RESUMO
OBJECTIVE: To demonstrate the spectrum of autoimmune retinopathy (AIR) associated with immunotherapy for advanced cutaneous melanoma. METHODS AND ANALYSIS: Retrospective chart review on patients with advanced cutaneous melanoma who developed AIR after initiating immunotherapy. Complete ophthalmic examination and relevant ancillary testing were performed on each patient. The presence of AIR-associated anti-retinal antibodies was confirmed by western blot and/or immunohistochemical staining. Ophthalmic and systemic outcomes after treatment for AIR were followed over time. A systematic review of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Case 1 developed photopsia and nyctalopia with electroretinographic findings characteristic for melanoma-associated retinopathy 1 week after initiating ipilimumab/nivolumab immunotherapy. Case 2 experienced new severe bilateral visual field loss associated with anti-retinal and anti-optic nerve antibodies while on maintenance nivolumab immunotherapy. Case 3 developed decreased visual acuity due to acute exudative polymorphous vitelliform maculopathy within 2 weeks of initiating ipilimumab/nivolumab immunotherapy. All patients had concurrent extraocular immune-related adverse events in addition to the presence of anti-retinal antibodies on serological testing. 14 published cases of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma were identified and reviewed. CONCLUSIONS: Immune checkpoint inhibition can trigger the development of AIR with varied clinical manifestations in patients with advanced cutaneous melanoma. This study highlights the need for close monitoring in cutaneous melanoma patients receiving immunotherapy who develop new visual symptoms with or without funduscopic changes, as well as the potential role for screening of patients prior to initiating immunotherapy.

Purpose: To study the relationship between complete blood count (CBC) indices over time, particularly serum hemoglobin (Hb) levels, and severity of macular thinning on spectral domain optical coherence tomography (SD-OCT) in patients with sickle cell disease (SCD). Methods: This is a single-center, retrospective analysis of 141 consecutive SCD patients over a 10-year period, of which 40 patients (79 eyes) had SD-OCT imaging of the macula and 29 (58 eyes, mean age 17.5 years) were eligible for the study. Investigators reviewed electronic medical records for documentation of retinopathy stage, disease genotype, CBC values, and SD-OCT imaging. SD-OCT parameters and CBC values were compared between different retinopathy stages and disease genotypes. Regression analyses were performed on SD-OCT parameters and CBC values. Results: Of the 58 eligible eyes (34HbSS, 18HbSC, 4HbSß +thal, 2HbS ßthal), 18 had PSR (proliferative sickle retinopathy), 14 had NPSR (nonproliferative sickle retinopathy), and 26 had NSR (no sickle retinopathy). Hb values were higher in SC group compared to SS group. Macular thickness in the temporal inner (Δ=26±33 um, p=0.01) and outer (Δ=21±30 um, p=0.02) subfields was higher in SC compared to SS group. Patients with SD-OCT thinning below the 5th percentile in the temporal outer subfields had lower recorded Hb nadirs (6.0±0.9) compared to those with thickness within the top 95th percentile (9.1±2.3). Regression analysis showed temporal macular thickness to be positively correlated with Hb values in the SS group. Conclusion: Macular thinning observed on SD-OCT in SCD patients with SS genotype may be related to the level of anemia in this population.
RESUMO
A case of late-onset choroidal neovascularization in a patient with a history of West Nile virus chorioretinitis is described. An 86-year-old man with a history of diabetes mellitus developed bilateral West Nile virus chorioretinitis in 2001, after which his vision improved to baseline. Approximately 5 years later, the patient was found to have choroidal neovascularization in his left eye, for which he received an intravitreal injection of bevacizumab. After one injection, there was good anatomical response. Choroidal neovascularization may be a late-onset complication of West Nile virus chorioretinitis, and bevacizumab may be a good therapeutic option.

We present a case of paracentral acute middle maculopathy (PAMM) in a patient with sickle cell disease (SCD). Though gradual capillary loss may contribute to pathophysiology of sickle cell retinopathy as well, our case suggests that PAMM may be the precursor lesion to macular thinning commonly observed in patients with SCD. In addition, fluorescein angiography may be unable to detect these acute vascular events occurring at the deep capillary plexus.

A female infant born prematurely at 23 weeks' gestational age developed bilateral hereditary cataracts at post-menstrual age 33 weeks, which precluded retinopathy of prematurity screening. The infant underwent right cataract extraction 1 week later, and retinopathy of prematurity was monitored by examining the right eye. In the seventeenth week of life (post-menstrual age 40 weeks), the cataract was removed from the left eye. Visual outcome at 19 months of age was good in both eyes. Very early cataract extraction may be necessary in premature infants to allow ROP evaluations.
