Abstract
Nature offers protection to the eye, anatomically by its situation in the elastic fatty tissues of the orbital cavity and sturdy bony projections of the orbital rim and the nose, physiologically by the vigilance exercised by the blink reflex and the head – turning reflex on the approach of objects. Despite these protection injuries to the eyes are common and may involve any tissue1. Moreover, the effects of such injuries are much more severe than in any other parts of the body, because of the delicacy of the ocular tissues. Ocular injuries therefore assume marked social and economic importance involving a huge cost in human unhappiness and economic inefficiency. In our study males were predominantly affected by penetrating injuries The age group 16-45yrs was the most common group to get penetrating injuries. The majority of penetrating injuries were occupational. Metal was the most common object involved in causing penetrating injuries. Patients who presented immediately within 24hrs of injury had good visual prognosis than those presented late. Though Wound repair is the most common intervention in the primary procedure some patients underwent cataract extraction and IOL implantation, foreign body removal. Traumatic cataract was the most common complication associated with penetrating injuries. Five patients in our study had Endophthalmitis. Cataract extraction with IOL implantation is the most common secondary procedure in our study. Visual acuity at the time of presentation is one of the most important prognostic factors in predicting visual outcome. Patients who presented with RAPD had poor visual outcome. Zone I is the commonest location of laceration followed by Zone II and then Zone III. Patients who had Zone I injury had better visual prognosis than those with Zone II or Zone III injuries. Visual acuity at the time of presentation, presence of Relative afferent pupillary defect, Zone of involvement and the size of laceration are the important factors in predicting the visual prognosis. Importance should be laid on preventive measures by educating people on ocular trauma, use of protective eyewear and timely management.
