PURPOSE To investigate the current practice of enucleation with or without orbital implant for retinoblastoma in countries across the world. METHODS A digital survey identifying operation techniques and material used for orbital implants after enucleation in patients with retinoblastoma. RESULTS We received a response of 58 surgeons in 32 different countries. A primary artificial implant is...

The removal of an eye is one of the most difficult and dramatic decisions that a surgeon must consider in case of severe trauma or life-threatening diseases to the patient. The philosophy behind the design of orbital implants has evolved significantly over the last 60 years, and the use of ever more appropriate biomaterials has successfully reduced the complication rate and improved the patient...

BACKGROUND Temporalis fascia has been recommended for hydroxyapatite sphere exposure. The aim of this study was to identify potential risk factors for exposure of porous polyethylene (Medpor) sphere implants and evaluate the use of autogenous temporalis fascia as a patch graft for exposure. METHODS A retrospective review of consecutive cases of porous polyethylene sphere orbital implant expos...

BACKGROUND We present 6 cases of bacterial infection that developed after porous orbital implant surgery. CASES Five patients with hydroxyapatite implants showed lid swelling, discharge, and suppurative granuloma 14 days to 3 years after surgery. The hydroxyapatite implants were removed 14 days to 41 months postoperatively, and synthetic porous polyethylene orbital implants were inserted. Thi...

Squamous cell carcinoma of the eyelid is the second most common malignant neoplasm of the eye with the incidence of 0.09 and 2.42 cases/100 000 people. Orbital invasion is a rare complication but, if recognized early, can be treated effectively with exenteration. Although with advancements in technology such as computer-aided design and computer-aided manufacturing, material science, and retent...

BACKGROUND A blow-out fracture is one of the most common facial injuries in midface trauma. Orbital wall reconstruction is extremely important because it can cause various functional and aesthetic sequelae. Although many materials are available, there are no uniformly accepted guidelines regarding material selection for orbital wall reconstruction. METHODS From January 2007 to August 2012, a ...

OBJECTIVE To evaluate the use of computer-assisted designed and manufactured (CAD/CAM) orbital wall and floor implants for late reconstruction of extensive orbital fractures. METHODS We performed a retrospective data review on 29 patients treated for extensive orbital fractures from January 1, 1997, through December 31, 2007, at the University College London Hospitals. The use of a CAD/CAM te...
