Stereoacuity at distance and near.
PURPOSE Because previous studies have reported conflicting evidence, we examined a possible difference in stereoacuity between distance and near, in particular using a random-dot display. We compared distance and near stereoacuities using identical presentation formats at the two distances. METHODS Twelve young adults with low, stable refractive errors and apparently normal binocular vision p...
متن کاملImprovement in distance stereoacuity following surgery for intermittent exotropia.
PURPOSE To evaluate whether distance stereoacuity improves following surgery for intermittent exotropia using the Frisby Davis Distance (FD2) and Distance Randot stereotests. METHODS Eighteen patients (median age, 24 years; range, 5 to 68 years) with intermittent exotropia were prospectively enrolled. Stereoacuity was measured pre- and 6 weeks postoperatively using the FD2 and Frisby near tes...
متن کاملFrisby Davis distance stereoacuity values in visually normal children.
AIMS To establish the range of normal distance stereoacuity in young children using the Frisby Davis distance stereo test (FD2). METHODS Children passing preschool vision screening assessments underwent measurement of distance stereoacuity with the FD2 using a standard testing protocol. RESULTS 59 visually normal children aged between 36 months and 68 months were recruited to this study. Al...

Backgrounds and Objective: Stereoacuity is due to a relative difference between images because of retinal disparity. Measurment of stereoacuity is important for diagnosis and treatment of binocular anomalies and noerological problems. The aim of this study was to determine the effect of induced heterophoria by base-out and base-in prisms on distance stereopsis by the Three Needle Test. Material...
متن کاملeffect of induced heterophoria on distance stereoacuity by using the howard-dolman test
purpose : to evaluate the effect of induced esophoria and exophoria on distance stereoacuity at 6 meters methods : fifty subjects with distance corrected or uncorrected visual acuity of 6/6 and orthophoria without history of amblyopia, strabismus or any ocular pathology were recruited and distance stereoacuity was measured by howard-dolman test before and after introducing 2, 4, 6 and 8δ base i...
