PURPOSE: To evaluate the efficacy of selective laser trabeculoplasty (SLT) in the adjunctive treatment of medically diagnosed open-angle glaucoma and to compare the difference in intraocular pressure (IOP) lowering effects between 180-degree and 360-degree SLT. METHODS: This study is a retrospective consecutive chart review of open-angle glaucoma patients who had undergone first-time SLT from January of 2005 to July of 2007. All the patients had primary open-angle glaucoma or pseudoexfoliation glaucoma under medical treatment and followed for at least 3 months after the procedure. The IOP reduction and treatment success were compared with the 2 treatment types. RESULTS: Twenty-nine patients underwent 180-degree SLT (35 eyes) and 25 patients underwent 360-degree SLT (34 eyes). The average follow-up was 19.5 months (range 3 to 36) for 180-degree group and 17.9 months (range 3 to 36) for 360-degree group. During the follow-up period, the 360-degree SLT group showed significantly lower posttreatment IOP at each follow-up point relative to pretreatment IOP, and its IOP reduction rate stayed statistically higher than the 180-degree group. We found a positive correlation between the pretreatment IOP and the IOP reduction rate for 360-degree SLT. The lower the pretreatment IOP was, the lower IOP reduction rate became. A Kaplan-Meier survival analysis showed higher success rates after 360-degree SLT than after 180-degree SLT. CONCLUSIONS: The 360-degree SLT was shown to be more effective than180-degree SLT for intermediateterm reduction in IOP of Japanese patients with open-angle glaucoma as an adjunctive treatment protocol.
