Occupational Cow Horn Eye Injuries in Ibadan, Nigeria

This case series aims to describe the clinical features, management, and outcome of occupational eye injuries caused by cow horns and to recommend possible preventive measures. A review of patients with cow horn inflicted eye injuries seen at the University College Hospital, Ibadan between January 2006, and December 2011 was conducted. Three patients were identified, and their charts were reviewed for demographic information, mechanism of injury, initial and final visual acuity, surgeries performed, as well as anatomic and visual outcome. The three patients were males and were aged 45, 22, and 49 years, respectively. They were all involved in cattle-related jobs, and they all had unilateral open-globe injuries with corneoscleral lacerations. Presenting visual acuity was nil light perception in the injured eyes. The contralateral eyes were all normal. Two of the patients required evisceration of the eye, while the third patient underwent repair of lacerations. Visual improvement was not achieved in any of the patients. Cow horn eye injuries may be quite severe and could result in loss of the eye with monocular blindness. Careful attention must be paid to prevent such injuries. Cattle rearers and dealers should wear safety goggles, and proper restraint of the animals is advocated.
