New Surgical Method for Nystagmus without Null Point

Abstract

We report our results in nystagmus without null point surgery, utilizing a new technique consisting in the placement of a silicone encircling band around the globe over the four recti muscles, in the retroequatorial position. This method was tried only in nystagmus without null point and with both horizontal and vertical movements. We have not observed any ischemic complication of the anterior segment nor any important variation of intraocular pressure probably because the silicone band was not tightened. Other advantages of this method are its reversibility (cutting the silicone band) and the possibility of combining it with recession-resection of recti muscles at the same or at a later date.

The Effect of Bilateral Horizontal Rectus Recession on Visual Acuity, Ocular Deviation or Head Posture in Patients with Nystagmus

“…[10][11][12][13][14][15][16][17][18][19] Reports on nystagmus surgery to decrease nystagmus amplitude and intensity are limited, and most of these procedures have been performed on patients without head posture. 2,28,29 Large recessions of the horizontal recti for nystagmus was first proposed by Bietti In the present study, 80% of our patients had a sensory etiology for their nystagmus, yet surgery had positive effects on their vision. Visual improvement of 2 lines or more was noted in 58.8% of our patients, which is comparable to Davis et al's 35 and Atilla et al's 36 reports.…”
