All consecutive patients referred to Vitreo-retina service during 1 year period were examined.Out of total 523 eyes registered large proportion was <25years of age (67%), males (88%) and literate (77%). Forty-four percent belonged to rural area and 38% were students. Most of the open globe injuries were Zone 1(50.8%). 75% presented >1 week after injury. The incidence of intraocular foreign body and retinal detachment was 17.4, and 11.3% respectively. Diagnosis of post traumatic endophthalmitis was made in 20.5% of open globe injuries. Development of endophthalmitis correlated with younger age, rural setting, illiteracy, presence of foreign body and lens disruption. Ocular trauma requiring tertiary care commonly affects young students, labourers and factory workers. Younger, rural and illiterate patients are more likely to develop infection especially if they have lens injury or intraocular foreign body.

Five hours after surgery the patient had no light perception. There was no intraoperative or postoperative rise of intraocular pressure or central retinal artery ischemia. Immediate removal of the explant brought a return of light perception and postoperative visual acuity improvement. The episcleral explant may have caused the direct optic nerve trauma that resulted in loss of vision.

Materials and Methods: Retrospective review of records. The cases were grouped according to the Ocular Trauma Classification Group classification system. Results: Out of 188 MLCs, 164 (87.2%) were male. Mean age (±standard deviation) was 31.6 (±12.7) years. Age ranged from 7 to 75 years. Twenty‑six (13.8%) patients had bilateral involvement. The fist was the most common mode of injury, which was seen in 109 (58%) cases. A total of 27 (14.3%) patients had associated extraocular injury. No evidence of ocular or orbital trauma (malingering) could be found in 13 (7%) patients. Mechanical trauma was present in 169 (90%) patients with injury to globe in 129 (69%) patients and injury to lid or orbit without damage to the globe in 40 (21%) patients. Chemical injury was observed in 6 (3%) patients. Closed globe injury (CGI) was seen in 116 eyes and open globe injury (OGI) was noted in 29 eyes. The most common type of injury, zone, pupil, and grade of injury in CGI were Type A or contusion (79%), Zone I (72%), Pupil B (absence of relative afferent pupillary defect) in 95%, and Grade A [visual acuity (VA) ≥20/40] in 68% of the eyes, respectively. The most common type of injury, zone, pupil, and grade of injury in OGI were Type B or penetrating (48%), Zone II (38%), Pupil B (59%), and Grade D (VA 4/200‑light perception) (42%), respectively. Conclusions: The most common form and mode of ocular injury in MLC were closed globe injury and fist, respectively. The most common type of injury in CGI and OGI was contusion and penetrating injury, respectively. Key words: Birmingham eye trauma terminology, chemical injury of eye, malingering, ocular trauma,
