Intractable diplopia after overcorrection of vertical strabismus

Diplopia after Strabismus Surgery

Diplopia is a disappointing and, at times, unanticipated consequence of what might otherwise be considered anatomically successful strabismus surgery. In this study, we review the existing literature regarding diplopia after strabismus surgery in the context of the senior author's experience. We divide postoperative diplopia types into cases that occur in the setting of normal binocular vision (or "normal" suppression) vs. cases that are the consequence of rare or anomalous sensorial adaptations. We then discuss how to identify patients at greatest risk based on history and preoperative testing, and we offer strategies for managing these sometimes-challenging cases.

Complications of strabismus surgery: incidence and risk factors

PURPOSE

To perform a systematic review of the complications of strabismus surgery, focusing on incidence and risk factors.

MATERIAL AND METHODS

A systematic literature search was performed using the Medline and Cochrane databases.

RESULTS

Local complications, such as conjunctival injection and mild scarring, are almost universal but only rarely have long-term clinical significance. There are several important complications that are uncommon but associated with significant long-term sequelae, including slipped muscles, lost muscles, stretched scars, incarcerated muscles, pulled-in-two syndrome, periocular infections, orbital cellulitis, scleral perforations, retinal detachments, endophthalmitis, anterior segment ischemia, and surgical errors.

DISCUSSION

Strabismus surgery is associated with a number of common and serious complications, and it is important for both surgeons and patients to be aware of the risks.
