AbstractFR.19.01 Ocular trauma in Oman accidental major force as a primary cause of preventable blindness Abdul Hadi R. N.1, Shenoy R.1, Bialasiewicz A. A.1, Al-Belushi H.1, Evjen N.2, Rizvi G.3
1Department of Ophthalmology and School of Ophthalmic Technicians, 2Department of Anesthesiology and ICU, 3Department of Epidemiology and Statistics, College of Medicine and Health Sciences, Sultan Qaboos University, Muscat, Oman Objective: To provide incidence and outcome data of trauma in a tertiary care eye health institution in Oman and to suggest strategies for the prevention of eye injuries
Methods: In a retrospective cross-sectional nonrandomized study outcomes of trauma cases were evaluated in 146 patients with 147 eyes (male: 72.8%, female: 27.2%) from 2000-2005.
Results: 58% of patients were <20 years old, 60% of males were <20 years, 53% of females were <20years. Closed globe (61 eyes) injuries: contusion: 17, burn: 9, lamellar lacerations: 35 injuries. Open globe (86 eyes): rupture: 8, penetrating injury: 31, double perforating injuries: 47. Of the open globe injuries, 79% were mechanical, 14% combined, others chemical, thermal and electrical. 42% were caused by sharp instruments, 31% by road traffic accidents, 18% by stones, 3% by falls. Of 37 injuries with sharps, knives, sickles, or axes were most frequently involved (18), steel wires (4), gunshots and explosives (4), pencils or pens (4), thorns and leaves (4) and bird pecks (3). Accidental major force contributed to 75/147 (50%) of injuries with road traffic accidents (36), knives, sickles, and axes (18), assaults (17), guns and explosives (4). Workplace-related injuries are rare. Surgery: Of 147 interventions, surgeries of the cornea and sclera were done in 121, vitreoretinal 92, lens 32, iris 26 lid and adnexae 13 eyes. 49 patients had sought traditional medicine prior to surgery and 64 after surgery. Visual outcome was not good in these mostly young patients: 0.5-1.0 =19, 0.1-0.3: 16, FC=13, HM=29, LP=32, NLP=38.
Conclusions: Ocular trauma in Oman most frequently affects young males involving sharp objects and accidental major force injuries, which are preventable. The visual outcome is frequently poor.
