Strabismus management

In this article, three topics of current interest in strabismus are covered. These include strabismus after glaucoma implant surgery, management of accommodative esotropia, and the timing of treatment for strabismic amblyopia. Glaucoma implants have improved our results with difficult glaucoma syndromes, however, a high incidence of postoperative strabismus has been associated with this procedure. The mechanism of the strabismus has not been clearly defined in previous literature, but in this article we describe three mechanisms that cause strabismus after glaucoma implant surgery and describe methods for managing this problem. The standard management of accommodative esotropia has historically resulted in a large number of undercorrections. Patients with accommodative esotropia have good fusion potential as the strabismus is acquired and binocular visual development occurred during the critical period. Recent studies indicate that we should increase our surgical numbers when managing patients with accommodative esotropia. Various treatment strategies are covered in the section on accommodative esotropia. Finally, a discussion on the management of strabismic amblyopia is presented. The importance of treating amblyopia first, then secondarily correcting the strabismus is emphasized.
