PURPOSE The aim of this study was to define the nature of functional visual loss in amblyopia and to identify those subjects whose amblyopia is chiefly due to one or more of the following deficits: abnormal contour interaction, abnormal eye movements, abnormal contrast perception, or positional uncertainty. METHODS Fifty amblyopic children with a mean age of 5.6+/-1.3 years were referred from...

One hundred and two patients with anisohypermetropic amblyopia without strabismus were studied. Microstrabismus was excluded by detailed orthoptic examinations including visuscopy and Cüppers' bifoveal correspondence test. Treatment consisted in wearing correcting glasses and part-time or full-time patching of the nonamblyopic eye. In patients with dense amblyopia patching of the amblyopic eye ...

the orthoptic department to think that it will still occur. In one other case there is no possibility of it occurring. Single binocular vision also occurred unexpectedly in two cosmetic cases after operation. As the conjunctiva was completely detached from the muscle before advancement or resection, and carefully, replaced in its original position afterwards, it is difficult to believe it has a...

A 5-year-old Caucasian girl with known Hurler-Scheie's syndrome (mucopolysaccharidosis) developed a right Brown's syndrome while under orthoptic review. There was no evidence of trauma or inflammation of the superior oblique tendon, trochlea, or surrounding tissues. The Brown's syndrome in this case may be due to shortening of the superior oblique tendon, associated with the shortening of long ...

SINCE contact lenses have been used for monocular conditions of impaired vision in which the eye is divergent, e.g., aphakia and corneal scars, it has been found that although vision could be improved the affected eye remained divergent. Some of these eyes, i.e. those with small degrees of divergence, attained single binocular vision with orthoptic treatment; others with larger angles had to be...
