+2-00 to +2-75 dioptres of spherical hypermetropia in the more emmetropic of a pair of eyes is significantly associated with esotropia (P less than 0-001) and the presence of amblyopia (P less than 0-01). Anisometropia is not significantly associated with esotropia (P = 0-31) unless there is spherical hypermetropia of +2-00 dioptres or more in the more emmetropic eye (P less than 0-001). Hyperm...

At birth a baby’s vision is very immature, with an acuity of around 3/601,2. Visual experience in infancy and childhood has a major influence on the development of the visual pathways, particularly the visual cortex3,4. During the critical periods of visual development visual acuity develops as do other modalities such as contrast sensitivity, colour, pattern and motion perception, and binocula...

The Early vs. Late Infantile Strabismus Surgery Study Group is a group of strabismologists and orthoptists from 58 clinics in 11 European countries. They investigate whether early or late surgery is preferable in infantile strabismus, in a non-randomized, prospective, multi-center trial.(1) Infants between 6 and 18 months of age receive a standardized entry examination and are then operated eit...

AIM To determine whether there has been a consistent change across countries and healthcare systems in the frequency of strabismus surgery in children over the past decade. METHODS Retrospective analysis of data on all strabismus surgery performed in NHS hospitals in England and Wales, on children aged 0-16 years between 1989 and 2000, and between 1994 and 2000 in Ontario (Canada) hospitals. ...

INTRODUCTION In esotropia with larger angles > near than at distance, splitting of the medial rectus muscle has been suggested as a treatment option. Previous reports of bilateral medial rectus Y-splitting as a first intervention showed a reduction of the distance/near disparity with fewer side effects compared to posterior fixation surgery. We address whether a medial rectus Y-splitting as a s...
