A retrospective study of the incidence and prevalence of thermal corneal injury in patients with burns

The clinical course of thermal corneal injuries is not well described. A review of 1750 burn admissions to a regional burn center between 1979 through 1993 was done to determine the clinical course of thermal corneal injuries. Twenty-five out of 1750 burn admissions (1%) presented with a thermal corneal injury. Corneal injuries were identified with. use of a fluorescein dye and a Wood's lamp. Ophthalmologic consultation was obtained for those identified. Data were analyzed with the Fisher's exact test and the unpaired two-tailed Student's t test. Patients with thermal corneal injury did not differ demographically from other patients with burn injury. Open-flame burns were the most common cause of injury. Improvement of corneal injury occurred in all survivors who had an intact globe on initial examination. Initial visual acuity was not a good predictor of outcome, and long-term complications were uncommon.
