Subconjunctival Orbital Fat Prolapse: An Update on Diagnosis and Management.

Subconjunctival prolapse of orbital fat is an uncommon clinical entity in which intraconal orbital fat herniates into the subconjunctival space. Its diagnosis is mainly clinical in character and usually based on palpation, patient clinical history, and lesion features along with a slit lamp examination. Its pathophysiology remains unclear. Although frequently asymptomatic, clinical features may simulate conditions such as a prolapsed lacrimal gland, orbital lymphoma or dermolipoma and may worsen over time. In such cases, surgical removal or repositioning of the herniated fat may be necessary. While several surgical techniques have been described, no reports exist of a customized approach to manage this condition. This paper reviews the diagnosis and management of subconjunctival orbital fat prolapse.

Pericranium grafts for exposed orbital implants: An observational case-series study.

OBJECTIVE: The aim of this article is to highlight our experience with autologous pericranium graft in wide exposures (≥3 mm). The pericranium graft was taken from the parietal region of the scalp in six consecutive clinical cases of orbital implant exposure in anophthalmic sockets. MATERIAL AND METHODS: This is a prospective, descriptive case series study of patients who had orbital implant exposures and were treated with autologous pericranium graft. RESULTS: The average postoperative follow-up period was 10 months, and the mean time for conjunctivalization of the graft was 3 months. In all cases, complete conjunctivalization was achieved, and no re-exposure of the implant was observed. CONCLUSIONS: The pericranium graft from the parietal region is an effective technique to treat both small and large orbital implant exposures with no comorbidity. Time to complete conjunctivalization is similar to that of other autologous grafts. It is a simple and convenient method for the oculoplastic surgeon that constitutes a good alternative for covering anophthalmic cavities. Further studies with more cases and longer follow-up are required to confirm the effectiveness of this technique.
