Factors relating to visual acuity in children who have been treated for convergent squint.
نویسندگان
چکیده
Retrospective analysis of a selected sample of children who presented with convergent squint has shown that abnormal meridional hypermetropia (3.5 D or more) at age 1 was the principal factor associated with severe amblyopia (6/24 or less) remaining after conventional treatment. Neither the reported age of onset nor delay in presentation influenced the final visual outcome.

Update on squint and amblyopia.
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...
متن کاملSubnormal Binocular Vision with Special Reference to Peripheral Fusion* by T. Keith Lyle and Jill Foley
IN some cases of unilateral convergent squint the vision of the squinting eye may be suppressed to such an extent that eventually the affected eye appears to be almost blind through suppression-amblyopia, and the patient appears to rely almost entirely on one eye. On the other hand, in the case of a freely alternating squint, the visual acuity of each eye may remain normal throughout life, the ...

متن کاملThe Role of the Orthoptist in the Treatment of Squint
MANY people are aware that the old idea in the treatment of squinting children was to prescribe glasses as required, and then, if the appearance of the eyes did not improve, wait until at least fifteen or sixteen years of age before operating. This postponement of operation until early adult life was considered essential, so that it could be performed without general ana-sthesia, and with the c...
متن کاملThe Natural Course of Intermittent Exotropia over a 3-year Period and the Factors Predicting the Control Deterioration
The natural course of intermittent exotropia and the factors affecting its control has been unclear. We aim to report the natural course of our cohort of 117 Chinese children with intermittent exotropia and to identify baseline parameters that may have predictive value in the control deterioration of the disease. The visual acuity, spherical equivalent, compliance to orthoptic exercise, angle o...
