Orbital fat prolapse consists on the extrusion of intraconal and extraconal orbital fat to a space outside it’s anatomical bed. It is a benign condition and it can happen towards the intracranial space, the infratemporal fossa or, most commonly, the subconjunctival space.

Orbital adipose tissue (fat) is located within the orbit surrounding the globe, optic nerve, and extraocular muscles. The orbital adipose tissue is a unique collection of white fat distinct from the subcutaneous adipose tissue elsewhere in the body.

Dec 11, 2023 · Orbital fat prolapse, also referred to as orbital fat herniation, is a benign condition where the orbital fat is displaced or extruded out of its anatomical bed. The displacement of orbital fat can happen in various spaces, like the intracranial, subconjunctival, and infratemporal fossa.

Nov 15, 2021 · Orbital fat occupies the space surrounding the extraocular muscles and the globe—a protective cushion for the eye. The orbital fat is comprised of two compartments: intraconal and extraconal.

Subconjunctival orbital fat prolapse is a benign condition and most patients who present with it are asymptomatic. Their main concern is the lesions' cosmetic appearance. Many other potentially dangerous orbital pathologies can mimic subconjunctival orbital fat prolapse.

Apr 6, 2023 · Orbital fat occupies the space surrounding the eye muscles and the eye—as a protective cushion for the eye. The orbital fat is comprised of two compartments: intraconal and extraconal. Orbital fat may be prolapsed or displaced secondary to aging, trauma or surgery.

Orbital fat prolapse, also known as lower eyelid fat herniation, is a common condition that occurs when the fat pads located beneath the eyes protrude forward.

The aim of the study described here was to report the outcomes of surgery for orbital fat prolapse by conjunctival fixation to the sclera. Twenty-three consecutive eyes of 19 patients with orbital fat prolapse were retrospectively reviewed.

Intraconal orbital fat can herniate into the subconjunctival space when Tenon's capsule is violated spontaneously or after trauma or surgery. This process appears as a unilateral or bilateral, elevated, compressible, yellow-orange mass with visible lipid globules.

Sep 30, 2024 · Subcutaneous upper eyelid orbital fat prolapse often affects appearance and typically requires surgical intervention. Depending on the location of the prolapsed orbital fat, the surgery involves either a sub-brow incision or a double eyelid incision.
