Definition

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. [from HPO]

Disease or Syndrome
Groenouw type I, or granular type I, corneal dystrophy (CDGG1) is an autosomal dominant disorder characterized by irregular aggregates of hyaline material in the corneal stroma. These aggregates can cause significant visual disturbance and may require corneal transplantation for restoration of visual acuity or for relief from recurrent corneal erosions (summary by Stone et al., 1994).
