—Anterior segment ischemia has been considered a rare complication following strabismus surgery and generally does not occur unless three or four rectus muscles are removed from the globe.1 Surgery involving two rectus muscles was reported to have caused anterior segment ischemia in a patient with chronic lymphocytic leukemia.2 Fells and Marsh3 noted mild signs of ischemia and ocular circulatory abnormalities in an unspecified number of patients following surgery on two rectus muscles.
Report of a Case.
—A 42-year-old woman, with a history of a previously treated hyperfunctioning adenoma of the thyroid gland, was found to have left upper eyelid retraction and bilateral restriction of supraduction and abduction with 25 diopters of esotropia and 7 D of hypertropia OS in the primary position. Exophthalmometric readings were 19 mm bilaterally. Results of the remainder of her examination were normal. A computed tomographic scan demonstrated bilateral enlargement
