Ocular injury ig one of the commonest causes of eye diseases, but its patterng and incidences are variable according to the envirmment. A clinical analysis was done for 450 cases of ocular injurieg, including 99 cases of in-patients which were observed in the Department of Ophthalmology, Chungnam National University Hospital during the period of 1975~1978. The results were as follows; 1) The incidence of ocular injurieg was 4.3% of all patientg and there was the tendency to increase year by year. Ocular injuries ocupied 18.3% of all admitted patients. 2) The incidence was more common in male (80.6%) and in the age of 2nd to 4th decades (47.4%). RelativeIy higher incidence of ocular injuries were observed in children under the age of 10 (16.2%) and the damage was usually more serious. 3) The ocular injurieg were more common in the spring (27.7%) hit in children the incidence was higher during vacationg. It seemed that the ocular injuries were related to patient's occupation. 4) Small flying particles, such as sand, iron particle and dugt, were the mogt common cause of the ocuIar injurieg (31.7%), followed by the injuries with the figt (13.1%) and the wooden stick (10.8%), but the injuries with the iron and gteel were mogt common in the admitted patients (23.2% of all cases). 5) Subconjunctival hemorrhage was most frequent in the ocular injuries (21.4%) and corneal foreign body (14.8%, corneoscleral laceration (19.5%, traumatic cataract (8.0%) and subcutaneous hemorrhage (58%). In the cages of in-patients, hyphema was most common (22.6% of admitted cases), followed by corneoscleral laceration with prolapsed uveal tissue (l9.3%) and traumatic cataract (9.9%). Contusion or concussion was the most frequent nature of trauma in all cases and the perforating injury in admitted cases. 6) Surgical interventions inculded the simple suture of the cornea and the scleral (38.5% of surgical cases), the irrigation of the anterior chamber (23.6%), enucleation or evisceration (14.9%) and others. 7) At the first visit, 6.4% of all cages were totally bund and the visual acuity showed below 0.1 in 16.8%. The visual acuity in in-patients was total blindness in 9.0%, below 0.1 in 60.6% and over 0.5 in 9.0% After treatment, 49.4% of them showed the visual acuity below 0.1, reflecting a poor prognosis. But tbe number of the patients over 0.5 increased to 24.2%, showing the significanes of proper treatment immediately after injury. The prognosis of the ocular injury is generally poor in spite of proper treatment. Prevention of bundness, therefore, is mandatory through public enlightment and education propened by the society as a whole with the ophthalmologits on the leading role.
