Peripheral Exudative Hemorrhagic Chorioretinopathy (PEHCR): Diagnostic and Therapeutic Challenges.

Background and Objectives: Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a peripheral retinal vascular abnormality that is likely underreported. We review the differential diagnoses, etiology, and treatment options for PEHCR. Methods: We present a case of an asymptomatic 72-year-old female referred following left eye fundus photography finding of the peripheral lesion. Results: Fundus photography demonstrated a large temporal pigment epithelial detachment (PED) with adjacent fibrovascular membrane. Optical coherence tomography (OCT) confirmed the PED with trace subretinal fluid. Fluorescein angiography (FA) demonstrated early and late hypofluorescence of the PED with late leakage of the adjacent temporal fibrovascular membrane. Observation was elected, visual acuity remained unaffected, and the PED spontaneously resolved. Conclusions: Due to the peripheral location, patients often present as asymptomatic; however, vision loss can occur due to vitreous hemorrhage or extension of subretinal fluid, hemorrhage, or exudate to the macula. Commonly, these lesions are referred with concern for choroidal melanoma due to their large, dark, elevated presentation in the peripheral retina. Multimodal testing using B-scan, FA, and OCT is important in establishing the proper diagnosis. PEHCR lesions can often be observed without treatment, though intravitreal injection of anti-VEGF is increasingly used to prevent secondary causes of vision loss.

NONSURGICAL RESOLUTION OF FULL-THICKNESS MACULAR HOLES WITHOUT VITREOMACULAR TRACTION.

BACKGROUND/PURPOSE: The purpose of this study was to report a case series of full-thickness macular holes without vitreomacular traction that resolved without surgery. METHODS: This study is a retrospective case series of 11 patients who demonstrated closure of full-thickness macular holes without surgical intervention. RESULTS: All full-thickness macular holes closed, with all patients having improvement in visual acuity. All but one of the cases had visual acuity better than 20/40 at last recorded visit. Most cases presented with associated epiretinal membrane (73%), cystoid changes (64%), defects <150 µ m (80%), and resolved within 2 months (91%). Topical anti-inflammatory drops were used in 7 of 11 cases, and dorzolamide was used in one case. CONCLUSION: Full-thickness macular holes can develop in eyes without the presence of vitreomacular traction. Topical therapy without vitrectomy may be particularly helpful in closure of full-thickness macular holes with associated cystoid macular edema. Holes with a lamellar hole component may spontaneously resolve as part of a retinal remodeling process.

Uveitis reactivation following recombinant zoster vaccination.

PURPOSE: Describe three cases of uveitis reactivation following immunization with recombinant zoster vaccine (RZV). OBSERVATIONS: One patient developed reactivation of previously controlled multifocal choroiditis within one week of receiving RZV, requiring treatment with systemic corticosteroids. Two patients with previously controlled anterior uveitis developed new anterior segment inflammation after RZV; both were treated with topical corticosteroids and systemic antiviral therapy. CONCLUSION AND IMPORTANCE: Uveitis recurrence is an infrequent but serious potential ocular side effect of recombinant zoster vaccination.
