Management of a case of Traumatic Lateral Rectus Transection – A Surprise.

ABSTRACT

A 19-year-old girl, presented with diplopia, bleeding, pain, and tissue hanging out from her right eye after a stick injury. She had uncorrected visual acuity of 20/20 and N6 in both the eyes, right eye esotropia (30 prism diopter), total limitation of abduction (right eye), and diplopia. About 10 mm of lateral rectus (LR) muscle stump was hanging from the insertion over the lid margin. Anterior and posterior segments were normal in both the eyes. The computed tomography (CT) scan showed ruptured and retracted LR. On wound exploration, the proximal part of LR was not retrievable. The cut edge of the muscle stump at the insertion site was sutured to the intermuscular septa and tenons tissue. Post-operatively, diplopia decreased, abduction in right gaze improved dramatically, and eyes were orthophoric 1 year follow-up. Post-operative CT scan was reported to have the presence of intact LR muscle.
