Abstract
Binocular vision means both binocular single vision and vision in both eyes recognized as monovision, and visual acuity, anisometropia, and ocular deviation are involved in binocular vision. Therefore, binocular function test should be performed during the diagnosis and treatment of the strabismus, amblyopia, and aniseikonia. The binocular function test examines the stereopsis, fusion and suppression, and abnormality of retinal correspondence, to assess whether and how much the two eyes are integrated into single vision. Because the degree of dissociation of the two eyes differs according to the individual test, careful interpretation is required.

: The sensitivity of clinical measures of stereoacuity in the detection of interocular differences in retinal images was examined in 50 adults with normal binocularity. Interocular differences in retinal image size (aniseikonia), clarity (anisometropia) and brightness, as well as differences in absolute and relative pupil size (anisocoria) were created in small steps over a large range to determine their effect on threshold levels of stereopsis. Their effect on stereoacuity was measured in both ...

The Worth 4 Dot Test was introduced by Claude Worth in 1903 as a test measuring binocularity. Hardy, in 1937, incorporated the lights of Worth into a hand-held flashlight. Further modifications wer...

The attempts at treating anomalous correspondence by prisms in esotropia have led to the observation that frequently the angle of deviation increases with prismatic correction. The convergent movements induced by base-out prisms in esotropic patients resemble normal fusional movements in some aspects; they are provisorily called ‚Äėanomalous movements‚Äô and the objective differences between anomalous movements and normal fusional movements are reported.

Some concepts regarding suppression, anomalous correspondence and amblyopia are revised according to the sensorial findings obtainable from esotropic patients directly in casual seeing (with the aid of the striated glasses test) and by grading a sensorial dissociating effect (with the aid of a bar of optical filters). The following points are emphasized:

In the first part of the paper are considered various aspects of the binocular status with special regard to the development of areas of anomalous binocular vision in comitant strabismus. A possible unitary interpretation of these various aspects is given.

Summary A brief summary of the results of the test is simply that a prism, moved rapidly back and forth before an eye which is contributing to normal binocular vision and fusion, causes diplopia to be noted and produces little or no movement of either eye. The same is true over whichever eye the prism is placed. In amblyopia and strabismus, the prism moved in front of the sighting eye induces no diplopia but instead a to-and-fro movement of the image, and conjugate movement of the eyes; whereas ...
