Abstract

Purpose: The aim of this study was to evaluate the anterior segment swept source optical coherence tomography (SS-OCT) and in vivo confocal microscopy (IVCM) features in a patient with bleb-like epithelial basement membrane dystrophy (EBMD). Methods: A 67-year-old man was referred to the hospital for recurrent attacks of severe ocular pain, tearing, and photophobia, typically upon awakening in the right eye. Biomicroscopic examination revealed pebbled glass-like appearance in the corneal epithelium which was remarkable with retroillumination and the patient was suspected to have bleb-like EBMD. The cornea was further evaluated using SS-OCT DRI Triton (Topcon, Tokyo, Japan) and IVCM (Heidelberg Retina Tomograph 3, Rostock Cornea Module). Results: Using anterior segment SS-OCT, multiple, hyporeflective, round-oval structures within the size range of 30 to 90 μm were observed at the basal epithelial level. IVCM showed circular or oval hyporeflective areas with a diameter ranging from 30 to 140 μm at the level of the basal epithelium in a depth of 35 to 40 μm from the corneal surface and hyperreflective linear structures extending into the corneal epithelium. The corneal stroma was normal, while a few round hyperreflective deposits and guttae were noted at the endothelial cell layer. Conclusions: Anterior segment SS-OCT and IVCM can be used in the diagnosis of bleb-like EBMD and are very helpful in differentiating from other epithelial/subepithelial corneal dystrophies and cystic disorders of the corneal epithelium.
