[The effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees].

Purpose: This study assesses the effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees.

Material And Methods: The effect of the treatment in 35 children (35 eyes) with amblyopia of various degrees was evaluated using the MP-1 Microperimeter. The stability was determined by two criteria - number of fixation point hits in the 2° zone and the width of the field of fixation.

[The effect of pleoptic treatment on retinal light sensitivity and visual fixation in a patient with amblyopia of high degree and off-center fixation (case study)].

Most sources state that pleoptic treatment is ineffective after the age of 14 years. Despite the high level of diagnostic capabilities in modern ophthalmology, unilateral amblyopia is quite often diagnosed in adolescents. This rises the question - should they refuse treatment? To evaluate the impact of treatment on retinal light sensitivity and the state of the patient's visual fixation, a 23-year-old female patient with high degree amblyopia was examined using the MP-1 Microperimeter.

[Laser speckle-based method for binocular vision recovery in diploptic treatment of concomitant strabismus].

Objective: to investigate the effectiveness of the method of "dissociation" for concomitant strabismus treatment, which involves laser speckles and polaroid separation of visual fields.

Material And Methods: A total of 40 patients with different types of concomitant strabismus and the average age of 9.8 years were enrolled.

[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.

[Influence of virtual reality helmet on visual functions].

The authors studied influence of new computer device--video helmet--on visual functions of children, adolescents and adults.

[Effects of decreased nystagmus amplitude in children periodically exposed to light].

The effect of steady-state nystagmus suppression has been found upon periodic light exposure of the eye. The paper describes the exposure facility and procedure based on the changes in the amplitude and frequency of light pulse until there is a response of a patient's nystagmus parameters that are continuously monitored by video-assisted computer system. After periodic light exposures, there was a persistent suppression of nystagmus and a steady-state increase in visual acuity by an average of 0.

[Problems of oculomotor and binocular pathology].

The paper discusses the problems of abnormalities of the oculomotor apparatus and binocular vision, considers the topical aspects of the pathogenesis and treatment of amblyopia, gives data on the new methods of recording the binocular movements of the eye, and provides evidence for the tactics and stage sequence of surgical treatment for concomitant oculomotor disturbances.

[Clinical presentation, diagnosis and treatment of strabismus combined with ptosis].

On the basis of examination of 172 patients with strabismus concomitant with ptosis, different clinical forms of the former were defined and their clinical variations were classified. Symptomatology was described for each form. An independent type of false positive ptosis was pointed out.

[State of cyclofusion reserves in subjects with normal binocular vision].

The paper for the first time presents statistically processed data on the cyclofusion reserves of subjects with normal binocular vision (25) for different age groups: adolescents aged 12-14 and adults aged 18-35 years. Two types of tests for evaluating cyclofusion under conditions of haploscopy (sinoptophore) are offered. The results can be used as a criterion for evaluating cyclofusion in various oculomotor abnormalities: squint, diplopia, and cyclotropia.

[Use of liquid crystal eyeglasses for examination and recovery of binocular vision].

A new method for diploptic treatment of strabismus is proposed, based on phase division of visual fields using liquid crystal eyeglasses --computer complex. The method is based on stereovision training (allowing stereothreshold measurements up to 150 ang. sec.

[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.

[Method of treatment of amblyopia with dynamic color stimuli emerging in polarized light interference].

A method for treating amblyopia by using dynamic color objects (stimuli) influencing simultaneously different channels of the optic system is proposed. Original equipment based on polarized light interference was used, as well as a nomogram permitting rapid assessment of the optimal size of the offered test objects. The method was used in 90 children (99 amblyopic eyes).

[The possibility for using the phenomenon of polarized light interference in treating amblyopia].

A new method for treating amblyopia is proposed, making use of the phenomenon of polarized light interference. It helps act simultaneously on the brightness, contrast frequency, and color sensitivity in response to patterns. The method was used in the treatment of 36 children.

[Possibilities of the use of low-energy laser effects on the ciliary body in optic nystagmus].

The accommodation potential of the eye is markedly reduced in patients with optic nystagmus. Trans-scleral exposure of the ciliary body to infrared low-energy laser at wavelength 1.3 microns may be used to repair the accommodation potential of the eyes and improve the visual function in nystagmus.

[Clinical aspects of strabismus with insufficiency of the superior oblique muscle].

Clinical features of vertical strabismus with superior oblique muscle insufficiency were studied in 123 patients. A complex of clinical methods was used and clinical evaluation of these methods made. Various forms of strabismus with superior oblique muscle insufficiency were detected.

[The importance of using the computer in treating children with strabismus and amblyopia].

A method for therapy of strabismus and amblyopia with the use of IBM PC AT type computer is suggested. It consists in active interaction of a patient with various test objects on the monitor and is realized via a special set of programs. Clinical indications for the use of a new method are defined.

[Study of binocular vision by the binary metric method].

The authors describe a method for binocular vision studies with the use of spatial visual effects emerging when double images are fused in physiologic diplopia. Various forms of binocular cooperation were detected and a clinical classification of these forms developed, based on the ability to obtain a binocular visual image. One of the distinctions of the suggested method is the detection of not only binocular fusion, but of the ability to in-depth perception.
