Primary angle closure glaucoma causes elevation of intra ocular pressure (IOP) due to obstruction to aqueous outflow by partial or complete closure of angle by iris. Apart from medical management with topical drugs and filtration surgery, laser iridotomy is an effective primary treatment option in cases with primary angle closure. The present study was carried out in 81 patients presented with PACS, PAC and PACG who had Nd YAG laser iridotomy averaging 20 mj spread over 6 shots and also as prophylaxis in fellow eyes of patients with PACS and PAC. 93% of the patients with PAC and 71% of the patients with PACS had good control of IOP and none developed glaucomatous optic neuropathy. The complications were minimal and managed with medical treatment. Nd YAG laser iridotomy is safe and minimally invasive procedure with least complications in our experience and follow up observations included uniformly good control of IOP and stable visual fields.
