The LANG STEREOTEST® I-R represents the current gold standard for random-dot stereotests, requiring no 3D glasses and offering high sensitivity and specificity for stereopsis. It displays three stereograms with disparities of 1200, 600, and 400 arcsec.\u003cbr\u003e\u003c\/strong\u003eThis test, designed to facilitate the examination of stereoscopic vision in children, is based on two principles: random dots and a grid of parallel cylindrical lenses.\u003cbr\u003eIn monocular vision, these stereograms reveal no outlines, whereas in binocular vision, the areas that produce horizontal disparity are seen in relief.\u003cbr\u003eThe examination combines random dots and a lens grid and is designed for rapid binocular vision screening across all age groups, including very young children. The card is presented at reading distance and the patient is asked what they see, while eye movements are observed.\u003c\/p\u003e\n\u003cp\u003eGiven that the test is most often performed on children, object shapes that are usually well-known from an early age have been chosen.\u003cbr\u003eThe three objects (cat, star, and car), all visible only stereoscopically with both eyes, are seen on different planes: the cat appears closer to the observer and the car further away. Children usually pass the test more easily than adults, for whom initial presbyopia, combined with convergence insufficiency, can cause difficulties.\u003c\/p\u003e\n\u003cp\u003eMDR 2017\/745 compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications:\u003c\/strong\u003e\u003cbr\u003eThe examination can be performed after the first year of age\u003cbr\u003eEvaluates the direct and consensual pupillary light reflex\u003c\/p\u003e","brand":"Gima","offers":[{"title":"Default Title","offer_id":49811014025552,"sku":"DG14080","price":350.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0866\/3996\/8592\/files\/31312.jpg?v=1740021997","url":"https:\/\/www.cfs.it\/en\/products\/stereotest-lang-i-r","provider":"CFS Prodotti Medicali s.r.l.","version":"1.0","type":"link"}
