CME Credits: 1.00
Released: 2022-03-10
A patient in their 60s with a medical history of hypertension was referred for new-onset fluctuating diplopia and worsening right upper eyelid ptosis. The patient underwent right-sided ptosis repair at another hospital less than 1 year earlier without improvement. Best-corrected visual acuity was 20/30 OU, and pupil examination revealed no anisocoria or afferent pupillary defect. Color vision was full in both eyes. External examination revealed a margin reflex distance 1 (MRD1) of 0 mm OD, 4 mm OS without fatigability in extended upgaze (A). The patient had a small exotropia in primary gaze with a -2 supraduction deficit. No proptosis was observed. An ice pack was applied in the clinic to the ptotic eyelid for 2 minutes, which led to a 1.5-mm improvement (B) in ptosis and no appreciable change in strabismus. The patient reported no associated headache, weakness, or difficulty swallowing.
