Background: Ocular injury is one of the major causes of monocular visual impairment andrnblindness worldwide with significant socioeconomic impact.rnObjective: To evaluate the incidence, causes and visual acuity at presentation of ocular traumarncases presented to Menelik II Hospital over two months period.rnVrnMethods: A prospective cross sectional hospital-based study was conducted at Menelik IIrnHospital in Addis Ababa from April to June 2014. All consecutive emergency patients withrnocular trauma who presented to the hospital were examined. A structured questionnaire was usedrnto evaluate the causes, type of injury and visual acuity at presentation of trauma cases. Therncollected data were cleaned and analyzed using SPSS for Windows version 20.rnResult: Out of a total of 2765 patients seen at the department during the study period, 204 werernemergency ocular trauma cases making the incidence of ocular trauma to be8 per 100ocularrnpatients over two months. There were 147(72.1%) males and 57(27.9 %) females, the male tornfemale ratio being 2.6.Sixty seven (32.8%) cases of ocular injury were among the 21-30 year agerngroup followed by those in the age group 11-20 year which occurred in 46(22.5%) cases.rnProfessionally, construction workers, farmers and welders sustained trauma to the eye in 38rn(18.6%), 34 (16.7%) and 32 (15.7%) cases respectively. Unilateral involvement was seen in 190rn(93.1%) of the cases while bilateral ocular trauma occurred in 14 (6.9%) patients. Blunt injuryrnconstituted 116 (56.9%) patients and penetrating injury occurred among 71 (34.8%) cases.rnRegarding patient arrival for treatment, 180 (88.2%) came for medical care after 24 hours havernelapsed. Twenty patients (9.8%) were blind in the involved eye.rnConclusion: The incidence of ocular trauma was 7.3%.Ocular trauma was more prevalent inrnmales and productive age groups. The common cause of ocular trauma was foreign bodyrnfollowed by fighting. Of 204 cases half of them were accidental. This study was able to provide arnbetter understanding of the cause and incidence of ocular trauma.rnOur study showed that the patients with ocular injury need urgent medical treatment. Healthrneducation about proper use of eye goggle and prompt medical management can prevent thernpermanent visual loss. Education about proper use of eye goggle and prompt medicalrnmanagement can prevent the permanent visual loss from ocular injury
