Alternative exotropia

Photo by Professor Chua Chung Nen

This 65 year-old woman had had a left exotropia since her teenage year. She was seen in the clinic for diabetic retinopathy screening which was unremarkable. Examination revealed normal vision in both eyes. The exotropia was alternating. When the right eye was covered the left eye took up fixation and remained even when the occlusion was removed. She was likely to have intermittent exotropia as a child which became decompensated with age. We offered her corrective surgery to improve her appearance but she declined.
