IMPORTANCE Binocular summation (BiS), or improvement in visual acuity using binocular vision compared with the better eye alone, is diminished in patients with strabismus. However, it is still not known how strabismus surgery affects BiS. OBJECTIVE To determine whether BiS improves after strabismus surgery. DESIGN, SETTING, AND PARTICIPANTS Prospective study of 97 patients undergoing strabi...

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...

Purpose To report the presenting signs of retinoblastoma in a large cohort patients who underwent orthoptic assessment at presentation. Methods A retrospective medical chart review was conducted on 131 with presented consecutively to single institution during 6-year period. The main outcome measure sign(s) disease. Results Of retinoblastoma, 88 unilateral disease and 43 bilateral (mean ages: 22...

Ocular movements were studied electro-oculographically in 10 normal subjects and 10 patients with alternating strabismus. Fixation and pursuit movements and to a less extent the saccadic movements were observed to be abnormal in patients with alternating strabismus. The defect in pursuit movements was shown to be statistically significant. There was no correlation between the extent of ocular m...

TEXT-BOOK examples ot strabismus fixus and of the retraction syndrome are not commonly encountered. Abnormal medial recti, however, showing some tendency towards the fibrosis or muscular thickening characteristic of such conditions, not uncommonly appear when ordinary squints are operated upon. Abnormal medial recti are usually found in congenital convergent squint. In most such cases there is ...

Strabismus can be distressing to our patients, yet often challenging to treat even in expe‐ rienced hands. The goal of this chapter is to clearly and concisely share with the reader strategies and strabismus surgical techniques in common horizontal and vertical strabis‐ mus, that will improve the care of our patients. We describe indications for strabismus surgery, how to plan for successful su...

Visual loss following strabismus is rare and usually follows inadvertent perforation of the globe at the time of surgery. Previous studies have reported that the incidence of this complication occurs in 8% to 12.1% of patients undergoing conventional strabismus surgery, and higher incidences have been reported for posterior fixation sutures. We conducted a prospective study to determine the inc...

Eight centres throughout the United Kingdom cooperated with a prospective evaluation of the accuracy of surgery for horizontal strabismus. The eight centres were divided into four with a specialist interest in strabismus and four offering a general ophthalmic service. Each participating surgeon was asked to indicate the anticipated outcome of surgery and, thereafter, orthoptic examinations were...
