ABSTRACT
Ocular trauma remains a leading cause of visual loss internationally, most often affecting men. Patients are usually aged less than 30 years; trauma may be associated with alcohol and illicit drug usage. The patterns of ocular trauma are constantly changing depending on social, demographic and geographical variations. In blunt trauma, the most common break is an inferotemporal dialysis with superonasal quadrant as the next most common. The patient may not be symptomatic for some time because of the slow onset of detachment and late detachment of the macula. Blunt trauma may rupture the eye wall, most commonly, the sclera at the limbus or posterior to the extraocular muscle insertions often with immediate loss of the crystalline lens and prolapse of the choroid and retina. There are two models for the prediction of visual outcome in open globe injury, the ocular trauma score (OTS) and the classification and regression tree; both have been found to be predictive of outcome.
