AIM To investigate the postoperative eye alignment and binocular visual function after early surgery for infantile esotropia. METHODS Both the postoperative eye position and stereopsis were reviewed using the Titmus stereo test in nine patients who received uniocular medial rectus recession and lateral rectus resection under general anaesthesia before 8 months of age and were followed up for ...

AIM To discuss the long-term postoperative results of bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus resection (RR) in therapy of intermittent exotropia. METHODS We retrospectively analyzed 213 cases of intermittent exotropia who underwent surgery between 2008 and 2010. The patients were grouped into BLR group and RR group. Motor outcomes were d...

Aims. Increasing evidence shows that imbalanced suppressive drive prior to binocular combination may be the key factor in amblyopia. We described a novel binocular approach, interocular shift of visual attention (ISVA), for treatment of amblyopia in adult patients. Methods. Visual stimuli were presented anaglyphically on a computer screen. A square target resembling Landolt C had 2 openings, on...

PURPOSE To identify the characteristics of adult patients who develop acute concomitant esotropia of adulthood. DESIGN Retrospective noncomparative case series. PARTICIPANTS Ten patients were included in this study. INTERVENTION The charts of all adults with acute-onset concomitant esotropia who were examined at our institute between 1990 and 1997 were reviewed, and those who had develope...

We congratulate Yu et al. for their successful results where they evaluated the pattern distribution and the changes of strabismus surgery in pediatric population [1]. The authors observed that surgery for childhood exotropia was more common than surgery for esotropia in China and they stated that strabismus type and onset age were found to be associated with binocular function for subjects wit...

purpose: to determine the effect of occluding a normal eye on visual acuity, contrast sensitivity and stereopsis in amblyopic school children. methods: amblyopic children from primary schools of region 2 in mashhad were identified and referred to optometry clinics of mashhad medical university through a screening program. informed consent was obtained from the parents. all subjects underwent an...

Sir, Many patients on chronic haemodialysis (HD) suffer from chronic eye diseases, and the interaction of these diseases with the dialysis procedure can lead to worsening of vision [1]. Different studies have emphasized the effect of HD on visual acuity (VA), ocular surface disorders and tear function changes, fundus changes, VEP parameters, visual field findings and contrast sensitivity [2–5]....

Although the fact of orientation anisotropy is well established, its incidence has not been documented, as far as we are aware. Two earlier studies of anisotropy [H. Leibowitz, N. A. Myers, D. A. Grant, J. Opt. Soc. Am. 45, 76 (1955); J. C. Ogilvie and M. M. Taylor, ibid. 49, 898 (195...

PURPOSE To compare four stereo tests (Lang I, Lang II, Titmus, and TNO) and assess their effectiveness. The main focus of this study is to identify the most useful stereo test as a challenging tool in the screening of strabismus. PATIENTS AND METHODS A total of 143 Caucasian subjects, 74 males (52%) and 69 females (48%), aged between 4 years and 78 years (mean age 19.09±15.12 years) were exam...

PURPOSE To assess, among children with low literacy and poor stereoacuity, the efficacy of two intervention programs on child vision and education compared to a control program. METHODS Eighty-eight children aged 8 to 13 years who had reading problems, and demonstrated poor stereoacuity as measured by the Titmus stereocircle test (> 100 seconds arc) or computerized assessment were randomized ...
