[Computer treatment of strabismus and amblyopia using random-dot stereograms]. / Komp'iuternoe lechenie kosoglaziia i ambliopii s primeneniem sluchaino-tochechnykh stereogramm.

Application interactive CLASS software for stimulating productive binocular cooperation based on random-dot patterns and stereograms was used for treating strabismus and amblyopia in 105 children during a standard course of treatment. The children were divided into 3 groups treated by the CLASS alone (1), Class + two other application programs (2), and CLASS + traditional methods. General positive changes (improvement of visual acuity, decrease of eye deviation, etc.) were similar in these 3 groups. Positive effect of CLASS exercises on binocular visual mechanisms was significant. Due to precise evaluation of binocular interaction provided by CLASS, positive changes in binocular cooperation and stereovision were attained in 93% of children.

[Electric parameters of the L-type horizontal cell layer in the carp retina]. / Elektricheskie parametry sloia gorizontal'nykh kletok L-tipa v setchatke karpa.

The inner longitudinal resistance of the L-type horizontal cell syncytium in the carp retina ranges from 1.5 X 10(5) to 7,4 X 10(5) Ohm. The static resistance of the nonsynaptic membrane at the potential level corresponding to the bright light ranges from 2,5 X 10(3) to 19 X 10(3) Ohm . cm2 i.e. comparable with membrane resistances of many neurons recently investigated. Depolarization increases the resistance in 3,5 divided by 21 times up to 16 X 10(3) divided by 69.10(3) Ohm . cm2. Measured values of the capacity are 1 divided by 2 mcF . cm-2.

[Morphologic types of bipolar cells identified by regular grids of their axonal varicosities in the inner synaptic layer of the clupeid retina]. / Morfologicheskie tipy bipoliarnykh kletok, vyiavlennye po reguliarnym reshetkam utolshchenii ikh aksonov vo vnutrennem sinapticheskom sloe setchatki sel'devykh

A morphological structure of the inner plexiform layer in the acute vision area was studied in the retina of five Clupeidae species by a light microscope. It is shown that this layer is a three-dimensional regular grid formed by bulbous varicosities (synaptic complexes) of the axons of the bipolar cells. These varicosities arranged of different levels of the inner plexiform layer form mutually coordinated periodic grids differing in the orientation and periods. The analysis of this structure shows that not less than three types of bipolar cells take part in its organization.

[A microscopic study of the comparative morphology of the retina]. / Mikroskopicheskoe issledovanie sravnitel'noi morfologii setchatki

The cytoarchitecture layers and sublayers of the retina in pike, frog and cat are essentially different. The sublayers of internal granular layers 6a, 6b, 6c, 6d in these species differ qualitatively and quantitatively. The dendrites of ganglion cells and branches of amacrine cells are greatly laminated in the frog retina due to a complex stratification of the inner plexiform layer (about 10 sublayers). In all the vertebrates studied the ganglion cells are of two main types; symmetrical and asymmetrical with many variations. Asymmetrical amacrine cells are found in the pike and frog retina. The existence of vertical branches of amacrine cells in the outer plexiform layer in the cat retina is confirmed. The morphological features of the retina are discussed from the view point of physiological facts.
