Ocular Dominance Diagnoi and It Influence in Monoviion Original Reearch Article

Purpoe To analyze the repone of normal emmetropic ubject to different ocular dominance tet and to analyze the influence of thi repone in urgically induced monoviion. Deign A propective tudy of diagnotic accuracy wa carried out to analyze the different tet to determine ocular dominance, without a gold tandard tet. Method Nine different tet were carried out in a group of 51 emmetropic ubject to determine both motor and enory ocular dominance. For analyi, patient were divided into two group according to age. Normal ophthalmologic examination reult were the incluion requirement, with normal binocular viion and good tereoacuity. Reult A ignificant percentage of uncertain or ambiguou reult in all tet performed wa found, except in the hole-in-card and kaleidocope tet. When the tet were compared, two by two, the correlation or equivalence found wa low and wa much lower if tet were compared three by three. Concluion No clear ocular dominance wa found in mot tudied ubject; intead, there mut be a contant alternating balance between both eye in mot emmetropic peron, but not in thoe with pathologic feature. Thi fact would explain the great variability both between and within different kind of tet. Alo, it would etablih that the monoviion technique i well tolerated in mot patient, with unucceful reult only in thoe patient with trong or clear dominance. Conequently, it eem appropriate to evaluate patient’ dominance before monoviion urgery to exclude thoe individual with clear dominance.
