ABSTRACT
PURPOSE: To evaluate the efficacy of topical erythropoietin for chemical burn induced scleral necrosis. METHODS: This study included 18 eyes of 16 patients with chemical burn induced scleral necrosis who presented within 6 weeks of the injury. In the prospective arm, 11 eyes received topical erythropoietin, 3000 IU/mL every 6 h, along with standard medical treatment. Retrospectively, we included 7 consecutive eyes of 7 patients who were managed with conventional treatment as historical control group. The main outcome measure was healing of avascular scleral lesions. The secondary outcome measure was complete re-epithelization of cornea. RESULTS: Mean patient age was 39.8 ± 16.2 years in the erythropoietin group, and they presented 16.6 ± 15.2 days after acute chemical injury. Scleral necrosis improved in all eyes after 30.7 ± 23.2 days of treatment with topical erythropoietin. Corneal epithelial defects were completely healed in 10 eyes 61.9 ± 50.7 days after the start of the medication. In comparison, standard medical treatment alone did not improve scleral necrosis in the historical control group, necessitating ocular surface reconstruction including conjunctival advancement (1 eye) and tenonplasty (6 eyes). CONCLUSION: The results of our study showed that topical erythropoietin was effective in the management of chemical burn induced scleral necrosis. This treatment could avoid ocular surface reconstruction procedures in inflamed eyes.
