We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered. [ABSTRACT FROM AUTHOR]

SignificanceHemolacria (bloody tears) is a rare clinical presentation with varied underlying etiologies. Thorough clinical evaluation is essential to diagnosis and management.PurposeThis study aimed to report unilateral hemolacria in a known contact lens wearer with an occult, palpebral, conjunctival pyogenic granuloma and review the literature.Case reportA 21-year-old female contact lens wearer presented to the clinic after three episodes of sudden painless bloody tears from the right eye. She was referred to the oculoplastic clinic for evaluation. On everting her right upper lid, a fleshy, nontender, ovoid, pedunculated mass was found attached to the palpebral conjunctiva of the right, nasal, upper tarsus. Surgical excision was performed in the office, and pathological examination of the lesion was consistent with pyogenic granuloma.ConclusionsUnilateral hemolacria should raise clinical suspicion for a hidden conjunctival lesion such as pyogenic granuloma, although other more sinister causes of hemolacria must also be considered. Thorough evaluation including eyelid eversion is critical in identifying and managing occult conjunctival lesions.

Purpose: The objective of this study was to evaluate the prevalence of premalignant and malignant lesions in patients clinically diagnosed with pterygium who underwent excision procedures performed by 1st-year residents in ophthalmology at a teaching hospital between 2018 and 2021. Methods: A cross-sectional analysis was conducted on 274 medical records of patients diagnosed with pterygium who underwent excision procedures from 2018 to 2021 at Hospital PUC-Campinas in Campinas, São Paulo, Brazil. Fifty-four medical records were excluded due to missing essential data. Among the 220 records included for analysis, 239 histopathological results were considered, as 19 patients underwent pterygium excision in both eyes. Results: Out of 239 histopathological results analyzed, 236 (98.74%) were compatible with pterygium, 2 (0.8%) with epithelial dysplasia, and 1 (0.4%) with actinic keratosis. Conclusion: A histopathological study is essential for the accurate differential diagnosis of pterygium. Although the frequency of ocular surface squamous neoplasia is low, premalignant and malignant lesions must be ruled out. Correct diagnosis must be made to allow proper follow-up of the patients and prevent life-threatening lesions.

BackgroundTo determine if there is a difference in the quantity of microbial flora of the conjunctiva in individuals practicing head submersion ("dunk") versus no head submersion ("no-dunk") during hot tub use.MethodsIn this double-blind randomized clinical trial, healthy volunteers aged ≥ 18 years were recruited. Participants were randomized to head submersion versus no head submersion during a 15-minute hot tub soak. Study personnel, masked to the dunk or no-dunk group assignment, obtained conjunctival cultures before and immediately after hot tub use. De-identified specimens were submitted to the clinical microbiology laboratory for culture and analysis. The main outcome measure was the difference in the quantity of organisms cultured from the conjunctiva before and after hot tub exposure, as determined using a defined ordinal scale. A two-tailed Student's t-test was performed to compare the total microbial colony counts between the two arms. Simpson's diversity was used to measure the changes in organism diversity between the arms.ResultsOf 36 enrolled subjects, 19 were randomly assigned to the dunk and 17 were assigned to the no-dunk groups. Water samples obtained from all hot tubs were culture negative. Eleven of 19 eyes (58%) from the dunk group and eight of 17 eyes (47%) from the no-dunk group had negative conjunctival bacterial cultures before and after hot tub exposure. However, six of 19 eyes (32%) and four of 17 eyes (24%) of the dunk and no-dunk groups, respectively, were culture-positive after, but not before hot tub exposure. The quantity of organisms before and after hot tub exposure was not significantly different between the two arms (P = 0.12). However, the dunk group only showed a small increase in the quantity of organisms after as compared to before hot tub use (P = 0.03). None of the samples from subjects or hot tubs were culture-positive for Acanthamoeba.ConclusionsHead submersion in a public hot tubs during a 15-minute soak does not appear to change conjunctival flora, as determined by culture plate yield, this does not eliminate the association between hot tub use and devastating and painful corneal blindness. Therefore, our recommendation is to remove contact lenses prior to hot tub use, avoid head submersion in a hot tub, and urgently seek ophthalmological help if any eye pain and/or decrease in vision is experienced after hot tub use.

Objectives: To compare the findings of standard clinical assessments and of complementary clinical and laboratory methods for determining whether community‐wide treatment for trachoma is warranted in a remote Queensland community. Design: Three cross‐sectional screening surveys, 2019–2021, complemented by laboratory pathology testing. Setting: Small community in northwest Queensland with geographic and cultural ties to Northern Territory communities where trachoma persists. Participants: Children aged 1–14 years; opportunistic screening of people aged 15 years or more. Main outcome measures: Prevalence of clinical signs of trachoma, Chlamydia trachomatis infection, ocular non‐chlamydial infections, and seropositivity for antibodies to the C. trachomatis Pgp3 protein. Results: During the three surveys, 73 examinations of 58 children aged 1–4 years, 309 of 171 aged 5–9 years, and 142 of 105 aged 10–14 years for trachoma were undertaken, as were 171 examinations of 164 people aged 15 years or more; 691 of 695 examinations were of Aboriginal or Torres Strait Islander people (99%), 337 were of girls or young women (48%). Clinical signs consistent with trachomatous inflammation–follicular were identified in 5–9‐year‐old children 23 times (7%), including in eleven with non‐chlamydial infections and one with a C. trachomatis infection. One child (10–14 years) met the criteria for trachomatous scarring. Two of 272 conjunctival swab samples (all ages) were polymerase chain reaction‐positive for C. trachomatis (0.7%). Two of 147 people aged 15 years or more examined in 2019 had trichiasis, both aged 40 years or more. Seven of 53 children aged 1–9 years in 2019 and seven of 103 in 2021 were seropositive for anti‐Pgp3 antibodies. Conclusions: Despite the prevalence of clinical signs consistent with trachomatous inflammation–follicular among 5–9‐year‐old children exceeding the 5% threshold for community‐wide treatment, laboratory testing indicated that childhood exposure to ocular C. trachomatis is rare in this community. Laboratory testing should be integrated into Australian trachoma guidelines. [ABSTRACT FROM AUTHOR]

AIM: To observe the efficacy of pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation in the treatment of patients with pterygium. METHODS:Prospective controlled study. A total of 102 patients(102 eyes)with pterygium treated in the hospital between October 2015 and October 2019 were selected as study subjects, and they were divided into observation group and control group according to the random number table method, with 51 cases in each group. The control group was treated with pterygium excision combined with amniotic membrane transplantation, and the observation group was given pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation. The perioperative indicators(intraoperative blood loss, surgical time, corneal epithelial repair time)and clinical efficacy at 3mo after surgery were compared between the two groups, and the disease recovery-related indicators [tear film break-up time(BUT), uncorrected visual acuity(UCVA), Schirmer Ⅰ test(SⅠt), corneal astigmatism degree(CAD)] before and 3mo after surgery, postoperative aesthetic degree and recurrence during follow-up were recorded.RESULTS:The corneal epithelial repair time in observation group was shorter than that in control group(4.14±1.35 vs 4.72±1.37d,P0.05). At 3mo after surgery, there was no statistical difference in the effective rate of treatment between the two groups(86.3% vs 78.4%, P>0.05). At 3mo after surgery, the BUT, UCVA and SⅠt in the two groups were significantly enhanced compared with those before surgery(all P0.05). The CAD in the two groups was significantly lower than that before surgery(P0.05). At 3mo after surgery, the scores of dimensions of aesthetic scale for pterygium treatment(ocular recovery, subjective symptoms)were significantly higher in observation group than those in control group(all P0.05). There was no statistically significant difference in recurrence rate between the two groups during follow-up(P>0.05).CONCLUSION: Pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation can effectively treat pterygium and prevent recurrence, and it has faster postoperative recovery and better aesthetic degree compared to pterygium excision combined with amniotic membrane transplantation.

Dysfunction of the meibomian glands alters secreted meibum quantitatively and qualitatively that can lead to damage to the ocular surface epithelium. In response to an unstable tear film cause by meibomian gland dysfunction, ocular surface epithelium is damaged and expresses inflammatory cytokines leading to secondary ocular inflammation. In turn, inflammatory disorders of the palpebral conjunctiva and lid margin may affect the structure and function of meibomian gland. The disorders include allergic conjunctivitis, long-term usage of contact lenses, dermatological diseases that affect conjunctival homeostasis, Stevens-Johnson's syndrome or chemical burning of the ocular surface and lid margin.

Abstract Background The purpose of the study was to evaluate the in vitro antibacterial effect of experimental eye drops with bacteriophages in elimination of Staphylococcus spp. isolated from dogs with bacterial conjunctivitis.. The bacterial material was collected from dogs with independent clinical signs of bacterial conjunctivitis. Staphylococcus spp. were identified by phenotypic and genotypic methods (MALDI-TOF MS mass spectrometry). Antibiotic resistance was determined by the disc-diffusion method. Phage activity (Plaque forming units, PFU) was determined on double-layer agar plates. Phages with lytic titres > 108 PFU were used to prepare eye drops. The stability of the antibacterial titre was evaluated for preparations stored in sealed bottles as well as after opening and reclosing. Results The tests confirmed the occurrence of Staphylococcus spp. strains as etiological agents of bacterial conjunctivitis in dogs. A high percentage of strains were resistant to more than three antibiotics. The experimental phage eye drops used in the study exhibited 100% efficacy in vitro against the tested Staphylococcus isolates. Particularly noteworthy is the long duration of activity and constant antibacterial lytic titre of ≥108 PFU/mL of two eye drop solutions, nos. 7 and 12, after the bottle had been opened (21 days) and after hermetically sealed packaging (28 days) at 4–8 °C. Conclusions The results represent the first stage of research and require continuation in vivo. If positive effects are obtained in animals, the results can be used in applied research in humans and animals.

IntroductionLatanoprostene bunod (LBN) is a novel nitric oxide (NO)-donating prostaglandin F2α analog. We evaluated the long-term safety and intraocular pressure (IOP)-lowering efficacy of LBN ophthalmic solution 0.024% over 1 year in Japanese subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).MethodsThis was a single-arm, multicenter, open-label, clinical study. Subjects aged 20 years and older with a diagnosis of OAG or OHT instilled 1 drop of LBN ophthalmic solution 0.024% in the affected eye(s) once daily in the evening for 52 weeks and were evaluated every 4 weeks. Safety assessments included vital signs, comprehensive ophthalmic exams, and treatment-emergent adverse events (AEs). Absolute and percent reductions from baseline in IOP were also determined.ResultsOf 130 subjects enrolled, 121 (93.1%) completed the study. Mean age was 62.5 years, and mean (standard deviation) baseline IOP was 19.6 (2.9) and 18.7 (2.6) mmHg in study eyes and treated fellow eyes, respectively. Overall, 76/130 (58.5%) and 78/126 (61.9%) subjects experienced ≥1 AEs in study eyes and treated fellow eyes, respectively. In both study eyes and treated fellow eyes, the most common AEs were conjunctival hyperemia, growth of eyelashes, eye irritation, and eye pain. At 52 weeks, 9% of treated eyes had an increase in iris pigmentation compared with baseline based on iris photographs. No safety concerns emerged based on vital signs or other ocular assessments. Mean reductions from baseline in IOP of 22.0% and 19.5% were achieved by week 4 in study and treated fellow eyes, respectively. These reductions were maintained through week 52 (P

: Clinician-scientists bridge the gap between basic research and patient care. At the 2012 Annual Meeting, a symposium highlighting the application of cutting-edge optometric research within the anterior segment was held to present and discuss some of the recent basic scientific advances that will both shape and guide the development of future clinical care practices. This article summarizes this work, bringing together four experts, all clinician-scientists in the field of cornea and ocular surface. Collectively, this work provides new insights to clinicians and researchers alike, as well as brings forth a greater appreciation of the impact of ongoing optometric bench research in advancing clinical care.

With the introduction of silicone hydrogel (SiHy) lenses over a decade ago, clinicians have seen both improvements and challenges in contact lens (CL) wear. Regardless of lens design or material, the presence of a CL on the ocular surface induces mechanical complications. Although some of these complications have diminished in frequency and severity with newer generations of SiHy lenses, others persist at previously reported levels. The aim of this review is to provide up-to-date information on mucin balls, superior epithelial arcuate lesions, corneal erosions, CL-induced papillary conjunctivitis, conjunctival epithelial flaps, lid wiper epitheliopathy, and meibomian gland dropout. The conclusions in this review should provide a sound basis for identifying the future areas of research to help minimize mechanically driven adverse events during CL wear with SiHy lenses.

Implantation of glaucoma drainage devices is a valuable therapeutic option, particularly in children with glaucoma refractory to primary surgical treatment. Glaucoma drainage devices are typically used when conjunctival scarring hampers filtration surgery or prior angle procedures are not effective in controlling intraocular pressure. Despite known complications, the use of glaucoma drainage devices in children has increased in recent years, even as the primary surgical option. In this review, we evaluate the results of recent studies involving the implantation of glaucoma drainage devices in children, discussing new advances, and comparing the success rates and complications of different devices.

Purpose: To evaluate the long-term visual acuity (VA) outcome of cataract surgery in inflammatory eye disease., Setting: Tertiary care academic centres., Design: Multicentre retrospective cohort study., Methods: A total of 1741 patients with non-infectious inflammatory eye disease (2382 eyes) who underwent cataract surgery while under tertiary uveitis management were included. Standardised chart review was used to gather clinical data. Multivariable logistic regression models with adjustment for intereye correlations were performed to evaluate the prognostic factors for VA outcomes. Main outcome measure was VA after cataract surgery., Results: Uveitic eyes independent of anatomical location showed improved VA from baseline (mean 20/200) to within 3 months (mean 20/63) of cataract surgery and maintained through at least 5 years of follow-up (mean 20/63). Eyes that achieved 20/40 or better VA at 1 year were more likely to have scleritis (OR=1.34, p<0.0001) or anterior uveitis (OR=2.2, p<0.0001), VA 20/50 to 20/80 (OR 4.76 as compared with worse than 20/200, p<0.0001) preoperatively, inactive uveitis (OR=1.49, p=0.03), have undergone phacoemulsification (OR=1.45 as compared with extracapsular cataract extraction, p=0.04) or have had intraocular lens placement (OR=2.13, p=0.01). Adults had better VA immediately after surgery, with only 39% (57/146) paediatric eyes at 20/40 or better at 1 year., Conclusions: Our results suggest that adult and paediatric eyes with uveitis typically have improved VA following cataract surgery and remain stable thereafter for at least 5 years., Competing Interests: Competing interests: JTR: AbbVie (consultant); Gilead (consultant); Janssen (consultant); Eyevensys (consultant); UpToDate (author/royalties); Pfizer (financial support); Novartis (consultant); Roche (consultant); Alcon Research Institute (financial support); Horizon (financial support and consultant); Revolo (consultant); Neoleukin (consultant); Affibody (consultant); Celgene-Bristol Myers (Data Monitoring Committee); Eli Lilly (Clinical Endpoints Committee).

Currently, the amniotic membrane (AM) has obtained importance due to its ability to reduce inflammation, helping in the healing and epithelialization processes, having antimicrobial and antiviral properties and low immunogenicity. Its indications in ophthalmology have increased considerably in the past two decades. Objective: To describe the basic structure and biological properties of the AM, the components of the extracellular matrix and growth factors, the consequences of different techniques used in its preservation, and sterilization methods for the epithelium removal. To compare the costs of the different preservation solutions currently employed. Study design: literature review. Methods: Research in BVS databases, PubMed, Cochrane, Scielo and Lilacs with keywords: amniotic membrane transplantation, corneal reconstruction, conjunctival diseases. Results: The literature is vast in describing the effects of different agents and techniques used in the preparation of MA, including its preservation, sterilization and desepithelization. The naked membrane is the choice to reconstruct the ocular surface, as it facilitates the healing course. Regarding the preservatives, glycerol is the most used worldwide due its low cost and easy handling. Conclusion: Comparing different techniques guides us in developing a MA preparation protocol for ophthalmic use. The naked membrane facilitates the healing process compared with the presence of epithelial cells. The glycerol is the most used preservation method because of its low cost and easy handling.

PurposeComposed of sheets of cells detached from the underlying conjunctiva, conjunctival epithelial flap (CEF) is a recently reported phenomenon associated with contact lens wear with potential consequences for ocular health. Although CEF is generally asymptomatic, it is not known to what extent it might increase the longer-term risk of discomfort, inflammatory response, or infection. In this study, we use survival analysis methods to obtain unbiased estimates of the probability of developing CEF, the mean survival time free of CEF, and the effects of age, gender, ethnicity, and contact lens type.MethodsTwo hundred four subjects were recruited for a continuous wear (CW) study of silicone hydrogel (SiH) and gas permeable (GP) contact lenses. Subjects were examined by optometrists throughout contact lens adaptation and CW periods. Statistical methods included the Kaplan-Meier nonparametric estimator of the survival function and the Cox proportional hazards model for estimating the relative effects of covariates.ResultsOf the 204 subjects, 72 (35%) developed CEF. In 64% of cases, CEFs were observed bilaterally. The majority of cases (90.3%) presented with CEF in the superior conjunctiva. Mean survival time free of CEF was longer for GP lenses (94.3 days) than for SiH lenses (76.5 days), and the probability of developing CEF was significantly greater for SiH lenses (p = 0.002). Although there was some evidence that women and non-Asians remain free of CEF longer, the effects of age, gender, and ethnicity were not statistically significant.ConclusionsThere was a significantly increased risk of CEF in subjects wearing SiH lenses, compared with GP lenses. Subjects wearing SiH lenses remained free of CEF for a shorter time on average. Further study is needed to determine whether the increased incidence of CEF in CW with SiH lenses poses an increased risk of adverse ocular response or infection.

Background: Trachoma, a neglected tropical disease, is the leading infectious cause of blindness and visual impairment worldwide. Host responses to ocular chlamydial infection resulting in chronic inflammation and expansion of non-chlamydial bacteria are hypothesized risk factors for development of active trachoma and conjunctival scarring.Methods: Ocular swabs from trachoma endemic populations in The Gambia were selected from archived samples for 16S sequencing and host conjunctival gene expression. We recruited children with active trachoma and adults with conjunctival scarring, alongside corresponding matched controls.Findings: In children, active trachoma was not associated with significant changes in the ocular microbiome. Haemophilus enrichment was associated with antimicrobial responses but not linked to active trachoma. Adults with scarring trachoma had a reduced ocular bacterial diversity compared to controls, with increased relative abundance of Corynebacterium. Increased abundance of Corynebacterium in scarring disease was associated with innate immune responses to the microbiota, dominated by altered mucin expression and increased matrix adhesion.Interpretation: In the absence of current Chlamydia trachomatis infection, changes in the ocular microbiome associate with differential expression of antimicrobial and inflammatory genes that impair epithelial cell health. In scarring trachoma, expansion of non-pathogenic bacteria such as Corynebacterium and innate responses are coincident, warranting further investigation of this relationship. Comparisons between active and scarring trachoma supported the relative absence of type-2 interferon responses in scarring, whilst highlighting a common suppression of re-epithelialization with altered epithelial and bacterial adhesion, likely contributing to development of scarring pathology.

Title: Patient Adherence to Immunosuppressive Therapy for Chronic Inflammatory Eye Disease., Purpose: To investigate adherence rates to immunosuppressive therapy (IMT) for treatment of noninfectious inflammatory eye disease (IED), adherence and disease control, and factors associated with nonadherence., Method: Retrospective review of medical charts from 2015 to 2020 was conducted on patients with IED at 6 months, 1 and 2 years after initiation of IMT., Results: Of 183 patients, adherence rates at 6 months and 1 year were 70% and 58% by 2 years. Eighty-two percent, 78%, and 65% of patients with disease quiescence were adherent at 6 months, 1 and 2 years, respectively. Adherent patients have 1.86 (95% CI 1.09, 3.20) times greater likelihood for disease control compared to nonadherent. Primary reason for nonadherence was patient self-discontinuation. No specific factors were associated with nonadherence., Conclusion: Patients on IMT for IED had steady adherence rates up to 1 year, with decreased adherence at 2 years. Adherence to IMT significantly correlates with disease quiescence.

'iSupport' is an online psychoeducation and skills development intervention created by the World Health Organisation to support people with dementia. This project adapted iSupport for carers of people with rare dementias (iSupport RDC), creating a new resource to support the health and wellbeing of this underserved population. The adaptation involved three phases: (1) Co-design methods to generate preliminary adaptations; (2) Analysis of phase one findings informing adaptations to iSupport to develop; iSupport RDC; (3) Post-adaptation survey to ascertain participant agreement with the adaptations in iSupport RDC. Fourteen participants contributed, resulting in 212 suggested adaptations, of which 94 (92%) were considered practical, generalisable, and aligned with iSupport principles. These adaptations encompassed content and design changes, including addressing the challenges of rare dementias (PCA, PPA, LBD, and FTD). iSupport RDC represents a significant adaptation of the WHO iSupport intervention. Its tailored nature acknowledges the unique needs of people caring for someone with a rare dementia, improving their access to specialised resources and support. By extending iSupport to this population, it contributes to advancing dementia care inclusivity and broadening the understanding of rare dementias. A feasibility study is underway to assess iSupport RDCs acceptability, with prospects for cultural adaptations to benefit carers globally.

Objective: Rare disease Background: Encephalocraniocutaneous lipomatosis is a rare neurocutaneous disorder characterized by cutaneous, ocular, and central nervous system anomalies; its molecular etiology was recently identified. This report describes the surgical treatment and genetic characterization of a giant ocular lipodermoid cyst secondary to encephalocraniocutaneous lipomatosis. Case Report: An 11-year-old girl with past medical history of absence seizures presented with a reddish protruding mass in her right eye involving the temporal conjunctiva and the peripheral temporal cornea; eyelid closure was not possible due to mass protrusion. She also presented skin tags at the level of the external canthus and 3 alopecic areas at the level of the scalp compatible with nevus psiloliparus. No family history was reported. A dermoid cyst was suspected and excisional biopsy was performed under general anesthesia. A large conjunctival and lamellar corneoscleral resection was done, followed by a corneal tectonic graft. Molecular analysis was carried out, including PCR and Sanger sequencing on DNA obtained from the mass. After surgery, the patient achieved complete eyelid closure, reduction of ocular surface symptoms, and improved aesthetic appearance. Histological analysis confirmed a lipodermoid cyst; genetic tests confirmed a mosaic activating mutation in FGFR1 (c.1638C>A, p.Asn546Lys). The diagnosis was encephalocraniocutaneous lipomatosis. Conclusions: ECCL is a rare condition; an accurate diagnosis comprising clinical and genetic aspects can facilitate the monitoring of possible complications, improve the multidisciplinary treatment, and provide valuable information for future therapy developments. In this case, the patient’s quality of life improved significantly, ocular symptoms disappeared, and a good esthetic appearance was achieved. [ABSTRACT FROM AUTHOR]

Graft-versus-host Disease (GVHD) is a major complication with high morbidity and mortality rates on patients undergoing hematopoietic stem cell transplantation. The ocular involvement, named ocular GVHD, may affect all structures of the eyes, but the lacrimal unit (lacrimal glands and ocular surface) is the main target of the inflammatory response mediated by the donor T cells. The development of dry eye disease is the main clinical ocular manifestation, and the association of a variety of therapeutics options is necessary. The aim of the review is to describe the clinical manifestations, diagnostic criteria, impact in quality of life, the current treatment and future perspectives of this disease that demands a multidisciplinary follow-up.
