A young man of 22 years, named Gopal was admitted in the Government Erskine Hospital, Madurai on 15-9-1959 with a history of injury of the right side of his face.
History:-Our patient, a man from the hill-tribe, went for collecting firewood in the forest in the Western Ghats on 13th September evening. Suddenly he was attacked by a black bear, which struck him on the right side of his face with paw, and pulled out the right eye.
Condition on Examination:- Patient was having extensive lacerated wound of right side of face, including the right maxilla and forehead. The right eye was hanging loose with very little attachment to the orbit. There was no vision in the eye and it was excised immediately. The wound was sutured and dressed. The patient was discharged after two weeks at his request.
On 22-11-1959, the patient again reported to the hospital, with a complaint of defective vision in the left eye. On examination, there was no evidence of external injury to the left eye or left side of face.
Vision was counting fingers at 1 metre in left eye.
Fundus showed a pale disc.
Blood for Kahn was negative.
There was discharge of pus from the right orbit. X-ray of right orbit revealed fracture of right maxilla and the orbital bones. A study of the visual field of the left eye was made and there was a clear hemianopic loss of temporal half. The wound was dressed again and had a course of Penicillin and Streptomycin injections and Vitamin B Complex. The wound healed and he was discharged at request on 4-1-1960. Vision at the time of discharge in the left eye was 6/12 but still defective in the temporal field as before.
Discussion:-The interesting point in this case is the loss of temporal half of field of vision in the left eye which had no injury to it. The possible explanation is that the right eye was pulled violently by the bear, with the associated injury to the apex of the orbit. The might have involved the optic chiasma, and left optic nerve. There must have been a traction injury to medial fibres of the left optic nerve causing the temporal hemianopia.
Summary:- A case of mauling by a bear with an avulsion injury to right eye with loss of visual field in the left eye is reported. A case like this, has not been reported previously in the Ophthalmic literature.
