Mērķis: izpētīt binokulārās sadarbības ietekmi pie dažādām ambliopijas dziļuma pakāpēm, izmantojot šķidro kristālu brilles.
Subjekti: pētījumā piedalījās 4 cilvēki, kur vienam subjektam bija zemas pakāpes (R.A. ambliopajā acī 0.2) un 3 subjektiem vidējas pakāpes (R.A. ambliopajā acī 0.5 un 0.6) ambliopija. Pētījuma dalībniekiem vecums ir robežās no 22 līdz 35 gadi (vidējais vecums ir 28.5 ± 6,9 gadi).
Metodes: tika izveidoti un pielāgoti stimuli, kas papildina jau esošo datorprogrammu un šķidro kristālu brilles. Šķidro kristālu brilles kalpo kā slēdži katrai acij neatkarīgi un ļauj pētīt binokulārās sadarbības procesus. Reakcijas laiks un pareizo atbilžu lielums (daudzums) ir tie dati, kas tika iegūti un analizēti visiem pētījuma dalībniekiem.
Rezultāti: iegūtie rezultāti, apstrādājot datus un veidojot grafikus, norāda uz to, ka tomēr katram indivīdam ir savs efektīvākais impulsa garums un latences lielums. Nav viena konkrēta skaitļa, kas būtu raksturīgs visai populācijai. Bet svarīgi, ka tika novērots uzlabojums eksperimenta beigās.
Secinājumi: subjektam ar R.A. 0.2 garāks impulss uzlabo stimulu atpazīšanu, nekā subjektiem ar R.A. 0.5-0.6. ŠKB var izmantot ambliopijas pētījumiem un kā rāda mūsu pieredze, iespējams, arī ambliopijas treniņiem.

The bachelor paper is written in Latvian and its length is of 43 pages, including 38 pictures, 4 tables and 18 source references. Aim: to investigate the influence of binocular interaction for different depth of amblyopia with the use of liquid Crystal Glasses (LCG). Subjects: 4 people participated in the research, one subject had low level (VA in amblyopic eye 0.2) and 3 subjects had media level (VA amblyopic eye 0.5 and 0.6) amblyopia. The participants’ age is between 22 and 35 (the average age- 28.5 ± 6, 9 years). Methods: there were used and adapted stimulus that supplements with the existing computer program and LCG. LCG shutter as independent switches for each eye and it allows investigating binocular interaction processes. The reaction time and the length (number) or the correct answers are those data that were achieved and analyzed for all participants. Results: the results due to data process and diagrams made point out that each individual has his own most effective length of impulse and latency rate. There is no particular number that would characterize the entire population. But it is important that at the end of experiment there was an improvement observed. Conclusions: the longer impulse for the subject with VA 0.2 improves stimulus recognition contrary to subjects with VA 0,5 - 0,6. LCG can be used for amblyopia studies and according to our experience it is possible to use it for amblyopia practice, too. Keywords: amblyopia in adult, binocular interaction, neurology of amblyopia, ferroelectric liquid crystal glasses, ocular dominance
