BACKGROUND AND OBJECTIVES: To explore the incidence of adverse events after bilateral same-day intravitreal 0.7-mg dexamethasone implant (SDIDI) injections. MATERIALS AND METHODS: We performed an IRB approved, single-center, retrospective review of patients receiving bilateral SDIDI injections from January 1, 2016 to October 31, 2021 and reviewed adverse events that occurred within 3 months of injection. RESULTS: A total of 206 bilateral (412 eyes) SDIDI injections were performed in 59 patients. Ocular hypertension or the addition of intraocular pressure (IOP) lowering drops occurred in 121 (29.4%) eyes after IDI. Two (0.5%) eyes required glaucoma drainage surgeries. Of the 117 phakic eyes, 32 (27.4%) had progression of cataract or cataract extraction. There were two (0.5%) episodes of vitreous hemorrhage and one (0.2%) retinal tear with retinal detachment. There were no cases of endophthalmitis. CONCLUSION: Serious complication rates after bilateral same-day IDI injections appears low. Increased IOP that requires intervention can occur.

Purpose: To identify the temporal relationship and clinical characteristics of epiretinal membrane (ERM) and macular edema (ME) formation in uveitic eyes.Methods: A total of 269 subjects (444 uveitic eyes) met study inclusion criteria. Comprehensive ophthalmic examination, spectral domain-optical coherence tomography (SD-OCT), and clinical testing were carried out.Results: Of the 444 uveitic eyes, 229 eyes (51.6%) developed an ERM, whereas 87 eyes (19.1%) developed ME. The odds ratios (ORs) of systemic disease causing uveitis and resulting in ERM and ME were significantly higher in posterior uveitis (OR 6.56, 95% CI 2.98-14.46; p < .0001) and panuveitis (OR 10.09, 95% CI 4.05-25.15; p < .0001). Temporal analysis revealed that an ERM was noted concurrently or prior to ME development in 93.8% of eyes.Conclusions: ERM and ME are primarily observed in posterior uveitis and panuveitis associated with systemic diseases. The temporal relationship highlights the importance of characterization of ERM as it relates to the development of uveitic ME.

In this retrospective, multicenter study of 261 eyes (259 patients), patients who underwent rhegmatogenous retinal detachment repair during the coronavirus disease 2019 (COVID-19) post-lockdown period experienced an additional 22-day delay, leading to significantly more epiretinal membrane and proliferative vitreoretinopathy and lower single-surgery anatomic success rates. During lockdown, perfluoropropane gas was used more commonly, and pneumatic retinopexy was used more commonly in COVID-19-positive patients.

Purpose: To report four cases of uveitis after treatment with dupilumab for atopic dermatitis.Methods: Retrospective case series.Results: Data was collected from four patients with inflammation that developed after treatment with dupilumab. The first patient was thought to have developed posterior scleritis or Harada's-type disease related to her treatment with dupilumab, with recurrence of intraocular inflammation upon restarting treatment. The second patient developed anterior and intermediate uveitis as well as cystoid macular edema in her right eye about two years after starting dupilumab treatment. The third patient developed a distinct relentless placoid chorioretinitis while on therapy with dupilumab. The fourth patient developed bilateral cystoid macular edema while on treatment with dupilumab.Conclusion: We report a case series of patients treated with dupilumab who developed intraocular manifestations of inflammatory disease.

Purpose of review: To review recent literature pertaining to sickle cell retinopathy (SCR) and, in particular, sickle cell maculopathy. Recent findings: Several recent studies suggest that macular perfusion abnormalities seen in patients with sickle cell disease of various genotypes may affect both the superficial and deep capillary plexi, with a predilection for the deep capillary plexus. Further, these changes may be associated with areas of macular thinning, as well as with peripheral retinal ischemia, even in individuals without visual symptoms, contrary to what has previously been described in both diabetic retinopathy and retinal vein occlusion. Several cases also suggest that paracentral acute middle maculopathy may be the pathophysiologic mechanism by which microvascular occlusion leads to macular thinning. Summary: Sickle cell disease can manifest in a number of ways within the orbit as well as intraocularly because of its nonspecific vasoocclusive episodes. However, SCR is the most common ophthalmic manifestation of this disease. Historically, SCR has been considered a peripheral retinopathy, but the development and use of spectral-domain optical coherence tomography and optical coherence tomography angiography suggest that significant macular vascular changes occur early in this disease, even in asymptomatic individuals.

Intraocular lymphoma is a known ocular masquerade syndrome due to its variable presentation that can simulate other forms of ocular inflammation. Ocular lymphomas, in general, are rare and diverse and are often confused with other diagnoses first. These include primary intraocular lymphoma or vitreoretinal lymphoma, which is a high-grade malignancy associated with primary CNS lymphoma, but also the more indolent uveal lymphoma and ocular adnexal lymphoma. The diagnosis of the disease is often difficult, as investigations and treatment for possible other causes of uveitis, retinitis, and generalized ocular inflammation are initially undertaken, prior to a diagnosis of lymphoma being entertained. Imaging findings in this disease can equally be very variable; however there are some general principles which may help guide the clinician to the correct diagnosis; these will be discussed in this chapter.

Major depressive disorder (MDD) is a leading cause of disability worldwide, yet current treatment strategies remain limited in their mechanistic diversity. Recent evidence has highlighted a promising novel pharmaceutical target-the KCNQ-type potassium channel-for the treatment of depressive disorders, which may exert a therapeutic effect via functional changes within the brain reward system, including the ventral striatum. The current study assessed the effects of the KCNQ channel opener ezogabine (also known as retigabine) on reward circuitry and clinical symptoms in patients with MDD. Eighteen medication-free individuals with MDD currently in a major depressive episode were enrolled in an open-label study and received ezogabine up to 900 mg/day orally over the course of 10 weeks. Resting-state functional magnetic resonance imaging data were collected at baseline and posttreatment to examine brain reward circuitry. Reward learning was measured using a computerized probabilistic reward task. After treatment with ezogabine, subjects exhibited a significant reduction of depressive symptoms (Montgomery-Asberg Depression Rating Scale score change: -13.7 ± 9.7, p

Purpose: To report a case of an immunocompetent 64-year-old man who developed cytomegalovirus (CMV) retinitis after using topical difluprednate. Observations: A 64-year-old man with type 2 diabetes developed hemorrhagic retinitis while using topical difluprednate after penetrating keratoplasty. Polymerase chain reaction of the vitreous was positive for CMV DNA. Complete blood count was within normal limits and 4th generation human immunodeficiency virus assay was negative. The retinitis resolved with oral valgancyclovir and intravitreal foscarnet injections. Conclusion and importance: CMV retinitis may occur after topical difluprednate in an immunocompetent patient.

To evaluate the use of selective vs. non-selective cyclo-oxygenase inhibitors (COXIs) for the treatment of chronic non-infectious, non-necrotizing scleritis and episcleritis.Sixty-nine patients with scleritis and episcleritis treated for ≥2 months with COXIs were included. Outcome measures were rates of inflammation control, corticosteroid sparing, and COXI discontinuation, as well as side effects.Initial inflammation control was achieved in 78-81% of scleritis patients and 73-80% episcleritis patients on COXIs (p.05). Rates of steroid sparing after 4-24 months of consecutive treatment were similar. Gastrointestinal side effects were observed in 1 (2.7%) patient on selective vs. 3 (9.4%) patients on non-selective COXIs (p = .33). Overall discontinuation rate was 6/37 (16%) for selective vs. 7/32 (22%) for non-selective COXIs (p = .76).Selective vs. non-selective COXIs were equally efficacious for the treatment of chronic non-infectious, non-necrotizing scleritis and episcleritis. Prospective studies to elucidate potential differences in side effect profiles may be warranted.

Purpose To report the clinical use of ProKera (Bio-Tissue, Inc., Miami, FL) under topical anesthesia in an outpatient for the management of ocular manifestations of acute Stevens-Johnson syndrome (SJS). Methods Interventional case report. Results A 19-year-old woman developed acute SJS with ocular involvement after ingestion of oral antibiotics. Slit-lamp examination performed 2 weeks later showed severe inflammation and areas of ulceration along all 4 lids and complete, bilateral sloughing of bulbar and palpebral conjunctivae, including the limbus. ProKera was placed under topical anesthesia without sedation in both eyes instead of an amniotic membrane due to excess risk of general anesthesia. Three weeks after placement, slit-lamp examination showed complete re-epithelialization of both corneas and conjunctivae, with only trace conjunctival injection and minor limbal epithelial irregularities. Three months postprocedure, there were no signs of clinically significant scarring, and the visual acuity (VA) was 20/20 bilaterally. Fourteen months postprocedure, VA remained stable, and the patient did not have dry eye, photophobia, clinically significant scarring, or symblepharon. Conclusions ProKera placement performed under topical anesthesia may be appropriate for the treatment of ocular surface manifestations of acute SJS particularly in those patients followed in an outpatient setting with milder forms of disease and/or with contraindications to general anesthesia.
