Eccentric fixation measurements using visuoscopy and Macula Integrity Tester (MIT) in children with amblyopia

subject

description

The aim of the work was to compare measurements of eccentric fixation in children with amblyopia using two different methods, a traditional visuoscopy and MIT. Monocular fixation was evaluated using visuoscopy and MIT in 16 patients (from 5 to 9 years old). Measurements were started with the better seeing eye to compare the results obtained with the amblyopic eye. All study participants were selected with anisometropic and refractive amblyopia. Visuoscopy is simpler than MIT and less dependent on patient responses, so visioscopy can be used for young children who have not yet acquired verbal skills. Children over the age of 5 can more easily understand the MIT method and get more reliable results. By determining the visual acuity and fixation point, it is possible to determine the maximum visual acuity achievable with an appropriate fixation. The MIT and visuoscopy methods complement each other, both of which can be used to identify the fixation point. In Latvia, amblyopia treatment is carefully performed in various vision institutions, but assessment of eccentric fixation is very rare. Evaluation of eccentric fixation can help predict the outcome and treatment progression of amblyopia.
