[On a binocular vision testing in concomitant strabismus].

Character of vision in 105 children with strabismus (with regular eye position) was tested using four dot test on different distance (5.0, 2.5, 1.

[Visual illusions].

The paper describes the principle of developing a stereoscopic illusion test based on color anaglyphs. The test demonstrated on a monitor screen contains images of anaglyphic figures that are uniform in size and shape. Illusion is that, by defining the arrangement of the figures from their distance, an observer perceives them uniform.

[The role of rotary prisms and dynamic color stimuli in binocular vision recovery in children with squint].

A modified procedure for diploid treatment is proposed to disinhibit a functional scotoma and to develop binocular vision (BV) in children with squint. The procedure is to examine a special test object through rotary prisms and polaroid filters inserted into a modernized spectacle frame. During treatment there is an opportunity of simultaneously changing the color of the test object and the position of its image on the retina.

[Study of stereoscopic visual acuity, by using the color anaglyph method].

A method is proposed to study stereoscopic visual acuity (SVA) by means of the test objects designed by the computer program Adobe Photoshop CS 2 (version 9, 2005). Each test object contains 3-4 silhouette figures made on the principle of color anaglyphs with varying degrees of transverse disparity. The capacity of an examinee of correctly showing on the display screen the sequence of the layout for the figures in depth with a minimal disparity determines its SVA.

[New method of visual fields color division in diploptic treatment of strabismus].

A new method of color division of the visual fields based on polarized light interference is described. A new method for diploptic therapy of strabismus is developed, based on the above principle and possessing numerous advantages. The method was used in 38 patients with binocular disorders of various severity; binocular function improved in 18.
