Minimally Invasive Strabismus Surgery
Minimally invasive strabismus surgery provides a valuable option for our strabismus patients with small deviations, and offers an additional or alternative treatment option to the use of prism glasses. The techniques described below can be performed in the office under topical anesthesia, are less invasive than standard strabismus muscle surgeries, and preserve the integrity of the muscle insertion, presumably sparing the anterior ciliary vessels.

Central tenotomy. This minimally invasive procedure, developed by Dr. Wright, weakens rectus muscles slightly by cutting the central tendon. Central tenotomy is useful for correcting microhypertropias, and corrects 2 prism diopters (PD) for each vertical rectus muscle. The procedure can be done with topical anesthesia (AVI 5,424 kb)
Central plication. This minimally invasive procedure, developed by Dr. Wright, tightens the central aspect of a rectus muscle. It tightens the central muscle and preserves the anterior ciliary arteries. It corrects 6–8 prism diopters (PD) for a 4–5 mm central plication of a rectus muscle. It can be done under topical anesthesia (Ishita Anand, MD; video editor) (WMV 66,638 kb)
