Abstract
Purpose: :
The goal of this study is to describe transcaruncular orbitotomy as an alternative technique to approach medial rectus muscle in large esotropia fixus, due to high myopia or orbital fracture.
Methods: :
Three patients with great angle esotropia (strabismus fixus), one due to medial orbital fracture and two due high myopia, were submitted to surgery to correct strabismus. All of them had esotropias of more than 100 prism diopters, with eyes positioned in extreme adduction, with hidden medial limbus. A transcaruncular anterior orbitotomy incision was made through the conjunctiva, between the plica and the caruncle to access the medial rectus muscle, so as that the recess procedure could be performed.
Results: :
The approach to the medial rectus muscle of the patients was possible with this tecnique, that is routinely used in orbital surgeries, with acceptable esthetic results.
Conclusions: :
Transcaruncular anterior orbitotomy is an alternative technique that may be used in patients with great angle esotropia, when it is not possible to perform a medial limbal access.
