purpose: to evaluate the effect of age on stereopsis. methods: we evaluated stereoacuity using tno and titmus test after full correction of refractive errors in  87 randomly selected subjects aged 5-80 years. results: there was a significant relashionship between stereopsis and age such that stereoacuity increased with aging (anova, p<0.001). conculsion: stereopsis decreases with aging and ther...

purpose : patients with infantile or childhood strabismus who do not achieve visual axes alignment early in life are believed to have poor prognosis with respect to the stereopsis. this study investigates the binocularity and stereopsis following delayed surgical alignment in patients with congenital and early-onset strabismus. patients & methods : 36 patients aged between 6-30 years participat...

INTRODUCTION The purpose of this study was to show to what extent developmental dyslexia influences a scope of stereoscopic. MATERIAL AND METHODS 176 pupils and students with developmental dyslexia were examined, including 52 girls and 124 boys aged between 8 and 19. Subjects were divided into three groups in respect of their age: I group 8-10 years, II group 10-14 years, III group 15-19 year...

people with whom he was speaking. Headaches and changes in concentration abilities resolved within 4 months, whereas visual symptoms still persisted after 8 months of drug abstinence, although slightly reduced in intensity. Neuro-ophthalmic evaluation, including visual acuity, visual fields, stereopsis using the Titmus test, colour perception, and pattern visually evoked response, failed to dem...

AIMS To examine the effect of a unilateral full thickness macular hole on sensory and motor binocular function and to study recovery after successful surgical closure. METHODS Twenty eight consecutive patients undergoing surgery for a unilateral macular hole underwent orthoptic examination, including measurements of Titmus and TNO stereoacuity and motor fusion range before surgery. Twenty thr...

AIM To determine the repeatability and agreement of stereoacuity measurements made using some of the most widely used clinical tests: Frisby, TNO, Randot and Titmus. METHODS Stereoacuity was measured in two different sessions separated by a time interval of at least 24h but no longer than 1wk in 74 subjects of mean age 20.6y using the four methods. The study participants were divided into two...

PURPOSE To assess the role of distance stereoacuity using the System Chart SC-1600 Pola (SC) to evaluate intermittent exotropia (IXT). METHODS Stereoacuity testing was performed in 28 children with IXT and 25 age-matched control subjects using the SC test, the distance Randot stereotest for distance, and the Titmus stereotest for near stereoacuity. Ocular alignment control was defined using t...

AIM To examine how stereoacuity changes with age as measured by a variety of stereotests. METHODS Stereoacuity has been measured in 60 normal subjects aged 17-83 years by a single observer using TNO, Titmus, Frisby near, and Frisby-Davis distance stereotests. Motor fusion was measured at (1/3) metre and 6 metres. RESULTS Overall stereoacuity measured by all tests showed a mild decline with ...

Journal of Behavioral Optometry Abstract Introduction: One factor in the evaluation of binocular vision is the measurement of stereopsis. Several methods are available for this purpose. The most common procedures are anaglyphic (with use of red-green filters) and vectographic (with use of polarized filters) procedures. The purpose of this study is the determination of stereopsis with local (Tit...
