Abstract

Purpose: To investigate the incidence, risk factors, time course and prognosis of ocular surface complications after trabeculectomy. Procedures: This is a retrospective, case-control study. Data on 399 consecutive patients who underwent trabeculectomy between 1999 and 2009 were evaluated. Cases of postoperative corneal epithelial defects, filamentary keratitis and dellen were evaluated. The risk factors for these ocular surface complications were analyzed with a logistic regression model. Results: Corneal epithelial defects were found in 44 of the 399 patients (11%), filamentary keratitis in 12 patients (3%) and dellen in 7 patients (2%). Dellen required surgical intervention at a statistically significantly higher rate than corneal epithelial defects or filamentary keratitis (p = 0.0001, Fisher's exact test). The significant risk factors for these ocular surface complications were found to be a history of preoperative superficial punctate keratopathy (odds ratio, OR: 2.10, 95% confidence interval, CI: 1.25-3.51, p = 0.005) and a history of diabetes mellitus (OR: 1.69, 95% CI: 1.02-2.81, p = 0.04). Conclusions: Ocular surface complications following trabeculectomy are not rare. The biggest risk factors for these complications were found to be a history of preoperative superficial punctate keratopathy and a history of diabetes mellitus. Surgery is likely to be required for the treatment of dellen.
