Summary
Sphere extrusion can occur in anophthalmic cavities, often years after orbital implant surgery due to conjunctival dehiscence. This complication necessitates further surgical intervention.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Context:
- Anophthalmic cavities require orbital implants to maintain orbital volume and cosmesis.
- Sphere extrusion is a known, albeit infrequent, complication following orbital implant placement.
Purpose:
- To characterize patients experiencing sphere extrusion from an anophthalmic cavity.
- To identify potential risk factors and timing associated with this complication.
Summary:
- This retrospective study analyzed 37 patients with anophthalmic cavity and sphere extrusion.
- Extrusion occurred in both enucleated and eviscerated cavities, typically 1-2 years post-surgery.
- Conjunctival dehiscence preceded extrusion, which was observed with all implant types.
Impact:
- Highlights the possibility of orbital implant complications, including sphere extrusion.
- Emphasizes the need for patient and surgeon preparedness for potential secondary surgeries.
- Informs clinical practice regarding long-term implant management and complication surveillance.
