Selective laser trabeculoplasty as adjunctive treatment in pseudoexfoliative glaucoma patients
Abstract
Introduction/Objective. Pseudoexfoliation syndrome is characterized by abnormal production and accumulation of fibrillar, white-gray, “dandruff-like” material in almost all ocular structures. The aim of this study was to examine effect of selective laser trabeculoplasty in pseudoexfoliation glaucoma patients. Methods. Thirty-two patients (47 eyes) with medically uncontrolled pseudoexfoliation glaucoma were enrolled. All the patients could not reach target intraocular pressure with maximal tolerated medical therapy before treatment. Selective laser trabeculoplasty was performed with about 100 non-overlapping spots. Intraocular pressure was measured one hour, seven days, four weeks, three, six, twelve, eighteen, and twenty-four months after the procedure. Results. The mean base intraocular pressure was 23.45 mmHg (SD = 3.07). Statistically significant reduction of mean intraocular pressure was observed at all follow-ups except one hour after treatment. Mean intraocular pressure after 24 months was 18.39 mmHg (SD = 1.82). Success, defined as intraocular pressure reduction from base intraocular pressure by more than 20% after 24 months, was achieved in 27 eyes (57.45%). We did not find any influence of sex and age on selective laser trabeculoplasty effects in pseudoexfoliative glaucoma patients. Baseline intraocular pressure is proved to be a reliable predictor of intraocular pressure-lowering effect, as there was a strong correlation between baseline intraocular pressure and the percentage of reduction of intraocular pressure after 24 months (r = 0.71, p < 0.01). Conclusion. Selective laser trabeculoplasty is a safe and effective method for the reduction of intraocular pressure in pseudoexfoliation glaucoma patients and should be used more often in this challenging form of glaucoma. Baseline intraocular pressure seems to be a reliable predictor of success.
