Secondary glaucoma after vitrectomy and phaco-vitrectomy surgeries. A tertiary care experience

Abstract

Purpose: To determine secondary glaucoma post vitrectomy and phaco-vitrectomy surgeries with or without silicon oil, gas, or scleral buckle. Materials and Methods: Ninety eight eyes from 84 patients (52 males and 32 females) were included. Preoperative intra ocular pressure (IOP) values were compared with postoperative values at the first postoperative day, one week, one month, and three months and were classified as per intraoperative techniques. Results: Patients who underwent Pars plana vitrectomy with silicon oil plus buckle and patients with Pars plana vitrectomy, gas, and buckle had 70% and 100% high IOPs, respectively, on the first postoperative day. Twenty four percent of eyes who had silicon oil injected had higher IOP compared to 11.0% who had no silicon oil. 25% of eyes who had buckle implanted had higher IOP as compared to 12.8% without buckle. At the end of 3 months, 20% of patients who underwent vitrectomy with silicon oil and laser with buckle, 30%, of eyes with gas and laser, and 20% of eyes with oil and laser were found to have high IOP. Hundred percent of eyes with gas, laser, and buckle had the highest increase of IOP on the first postoperative day, followed by oil, laser, and buckle-70 percentage and gas with vitrectomy alone-42.9 percentage. Conclusion: Secondary glaucoma remains to be an important complication in patients undergoing vitrectomy. Patients who undergo vitrectomy with gas plus oil and buckle may have significantly more chances of developing high IOP and hence advisable to consider aggressive and close management.
