Demographic characteristic and information regarding the burn were obtained. The Hughes-Roper-Hall classification was used for grading the severity of injury. All patients were reevaluated 6 weeks later after injury. Results: Of 250 patients with complete follow-up, 155 cases (62%) were male, and 95 cases (38%) were female. Chemical injury were more common in the 20-40 years age group (108 case =43/2%).The most common cause of chemical injury were occupational injury (120 case = 48%). 127 case (50/8%) of patients referred during the first hour after injury. The most common material of injury was acid in 102 cases (40/8%).Grade I burn was seen in 92 cases (36/8%) and grade IV in 30 cases (12%).Grading of the injury was related to the referring time after chemical burn. Severity of injury was more in alkaline burn. In 50% of grade IV causes the burn had alkaline origin; however only 13/3% of acid burn had grade IV severity. (p: 0/001) Conclusion: The incidence of ocular chemical burn was approximately 2/19% of all patients who referred to emergency ophthalmology service.
