A 54-year-old Japanese woman presented with bilateral blurring of vision associated with headache that had started 2 weeks earlier. Her general family medical history and her personal medical history, including her history of ocular disease, were unremarkable. The best-corrected visual acuity on presentation was 0.6 in the right eye and 0.1 in the left eye. The intraocular pressure was normal in both eyes. Slit-lamp biomicroscopy showed bilateral anterior chamber cells and posterior synechiae, and fundus examination showed bilateral disc swelling with exudative retinal detachment (fig. ).\nFluorescein angiography detected bilateral multifocal leakage with pooling of dye in the subretinal space in the late phase (fig. ). Indocyanine green angiography showed patches of hyperfluorescence and hypofluorescent spots bilaterally (fig. ). A spectral-domain OCT (Cirrus HD-OCT 4000; Carl Zeiss Meditec Inc.) image of the eyes showed the bilateral presence of subretinal fluid and pigment epithelial detachment. Moreover, only in the left eye was unilateral choroidal excavation detected under the fovea, and the contour of the retinal pigment epithelium appeared to be conforming to the shape of the fibrin (fig. ).\nSystemic workup revealed positive HLA-DR4 as well as cerebrospinal fluid pleocytosis. A diagnosis of VKH was reached soon afterwards. Thus, our patient was treated with intravenous pulse methylprednisolone followed by oral prednisolone (initial dose of 40 mg/day) with tapering over a course of 6 months. Treatment successfully resolved the VKH symptoms, and serial OCT showed a gradual reduction in size and a subsequent disappearance of the subretinal fibrin and fluid (fig. ). However, 1 month after having started treatment, the eye was left with an area of choroidal excavation at the fovea despite a normal contour in the right eye (fig. ). There was a good recovery of visual acuity, with 1.2 and 0.9 in the right and the left eye, respectively. Presently, the patient is being followed-up without complications and medications.
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.
