Ptosis (short for blepharoptosis) describes a droopy upper eyelid caused by muscle weakness or paralysis. Dermatochalasis refers to excess upper eyelid skin that, if extensive enough, could cause a droopy upper lid. Ptosis repair is accomplished by strengthening or, in rare cases, replacing the muscle function that opens the eye.

Lid lag in some instances may be difficult to detect because patients with pretectal dysfunction may have downgaze paralysis early in their course that precludes the ability to detect lid lag.

The ptosis associated with Horner syndrome is mild, typically only 1mm to 2 mm, and is due to lack of innervation to Müeller’s muscle in the upper eyelid. Ptosis in Horner syndrome can be variable and may even be absent in up to 12% of cases. Miosis occurs due to loss of sympathetic tone of the pupillary dilator muscle.
