Granular corneal dystrophy

What it means

The presence of central, fine, whitish granular lesions in the stroma of the cornea. This type of corneal dystrophy is usually asymptomatic and begins in childhood and shows a slow progression. Later in the course, the corneal epithelium and Bowman's layer may be affected. Histologically, the cornea shows a uniform deposition of hyaline material.
