A 55-year-old man (subject 1) presented with bilateral metamorphopsia, with decimal visual acuity being 0.8 in the right eye and 1.2 in the left. The clinical diagnosis of VKH was made based on bilateral panuveitis and multifocal exudative retinal detachments at the posterior poles (). High-dose corticosteroid therapy with gradual tapering was initiated 3 days after presentation. The serous detachments entirely resolved within 9 weeks and visual acuity in the right eye improved to 1.2.\nSerial spectral-domain OCT (SD-OCT) images obtained at the preuveitic, uveitic, and posttreatment phase are shown in . SD-OCT obtained 1 year before the onset of VKH due to symptoms of a floater and visual disturbance demonstrated a dome-shaped posterior protrusion of the RPE and outer retinal layers into the choroidal cavity (ie, conforming FCE) at the fovea in the right eye. SD-OCT at the uveitic phase identified multiple bilateral sensory retinal detachments, with the FCE now involving only the RPE (ie, nonconforming FCE). Nine weeks after the treatment, the nonconforming FCE returned into a conforming pattern.\nThe FCE pattern and its alteration during treatment of the case with VKH were compared to those of four subjects with FCE associated with other chorioretinal conditions (). This comparison group consisted of two patients with age-related macular degeneration (AMD; subjects 2 and 3), one subject with a macular hole (MH; subject 4), and one asymptomatic individual (subject 5). Treatment with intravitreal ranibizumab injections and vitrectomy had been performed in the patients with AMD and MH, respectively. A conforming FCE was observed in three patients (subjects 2, 3, and 5) and pattern alteration from nonconforming to conforming FCE was found after treatment in one subject (subject 4). In the two subjects with AMD, a hyperreflective material around the FCE was absorbed, resulting in a well-demarcated conforming FCE after treatment.
A 48-year-old female presented to us with blurring and distortion of vision in OS since 2 weeks. Her BCVA was 6/6; N6 in OD and 6/24;N10 in OS at presentation. Fundus examination showed an extrafoveal CNVM. Based on multimodal imaging including SD-OCT and FFA, patient was diagnosed to have type-2 CNVM with subfoveal choroidal thickness of 505 μm. She was also treated with antiVEGF monotherapy on pro re nata (PRN) basis and had multiple recurrences over 5 years. Interestingly, she developed FCE at the site of resolved CNVM scar, during 23 months of treatment, which progressively increased from 85 μm to 154 μm in depth over the subsequent follow-ups. We report this as a case of acquired FCE secondary to CNVM [].
