Different Rates and Amounts of Vision Function Recovery During Orthoptic Therapy in an Older Strabismic Amblyope

Abstract

Orthoptic therapy was instituted in an 11-year-old patient having deep amblyopia, constant small-angle esotropia with anomalous retinal correspondence, and a past history of minimal success with such therapy. This combination of factors pointed toward a poor prognosis for substantial recovery of vision function. Rate of recovery of several monocular and binocular vision functions was monitored during the course of 18 months of intensive orthoptic therapy. Results showed marked improvement in several monocular vision functions, suggesting presence of considerable residual neural plasticity of multiple sites in the visual pathways of this older amblyope.

Fluctuations in accommodation: a review

“…Otto and Safra, 1975;Ciuffreda and Rumpf, 1985). The magnitude of the slope of the response/stimulus curve is lower than for normal subjects under the same observing conditions (Wood and Tomlinson, 1975;Hunt et al, 1983;Hokoda and Ciuffreda, 1986). Little systematic attention has, however, been given to the stability of the response in such eyes.…”

Amblyopia, Accommodation and Colour*

“…particularly the large steady-state error. Reduced amplitude of accommodation for age (Wood and Tomlinson, 1975) and a stimulusiresponse curve of a lower slope magnitude than observed in normal eyes (Mann, 1975;Wood and Tomlinson, 1975;Hung et ul., 19S3;Hokoda and Ciuffreda, 1986), have been reported in amblyopia. The usefulness of colour in eliciting a response in amblyopic eyes is unclear and little is known in general of the dynamics and stability of the response.…”
