Pellucid Marginal Degeneration

Pellucid marginal degeneration is a rare disorder of the cornea in which it thins in its lower part, taking on an irregular shape that alters the way the eye focuses images. It is usually bilateral and progresses slowly.

How it presents: blurry or distorted vision, astigmatism that changes over time, and difficulty achieving a stable correction with glasses.

When is a checkup advisable? When the vision prescription changes frequently or vision becomes distorted despite the use of lenses, a detailed study of the cornea is worthwhile.

Who evaluates it? The ophthalmologist makes the diagnosis through specialized studies, and the optometrist assists in following up on the vision correction. If you notice persistent vision changes, a professional checkup allows the appropriate follow-up to be defined.
