BACKGROUND/AIMS Racial variation in the pattern of strabismus is known, but few large scale studies on non-white populations are available. Furthermore, longitudinal change in this pattern within a local setting has not been well documented in the past. This study aims to support the clinical impression that exotropia is more common in Chinese patients, and that the proportion of patients with ...

INTRODUCTION Identical twins account for 0.2% of the world population and 8% of all twins. A "mirror image" variation can be found in 25% of identical twins. Studies of twins assume a special place in human genetics due to the possibility of comparing genetic and other factors. We present two pairs of identical male twins with mirror-image astigmatism and esotropia. CASE OUTLINE The first was...

We report a case of acute comitant esotropia in a child with a cerebellar tumor. A 3-year-old boy was referred for management of a 9 month history of acute acquired comitant esotropia. On first presentation, the patient's angle of esodeviation was 50 prism-diopters (PD) at distance and near fixation without any lateral incomitance. The cycloplegic refraction revealed +0.75 diopters in both eyes...

BACKGROUND Strabismus surgery for congenital esotropia can be complicated by the development of a postoperative head tilt. PURPOSE To determine the pathophysiology of acquired head tilting following horizontal realignment of the eyes in children with congenital esotropia. MATERIALS AND METHODS Retrospective analysis of nine children with congenital esotropia who developed unexplained head t...

Purpose: To ascertain an examination interval that will not increase the risk of untimely detection of decompensation of accommodative esotropia whether or not initial nonoperative treatment must be supplemented. Methods: The records of 63 patients with controlled accommodative esotropia examined at 3to 6-month intervals were reviewed for age at first control, the occurrence of decompensation, ...

Results: The study period was from January 1992 to September 2003. Fifty-two patients were included in the study group. The pre-operative angle of deviation ranged from 50∆–85∆. Patient ages ranged from 15 months to 22 years, with a mean of 5.3 years and a median of 4 years. The gender distribution was 42% male (n = 20) and 58% female (n = 28). Surgery was successful (within 10∆ of orthophoria)...

BACKGROUND This is a retrospective study to determine the outcomes of the surgical correction in long-standing infantile esotropia with cross fixation. METHODS Medical charts of a group of patients with esotropia who had cross fixation and underwent surgery for strabismus between January 1991 and December 2004 were reviewed. The mean follow-up time was 4.7 years. Binocularity was measured by ...

Appropriate use of base-out prisms may be useful objective test for detecting persistence of normal binocular vision (4-dioptre prism test). By prolonged observation of prismatic correction of an esotropic patient one may infer the presence of an anomalous sensorial status. This can be done when the prismatic correction is compensated for by an increase of the angle of esotropia (prism adaptati...

Objective: Aim of this study was to evaluate possible risk factors affecting stereopsis in patients with refractive accommodative esotropia (RAE). Materials and Methods: The retrospective investigation performed on the records children RAE. Two groups were made according presence stereopsis. presumed onset age RAE, at initial correction, mean best-corrected visual acuity (BCVA), angle deviation...

Dr. Wagner has no financial or proprietary interest in the materials presented herein. doi:10.3928/01913913-20180212-01 What is the preferred deviation in the immediate postoperative period following surgery for infantile esotropia? This is a difficult question to answer, although many have tried. It is clear that the initial deviation may not be stable and may continue to change during the yea...
