Abstract

Objective: In this study our main goal is to evaluate the outcome of YAG laser PI (peripheral iridotomy) in management of glaucoma patients in Bangladesh.

Method: This cross-sectional study was done in the in the National Institute of Ophthalmology & Hospital from September 2013 to September 2016. A total of 120 consecutive patients were included. On the basis of Academy of Ophthalmology primary Angle Closure glaucoma preferred practice pattern patients were sub divided into three group: primary angle closure suspect (PACS) (#180° iridotrabecular contact [ITC], normal IOP and no optic nerve damage), n=40:  primary angle closure (PAC) ($180° ITC with peripheral anterior synechiae [PAS] or elevated IOP, but no optic neuropathy), n=40; and primary angle closure glaucoma (PACG) ($180° ITC with PAS, elevated IOP and optic neuropathy, n=40.

Results: during the study, 40% percent of the patients had undergone bilateral LPI. mean power used in primary angle closure glaucoma was 130±126.8.3% produced hyphema in 1st year, followed by 1% produced hyphema in 2nd year, no patients found in 3rd year. In primary angle closure suspect cases, 27% had repeated laser peripheral iridotomy, followed 11% in primary angle closure cases and 15% in primary angle closure glaucoma

Conclusion: From our study we can conclude that, laser iridotomy for the clinical treatment of early primary angle-closure glaucoma effectively reduces the intraocular pressure and improves the acuity level of patient. Early treatment by laser iridotomy may also reduce the risk rate to develop primary angle glaucoma. The effective rate of treatment is high, so the treatment improves the quality of life of patients.
