Abstract

Purpose: To describe the previously unreported concomitance of 2 uncommon ocular conditions: posterior polymorphous corneal dystrophy (PPCD) and large colloid drusen (LCD). Methods: A 45-year-old woman underwent a complete ophthalmologic examination with slit-lamp biomicroscopy and blue fundus autofluorescence with spectral-domain optical coherence tomography, as well as complete systemic examination and renal function investigation. Results: On slit-lamp biomicroscopy, a corneal lesion located at Descemet membrane was observed in the right eye. The clinical features of deep posterior stromal-endothelial linear bands with vesicles and irregular opacities of posterior corneal surface were consistent with the diagnosis of PPCD. Fundus biomicroscopy and blue fundus autofluorescence showed LCD. Discussions: We report the unusual coexistence of PPCD and LCD in a young, healthy subject. Posterior polymorphous corneal dystrophy and LCD share morphologic similarities and dysfunctions of collagen architecture in the basement membrane layer, which suggests a possible common pathogenic pathway.
