Materials and Methods: The files of patients with NVG who underwent trabeculectomy with mitomycin C and AGV implantation between April 2012 - May 2017 were retrospectively analyzed. Detailed ophthalmologic examination was performed at the time of admission and at the controls. Age, sex, follow-up period, best corrected visual acuity (BCVA), intraocular pressure (IOP), complications were recorded. IOP between 5 and 21 mmHg was accepted as surgical success. Paired-t test was used for statistical analysis, p<0.05 was considered signifi cant.
Results: Twenty of 40 patients with NVG underwent trabeculectomy and 20 of them had AGV implantation. In the trabeculectomy group, 12 (60%) were male and 8 (40%) were female, age 54.3 ± 15.56; In the AGV group, 11 (55%) were male and 9 (45%) were female and their age was 53.1 ± 18.59. The follow-up period was 14.3 months in the trabeculectomy group and 15.1 months in the AGV group. There wasn?t statistically signifi cant difference in visual acuity between groups at the time of admission and at the 12th month (p=0.41). IOP was 42.35±8.66 mmHg in the trabeculectomy group and 40.61±7.85 mmHg in the AGV group before the treatment; 14.99±4.55 mmHg and 15.09±4.38 mmHg respectively in the 12th month (p=0.53). Surgical success rate was 73% in trabeculectomy group, 65% in AGV group (p=0.32). There were shallow anterior chamber in 4 (20%) patients in the trabeculectomy group, 4(20%) had hyphema, 3(15%) had hypotonia, 3(15%) had cataract, 2(10%) had vitreous hemorrhage, 1(5%) had choroidal detachment, 1(5%) had retinal detachment, 1(5%) had blebitis-induced endophthalmitis. 4(20%) patients in the AGV group had encapsulated bleb, 3(15%) had shallow anterior chamber, 2(10%) had hypotonia, 2(10%) had hyphema, 1(5%) had corneal oedema.
Conclusion: There was no statistically significant difference between trabeculectomy with MMC and AGV implantation in patients with NVG. As a result, both surgeries can be preferred as a primary procedure.
