AIMS: To evaluate the efficacy of diode laser trabeculoplasty (DLT) and frequency doubled Nd : YAG laser trabeculoplasty (YLT) in primary open angle glaucoma (POAG). METHODS: A total of 52 eyes of 35 patients with POAG were included. In all, 25 eyes underwent DLT (Group I) and 27 eyes underwent YLT (Group II). IOP, gonioscopy and visual fields were evaluated before and 3, 6, and 9 months and 1 year after the laser. An IOP < 21 mmHg without medications or a decrease in the number of glaucoma medications with no progression of disc and field changes was considered a success. RESULTS: The mean age of patients in Group I was 57.72 ± 8.1 years and the patients in Group II had a mean age of 59.85 ± 7.76 years. The mean prelaser IOP was 24.93 ± 1.49 mmHg and 25.36 ± 1.57 mmHg. The mean IOP after DLT at 12 months follow-up was 18.0 ± 0.93 mmHg and after YLT was 18.6 ± 1.52 mmHg. The reduction of IOP was statistically significant in both the groups at 3, 6, 9, and 12 months (P < 0.001), however there was no significant difference between the two groups. Success rates in both groups were similar, 92% in Group I and 92.6% in Group II. CONCLUSIONS: DLT and Fd YLT are equally effective in controlling IOP in eyes with POAG.Eye (2006) 20, 1352-1356. doi:10.1038/sj.eye.6702108; published online 7 October 2005.
