# Bilateral Persistent Pupillary Membrane

## TL;DR

A 31-year-old man with bilateral persistent pupillary membranes was found to have no vision impairment due to a spared central pupil area.

## Contribution

This case highlights that extensive PPMs may not require surgery if the visual axis is unobstructed and the patient is beyond the amblyogenic period.

## Key findings

- Bilateral PPMs were present but did not impair vision due to a 1.5 mm central pupil zone remaining clear.
- The patient's age and unobstructed visual axis supported a non-interventional management approach.
- PPMs were confirmed to be asymptomatic and not affecting visual development.

## Abstract

A 31‐year‐old man presented for a routine eye exam with bilateral asymptomatic persistent pupillary membranes, with the central 1.5 mm zone of the pupil spared, preventing vision impairment.

Persistent pupillary membranes (PPMs) are common congenital remnants that typically do not interfere with visual development and rarely lead to amblyopia. Consequently, surgical intervention is seldom required. In this case, despite extensive bilateral PPMs, the spared visual axis and the patient's age beyond the amblyogenic period justified an observation‐only approach.
