Abstract
To compare clinical outcomes between gonioscopy-assisted transluminal trabeculotomy (GATT) and trabeculectomy (TRAB) in patients with advanced-stage pseudoexfoliation glaucoma (PEXG). This comparative study comprised 62 patients who underwent GATT (N = 31) or TRAB (N = 31) for advanced-stage PEXG. Primary outcome was cumulative probability of surgical success at the end of 12-month follow-up. Success was determined as intraocular pressure (IOP) reduction ≥ 30% from baseline, IOP between 6 and 18mmHg and IOP upper limits for IOP < 15mmHg and < 12mmHg, separately. Secondary outcomes were IOP reduction, antiglaucoma medication (AGM) use, and complications in the study. Age, sex, cup/disc ratio, mean deviation, pattern standard deviation, and retinal nerve fiber layer thickness did not significantly differ between the groups (p > 0.05 for all). The probability of cumulative surgical success at the end of 12months was similar between the two groups for IOP < 15mmHg and < 18mmHg but significantly higher after TRAB (92.0%) than GATT (82.5%) for IOP < 12mmHg (log-rank test p = 0.035). Percentage of IOP reduction from baseline was similar between the groups (53.1 ± 18.6% in GATT group and 53.0 ± 16.6% in TRAB group, p = 0.98) at the end of 12months. No significant difference in the mean number of AGM was present at the 12-month visit (1.3 ± 1.4 in GATT and 1.1 ± 1.4 in TRAB, p = 0.65). At the end of 12months, IOP reduction rate was similar between GATT and TRAB. Cumulative surgical success was higher after TRAB than GATT for IOP < 12mmHg.
