Strabismus at children and its influence on function of binocular vision

Abstract

The purpose of this research is to examine functionality of binocular eyesight after surgery in case of esotropia as well as examine a size of strabismus angle, age, and their influence on strengthening of binocular eyesight after surgery in case of esotropia. The research covers 57 examinees with esotropia who underwent a surgery. Data used herein were collected on the basis of history data of examinees treated at Department for orthoptic and pleoptic of the Clinic for eye diseases, University Clinical Center Tuzla. Their age is from 3 to 14. The research includes three period of observation: first – initial examination, a period after surgery and a year after surgery. The examinees were divided into two age groups: 3-6 and 7-14. SPSS 17.0 for Windows program package was used for data processing applying analysis of a variant (ANOVA), i.e. p-value, hi-square test (dependence test). Upon completion of data processing, taking into consideration results obtained, it may be concluded that better results were reached at younger age examinees, aged 3-6, expressed in decrease of strabismus angle size and higher percentage presence of binocular eyesight a year after surgery, in comparison to age examinee 7-14. Research results indicate need for prompt treatment, early detection, i.e. early systematic examinations of preschool children and prevention of strabismus and amblyopia.

Cilj istraživanja je ispitivanje kvaliteta binokularnog vida postopera- tivno kod ezotropije. Ispitana je povezanost veličine ugla strabizma, uzrasta, blagovremenosti operativnog tretmana i kvaliteta binokularnog vida. Istra- živanjem je obuhvaćeno 57 ispitanika sa ezotropijom kod kojih je izvršen ope- rativni tretman. Podaci koji su korišteni za ovo istraživanje prikupljeni su iz istorija bolesti ispitanika, liječenih u Kabinetu za ortoptiku i pleoptiku Klinike za očne bolesti, Univerzitetskog kliničkog centra u Tuzli. Starost is- pitanika bila je u rasponu 3 do 14 godina. Istraživanje je obuhvatilo tri peri- oda posmatranja i to: inicijalni pregled, period posle operacije i godinu dana nakon operacije. Rezultati istraživanja ukazuju na potrebu blagovremenog tret- mana, rane detekcije, odnosno, ranih sistematskih pregleda dece predškolskog uzrasta i prevencie strabizma i ambliopije.
