Title	Persistent Pupillary Membrane Variants: Case of an Adult Patient with Anterior Capsular Plaque

Purpose	Persistent pupillary membrane (PPM) is a frequent neonatal finding, usually regressing spontaneously. We report an atypical case of PPM with wide strands associated with an anterior capsular plaque (ACP) in an adult.
Methods	A 22-year-old Caucasian man with no ocular complaints presented for routine examination. Medical history included lymphoma treated by allogeneic bone marrow transplant, without congenital anomalies. Visual acuity was 10/10 OU, with no amblyopia. Slit-lamp evaluation showed clear corneas, normal anterior chambers, and absence of synechiae. In the left eye, a PPM with multiple strands bridged the iris collarette to the lens (Duke-Elder type II). The lenticular attachment ended in a white opaque anterior plaque. Fundus was normal.
Results	PPM originates from remnants of the anterior tunica vasculosa lentis, supplying the lens in utero, and usually regresses by the third trimester. In this asymptomatic case with preserved visual axis, a conservative approach with periodic monitoring was adopted. ACPs associated with iridolenticular PPM have been reported, and may be indistinguishable preoperatively from anterior polar cataracts. Accurate differentiation is crucial if surgery is needed to prevent unnecessary lens extraction.
Conclusion	This case highlights an uncommon adult presentation of PPM associated with ACP. Although PPM is often benign, atypical variants may mimic anterior polar cataracts and pose diagnostic challenges. Recognition of such forms contributes to a better understanding of the spectrum of PPM and aids surgical decision-making.
