Combined trabeculectomy and vitrectomy for intractable glaucoma with severe ocular contusion involving the posterior segment.
Chinese Medical Journal 2011 August
BACKGROUND: Intractable secondary glaucoma with severe ocular contusion involving the posterior segment is difficult to treat. In this study, we evaluated the safety and efficacy of combined trabeculectomy and vitrectomy for intractable glaucoma with severe ocular contusion involving the posterior segment.
METHODS: This retrospective interventional study enrolled 18 eyes from 18 consecutive cases with uncontrolled intraocular pressure, angle recession exceeding 180°, dense vitreous hemorrhage, and/or limited retinal detachment after severe ocular contusion. Combined trabeculectomy and vitrectomy was performed after giving the patient sufficient anti-inflammatory and intraocular pressure (IOP)-lowering medication. Follow-up averaged 26.2 (range, 6.0- 48.0) months.
RESULTS: The mean IOP decreased from (36.4 ± 10.0) mmHg on maximum IOP-lowering medications to (14.6 ± 4.4) mmHg on (0.7 ± 1.2) topical medications at the final follow-up (P < 0.0001). During the first postoperative month, four eyes (22%) had a short hypertensive phase and six eyes (33%) had early hypotony, including one case (5.6%) of bleb leakage. Seven eyes (39%) developed recurrent hypertension 3- 6 months postoperatively, five of which were controlled by topical medications. Ten (55.6%) eyes were classified as a complete success, five (27.8%) as a qualified success, and three eyes (16.7%) as failures. Kaplan-Meier survival analysis for complete and cumulative success showed 53.5% and 80.0% survival at 48 months, respectively. Visual acuity was improved in 15 eyes (83.3%). Three eyes (16.7%) had unchanged visual acuity, one (5.6%) of which developed atrophia bulbi despite a normal intraocular pressure. No recurrent retinal detachment or vitreous hemorrhage developed.
CONCLUSION: Combined trabeculectomy and vitrectomy is a viable surgical procedure for the management of intractable glaucoma with severe ocular contusion involving the posterior segment in selected cases.
