A woman in her 40s with an unremarkable medical history presented with bilateral blurred vision. Visual acuity was 20/40 OU. Slitlamp examination revealed bilateral peripheral corneal fibrosis and nasal superficial vascularization resembling a pseudopterygium. Corneal topography identified irregular astigmatism (5.9 diopters [D] OD; 7.7 D OS), and optical coherence tomography showed focal hyperreflectivity as well as subepithelial nodules (Figure, A).
