Optics Quiz 88 (step 3: the answer)

Optics Quiz 88 (step 3) ------------------------------------- A1) Name: TNO Stereotest Use: Tests stereopsis and suppression at near. The first three plates are used for screening (testing gross stereopsis). Plate IV: Tests suppression. If the right eye is suppressed, only two discs are seen (the middle one and the left one), and vice versa. In the presence of fusion (absence of suppression), 3 discs are seen using the red-green goggles. The last three quantitative plates test fine stereopsis (each plate has two level of testing: Plate V- 480 & 240, Plate VI- 120 &60, and Plate VII- 30 & 15 seconds of arc). A2) It requires red-green goggles (the green filter is placed in front of the right eye, and the red filter in front of the left eye.) A3) Advantages: 1. No monocular clues 2. The first three plates contain shapes that can be seen without stereoscopic vision - a butterfly (Plate I), two discs (Plate II), and a cross (Plate III). Therefore, they allow the examiner to assess the patient's understanding of the test. 3. Shapes that are visible only stereoscopically have match images on the opposite page, allowing the child to match rather than verbally name of the shapes. 4. Suppression test (Plate IV): Used to test fusion, detect suppression, and identify which eye is suppressed. https://share.google/NxNqClDJvTzla2eIC ...........................................
