AMBLYOPIA EX ANOPSIA, WITH CASE.

Flicker fusion frequency in amblyopia ex anopsia.

Amblyopia ex anopsia is characterized by a defect in visual acuity of one eye, beginning in infancy, often with strabismus. The amblyopia disappears upon occlusion of the dominant eye in children, but not readily in adults. Peripheral acuity and sensation remain normal in field and threshold studies. It is believed that the origin of the amblyopia is in the macular projection of the visual cort...

Amblyopia ex-anopsia (suppression amblyopia); a preliminary report of the more recent methods of treatment of amblyopia, especially when associated with eccentric fixation in cases of strabismus.

Centrally fixed flicker thresholds in amblyopia.

Theories as to the etiology of amblyopia (also called amblyopia ex anopsia, strabis­ mus amblyopia, and amblyopia without ophthalmoscopic signs) may roughly be divided into two groups depending upon whether the primary defect is postulated in the cere­ bral cortex or in the retina. Wald and Burian who are among the most lucid ad­ vocates of the former position described measurements on five cas...

Brown syndrome with severe amblyopia: a case report from Africa

Brown syndrome is a rare form of strabismus that is characterised by restriction of elevation of the eye in adduction. This is a case report of an eleven year old Nigerian girl who presented with a history of squint and poor vision. She had visual acuities of 6/24 and counting fingers in her right and left eyes respectively. There was a left hypotropia in the primary position of gaze with assoc...

Visual Acuity Thresholds in Amblyopes.

THE use of the visuscope in an amblyopic eye helps to determine the part of the retina used during uniocular fixation. However, it is also important to know from a clinical standpoint whether the fovea is inhibited through a peripheral or a central mechanism, and whether in a particular case, the resolving power of the rods or the cones is affected. Various authors have studied the behaviour of...
