Abstract

PURPOSE: To report characteristics of Vogt-Koyanagi-Harada (VKH) disease as observed on spectral-domain optical coherence tomography (SD-OCT) images. CASE SUMMARY: (Case 1) A 38-year-old female presented with visual impairment in both eyes. On fundus examination, multifocal serous retinal detachment in the posterior pole was observed in both eyes. On enhanced SD-OCT, serous retinal detachment and cystoid macular edema in the outer retina were observed and the intraretinal fluid space was divided by a membranous structure forming an intraretinal compartmentalized cystic space. Under the diagnosis of VKH disease, the patient was treated with intravenous administration of methylprednisolone. After treatment, enhanced SD-OCT images showed decreased serous retinal detachment. (Case 2) A 58-year-old male presented with visual impairment in both eyes. On fundus examination, multifocal serous retinal detachment in the posterior pole was observed in both eyes. On enhanced SD-OCT, choroidal folds were observed and the membranous structure showed continuity with ellipsoid zone, suggesting the membranous structure was part of the outer photoreceptor layer of the adjacent attached retina. The patient was treated with intravenous administration of methylprednisolone. After treatment, enhanced SD-OCT images showed cystic space was decreased. CONCLUSIONS: SD-OCT images of VKH disease demonstrated multiple serous retinal detachments and intraretinal compartmentalized cystic space divided by a membranous structure. The membranous structure may be considered a part of the outer photoreceptor layer of the attached retina.
