A 15-year-old boy presented with decreased vision in both eyes, and a slit lamp examination revealed this finding. What is the diagnosis?
Correct Answer: Persistent hyperplastic primary vitreous
Description: Answer B. Persistent pupillary membranesThe correct answer is persistent pupillary membranes (PPMs). PPMs represent remnants of the tunica vasculosa lentis, which is the blood supply for the developing lens of the fetus. Remnants of the capillaries may persist as small strands attached to the collarette of the iris. Vision is usually unaffected, but occasionally thick, persistent pupillary membranes can cause deprivational amblyopia.
