# What is granular dystrophy?

Granular corneal dystrophy is an inherited condition where tiny opaque deposits build up in the corneal stroma. These white spots can gradually merge and reduce clarity.

## Symptoms

Many people are asymptomatic in early life and are diagnosed during routine examination. Later, blurred vision, glare, and recurrent erosions can occur as deposits increase.

- Usually bilateral and symmetrical
- May worsen after refractive surgery in some genetic variants
- Family members may also be affected

## Treatment

Mild disease is managed with lubrication and monitoring. In more advanced stages, phototherapeutic keratectomy or corneal transplantation may be needed, typically arranged via general ophthalmology services.
