Ravi Sharma, Sandeep Randhawa
A 12-year-old Indian boy presented with acute and severe vision loss in his right eye. He was being treated for scalp alopecia areata and rashes behind the ears and above the brow. The eye examination revealed unilateral hemorrhagic retinal vasculitis. The lab work was normal except for a positive HLA-B27 result. The patient was treated with intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) and systemic immunosuppression. The retinal vasculitis improved with treatment, but visual acuity only mildly improved...

Persistent placoid maculopathy (PPM) is a rare clinical entity that has previously been reported in the literature with a characteristic appearance on multimodal imaging, including hypofluorescence observed on fluorescein angiogram (FA) and indocyanine green angiography (ICGA). The leading mechanisms proposed for this hypofluorescence include impaired choroidal vasculature with nonperfusion of the choriocapillaris and/or blockage of choroidal fluorescence by inflammatory deposits. This report demonstrates previously unreported characteristics of chorioretinal perfusion in a case of acute onset PPM in a 58-year-old woman...

A 62-year-old female who was legally blind secondary to retinitis pigmentosa (RP) developed new positive visual phenomena (PVP) ("visual storms") following implantation of the Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA). The potential mechanisms for the exacerbating PVP or hallucinatory release phenomena are proposed. Clinicians should be aware of these visual phenomena in patients with RP and the potential for worsening of or de novo development of PVP in patients considering the Argus II implant...

The authors report the first case, to their knowledge, of failed pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD) repair in a patient with ocular albinism (OA). The failure of PR to spontaneously resolve the subretinal fluid and reattach the retina in this case is suggestive of a deficiency in subretinal fluid reabsorption by the retinal pigment epithelium (RPE). These findings suggest that in cases of RRD in OA, primary PR should be avoided since this procedure relies on an adequately functioning RPE pump to reabsorb subretinal fluid prior to laser retinopexy...

This case involved a 75-year-old female with left-eye epiretinal membrane (ERM) and cataract who developed serious eye disorders during vitreous surgery due to methylrosaniline chloride (MRC) being mistakenly injected and applied to the retina instead of Brilliant Blue G during internal limiting membrane staining. Once realized, MRC was washed out with intraocular infusion solution, and ERM surgery was successfully completed. Postoperatively, a Descemet's fold and corneal edema, marked reduction in corneal endothelial cell density, and inner retina damage and visual field defect extending from the macula toward the temporal side were observed...
