Abstract
PurposeTo report the findings of anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM) in two patients with peripheral hypertrophic subepithelial corneal degeneration (PHSD).MethodsCase series by restrospective chart review and imaging analysis of AS-OCT and IVCM.ResultsSlit lamp examination of the two patients revealed a bilateral subepithelial-elevated fibrous tissue of the superior-nasal quadrant, as well as inferior-nasal in one of the patients. Best corrected visual acuity ranged from 20/25 to 20/15. AS-OCT showed continuous, homogenous, well-demarked hyperreflective subepithelial band associated with hyperreflectivity in the anterior stroma. IVCM demonstrated normal epithelial cell morphology and arrangement and a fibrous structure subepithelial and in the anterior stroma.ConclusionAS-OCT and IVCM can facilitate the diagnosis of PHSD and differentiate it from other corneal entities that present peripheral opacifications.
