Trabeculectomy with Mitomycin-C in Post-Traumatic Angle Recession Glaucoma in Phakic Eyes With no Prior Intraocular Intervention

Purpose : To evaluate the outcomes of primary trabeculectomy with mitomycin-C (trab MMC) in phakic eyes with post-traumatic angle recession glaucoma with no prior intraocular surgeries. Methods : We included 32 phakic eyes of 32 patients who underwent trab MMC between January-2002 and December-2017. Complete success was IOP between 6 and 21 mm Hg without anti-glaucoma medications (AGM) and failure was when IOP >21 mm Hg with AGM or need for additional intervention for IOP control or loss of light perception. Results : Thirty-two eyes of 32 subjects with a mean age (+/- standard deviation) of 30.6 +/- 12.6 years were included. The majority were male (97.6%) and the major cause of blunt trauma were sports injury in 28/32 eyes (88%) and 24/32 eyes (75%) had >180-degree angle recession. The Median (interquartile range) follow-up duration was 1.3 years (0.3,3.5). There was significant IOP reduction at 1-year postoperatively (34 (28,40) to 13 (12,16) mm Hg; p < .001). The median postoperative AGM at 1-year was significantly less (4 (3,4) to 0; p < .001) with stable Log MAR visual acuity (p = .24). The complete survival of trab MMC was 88% at 1 year and was 77% from 2 to 5 years. Complications were intraoperative vitreous prolapse needing limited vitrectomy in two eyes and postoperative choroidal detachment in two eyes that resolved with conservative management. The contralateral eyes of three patients (9.7%) developed elevated IOP during the follow-up period. Conclusion : Trabeculectomy with mitomycin-C in phakic eyes with traumatic angle recession glaucoma showed good safety and efficacy in the medium-term follow-up. The contralateral fellow eye needs monitoring for glaucoma in these patients.
