 ng/mL and 0.74 h·ng·mL -1 , respectively. The absorption rate constant calculated by the compartmental analysis was 0.4 h -1 . Safety parameters, such as heart rate, blood pressure, and oxygen saturation, did not significantly change before and after administration of the gel formulation, and no adverse events were observed in all participants who received atropine gel. These data indicate that atropine gel formulation has a satisfactory PK profile, is well-tolerated at the dose studied, and can be further considered for clinical development as a drug product to treat sialorrhea., (© 2024 The Authors.

Background: Anaphylaxis is a severe systemic allergic reaction that can be life-threatening, timely diagnosis and treatment is required in these patients, one of the most frequent triggers is pharmacological., Objective: To report the case of a patient who presented anaphylaxis due to eye drops., Case Report: A 7-year-old male with a history of rhinitis and asthma with good control. It started with itchy eyes, ophthalmic drops were administered, composition: Polyethylene glycol 400, 0.4%, Propylene glycol 3 mg, polyquad 0.001%, presenting at 15 minutes an episode of anaphylaxis initially characterized by pruritus and intense conjunctival erythema, later nausea, vomiting, sweating, weakness, urticaria/facial angioedema and dyspnea were added, this episode was controlled opportunely with Levocetirizine 5 mg sublingual and Betametasona 4 mg intramuscular, progressively improving over the next 2 hours. The patient was evaluated by the Allergist, written recommendations were given to the mother in case this reaction occurred again, the use of the drops was prohibited, and the performance of skin test and a probable conjunctival provocation protocolized with the ophthalmic drops were pending. Accidentally 2 months later the patient was re-exposed with the same eye drops, presenting a similar reaction 15 minutes after the administration of the medication, they went to the emergency room where he received antihistamine and corticosteroid intravenous treatment, after this re-exposure is confirmed to the ophthalmic drops mentioned above as a trigger of anaphylaxis in this patient., Conclusions: We present a case of conjunctival anaphylaxis after application of eye drops, confirmed by re-exposure to the drug. It is essential to give diagnoses, recommendations with treatments and avoidance of the probable triggering agent of the reaction. The administration of immediate medication when the allergic episode begins in these patients can be vital, even more so when they live far from a health center, as was the case in this patient.

Purpose: This study was undertaken to evaluate the safety and efficacy of CSF-1 (0.4% pilocarpine hydrochloride ophthalmic solution) for use in individuals with presbyopia., Methods: Two Phase 3 multicenter, randomized, double-masked, vehicle-controlled, parallel-group clinical trials were conducted in 35 private ophthalmology clinics in the United States from October 2020 to February 2022. Key inclusion criteria were the following: (1) age 45-64 years, (2) distance-corrected near visual acuity (DCNVA) at 40 cm ≥0.40 and ≤0.90 logarithm of the minimum angle of resolution (logMAR, approximately 20/50-20/160 Snellen) in at least 1 eye, (3) manifest refraction (MR) between -4.50 and +2.00 diopter (D) sphere in each eye with ≤2.00D difference between eyes, (4) <2.00D of cylinder MR in each eye, (5) ≤0.04 logMAR (20/20-2 or better) corrected distance visual acuity (CDVA) at 4 m in each eye. Key exclusion criteria were the following: (1) >0.14 logMAR (7 letters) improvement in post-vehicle treatment in monocular DCNVA in either eye at visit 1, (2) introcular pressure (IOP) <9 or >22 mm Hg, (3) average dark-adapted pupillometry <3.5 mm in either eye, (4) prior refractive surgery or intraocular lens (IOL) implantation. Participants applied CSF-1 or vehicle twice per day for 2 weeks. Efficacy and safety assessments were performed at several times on days 1, 8, and 15. Response was defined as ≥3-line gain in DCNVA without loss of ≥1-line in CDVA in the study eye under mesopic room lighting conditions. The primary efficacy endpoint was measured 1 hour post-dose 1 on day 8. Key secondary endpoints were 2 hours post-dose 1, and 1 and 2 hours post-dose 2, also on day 8. Safety endpoints were ocular and non-ocular treatment-related adverse events (TRAE), conjunctival redness, drop comfort, slit-lamp biomicroscopy, intraocular pressure, indirect fundoscopy, and CDVA at 4 m., Findings: Six hundred thirteen participants were randomized to CSF-1 (n = 309) or vehicle (n = 304). Participants were predominantly White (80.8%) and female (62.0%), with mean age (standard deviation) of 54.7 (4.8). CSF-1 met the primary and key secondary endpoints. At the primary endpoint, 40.1% of the CSF-1 group achieved response versus 19.1% of the vehicle group (P < 0.0001). The percentage of responders was significantly greater in CSF-1 compared with vehicle at all tested times. Changes from baseline in all safety endpoints were comparable between groups. Most adverse events (AEs) were mild and transient. Neither serious nor severe AEs were reported with CSF-1., Implications: CSF-1, a low-dose pilocarpine ophthalmic solution, demonstrated superiority to vehicle in improving near vision in individuals with presbyopia without compromising distance vision. CSF-1 demonstrated a favorable safety profile., Clinicaltrials: gov identifier: NCT04599933 (NEAR-1), NCT04599972 (NEAR-2)., Competing Interests: Declaration of competing interest Edward Holland is a consultant for Alcon, Aurion Biotech and Orasis.

A large number of studies have evaluated the efficacy of low-dose atropine in preventing or slowing myopic progression. However, it is challenging to evaluate the ocular safety from these studies. We aimed to evaluate the incidence of adverse events induced by atropine in children with myopia. We performed a systematic literature search in several databases for studies published until November 2022. The incidence of adverse events induced by atropine was pooled by a common-effect (fixed-effect) or random-effects model. Subgroup analyses were conducted according to drug doses, types of adverse events, and ethnicity. A total of 31 articles were ultimately included in the study. The overall incidence of adverse events for atropine was 5.9%, and the incidence of severe adverse events was 0.0%. The most commonly reported adverse events were photophobia (9.1%) and blurred near vision (2.9%). Other adverse events including eye irritation/discomfort, allergic reactions, headache, stye/chalazion, glare, and dizziness occurred in less than 1% of the patients. The incidence of atropine-induced adverse events varied depending on the drug doses. A lower dose of atropine was associated with a lower incidence of adverse events. There was no significant difference in the incidence of adverse events for low-dose atropine between Asian and White children. Our study suggests photophobia and blurred near vision are the most frequently reported adverse events induced by atropine. Low-dose atropine is safer than moderate- and high-dose atropine. Our study could provide a safe reference for ophthalmologists to prescribe atropine for myopic children., (© 2023, The American College of Clinical Pharmacology.)

We compared the efficacy and safety of autologous-serum (AS) and platelet-rich plasma (PRP) eye drops for dry eye (DE) treatment in primary Sjögren's syndrome (SS). This prospective, randomized, double-blinded clinical study included patients diagnosed with primary SS DE. Thirty-eight participants were randomly assigned to the AS or PRP groups. Corneal and conjunctival staining scores, Schirmer I test, tear film break-up time (TBUT), and ocular surface disease index (OSDI) scores were evaluated at 4 and 12 weeks. Conjunctival impression cytology (CIC) metaplasia grade and goblet cell density grade at 12 weeks were compared with those at baseline. Corneal and conjunctival staining scores and TBUT significantly improved at 4 and 12 weeks in both groups (all p < 0.005). No significant difference between the AS and PRP groups was observed at 4 and 12 weeks. The Schirmer I values, OSDI scores, CIC metaplasia grade, and goblet cell density grade did not significantly change at 4 and 12 weeks in either group. Both AS and PRP eye drops are effective for primary SS DE without a significant difference. Considering that the preparation time of PRP is shorter than that of AS, PRP can be a good alternative treatment for primary SS DE., (© 2023. The Author(s).)

Eyelid and periorbital dermatitis remains a distressing and recalcitrant disease. Contact dermatitis remains the most common cause of eyelid and periorbital dermatitis. Ophthalmic solutions used in the treatment of ophthalmic conditions can often be the cause. This article is an update of our previous study, summarizing the contact allergens involved and the new test concentrations reported to investigate through patch testing. New insights found during the review are also documented.

Purpose: The melanocortin receptor pan-agonist PL9643, a potential therapy for ocular diseases, was investigated in a phase 2, 12-week study in patients with dry eye disease (DED). Methods: This was a placebo-controlled study evaluating efficacy and safety of thrice-daily PL9643. Placebo (vehicle) was similar to tears. Primary endpoints were intra-patient changes in inferior corneal fluorescein staining and ocular discomfort after 12 weeks. Secondary endpoints were changes in additional DED signs or symptoms. Multiple secondary endpoints were not adjusted for multiplicity. Patients with moderate or severe DED were analyzed in addition to the overall intent-to-treat (ITT) population. Results: In the ITT population ( n  = 160) the PL9643 group did not demonstrate significant treatment difference versus placebo at week 12/day 85 for the primary endpoints ( P  > 0.05). In patients with moderate or severe DED ( n  = 53), PL9643 treatment demonstrated either nominally significant ( P  < 0.05) or trending ( P  < 0.1) improvement over placebo in mean change from baseline at week 12/day 85 in several sign endpoints, including fluorescein staining in inferior, superior, corneal sum, and total sum regions; Lissamine Green staining in temporal, nasal, conjunctival sum, and total sum regions; and tear film breakup time. Conjunctival redness also showed (nonsignificant) improvement at week 12/day 85. There were no drug-related adverse events (AEs) and no drug-related discontinuations. Conclusions: PL9643 showed no significant efficacy for the ITT population; however, efficacy results across several signs and symptoms in the subpopulation of moderate to severe DED patients, the low number of ocular AEs, and no tolerability issues suggest that PL9643 shows promise as a therapeutic for DED. Clinical Trial Registration number: NCT04268069.

Purpose: To evaluate the safety and efficacy of atropine for childhood myopia and further explore the optimal concentration of atropine, so as to provide more reference for clinical application., Methods: PubMed, Embase, Cochrane Library and ClinicalTrials.gov were comprehensively searched for randomized controlled trials (RCTs) up to October 14, 2021. The efficacy outcomes were progression of spherical equivalent (SE) and axial length (AL). The safety outcomes included accommodation amplitude, pupil size and adverse effects. The meta-analysis was performed using Review Manager 5.3., Results: Eighteen RCTs involving 3002 eyes were included. The results showed that at 6-36 months of treatment, atropine was effective in slowing the progression of myopia in children. At 12 months, the WMD of SE and AL of low-dose atropine was 0.25 diopters (D) and 0.1 millimeter (mm), moderate-dose atropine was 0.44 D and 0.16mm, high-dose atropine was 1.21 D and 0.82mm, respectively, compared with the control group. Similarly, at 24 months, low-dose atropine was 0.22 D and 0.14mm, moderate-dose atropine was 0.60 D, high-dose atropine was 0.66 D and 0.24mm, respectively. Interestingly, we also found that there was no significant difference in the effects of low-dose atropine on accommodation amplitude and photopic pupil size compared with the control group, and the rate of photophobia, allergy, blurred vision and other side effects was similar between the low-dose atropine group and the control group. In addition, atropine appears to be more effective in myopic children in China than in other countries., Conclusions: Atropine in various concentrations can effectively slow myopia progression in children, and its effect is dose-dependent, while low-dose atropine (0.01% atropine) appears to be safer., (Copyright © 2023 Elsevier Masson SAS.

A man in his 70s on regular follow-up with an ophthalmologist for 10 years presented with blurry vision in his right eye for 4 days. He was diagnosed with elevated intraocular pressure (IOP) bilaterally 18 months earlier and treated with antiglaucoma eye-drops. On direct questioning, he admitted to using fixed combination tobramycin 0.3%/dexamethasone 0.1% eye-drops frequently to relieve ocular redness and discomfort in both eyes for 3.5 years without his ophthalmologist's knowledge. Examination disclosed markedly elevated IOP, advanced optic disc cupping and tunnel vision due to steroid-induced glaucoma bilaterally. After cessation of the eye-drops and 2 weeks of antiglaucoma therapy, his IOP returned to normal and his visual field remained stable for 4 years.Our case highlights the danger of habitual self-treatment of prescription medications containing corticosteroids and the importance of taking a detailed medication history in the diagnosis and management of steroid-induced glaucoma., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Vasospastic angina (VSA) can be worsened by oral nonselective beta-blockers. Ophthalmic carteolol eye drops are nonselective beta-blockers and effective against glaucoma and ocular hypertension. Systemic effects of ophthalmic beta-blockers on VSA have not yet been reported. We herein report a case of VSA that developed after a patient started carteolol eye drops for ocular hypertension. Even though benidipine, a calcium channel blocker, was started, a VSA attack with incessant non-sustained ventricular tachycardia occurred. Once the carteolol eyedrops were discontinued, the VSA resolved. This case demonstrates that carteolol eye drops can induce life-threatening VSA.

Background: Painful paronychia and pseudopyogenic granuloma (PG) are common adverse drug reactions (ADRs) associated with the use of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) to treat non-small cell lung cancer (NSCLC). Multiple local management approaches have been tested with unsatisfactory results. We have introduced an occlusion therapy technique through which available topical drugs for longer than 2 years., Methods: Based on the cancer registry and case management system of our hospital, from July 2019 to July 2020, we retrospectively enrolled patients with NSCLC who were treated with EGFR-TKIs and received applications of 0.5% timolol ophthalmic solution (TIMOPTOL XE 0.5%®) combined with a neomycin/tyrothricin ointment ( Biomycin ®) using the occlusion method to treat paronychia or PG., Results: A total of 22 patients were enrolled, with a mean age of 66.5 years, most of whom were women (72.7%). Periungual lesion-related pain was reported by all patients, and periungual bleeding and PG were reported in 14% (3/22) and 64% (14/22) of patients, respectively. After the occlusion therapy application of timolol ophthalmic solution combined with neomycin/tyrothricin ointment twice daily, the overall response rate was 83.3%, including complete response in 18% (4/22) of cases and partial response in 68% (15/22) of cases., Conclusion: We presented an occlusion method using available topical beta-blockers and antibiotic ointment for EGFR-TKI-induced paronychia and PG in Taiwan. The result is favorable. Further randomized control trial is urgent to validate our findings.

Purpose: Ripasudil is a class of drug which alters the trabecular meshwork to increase the aqueous outflow and has been shown to be effective in pseudoexfoliative glaucoma (PXF G). This study aimed at assessing the efficacy and safety profile of ripasudil as an adjunct treatment in patients with PXF G at maximal tolerated antiglaucoma medications., Methods: In this prospective, interventional study, 40 patients with PXF G were enrolled between May 2021 and Jan 2022. Ripasudil 0.4% was started as an adjunctive drug to the ongoing antiglaucoma medications. On follow-up visits at 1, 3, and 6 months, the visual acuity, intraocular pressure (IOP), anterior segment, and fundus findings were evaluated. The premedication and postmedication IOP values were compared by paired t-test, and a P-value <0.05 was considered statistically significant., Results: Average age at recruitment was 60.02 ± 8.74 years. Baseline premedication IOP was 25.375 ± 3.276 mmHg. IOP reduction at 6 months was found to be statistically significant in all patients, with the maximal response being 24.13%. Also, 87.5% (35/40) of patients reached target IOP or even lower IOP at the end of study. There was no statistically significant association between the PXF grade and IOP. However, the grade of inferior iridocorneal angle pigmentation was found to be higher in eyes with elevated IOP (P < 0.05). Only three patients developed conjunctival hyperemia as an adverse reaction, which was mild and transient., Conclusion: Ripasudil showed additional IOP-lowering effect with other antiglaucoma medications and exhibited no significant side effects., Competing Interests: None

Purpose: The purpose of this study was to assess the dose-response effects of low-dose atropine on myopia progression and safety in pediatric subjects with mild-to-moderate myopia., Methods: This phase II, randomized, double-masked, placebo-controlled study compared the efficacy and safety of atropine 0.0025%, 0.005%, and 0.01% with placebo in 99 children, aged 6-11 years, with mild-to-moderate myopia. Subjects received 1 drop in each eye at bedtime. The primary efficacy endpoint was change in spherical equivalent (SE), while secondary endpoints included changes in axial length (AL) and near logMAR (logarithm of the minimum angle of resolution) visual acuity and adverse effects., Results: The mean±SD changes in SE from baseline to 12 months in the placebo and atropine 0.0025%, 0.005%, and 0.01% groups were -0.55±0.471, -0.55±0.337, -0.33±0.473, and -0.39±0.519 D, respectively. The least squares mean differences (atropine-placebo) in the atropine 0.0025%, 0.005%, and 0.01% groups were 0.11 D ( P =0.246), 0.23 D ( P =0.009), and 0.25 D ( P =0.006), respectively. Compared with placebo, the mean change in AL was significantly greater for atropine 0.005% (-0.09 mm, P =0.012) and 0.01% (-0.10 mm, P =0.003). There were no significant changes in near visual acuity in any of the treatment groups. The most common ocular adverse events were pruritus and blurred vision, each occurring in 4 (5.5%) atropine-treated children. Changes in mean pupil size and amplitude of accommodation were minimal., Conclusions: Atropine doses of 0.005% and 0.01% effectively reduced myopia progression in children but no effect was noted with 0.0025%. All doses of atropine were safe and well tolerated., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 Asia-Pacific Academy of Ophthalmology.

Abstract: Emerging monoclonal antibody therapies are assuming greater importance in the management of severe and refractory forms of immunity-driven and oncological disorders. However, some have been found to induce adverse ocular events (AOEs) leading to discontinuation of treatment or additional multidisciplinary management. We present the current knowledge concerning AOEs associated with 3 monoclonal antibody therapies: dupilumab, tralokinumab, and belantamab mafodotin. We examine the manifestations of their AOEs, proposed pathophysiological mechanisms, and current treatment recommendations. We identified and reviewed all studies for dupilumab, tralokinumab, and belantamab mafodotin using the keywords "dupilumab," "tralokinumab," "belantamab mafodotin," "conjunctivitis," and "keratopathy" from January 2016 to November 2021. Conjunctivitis was the most frequently reported AOE in patients with atopic dermatitis receiving dupilumab or tralokinumab. Mild cases were managed with warm compresses for associated meibomian gland dysfunction, artificial tears, and antihistamine/mast cell stabilizer eye drops. In more severe cases, additional anti-inflammatory therapy, with corticosteroid eye drops or ointments, or topical calcineurin inhibitors-such as tacrolimus or ciclosporin-were required. Patients with resistant or refractory multiple myeloma treated with belantamab mafodotin often developed keratopathy, which could necessitate contact lens fitting, or for cycles of belantamab mafodotin to be delayed., Competing Interests: S.

Purpose: Evaluate the initial ocular safety and tolerability and efficacy of VVN001 Ophthalmic Solution (VVN001), a small-molecule antagonist of lymphocyte function-associated antigen-1 (LFA-1), in subjects with dry eye disease (DED)., Methods: This was a multi-center, double-masked, randomized, dose-response, vehicle-controlled, parallel-group study conducted in 170 subjects with DED. Subjects were randomized to receive VVN001 (1% or 5%) or its vehicle, twice-daily in both eyes for 84 days. The primary outcome measure was inferior region corneal fluorescein staining (iCFS, 0-4 scale) at Day 84. Visual Analogue Scale eye dryness (VAS, 0-100 scale) was a secondary outcome., Results: The primary and first secondary outcomes were not met. At Day 84 treatment effects in favor of VVN001 5% relative to its vehicle for iCFS were 0.29 units (p = 0.054), and for VAS were 3.18 units (p = 0.533). In other secondary outcomes, treatment effects in favor of VVN001 5% relative to its vehicle were seen in total CFS (1.61 units, 0-20 scale, p = 0.004) and Schirmer score (1.77 and 2.32 mm, p = 0.049 and p = 0.17 at Days 14 and 28 respectively). Adverse events of incidence 5% or greater in either active treatment group were instillation site pain (3/57, 5.3%), dysgeusia (3/56, 5.4%) and urinary tract infection (3/57, 5.3%)., Conclusions: There were no major safety issues of note. Appropriately powered studies will be required with a priori selection of the efficacy endpoints to evaluate VVN001's therapeutic potential., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Importance: Early onset of myopia is associated with high myopia later in life, and myopia is irreversible once developed., Objective: To evaluate the efficacy of low-concentration atropine eyedrops at 0.05% and 0.01% concentration for delaying the onset of myopia., Design, Setting, and Participants: This randomized, placebo-controlled, double-masked trial conducted at the Chinese University of Hong Kong Eye Centre enrolled 474 nonmyopic children aged 4 through 9 years with cycloplegic spherical equivalent between +1.00 D to 0.00 D and astigmatism less than -1.00 D. The first recruited participant started treatment on July 11, 2017, and the last participant was enrolled on June 4, 2020; the date of the final follow-up session was June 4, 2022., Interventions: Participants were assigned at random to the 0.05% atropine (n = 160), 0.01% atropine (n = 159), and placebo (n = 155) groups and had eyedrops applied once nightly in both eyes over 2 years., Main Outcomes and Measures: The primary outcomes were the 2-year cumulative incidence rate of myopia (cycloplegic spherical equivalent of at least -0.50 D in either eye) and the percentage of participants with fast myopic shift (spherical equivalent myopic shift of at least 1.00 D)., Results: Of the 474 randomized patients (mean age, 6.8 years; 50% female), 353 (74.5%) completed the trial. The 2-year cumulative incidence of myopia in the 0.05% atropine, 0.01% atropine, and placebo groups were 28.4% (33/116), 45.9% (56/122), and 53.0% (61/115), respectively, and the percentages of participants with fast myopic shift at 2 years were 25.0%, 45.1%, and 53.9%. Compared with the placebo group, the 0.05% atropine group had significantly lower 2-year cumulative myopia incidence (difference, 24.6% [95% CI, 12.0%-36.4%]) and percentage of patients with fast myopic shift (difference, 28.9% [95% CI, 16.5%-40.5%]). Compared with the 0.01% atropine group, the 0.05% atropine group had significantly lower 2-year cumulative myopia incidence (difference, 17.5% [95% CI, 5.2%-29.2%]) and percentage of patients with fast myopic shift (difference, 20.1% [95% CI, 8.0%-31.6%]). The 0.01% atropine and placebo groups were not significantly different in 2-year cumulative myopia incidence or percentage of patients with fast myopic shift. Photophobia was the most common adverse event and was reported by 12.9% of participants in the 0.05% atropine group, 18.9% in the 0.01% atropine group, and 12.2% in the placebo group in the second year., Conclusions and Relevance: Among children aged 4 to 9 years without myopia, nightly use of 0.05% atropine eyedrops compared with placebo resulted in a significantly lower incidence of myopia and lower percentage of participants with fast myopic shift at 2 years. There was no significant difference between 0.01% atropine and placebo. Further research is needed to replicate the findings, to understand whether this represents a delay or prevention of myopia, and to assess longer-term safety., Trial Registration: Chinese Clinical Trial Registry: ChiCTR-IPR-15006883.

Beta-blockers have been prohibited by the World Anti-Doping Agency (WADA) in certain sports, but insufficient research data make it difficult to distinguish between therapeutic uses or misuses. This study aimed at investigating the urinary excretion pattern following beta-blocker ophthalmic drops and the potential risk of constituting an adverse analytical finding (AAF) in sports. Prescribed timolol and carteolol ophthalmic drops were used in healthy participants and glaucoma patients. The urine samples were then collected to investigate the urinary excretion pattern following acute and chronic administration of the above beta-blocker ophthalmic drops. The liquid chromatograph-tandem mass spectrometry method was applied for measuring urinary beta-blockers. Our results demonstrated that the levels of both urinary timolol and carteolol exceeded the minimum reporting levels (MRL) following acute and chronic administration. The highest levels of urinary timolol and carteolol observed in the present study were 255.7 and 923.8 ng/ml, respectively. Regarding the acute administration of timolol ophthalmic drop, 26.19 (11/42) of urine samples were detected with timolol higher than the MRL in timed and random sampling. In contrast, the acute administration of carteolol ophthalmic drops made the carteolol levels higher than the MRL among most urine samples. On the other hand, 36.36% (4/11) of urine samples were detected with beta-blockers higher than the MRL during the chronic administration of timolol and carteolol ophthalmic drops. In the context of receiving ophthalmic beta-blocker medications, the present study has highlighted the potential risk of constituting an AAF in specific sports and suggests strengthening athletes' awareness of therapeutic use exemptions., (© 2022 John Wiley & Sons Ltd.)

Background: Eye examinations for ROP screening in preterm newborns are characterized by two main problems: infection control and poor tear secretion. Therefore, in order to reduce the risk of ocular infection and to protect the ocular surface, netilmicin eye drops are usually used after the exams. The purpose of our study was to evaluate the safety and tolerability of ozonated-oils eyedrops during the eye examination of preterm babies in the screening for ROP, sparing the use of antibiotics eyedrops., Methods: All newborn infants that needed to be screened for ROP were divided into two groups: in group A we used topical netilmicin eye drops and in group B ozonated-oils eyedrops. We looked for any sign of conjunctival injection and chemosis, infectious conjunctivitis, blepharoconjunctivitis, erythema, and edema of the eyelids., Results: A total of 162 adverse effects out of 3546 examinations (4,5%) were reported acutely: in group A (1778 examinations), they consisted of 47 reactive conjunctivitis, 3 cases of blepharoconjunctivitis, 30 of eyelids swelling, and 3 infectious conjunctivitis, compared to 39 cases of conjunctival injection, 3 blepharoconjunctivitis, 33 eyelids swelling and 4 infectious conjunctivitis in group B (1768 examinations). No significant differences were found in the comparison of the two groups., Conclusions: Ozonated-oils eyedrops should be considered a valid and safe alternative for the lubrification of the ocular surface and an adjuvant strategy to further minimize the risk of microbial contamination during screening for ROP.

Purpose: The goal of this study was to compare topical dexamethasone 1.5% in a novel formulation (OCS-01) once daily and BID versus vehicle for the treatment of inflammation and pain after cataract surgery., Methods: This was a Phase II, double-masked, vehicle-controlled, randomized multicenter study. Adult patients with planned unilateral uncomplicated cataract surgery were randomized to receive OCS-01 once daily (n = 51), OCS-01 BID (n = 51), or matching vehicle (n = 51) for 15 days postsurgery. Primary end points were absence of anterior chamber cells (ACC; cells = 0) at Day 15 and absence of pain (score of "0") at postoperative Day 4. The Pearson χ 2 test with a two-sided alpha = 0.1 was used to compare treatments. Safety was assessed in terms of adverse events and changes in intraocular pressure., Findings: Treatment arms were generally similar in their baseline characteristics, with mean age ranging from 66 to 68 years, the proportion of male patients ranging from 29% to 37%, and 82% to 92% of each arm being White. On Day 15, a greater reduction in the percentage of eyes with ACC grade 0 was observed in the OCS-01 once daily (51%) and BID (66.7%) arms than in the vehicle arm (19.6%) (P = 0.0009 and P < 0.0001, respectively, using a Pearson χ 2 test). On Day 4, the percentage of eyes with no pain was 72.5% (OCS-01 once daily), 62.7% (OCS-01 BID), and 45.1% (vehicle); statistical significance was reached for OCS-01 once daily (P = 0.005) and OCS-01 BID (P = 0.074) compared with vehicle. OCS-01 was well tolerated. A higher proportion of treatment-emergent adverse events, including ocular adverse events, were reported for the placebo group than for either OCS-01 group., Implications: OCS-01 once daily and BID were more effective than vehicle and well tolerated in the treatment of inflammation and pain after cataract surgery., Clinicaltrials: gov identifier: NCT04130802., Competing Interests: Declaration of Interest Oculis were involved in the study design; the collection, analysis, and interpretation of data; in the writing of the report; and in the decision to submit the article for publication.

Over the past 15 years, the increasing nonmedical use of tropicamide ophthalmic drops has been reported in Europe, coinciding with an increase in opioid addiction and drug-related mortality. Although tropicamide is generally known as a cheap alternative to heroin in Eastern Europe, it still appears to be a relatively new phenomenon that has arisen over the last decade. A narrative review was conducted of all the relevant sources published in more than five countries between January 1, 1975 and January 10, 2021. For bibliographic accuracy, the materials published in Russian and Italian were professionally translated to English. During the preparation of this report, we were able to interview five Russian-speaking patients who injected tropicamide in the past and we discuss another case of intravenous tropicamide use. This review was acknowledged by the institutional review board of the University of Missouri-Kansas City. All patients interviewed at the Unica Medical Center consented for their clinical information to be reported in a medical publication. We analyzed data from 50+ various sources and covered a variety of drug-related issues, including information on the extent, patterns, and trends in tropicamide use, its health consequences, and other clinical findings. The information provided in this article may help providers better detect tropicamide abuse and incorporate new rehabilitation strategies into the management of these patients., Competing Interests: JB’s institution has received funding from Genzyme to support his work.

Myopia is the leading cause of low vision worldwide and can lead to significant pathological complications. Therefore, to improve patient outcomes, the field continues to develop novel interventions for this visual disorder. Accordingly, this first-in-human study reports on the safety profile of a novel dopamine-based ophthalmic treatment for myopia, levodopa/carbidopa eye drops. This phase I, first-in-human, monocenter, placebo-controlled, double-blind, paired-eye, multidose, randomized clinical trial was undertaken in healthy adult males aged 18-30 years (mean age 24.9 ± 2.7) at the University of Canberra Eye Clinic, Australia. Participants were randomly assigned to receive either a low (1.4 levodopa:0.34 carbidopa [μmoles/day], n = 14) or standard dose (2.7 levodopa:0.68 carbidopa [μmoles/day], n = 15) of levodopa/carbidopa eye drops in one eye and placebo in the fellow eye once daily for 4 weeks (28 days). Over this 4-week trial, and after a 4-month follow-up visit, levodopa/carbidopa treatment had no significant effect on ocular tolerability and anterior surface integrity, visual function, ocular health, refraction/ocular biometry, and did not induce any non-ocular adverse events. These results indicate that topical levodopa/carbidopa is safe and tolerable to the eye, paving the way for future studies on the efficacy of this novel ophthalmic formulation in the treatment of human myopia. The findings of this study have implications not only for the treatment of myopia, but in a number of other visual disorders (i.e., amblyopia, diabetic retinopathy, and age-related macular degeneration) in which levodopa has been identified as a potential clinical intervention., (© 2022 The Authors.

Purpose : To compare the performance and safety of 2 tear substitutes containing sodium hyaluronate (SH); one containing 0.15% SH and polyethylene glycol (PEG) 8000, and the other containing 0.18% SH. Methods : In this multicenter, randomized, investigator-masked, noninferiority trial, 83 patients with moderate or severe dry eye disease underwent a 2-week washout, and were then randomly assigned (1:1) to receive SH plus PEG tear substitute ( n  = 45) or comparator SH tear substitute ( n  = 38) 3-6 times daily for 3 months. The primary performance endpoint was the change from baseline in the ocular surface fluorescein staining (OSFS) score on day 28 in the per-protocol (PP) population, according to the 15-point Oxford Scheme, with a noninferiority margin of 2. Results: Both groups improved significantly in terms of signs and symptoms. Among the 78 patients without major protocol deviations (the PP population), the OSFS score decreased by 2.9 ± 2.0 on day 28 from 5.4 ± 1.3 at baseline in the SH plus PEG group and by 2.3 ± 2.2 from 5.2 ± 1.4 in the comparator group (95% confidence interval of the difference: -1.2 to 0.3), demonstrating noninferiority. On day 90, the improvement in OSFS scores was significantly greater in the SH plus PEG group ( P  = 0.0002). The safety profiles were satisfactory in both groups. Conclusion: SH plus PEG tear substitute was noninferior to SH tear substitute in the studied population and may provide additional benefits in the long term. ClinicalTrials.gov ID: NCT02975102.

Objective: This study served to compare the degree of adrenocortical suppression following a 2-week administration of loteprednol etabonate (LE) and prednisolone acetate (PA) ophthalmic drops., Procedures: In this prospective double-masked triple-crossover study, 21 clinically healthy dogs were randomized to receive loteprednol etabonate ophthalmic suspension 0.5%, prednisolone acetate ophthalmic suspension 1%, or artificial tears (AT). Each group (LE, PA, and AT) received one drop in each eye every 12 h for 2 weeks, followed by a 3-week washout period between treatment blocks. ACTH stimulation tests were performed before and after each treatment block. Serum cortisol samples were drawn before and 60 min after administration of 1 μg/kg cosyntropin IV. Repeated-measurement ANOVA followed by a Tukey's multiple comparisons test (or a Friedman test followed by a Dunn's multiple comparisons test) were used to compare pre- and post-treatment cortisol values between each group. A p-value of ≤.05 was considered significant., Results: A total of 18 dogs completed the study. Prestimulation cortisol values were lower in the PA group compared to the LE (p = .0106), but not AT (p = .0589) groups, and post-stimulation cortisol values were lower in the PA group than either LE (p = .0005) or AT (p = .0002) groups. There was no significant difference detected in pre- or post-stimulation cortisol values after the treatment periods between LE and AT., Conclusions: Based on the reduced suppression of cortisol values, LE caused significantly less hypothalamic-pituitary-adrenal axis suppression than PA. A topical steroid with minimal adrenocortical suppression, such as LE, may be favorable in patients where systemic glucocorticoid effects should be avoided., (© 2022 American College of Veterinary Ophthalmologists.)

Background and Objectives: To evaluate the safety, tolerability, and biological activity of a topical selective integrin inhibitor (OTT166) eyedrop administered BID for diabetic retinopathy (DR) and diabetic macular edema (DME)., Study Design/materials and Methods: A prospective, multicenter, randomized, double-masked Phase 1b study. Subjects with nonproliferative DR and DME with central subfield thickness (CST) &gt; 325 microns were randomized to OTT166 eyedrops (2.5% or 5%) BID for 28 days. Subjects were followed for an additional 28 days after treatment cessation., Results: Forty-four subjects were enrolled. No drug-related serious adverse events (SAEs) and two drug-related adverse events (AEs) were reported. OTT166 was well-tolerated with no evidence of ocular toxicity. Best-corrected visual acuity (BCVA) remained stable. Mean central retinal thickness (CRT) overall was variable: +12.8/+1.8 microns at Day 28 (end of treatment) and -50.3/+5.5 microns at Day 56 (end of study) for the 2.5% and 5% groups, respectively. Median CRT overall demonstrated consistent reduction by end of study: -39.0/-16.5 microns for the 2.5% and 5% groups, respectively. Median responses were greater in the treatment-naïve group (-41.5/-26.0 microns for the 2.5% and 5% groups, respectively). Thirty-seven percent of 'responder' subjects exhibited a mean reduction in CRT of 46.6 microns on optical coherence tomography (OCT) at end of treatment (Day 28) which persisted to end of the study (Day 56) - mean reduction of 67.4 microns, suggesting a durable effect., Conclusion: OTT166 eyedrops were safe, well-tolerated, and demonstrated biological activity in 37% of responders. These results warrant further evaluation of OTT166 eyedrops. &lt;b&gt;[&lt;i&gt;Ophthalmic Surg Lasers Imaging Retina&lt;/i&gt; 2022;53:553-560.]&lt;/b&gt;.

Purpose: To confirm the efficacy and safety of a novel ophthalmic cyclosporine A gel (CyclAGel, 0.05% CsA) in treating patients with moderate-to-severe dry eye disease (DED)., Patients and Methods: The COSMO trial was a randomized, multicenter, double-masked, vehicle-controlled, phase III trial. Patients with moderate-to-severe DED were enrolled in 37 hospitals in China between November 2020 and April 2021. Eligible patients were randomized 1:1 to receive CyclAGel 0.05% or vehicle eye drops once nightly (QD). The primary endpoint was the proportion of subjects with at least a 1-point improvement in ICSS at day 84. Treatment-emergent adverse events (TEAEs) were recorded., Results: The full analysis set (FAS) included 315 and 312 participants in the CyclAGel and vehicle groups, respectively. The primary efficacy endpoint was achieved. The proportion of subjects with at least a 1-point improvement in ICSS from baseline to day 84 was significantly higher in the CyclAGel group than in the vehicle group (73.7% [232/315] vs 53.2% [166/312], P<0.0001). Significant improvements relative to the vehicle were also observed in the ICSS and Oxford scale scoring of corneal and conjunctival fluorescein staining at day 14, 42, and 84. The Schirmer tear test results were significantly higher in the CyclAGel group than in the vehicle group on days 14 and 84 (all P<0.05). The CyclAGel 0.05% was well tolerated, and the TEAEs were mostly mild. The most frequent treatment-related TEAE was eye pain (6.9% vs 1.6% in the CyclAGel and vehicle groups, respectively). No serious treatment-related TEAEs were reported., Conclusion: Clinically and statistically significant improvements in ICSS, tear production, and symptoms were observed in participants administered CyclAGel 0.05% QD for moderate-to-severe DED. CyclAGel 0.05% QD is a new effective, safe, and well-tolerated therapeutic option that might bring additional benefits of convenience and compliance as a once-A-day treatment for DED., Competing Interests: Xiaoyi Li is affiliated with Zhaoke Ophthalmology Ltd.

Intracameral phenylephrine is commonly used in ophthalmic surgery as an alternative or supplement to mydriatic eye drops; hence, the importance of an evidence-based understanding of its risk-benefit profile is vital. We performed a comprehensive search in the PubMed, Google Scholar, and Cochrane databases for published studies and case reports relating to the use of intracameral phenylephrine. Articles from 1958 to 2021 with the following keywords were used: "intracameral phenylephrine," "intracameral mydriatics," "phenylephrine," "pupil dilation," "complications." Intracameral phenylephrine was first used in 2003 as an alternative to topical mydriatics. Since then, it is being increasingly used with a variety of benefits, including rapid onset of mydriasis, and cost-effectiveness. There are various case reports, however, of ocular and systemic complications associated with intracameral phenylephrine such as generation of free radicals, toxic anterior segment syndrome, inconsistent pupillary dilation during surgery, and ventricular fibrillation. Alternatives to intracameral phenylephrine such as iris hooks, a Malyugin ring, intracameral epinephrine, and intracameral tropicamide were compared with intracameral phenylephrine. Intracameral phenylephrine appears to have a good safety profile., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Purpose: Dry eye disease is a multifactorial disorder that affects the ocular surface, with symptoms including ocular irritation, impaired vision, and pain. Nicotinic acetylcholine receptor (nAChR) agonists are novel treatments for dry eye disease; this study investigates the nAChR agonist OC-02 (simpinicline solution) as an aqueous nasal spray., Methods: PEARL (Clinical Trial to Evaluate the Efficacy of OC-02 Nasal Spray on Signs and Symptoms of Dry Eye Disease) was a Phase II study that evaluated the efficacy and safety of OC-02 (simpinicline solution) nasal spray (OC-02 SNS) in adult patients with dry eye disease. Patients ≥22 years of age were eligible if they had an Ocular Surface Disease Index score ≥23, corneal fluorescein staining score ≥2 in >1 region or ≥4 for all regions, or Schirmer test score (STS) ≤10 mm; there were no restrictions on eye dryness score (EDS). Patients (N = 165) were randomly assigned 1:1:1:1 to vehicle (control; n = 42) or OC-02 SNS (0.11 mg, 0.55 mg, or 1.1 mg; n = 41 per group) and received a single dose of study drug (100 µL using a nasal spray atomizer) at visit 1 and visit 2 (15-19 days after visit 1). Primary efficacy outcomes were change in the STS from baseline to immediately after treatment administration (visit 1) and change in the EDS from before to 5 minutes after treatment during controlled adverse environment exposure (visit 2)., Findings: Baseline demographic and ocular clinical characteristics were similar across all groups. Single-dose OC-02 SNS improved the signs and symptoms of dry eye disease. For the STS, statistically significant and dose-dependent improvements were found from before to after treatment with OC-02 SNS versus vehicle (least-squares mean change from baseline: vehicle, 3.0 mm; 0.11 mg OC-02 SNS, 9.0 mm; 0.55 mg, 17.5 mm; and 1.1 mg, 19.6 mm). For EDS, statistically significant and dose-dependent improvements were found from before to 5 minutes after treatment with higher doses of OC-02 SNS versus vehicle (least-squares mean change from baseline: vehicle, -6.5; 0.11 mg OC-02 SNS, -9.4; 0.55 mg, -17.4; and 1.1 mg, -20.7). OC-02 SNS was well tolerated: only 2 ocular adverse events were reported (eye pruritis and keratitis), and the most common nonocular events were cough and throat irritation., Implications: Single-dose OC-02 SNS over a range of doses immediately and significantly increased tear production and improved eye dryness. Together with previous studies of OC-01 (varenicline solution) nasal spray, our findings suggest that agonist stimulation of nAChRs in the nasal cavity is a valid and effective mechanism to elicit natural tear production in patients with dry eye disease., Clinicaltrials: gov identifier: NCT03452397., (Copyright © 2022 The Authors.

Introduction: DE-089C is a newly developed long-acting formulation of diquafosol ophthalmic solution with less frequent administration (three times daily) than the currently approved and clinically used diquafosol ophthalmic solution (six times daily), hereinafter referred to as DQS. DE-089C is desirable for achieving better patient adherence in clinical practice for dry eye therapy. The objective of this study was to confirm the efficacy and safety of DE-089C in patients with dry eye compared to placebo., Methods: This randomized, multicenter, double-masked, placebo-controlled, parallel-group phase 3 study was conducted in Japan. Patients with aqueous-deficient dry eye satisfying Schirmer's test I results ≤ 5 mm/5 min were included. A total of 337 patients with dry eye were randomized in an equal ratio to treatment with DE-089C or placebo ophthalmic solution, three times daily for 4 weeks. The primary endpoint for efficacy was change in fluorescein corneal staining score from baseline to week 4. The incidence of adverse drug reactions was investigated for safety evaluation., Results: The background characteristics of patients in the two groups were similar. Primary endpoint of change in fluorescein corneal staining score at week 4 in the DE-089C group was significantly improved compared with the placebo group (least squares mean difference - 0.51, 95% CI - 0.754 to - 0.269, P < 0.0001). The secondary endpoint of the Lissamine green conjunctival staining score was also significantly improved in the DE-089C group compared to that in the placebo group, while other secondary endpoints were not achieved in this study. Commonly (incidence ≥ 1%) reported adverse drug reactions in the DE-089C group were eye irritation (3.6%) and eye discharge (1.8%) with mild severity, and the incidences of these two events were not higher than those in previous clinical studies on DQS., Conclusion: The efficacy and safety of DE-089C administered three times daily at half the dosage of DQS in patients with dry eye were confirmed in this study., Trial Registration: Japan Pharmaceutical Information Center ID, JapicCTI-205177., (© 2022.
