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 28-year-old female patient presented with metamorphopsia in her left eye starting 2 days earlier. There was nothing of note in her medical or family history, and her visual acuity was 1.0 in the right eye and 0.8 with -5.0 D refraction in the left eye. Anterior segment examination was normal. Fundus examination was normal in the right eye, but macular pigmentary alterations were observed in the left eye (). On FFA there was hyperfluorescence beginning in the early phases and increasing in the late phase, which was more suggestive of choroidal neovascular membrane (CNVM) than CSCR (). Although it is recommended for a definitive diagnosis, ICGA was not done. Despite smooth foveal contours in the left eye on OCT, an area of subfoveal focal choroidal excavation and overlying hyporeflective subretinal fluid were detected (). The lesion in the patient’s left eye was accepted as CNVM and an intravitreal bevacizumab injection was administered. At follow-up 1 month later, the patient’s symptoms had improved, vision in her left eye improved to 0.9 and the hyporeflective area evident on OCT had decreased in size. At 2-year follow-up, visual acuity in the left eye was 0.8 and persistent RPE changes were observed on fundoscopy (). Hyperfluorescence which increased slightly in the late phases was observed on FFA of the left eye (). On OCT, the focal choroidal excavation remained unchanged, the overlying hyporeflective area had resolved and the photoreceptor layer appeared continuous ().
