Abstract
Purpose: The position of the globe relative to the orbital rim plays a sign ificant role in the relationship between the eyelids and the cornea. A prom inent globe (relative proptosis) may cause eyelid retraction and exposure k eratopathy. Simple horizontal lower eyelid tightening exacerbates eyelid re traction. Optimal correction with an orbital decompression or advancement o f the orbital rim entails considerable risk. A technically simpler alternat ive, placement of an orbital rim onlay implant, was evaluated. Methods: Fourteen patients with symptomatic relative proptosis underwent pl acement of a porous polyethylene orbital rim onlay implant. Results: Lower eyelid position, exposure keratopathy, and ocular discomfort were improved in all patients. Two patients required minor surgical revisi ons. Conclusions: Porous polyethylene orbital rim onlay implants are a satisfact ory option to treat the sequelae of relative proptosis.
