Pre-ganglionic Horner’s syndrome (#1)
Top: This 31-year-old patient reported recent drooping of his right upper eyelid and was found to have 2 mm of right ptosis associated with subtle (< 0.5 mm) anisocoria. Anhidrosis of a portion of the right side of his face was also documented. Bottom:Although both pupils dilated under darkened conditions, the right pupil dilated significantly less, resulting in obvious anisocoria (> 1.5 mm).
