  2. Titmus Vision Screener PROFESSIONAL Basic Testing Information: Each model contains 8 test slides. Tests are administered at Far, Near and Intermediate distances. For ease in administration, follow test sequence under each category. If you wish to skip a test, continue with the next test in the sequence. Slide & Testing Function CLICK ON SLIDE IMAGE TO LEARN HOW TO DO THE TEST. Slide 1 SA-APS-1 Allen Picture Test Slide 2 SAS-2 Acuity Right & Left Eye Slide 3 SPS-3 Heterophorias Slide 4 SCD-1 Color Percetion Slide 5 SA-BRL-4 Visual Acuity Slide 6 SLP-1 Lateral Phoria Slide 7 SVP-1 Vertical Phoria Slide 8 SA-BRL-2A Visual Acuity

  3. Allen Picture Test Slide – SA-APS-1 Testing distance Age tested This is the Allen Picture Test. It test visual acuity (sharpness of the eye) and binocularity (both eyes working together). Test is administered at FAR for both eyes (binocularity), Right and Left Eye (acuity). Can test as young as 3 ½ years. TESTING FUNCTION Binocularity: On top line, what objects do you see? Acuity: What objects do you see on line….? PATIENT QUESTION Binocularity (20/100) Jeep, Telephone, Cake, and Horseman Acuity Right Eye PATIENT ANSWER Acuity Left Eye Binocularity: PASS - All Images Seen FAIL - Two Images Seen Acuity, Right or Left Eye: PASS - 20/30 & 20/40 FAIL - 20/50 PASS/FAIL CRITERIA Review pictures of Jeep, Telephone, Birthday Cake and Horseman with children before testing for better communication. TIPS Binocularity: Test both eyes together (do not occlude) Acuity, Right Eye: Occlude Left Eye Acuity, Left Eye: Occlude Right Eye BACK TO MAIN

  5. Acuity, Both Eyes Slide – SAS-2 Testing distance Age tested Tests visual acuity (sharpness of the eye.) Right and Left Eye images are different. Administer test at FAR and using PLUS Lenses. Refer to page 4 for Plus Lens Test. TESTING FUNCTION Which direction is the “E” (are the table legs) pointing? Top, Bottom, Left or Right? When using Plus Lens, ask child to read 20/20 Line. PATIENT QUESTION Right Eye Left Eye PATIENT ANSWER For Blue, Red, Yellow & Green Lines, PASS – Ability to identify 4 out of 6 “E”’s on each line. With Plus Lens, FAIL if child can read 20/20 Line. PASS/FAIL CRITERIA Ask the child to read the Pilot Line, starting with the big “E” at the Left. The pilot line is an indication of the visual acuity of the child, confirm this by asking the child to read the corresponding visual acuity line. Describe the “E” as “table with legs”, if needed and have child indicate direction of “legs”. TIPS BACK TO MAIN

  7. Muscle Balance Slide – SPS-3 Testing distance Age tested This is a Muscle Balance Test to test Vertical and lateral Phoria in children. For children that fail this test, it helps identify if there is a possibility of amblyopia (lazy eye) or strabismus (squint eyes). Test is administered first at far and then at near. TESTING FUNCTION PATIENT QUESTION Is the red ball in Box A, Box B or the ground? Box A, Box B or the ground. PATIENT ANSWER FAR: Ball in Box A is PASS, anywhere else is FAIL NEAR: Ball in Box A or Box B is Pass, anywhere else is FAIL. PASS/FAIL CRITERIA Occlude Left Eye and tell the child that you will throw a red ball and it should land in a “sandbox”. Then open the Left Eye and ask the question. Encourage a quick response because the “ball” will tend to “move” after a few seconds. If necessary, repeat the test. TIPS BACK TO MAIN

  9. Color Perception Slide – SCD-1 Testing distance Age tested Test red/green color perception. Test uses accurately reproduced Ishihara Pseudo-Isochromatic plates does not classify type or degree of severity. TESTING FUNCTION What numbers do you see in circles A, B, C, etc.? PATIENT QUESTION C A B D E F PATIENT ANSWER 5 26 12 6 16 A total of 8 numerals should be seen: 1 2 5 2 6 6 1 6 – “nothing” or “no number” in circle F is a correct response. PASS/FAIL CRITERIA Normal: Correct reading of ALL 8 numerlas Mild Deficiency: Correct reading of at least 5 numerlas FAIL: Inability to read at least 5 numerlas Individuals with 20/50 or less in both eyes may FAIL this test due to low acuity rather than deficiency. NOTE: To avoid memorization of numbers in circles, ask subject to respond randomly. (example, circle E, B, D, etc.) TIPS BACK TO MAIN

  11. Acuity, Both, Right & Left Eye Slide – SA-BRL-4 Testing distance Age tested This test checks for visual acuity of Both Eyes, Right Eye and Left Eye using the same slide. TESTING FUNCTION Do you see three columns of letters? Read line from left to right. Direction for each line: Both Eyes Test: Read the letters in the middle column Right Eye Test: Read the letters in the right column Left Eye Test: Read the letters in the left column PATIENT QUESTION PATIENT ANSWER For each column of letters: Lines 1 & 2 – All letters must be read correctly Lines 3 to 7 – Allow to miss any one letter in a column PASS/FAIL CRITERIA Start with the line the subject can see most clearly. Acuity levels may be different for each eye. You may use a different BRL test (like SA-BRL-2A) for NEAR to avoid memorization. Some individuals may have irregularities due to binocular vision problems: Right/Left column appears blurry, suppression of Right or Left Eye symbols, disappearance of symbols in left or right column, failure to fuse Right and Left Eye columns into three columns.

  13. Lateral Phoria Slide – SLP-1 Testing distance Age tested This is a Muscle Balance Test to define a value for the balance of the eyes in the horizontal direction. TESTING FUNCTION PATIENT QUESTION Do you see an arrow? The arrow points to which musical note? Laterall Phoria Key Notes on slide PATIENT ANSWER Prism Diopters LEFT Hyperphoria Prism Diopters RIGHT Hyperphoria Prism Values ORTHO PASS/FAIL CRITERIA Based on job standard selected. Occasionally, the subject may be confused. When this happens, momentarily occlude the Left Eye, which sees the red line. Ask the subject to respond immediately when the red line reappears. (Where do you first see the red line?) Remove occlusion. This is a binocular test. It should not be given to an individual with vision in only one eye. TIPS BACK TO MAIN

  15. Vertical Phoria Slide – SVP-1 Testing distance Age tested This is a muscle Balance Test to define a value for the balance of the eyes in Vertical direction. TESTING FUNCTION Do you see a red broken line: Through the round part of which musical note does the line pass PATIENT QUESTION Vertical Phoria key Notes on slide Prism Values PATIENT ANSWER Prism Diopters RIGHT Hyperphoria Prism Diopters LEFT Hyperphoria ORTHO PASS/FAIL CRITERIA Based on job standard selected. Occasionally, the subject may be confused. When this happens, momentarily occlude the Left Eye, which sees the red line. Ask the subject to respond immediately when the red line reappears. (Where do you first see the red line?) Remove occlusion. This is a binocular test. It should not be given to an individual with vision in only one eye. TIPS BACK TO MAIN

  19. Binocular Vision Slide – SF-1 Testing distance Age tested Test vision with Both Eyes working together TESTING FUNCTION How many cubes do you see? What are the colors of the cubes? PATIENT QUESTION PATIENT ANSWER Three, Red / White / Blue Three: PASS Four, then Three: PASS Four: FAIL, NO FUSION Two: FAIL VISION IN ONLY ONE EYE PASS/FAIL CRITERIA The 2 white cubes should fuse together for a subject with good binocular vision. The functioning eye can be determined by asking the subject to identify the colors. TIPS BACK TO MAIN

  21. Color Perception Slide – SPCD - 1 Testing distance Age tested Test color perception. Test uses photographically reproduced TITMUS Pseudo-Isochromatic blocks. TESTING FUNCTION In the boxes, which direction is the “E” (table legs) pointing? Top, Bottom, Left or Right? With preschool/primary grade children follow sequence as – Blocks 1,4,5,6,7,8 and then Blocks 2,3 since these are the most difficult. PATIENT QUESTION PATIENT ANSWER Unconditional PASS: Correct reading of all blocks Conditional PASS: Correct reading of at least 5 blocks. FAIL: Inability to read at least 5 blocks Children who have a Conditional PASS in the second or lower grades may PASS when tested again in the higher grades PASS/FAIL CRITERIA Block No. 1 is introductory. For children, it is assumed that they are familiar tihe the “E” and know how to respond, Individuals with low visual acuity (20/70 or less) in both eyes may FAIL this test, due to low acuity rather than faulty color perception. This screening test checks for a problem in recognizing colors but does not classify type or degree of severity. TIPS BACK TO MAIN
