AIM In strabismus clinics, stereoscopic depth perception is usually examined using static stimuli, but these stimuli do not necessarily allow assessment of the ability to perceive motion in depth. We assessed the ability to perceive motion-in-depth perception using a novel stereo motion test that we developed and compared with that to perceive static depth perception using a conventional stereo...

PURPOSE To evaluate the distance, intermediate and near visual acuity of patients with bilateral cataract operated on both eyes corrected for distance in one eye and for near in the fellow eye, as well as, their stereo acuity and their general satisfaction. SETTINGS Hospital de Olhos de São Paulo and Complexo Hospitalar Padre Bento - Guarulhos - São Paulo - Brazil. METHODS This is a prospec...

BACKGROUND The examination of depth perception with three-rods test, in addition to visual acuity testing, is required to obtain motor vehicle license to drive taxies and trucks, according to the Road Traffic Act in Japan. The aim of this study was to examine whether the results of the three-rods test would correlate with the results of static stereopsis tests, used in ophthalmic practice. ME...

Purpose: To develop stereoacuity test using a high-resolution 3D monitor and examined the effects of the monitor on the measured stereoacuity. Methods: We conducted stereoacuity test using a high-resolution 3D monitor. This 3D monitor can show parallax of 27 s (crossed) at the minimum at measurement distance 40 cm, and circularly polarized glasses were used for binocular separation. Titmus ster...

The purpose of this study was to evaluate the efficacy of amblyopia therapy utilizing a pair of rotating polarized filters to attenuate the light reaching the non amblyopic eye, and thus reduce its acuity, while still enabling binocular vision. Six amblyopic children between the ages 1 and 6 years were enrolled in the study. They were fitted with glasses that included a pair of polarizing filte...

Little is known about the localization in the brain of fusion of disparate images from each retina to create the sensation of stere­ opsis. One might expect the visual associa­ tion cortex in the parietal lobe to be in­ volved, but information about the effect of parietal lobe damage on stereopsis is scanty. Perhaps the most significant work con­ cerning the localization of stereopsis was that ...

PURPOSE To evaluate the effect of acrylic refractive prism and Fresnel membrane prism on stereoacuity in intermittent exotropia. MATERIALS AND METHODS Stereoacuities of fifty-two patients (mean age, 12.4 years; range 6 to 45 years) with intermittent exotropia were measured using the Titmus and TNO stereotests, while they wore prisms of varying power on nonfixating eye or evenly on each eye. ...

Background: This study aims to assess the impact of preoperative deviation on surgical success and sensory function in infantile exotropia. Furthermore, effects late timing these patients.Materials Methods: retrospective evaluated 16 subjects with exotropia that underwent management between 2012 2018. Patients ≤ 50 prism diopters (PD) were added Group 1, > PD 2 function. The is descri-be...
