Divergent Strabismus Fixus - A Case Report

Abstract

Strabismus fixus is a rare condition and usually is of convergent type in which one or both eyes are anchored in a position of extreme adduction. Convergent type strabismus fixus is considered to be a congenital disorder and a part of congenital extraocular muscle fibrosis syndrome. Villasecca and Martinez described an acquired type of strabismus fixus. Hayashi et al reported that progressive esotropia could develop into the acquired type of convergent strabismus fixus. There are very few reports of divergent strabismus fixus in the literature. It may or may not be accompanied by ptosis or generalized extraocular muscle fibrosis. In our report, a case of divergent type strabismus fixus is described and discussed.

Exotropia-Hypotropia Complex in High Myopia

“…In the current study, because most of the patients had full or nearly full ocular versions, the strabismus did not qualify as myopic divergent fixus variety, as has been described previously. [5][6][7] In our study, the majority of the cases had unilateral high myopia, whereas most reported cases of myopic convergent strabismus fixus were reported to be bilateral. 8 Regardless of age of onset, all of our patients gave recent history of progression of their deviation.…”
