Glaucoma in Patients With Ocular Chemical Burns

PURPOSE: To examine the development and management of glaucoma in patients with ocular chemical burns. DESIGN: Retrospective, observational case series. METHODS: SETTING: University of Washington Eye Clinics. PATIENT POPULATION: Twenty-nine eyes (18 patients) with ocular chemical burns seen between 1997 and 2010 with a minimum of 3 months of follow-up. OBSERVATION PROCEDURE: Eyes were graded using the Roper-Hall seal MAIN OUTCOME MEASURES: Long-term use of glaucoma medications (3 months or more) and need for glaucoma sun;cry. RESULTS: The mean age was 45 +/- 17 years, with a mean follow-up of 75 +/- 47 months (median, 66 months). Roper-Hall grade III or IV eyes (n = 20) had significantly higher intraocular pressure at presentation (35.9 vs 16.4 mm Hg; P = .001) and over follow-up were more likely to require long-term glaucoma medications (P = .003) or to undergo glaucoma surgery (P = .016) than Roper-Hall grade I or II eyes. Thirteen eyes (12 Roper-Hall grade III or IV) underwent glaucoma surgery. Eight eyes underwent glaucoma tube implant surgery; 4 required at least 1 revision. Seven eyes underwent diode laser cyclophotocoagulation; 4 required repeat treatment. Most (89%) eyes had controlled intraocular pressure at the last follow-up. However, 76% of eyes with visual acuity of 20/200 or worse at initial evaluation did not have improved vision at the last follow-up. CONCLUSIONS: Eyes with Roper-Hall grade III or IV ocular chemical burns were more likely to have glaucoma line to require surgery for it. Outcomes of glaucoma management generally were good, although tube implant surgeries often had complications requiring revision. (AIR J Ophthalmol 2012;154:481-485. (C) 2012 by Elsevier Inc.
