Abstract:
Subclinical ptosis is a common congenital abnormality of bilateral upper eyelid development; the clinical manifestations are upper eyelid skin covering the upper corneal margin of more than 2 mm, upper eyelid bloat, narrow lid fissure, often accompanied by epicanthus and eyebrow elevation when the eyes are opened. Patients often present with a single eyelid, which can be easily missed and misdiagnosed. The cause of subclinical ptosis is an increase in the afterload of the levator muscle during contraction due to a variety of reasons, such as gravitational, volumetric, and tensile loads; the clinical manifestations and the normalisation of the levator muscle strength are the main basis for diagnosis and identification of true ptosis. Depending on the type of afterload, different surgical treatments are available, such as blepharoplasty, orbicularis oculi myotomy, upper eyelid tissue reduction, fibrous mesh band release, anterior displacement of the levator complex, and shortening of the levator complex.
