Summary
Subconjunctival fat prolapse, a rare condition, involves orbital fat herniating through Tenon
Area of Science:
- Oculoplastic surgery
- Orbital anatomy
- Ophthalmic pathology
Background:
- Subconjunctival fat prolapse is a rare condition.
- Literature typically associates orbital fat prolapse with trauma or surgery.
Observation:
- The study reports on three patients presenting with subconjunctival fat prolapse.
- These patients had no prior history of trauma or surgery.
Findings:
- Subconjunctival fat prolapse is caused by the herniation of intraconal orbital fat.
- This herniation occurs between the conjunctiva and sclera, likely due to dehiscence of Tenon's capsule.
Implications:
- This condition requires careful differential diagnosis.
- Consider conditions such as lacrimal gland ptosis, lacrimal gland tumors, and lymphoid tumors.
