Unilateral acute posterior multifocal placoid pigment epitheliopathy in a convalescent COVID-19 patient.

BACKGROUND: To report a case of unilateral acute posterior multifocal placoid pigment epitheliopathy (APMPPE) in a Hispanic convalescent COVID-19 female patient. Case presentation A 35-year-old Hispanic female with exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was evaluated due to unilateral visual loss. Ophthalmic examination and diagnostic tests were consistent with APMPPE. DISCUSSION: Ocular changes can be observed in patients with COVID-19. A complete ophthalmic evaluation must be performed in patients with low vision after SARS-CoV-2 infection.

Multimodal imaging in choroidal osteoma.

PURPOSE: To describe characteristics of choroidal osteomas (CO), using ocular ultrasound, fluorescein angiography, ultra-widefield retinal imaging, ultra-widefield autofluorescence, optical coherence tomography, enhanced-depth-imaging OCT, and OCT angiography (OCT-A). METHODS: Retrospective, observational case series study. Clinical records from patients with diagnosis of CO who underwent complete imaging evaluation were analyzed. RESULTS: Sixteen eyes from 11 patients were included. Mean patient age was 33.4 years (range 20-61), 72.7% were female, 100% were Hispanic, and 54.5% had unilateral CO. Median visual acuity was 20/150 (range 20/20-2000). CO was completely calcified in 25%, partially decalcified in 50%, and decalcified in 25%. Other features included choroidal neovascularization (18.75%), focal choroidal excavation (12.5%), choroidal depression associated to decalcification (18.75%), thinning of outer retina and photoreceptor layers over decalcified tumor (75%). Decreased fluorescence on FAF was observed in decalcified regions while relatively preserved fluorescence was observed in calcified regions. CONCLUSIONS: Nowadays, diagnostic tests provide important information about each stage of choroidal osteoma. Progressive decalcification of the tumor might have a common pathogenic role for development of FCE or choroidal depression. OCT-A/FA proved to be valuable tools for detection of CNV in patients with CO.

New insights in diagnosis and treatment for Retinopathy of Prematurity.

The purpose of this study was to review current perspectives on diagnosis and treatment of Retinopathy of Prematurity (ROP). We performed a systematic review of how much has been produced in research published online and on print regarding ROP in different settings around the world. Early Treatment for ROP (ETROP) classification is the currently accepted classification of ROP. Fluorescein angiography and spectral domain optical coherence tomography (SD-OCT) may eventually lead to changes in the definition of ROP, and as a consequence, they will serve as a guide for treatment. Intravitreal anti-VEGF therapy has proven to be more effective in terms of lowering recurrence, allowing growth of the peripheral retina, and diminishing the incidence of retinal detachment when proliferative ROP is diagnosed. Whether anti-VEGF plus laser are better than any of these therapies separately remains a subject of discussion. Telemedicine is evolving everyday to allow access to remote areas that do not count with a retina specialist for treatment. A management algorithm is proposed according to our reference center experience. ROP is an evolving subject, with a vulnerable population of study that, once treated with good results, leads to a reduction in visual disability and in consequence, in a lifetime improvement.
