Effect of phacoemulsification surgery on hypotony following trabeculectomy surgery
Doyle JW; Smith MFArchives of Ophthalmology 2000; 118: 763-765
OBJECTIVE: To review the effect of phacoemulsification surgery in eyes with chronic hypotony following trabeculectomy with mitomycin C. DESIGN: Retrospective analysis of all eyes that underwent phacoemulsification surgery for symptomatic cataracts and had a preoperative diagnosis of chronic hypotony (intraocular pressure (IOP) ≤ 6 mmHg) for at least six months following trabeculectomy with mitomycin C. Each case had at least six months' follow-up after the phacoemulsification surgery. SETTING: A tertiary care referral center. INTERVENTION: Clear cornea phacoemulsification surgery, with minimal perioperative anti-inflammatory medication and retention of viscoelastic in eyes at case conclusion. MAIN OUTCOME MEASURES: Intraocular pressure, visual acuity, and complications. RESULTS: Nine eyes of nine patients were identified. Mean preoperative IOP was 4.2 ± 1.4 mmHg; the mean postoperative IOP was 7.3 ± 2.8 mmHg (p = 0.009). Intraocular pressure increased in all but two eyes. One of these two eyes experienced an acutely elevated IOP (34 mmHg) on postoperative day 4, which dropped back to preoperative levels after trabeculectomy flap needling. Mean preoperative visual acuity was 20/300; mean postoperative visual acuity was 20/40. CONCLUSION: Phacoemulsification surgery may be associated with a statistically significant elevation in IOP in previously filtered eyes with hypotony, resulting in resolution of hypotony in some of these challenging cases.
