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

## TL;DR

This paper describes a rare eyelid condition involving fat prolapse and argues it should be recognized as a distinct medical entity.

## Contribution

The paper proposes a new classification for a specific type of orbital fat prolapse under the upper eyelid.

## Key findings

- The condition typically affects young patients and presents as a pseudo-occlusion in the mid-upper eyelid.
- Three cases were analyzed to delineate clinical features and surgical interventions for this distinct entity.
- The authors suggest the term Upper Eyelid Subcutaneous Orbital Fat Prolapse (UESOFP) for this condition.

## Abstract

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).
