Current pattern of ocular trauma as seen in tertiary institutions in south-eastern Nigeria

Abstract

Background: Ocular trauma is a leading cause of monocular blindness worldwide and in developing countries, are not only more common but also more severe. Industrialization and urbanization may alter or modify prevalent aetiological factors and the presentation of ocular trauma. Objective: To determine the current pattern of eye injuries in Teaching Hospitals in Enugu State. Methods: This prospective cross-sectional descriptive study was carried out at the eye clinics and emergency units of two tertiary institutions in Enugu, Nigeria. Consecutive ocular trauma patients were enrolled over a 5-month period. On presentation, they underwent ocular examination including visual acuity (which was categorized according to the WHO classification of visual impairment and blindness}, anterior and posterior segment examinations. Injuries were grouped using the Birmingham Eye Trauma Terminology system. Results: Within the study period, 2545 new patients presented to the hospitals where the study was conducted. A total of 89 patients presented with ocular trauma, giving an incidence of 3.5%. The male to female ratio was 1.3:1 and patients aged 10 to 19 years formed the majority (24%). Domestic accidents (22%) were the most common cause of ocular injuries while blunt objects (57%) were the most common agents. Closed globe injuries constituted 76% of all injuries. Forty-three per cent of patients presented within 24 h of injury. Conclusion: Ocular trauma is still prevalent in South-eastern Nigeria and there has indeed been a change in the pattern as well as the incidence. Assault and road traffic accidents have emerged as important causes of eye injuries. In addition, there has been an improvement in the health-seeking behaviour of people living in Enugu and this may reflect positively on the uptake of recommended preventive strategies.
