Titmus Stereogram For Binocular Stereopsis

The stereoscopic view of Titmus is divided into three parts

• The "fly" diagram with maximum 3000 "stereoacuity is used for qualitative examination of binocular stereopsis to judge whether there is binocular stereopsis function. Those with binocular stereopsis could see the fly floating on the reference surface obviously, while those without binocular stereopsis could not detect the fly floating;

  
  

• Three lines of 400 ~ 100 "stereoacuity" shape map ", each line has four shapes, one of which floats up. During the inspection, let the examinee point out that the shape is convex;

  
  

• Ten groups of 400 ~ 20 "stereos are diamond" circle "diagrams with sharpness. There are four circles in each group, and one of the four circles is different. After wearing polarizing glasses, it is perceived to float due to the parallax with different visual acuity, which is easy to be recognized by binocular stereopsis.

During the examination, it is necessary to wear polarized glasses and place the stereopsis Book 40 cm in front of the eyes. If the patient has ametropia, he should wear corrective glasses, and then wear the polarized glasses outside the corrective glasses
