[The effect of rapid alternating eye covering on formation of binocular vision in convergent squint treated with a localization method. I. Binocular vision examined in free space]. / Wplyw szybkiego naprzemiennego zaslaniania oczu na ksztaltowanie sie widzenia obuocznego u zezujacych leczonych metoda lokalizacyjna. Czesc I. Widzenie obuoczne badane w wolnej przestrzeni.

The authors have examined 35 children aged between 6 and 13 years. They were children with convergent fixed squint (angle: from +4 degrees to +26 degrees) with convergent fixation. The patients were treated in accordance with the localizing method -stage II/III. Visual acuity of the master eye was equal 1.0, and of the squinting eye-from 0.3 to 0.8 after correction. Children were practising 2 x 7-10 minutes for 5 days on an apparatus modelled on the Starkiewicz alteroobturator, looking straight forward and with eyes alternatively covered. They had the binocular vision at long and short distance checked with the use of a test with coloured filters (TF), classical Bagolini test (Bki). In all patients the subjective test was positive. Among 35 examined cases the tests for binocular vision did not change in 17. In 16 patients the image seen with the squinting eye came close to the one seen with the master eye by the average of 2.6 degrees at long distance and 4.3 degrees at short distance. Improvement took place after first exercise (8 children) or after all five exercises (8 children).

Evaluation based on the behavior of functional scotomas]. / Wplyw szybkiego naprzemiennego zaslaniania oczu na ksztaltowanie sie widzenia obuocznego u zezujacych leczonych metoda lokalizacyjna.

The authors have examined the behaviour of functional scotomas in the squinting eye in children treated on the static apparatus modelled after the Starkiewicz alteroobturator. They examined 25 children at the age of between 8 and 14 years with convergent squint with macular fixation. Visual acuity of the master eye was equal 1.0 and in the of the squinting eye from 0.4 do 0.8 in correction. The angle of squint was equal from +4 degrees to +26 degrees. The patients were treated in accordance with the localization method-stage II/III. Children were practising on the apparatus 2 x 7-10 minutes for 5 days. In 12 children out of the 25 under examination the functional scotomas were of the same size after exercises, and in 12 children it decreased from 12% to 40%, on average 24.8%. In 1 child the functional scotoma absolutely disappeared.

[Treatment of patients with small angle squint by exercising with Starkiewicz's tele-stereoscopy and synoptophore]. / Leczenie chorych z malym katem zeza cwiczeniami na telestereoskopie Starkiewicza i synoptoforze.

The authors examined 26 persons, 6-52 years old, with small angle squint (7 cases with esodeviation and 9 with exodeviation). The patients were treated according to localization method, stage II/III, their visual acuity was 0.6-1.0 with correction and they had normal binocular vision. During two weeks, for 10 to 15 minutes twice a day, they trained fusion using Starkiewicz's telestereoscope and synoptofor. In the group of patients with exodeviation, the range of fusion was increased on the average, by 3.6 degrees for long distance and 4.0 degrees for short distance. In these patients, prismatic correction was decreased on the average, by about 3.0 prism D. In the group of patients with esodeviation the range of fusion was increased on the average, by 1.5 degrees for long distance and 1.8 degrees for short distance. Prismatic correction was decreased on the average, by about 3.0 prism D.
