Abstract

Abstract: : Purpose: Blepharoptosis is common in an anophthalmic orbits, and levator function is an important factor in correcting blepharoptosis. This is to evaluate the levator function of an ophthalmic orbit. Methods: Levator function was measured bilaterally in unilateral anophthalmic patients with various heights of prostheses inserted, in whom the bilateral levator muscles and their innervation were thought to be normal. Results: Levator function was lower in anophthalmic orbit than in contralateral normal orbit (paired t–test, p<0.05) irrespective to prosthesis heights. In the anophthalmic orbit, smaller the heights of the prosthesis, smaller the levator function measured (linear regression, p<0.05). Conclusions: When using the levator function of an anophthalmic orbit to correct blepharoptosis, its underestimation must be considered.
