A case of occlusion amblyopia resulting from occlusion of a twin strabismic amblyopia.

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...

Intensive occlusion therapy for amblyopia.

AIM To study the effects of supervised inpatient occlusion treatment for amblyopia in children who had failed to respond to outpatient treatment. METHODS A retrospective study of 39 children admitted to a paediatric ophthalmic ward for 5 days of supervised intensive occlusion therapy having previously failed to respond to outpatient occlusion. Visual acuity of amblyopic and fellow eyes was re...

EYcacy of occlusion for strabismic amblyopia: can an optimal duration be identified?

Background/aims—The study of occlusion eYcacy in amblyopia has been hampered by the use of non-logMAR acuity tests and a failure to assess threshold acuity for both eyes. These issues are addressed in the current study which compares the eVect of spectacles alone and spectacles in combination with occlusion, with the use of the logMAR crowded test. Methods—Changes in uniocular and interocular a...

The efficacy of occlusion for strabismic amblyopia. Can an optimal duration be identified?

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...
