This study compared the efficacy of modified CO laser-assisted sclerectomy surgery (CLASS) with combined CLASS and trabeculectomy (CLASS-TRAB) in patients with uveitic glaucoma (UG). UG patients who underwent CLASS-TRAB between August 2015 and April 2019 were retrospectively compared with a control group who underwent a modified CLASS standalone procedure during the same period. Visual acuity, intraocular pressure (IOP), use of supplemental medical therapy and postoperative complications were recorded at baseline, 1 week, 3 months, 6 months and 12 months. Forty patients (40 eyes) were enrolled, and each group had 20 patients (20 eyes). The age and sex distribution were matched between groups (P > 0.05). Both the preoperative IOP (CLASS: 34.9 ± 9.3 mmHg, CLASS-TRAB: 36.8 ± 8.7 mmHg; P > 0.05) and number of glaucoma medications (CLASS: 3.3 ± 0.4, CLASS-TRAB: 3.5 ± 0.5; P > 0.05) were relatively higher in the CLASS-TRAB group than in the CLASS group. At the final follow-up, the IOP (CLASS: 12.9 ± 3.4 mmHg, CLASS-TRAB: 11.2 ± 2.5 mmHg) and number of glaucoma medications (CLASS: 0.4 ± 0.7 and CLASS-TRAB: 0.2 ± 0.5) significantly decreased in both groups (P < 0.01). Both the complete success rate and qualified success rate were comparable between the two groups (CLASS versus CLASS-TRAB: 55% versus 80%, P = 0.09; 80% versus 95%, P = 0.34). CLASS-TRAB is as efficient as modified CLASS in terms of the IOP-lowering effect, providing a new option for patients with UG that is severe and ineligible for other treatments.
