The sensitive period: transfer of fixation after occlusion for strabismic amblyopia.

The sensitive period: transfer of fixation after occlusion for strabismic amblyopia.

Of 2649 patients with strabismic amblyopia who attended clinics between 1941 and 1978, 1904 patients were reviewed. Of these, 115 patients had transfer of fixation after occlusion. These were analysed according to the type of transfer of fixation and relation to occlusion and age. The period of maximum sensitivity to short periods of occlusion extended to 18 months, declining to about 30 months...

Reliability of Fixation Preference for Detecting Amblyopia in Strabismic Patients

PURPOSE To evaluate the association between fixation preference (FP) and amblyopia in strabismic patients. METHODS This study includes 50 patients with horizontal, vertical or mixed strabismus of at least 10 prism diopters. Best-corrected monocular visual acuity (VA) was measured using Snellen E-chart and the presence of amblyopia was determined accordingly; FP was evaluated and graded from 0...

On the relationship between strabismic amblyopia and eccentric fixation.

Landolt C and grating acuity are compared with that normally expected of the eccentric fixation region for 10 strabismic amblyopes. The findings suggest that 2 populations of amblyopes exist. For some amblyopes visual function is that predicted of the eccentric region used for fixation, whereas for other amblyopes there is a further pathological reduction in visual function. These findings may ...

Strabismic amblyopia.

NOTWITHSTANDING the vast literature, a complete and satisfactory definition of the clinical picture of amblyopia in strabismus has not yet been produced, and some symptoms are often confused with those of other forms of functional amblyopia. Bangerter (1953) and many other authors embrace in the term " amblyopia ex anopsia" the amblyopia observed in anisometropia, in high ametropia, and in nyst...
