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.
