What is persistent pupilary membrane?

Persistent pupillary membrane (PPM) is a congenital condition that affects the eye's pupil and iris. PPM is caused by remnants of fetal tissue that fail to dissolve properly during prenatal development. These remnants can appear as strands or webs that stretch across the pupil or connect the iris to other structures in the eye.

In most cases, persistent pupillary membrane does not cause any significant vision problems, and many people who have it may not even be aware of its presence. However, in some cases, PPM can cause visual disturbances such as blurred or double vision, glare sensitivity, and reduced visual acuity.

Treatment for PPM typically involves monitoring the condition and addressing any visual disturbances or complications that may arise. In severe cases, surgical intervention may be necessary to remove the membrane or correct any issues with the iris or other structures in the eye. Most people with PPM have a good prognosis and can enjoy normal vision and eye function with appropriate care and management.
