PURPOSE: To evaluate demographics and outcomes of patients with recurrent corneal erosions related to trauma and epithelial and Bowman layer disorders. DESIGN: Retrospective case series. METHODS: setting: Wills Eye Institute, Philadelphia, Pennsylvania. study population: Two hundred seventy-two eyes (230 patients) presenting between 2008 and 2011 with recurrent corneal erosions related to trauma and epithelial and Bowman layer disorders. procedure: Conservative management, diamond burr polishing, excimer laser phototherapeutic keratectomy (PTK), and epithelial debridement alone. main outcome measure: Recurrence of erosions, more than 6 weeks after commencing treatment. RESULTS: Mean age was 46.5 ± 14.6 (2-85) years. Female subjects accounted for 53% of patients and 18.3% had bilateral involvement. Etiology included epithelial basement membrane dystrophy in 52.9% (144/272) and trauma in 25.7% (70/272). One hundred sixty-six eyes with more than a single visit were initially managed conservatively, 68 of 166 (40.9%) had diamond burr polishing, 7 of 166 (4.2%) had PTK, and 4 of 166 (2.4%) had epithelial debridement alone. Many eyes had >6 weeks follow-up: 120 of 166 (72.3%) after conservative management, 54 of 68 (79.4%) after diamond burr polishing, 7 of 7 (100%) after PTK, and 4 of 4 (100%) after epithelial debridement. Percentage of eyes with recurrence was 56.7% (68/120) after conservative management, 14.8% (8/54) after diamond burr polishing, and 28.6% (2/7) after PTK. Rate of recurrence (eye-years) was 0.74, 0.19, and 0.23 with conservative management, diamond burr polishing, and PTK, respectively. Mild haze was seen in 22.2% of eyes (12 eyes) after diamond burr polishing and 28.6% (2 eyes) after PTK. CONCLUSION: Recurrent corneal erosions are most commonly associated with epithelial basement membrane dystrophy. Patients are generally initially managed conservatively, with recurrence in more than half of eyes. Diamond burr polishing is the most common surgical intervention and is effective in a majority of eyes.
