Isolated corneal intraepithelial neoplasia.

OBJECTIVES: To report two cases of isolated corneal intraepithelial neoplasia. MATERIAL AND METHOD: The present study included 2 cases presenting with isolated corneal intraepithelial neoplasia. Both patients were treated by corneal epithelial scraping. RESULTS: The authors present the clinical picture and histopathological findings of 2 patients suffering from corneal intraepithelial neoplasia that did not arise from the corneoscleral limbus. Both patients showed no recurrence after treatment for a period of time. CONCLUSION: Isolated corneal intraepithelial neoplasia is rare. Corneal scraping may be an effective treatment.

The results of amniotic membrane transplantation for symptomatic bullous keratopathy.

OBJECTIVES: To evaluate the outcomes of amniotic membrane transplantation for symptomatic relief in patients with bullous keratopathy. MATERIAL AND METHOD: This retrospective study included 17 eyes (17 patients) with bullous keratopathy presenting with intractable pain or discomfort. The patients were enrolled from January 2000 to December 2004. Amniotic membrane transplantation was performed. Symptomatic relief epithelial healing, and visual changes were analyzed. RESULTS: During the follow up period of 14.1 +/- 11.9 months (range 1-36 months) after amniotic membrane transplantation, 14 eyes of 17 eyes (82.4%) with intolerable pain preoperatively had pain relief postoperatively. Corneal epithelial healing was complete in all except 2 eyes one of which had evisceration because of severe corneal ulcer, and the other underwent penetrating keratoplasty soon after amniotic membrane transplantation. CONCLUSION: Amniotic membrane transplantation is a safe and effective treatment modality for pain relief associated with chronic bullous keratopathy. It can be an alternative to conjunctival flap, with better cosmetic appearance for the management of patients with bullous keratopathy.
