description

Anotācija. Darba mērķis ir izpētīt verģences atbildes dinamiskās īpašības un pārbaudīt, cik lielā mērā šīs īpašības kopā ar citiem fizioloģiskiem mehānismiem ir saistītas ar fiksācijas disparitātes izveidošanos. Mērījumi veikti subjektīvi, izmantojot nonius metodi, un objektīvi, izmantojot videookulogrāfu EyeLink II. Verģences atbildes asimetrijas individuālās atšķirības spēj izskaidrot ne vairāk kā 50 % no fiksācijas disparitātēm. Fiksācijas disparitātes izveides process ir saistīts arī ar tumsas verģenci un metodes kļūdu, kā arī ar akomodācijas darbību. Līdz ar to var secināt, ka klīniski nozīmīga fiksācijas disparitāte, kas noteikta, izmantojot subjektīvas metodes, parādās atšķirīgu fizioloģisku procesu un metodes kļūdas kombinācijas rezultātā. Atslēgas vārdi: Fiksācijas disparitāte, verģence, tumsas verģence, heteroforija
