The Role of Prophylactic Laser Iridotomy on the Fellow Eye in Primary Angle Closure Glaucoma, MOHAMAD S. SAAD
Abstract
Purpose: To evaluate the long-term efficacy of laser peripheral iridotomy (LPI) of fellow eye of patients with acute primary angle-closure glaucoma (APACG).
Design: Retrospective non comparative case series.
Material and Methods: Forty six patients (46 eyes) with APACG at presentation to Assiut University Hospital from January, 2005 to December 2008 were included. All fellow eyes were initially treated with prophylactic pilocarpine 2% eye drops four times daily before LPI which was done within 2 weeks. All patients were followed to detect development of acute angle-closure and rise of IOP.
Results: No cases developed APAC after LPI during the follow-up of 37.3±7.1 months. Thirty eight eyes (82.8%) did not develop rise of IOP during the follow-up period, while the remaining eight eyes (17.2%) developed chronic rise of IOP and required additional treatment.
Conclusion: LPI is effective in preventing angle-closure in fellow eyes. Long-term follow-up is recommended to detect any rise of IOP that may occur and required additional treat-ment.
