REVIEW CLINICAL CHARACTERISTICS AND TREATMENT OUTCOME OF PRIMARY ANGLE CLOSURE GLAUCOMA BY USED ND: YAG LASER PERIPHERAL IRIDOTOMY

Abstract

Objectives: To review the clinical characteristics of primary angle closure glaucoma and the outcome of Nd: YAG laser peripheral iridoctom. Materials and Methods: Prospective study of 46 eyes underwent iridotomy, evaluation of the intraocular pressure and the anterior chamber angle within 2 weeks, 1 month, 3 months & 6 months after treatment. Results: The majority of subjects were females 73.33%, over 60 years of age (80%), blurred vision and decrease visual acuity when the patient were hospitalized (43.48%), 19.65% eye pain, physical symptoms are mainly shallow anterior chamber or pupillary reflexes relaxing lazy. Embryonic glaucoma and chronic angle glaucoma distribution percentage 69.57%. Mean IOP after 2 weeks X = 18.17 ± 1.37 mmHg, 7.66 mmHg lower than before treatment. Anterior chamber angle width increased significantly after 2 weeks of treatment. And no significant changer after 1 month, 3 months & 6 months. There was a precise inverse relation between anterior chamber angle width before treatment with low levels of IOP after treatment, and there was a precise proportional relation between the low levels of IOP with the increase of chamber angle width after treatment. Conclusion: Nd: YAG laser iridotomy is effective in widening the anterior chamber angle and lowering intraocular pressure in primary angle closure glaucoma.
