| Abstract |
|
Penetrating keratoplasty was performed in six eyes of granular corneal dystrophy. Vision was improved from worse than 0.05 to better than 0.4. Mean follow-up period is 14 months (12-18 months). Corneal deposits were stained for H and E. Masson trichrome, Wilder's reticulin and Luxol fast blue but not for PAS, Congo red and Oil red a stain. Electron micorscopic examination showed that polymorphic, electron dense rod-shaped bodies were present in the Bowman's layer and between stromal lamellae and in the interceliular space of corneal epithelium. And, for the first time we found a area looked like a transformation from normal stroma to the granular deposit. |
