ABSTRACT
A 49-year-old woman with a history of hyperthyroidism was treated with radioactive iodine 3 months ago. She is now on hormone replacement and her thyroid function is stable. She noticed progressive periorbital swelling, conjunctival redness, and double vision since 1 month. There is no variability in the diplopia. She stated that her vision is unchanged. Her visual acuity is 20/20 OU and no relative afferent pupillary defect was seen. She has an esotropia of 35 prism diopters and a right hypotropia of 6 prism diopters in primary position. Her external appearance and ocular motility photographs were taken postdilation and are shown in Figure 16.1. Discrete superficial punctated keratitis was seen OU. Fundus examination was within normal limits.
