Upper eyelid subcutaneous orbital fat prolapse: A case series on a condition that deserves a separate name.

In the field of ophthalmology, orbital fat prolapse under the upper eyelid is less recognized than subconjunctival orbital fat prolapse. Despite its occasional occurrence in clinical practice, this condition is often inadequately understood and incorrectly classified due to its subtle manifestations and the limited number of focused studies. Typically affecting young patients, the prolapse is located subcutaneously in the mid-upper eyelid, resulting in a pseudo-occlusion. This study aims to investigate this specific ocular anomaly, we delineate the clinical presentations, surgical interventions, and differential diagnoses of this condition through three representative cases, proposing its classification as a distinct disease entity named Upper Eyelid Subcutaneous Orbital Fat Prolapse (UESOFP).
