Objective To analyze the clinical characteristics and to explore the diagnosis and treatment measures for the cornea damage caused by high-voltage electric arc.Methods Patients with cornea damage caused by high-voltage electric arc were collected from Sep 2010 to Dec 2012.The diagnosis was based on the slit lamp and cornea fluorescein staining examination and the cornea bums degree grading was based on the grading standards formulated by the national ocular trauma and occupational eye disease association in 1982.The clinical features and efficacy were retrospectively analyzed and the treatment and preventive measures were summarized.Results Thirty-five cases with 70 eyes were collected.The cornea burns degree grading was as follows:16 eyes (23％)of degree Ⅰ,42 eyes (60％) of degree Ⅱ,12 (17％) eyes of degree Ⅲ and no one of degree Ⅳ.The cornea epithelial exfoliation area grading was as follows:10 eyes (14％) of "+",30 eyes (43％)of "++",30 eyes (43％) of "+++".The cornea of 68 eyes (97％) were completely healed,the visual acuity of 67 eyes (96％) recovered to the pre-injury level.Conclusions Cornea damage caused by high-voltage electric arc can receive satisfactory prognosis with proper and prompt treatment.
