The eyes are a person’s windows to the world. Without good vision one can experience a sense of helplessness and may even suffer in other skills necessary for a full and functional lifestyle.

Introduction

The Importance of Vision Screening

Utilizing the TITMUSiSeries vision screeners, you will quickly be capable of assessing whether a person’s vision is within the normal parameters. Visual abnormalities will be revealed, often motivating action for a referral for further visual examination and possibly a much-needed visual correction. Consequently, that person’s quality of life can be enhanced. The vision screener is capable of testing functions not determined by the typical “wall” or “eye” chart. Binocularity, muscle balance, color perception, acuity at near and far, color deficiency, depth perception, and a myriad of other visual functions can be screened. The wall chart screens for acuity only, leaving many visual abnormalities unidentified.

About the “TITMUS” TITMUS set the standard for vision screening instruments in 1959 with the introduction of the OV7 model vision screener. Often referred to as the “TITMUS,” the older OV7 model as well as the later-generation TITMUS Model 2 are still in use in many industrial locations, optical practices, as well as schools nationwide. The screeners are known for their durability. As the market leader, TITMUS has developed the new TITMUSiSeries of vision screeners. Designed to meet the unique needs of the 21st century, the TITMUSiSeries will be a welcome tool because of its convenience, accuracy, and versatility.

Preparation for Testing

Preparation for Testing 1. Place the instrument on a table of conventional height with sufficient top area to permit test administrator to manipulate controls and record results. 2. Unlock handle, bottom lock and raise instrument as indicated in section, Unpacking the Instrument. 3. Connect panel to instrument as shown using panel cord. Hold the connector with flat side down, to plug into panel and instrument. TITMUSi400 only Panel cord, length 0.876 meters.

4. Connect power cord to instrument and turn switch ON. Power cord (3pin length 3 meters).

5. Test all membrane switches to ensure proper operation. 6. Check lenses to ensure they are clean. Use cleaning towlettes or fog cloths (if lens are fogging). 7. Place record forms and other accessories near the instrument, ready for use. 8. Avoid positioning the instrument where strong glaring light will shine directly into the instrument or into the subject’s face. 9. The patient should be seated comfortably. See section on Patient Positioning. 10. Raise the instrument for comfortable viewing, based on patient height. Move instrument up/down using BOTH knobs. See section on Height Adjustment. 11. Ensure lever is in FAR position. Lever should point to mountain icon.

14

White dot on the knob should match purple dot on label.

Patient Positioning

12. TITMUSi400 only - Turn knob to ensure drum assembly is in FAR position (looking straight ahead). White dot on the knob should match with the purple dot on the label of the knob. See section, Far/Near Vision Testing.

13. Follow the Slide Information Brochure and Record Form provided with specific models for test sequencing and recording.

Patient Positioning Patient must be comfortably seated or standing. Ensure forehead is placed on headrest. Ensure that back is straight and neck is not tilted backwards. Do not let patient continue looking at slide after test is finished. Proceed to next test. Correct patient position.

Incorrect patient position. Back is not straight Neck is tilted. Forehead not placed on headrest.

15

Height Adjustment

Height Adjustment The TITMUSComfort™ height adjustment is designed for patient comfort. The TITMUSi400/i250/i200 can be adjusted to fit children and adults of varying heights in a standing or seated position. This is essential for accurate testing.

To raise/lower the instrument – USE BOTH HANDS on knobs and move upwards/downwards. DO NOT try to use one knob to raise/lower the instrument – this will create a twisting motion and possibly damage the instrument. The instrument height can be adjusted by the operator or the patient.

16

1. Operator is seated on the right or left of the instrument. 2. To move the lever from FAR to NEAR and back, pull the lever to move towards you and push it to move away from you. Ensure that lever is pushed completely to the end. Ensure that lever is pushed completely to the end.

Far Vision Testing

Operating the Far/Near Lever

Far Vision Testing (20ft/6m) 1. Lever in FAR position, indicated by the “Mountain” Icon, test distance of 20 feet. 2. Lens assembly should be in FAR position (looking straight ahead). 3. TITMUSi400 only - White dot on the knob should match with the purple dot on the label of the knob.

17

Near Vision Testing

Near Vision Test (14in/35cm) - Natural Line-of-Sight Lever in NEAR position, indicated by the “Book” Icon, test distance of 14 inches.

TITMUSi400 Only STEP 1: By turning the knob, a progressive lens wearer can be tested at the optimal lineof-sight for testing (looking downwards). STEP 2: Rotate knobs downwards on side of instrument using BOTH hands to adjust for the best line-of-sight. STEP 3: Stop at a point where the images can be seen most clearly by the patient. This applies especially for patients who wear bifocals, multifocals or progressive lenses.

TITMUSi250/i200 Only Natural line-of-sight testing feature is not available. The knobs DO NOT turn. DO NOT try to turn the knobs as this will damage the instrument. Near vision testing for patients who wear bifocals or progressive lenses: Ask patient to use thumbs to raise glasses until he/she is viewing the slide through the proper part of his/her lens for reading. Ask the patient to place hands on the instrument as shown. Ensure that the patient is comfortable.

To Return Back to Far Vision Testing 18

1. TITMUSi400 ONLY – Turn knob so that the white dot on the knob matches with the purple dot on the label of the knob. Use BOTH HANDS to turn the knobs. 2. Move lever from NEAR to FAR.

Ensure lever is in FAR position. Place plus lens in the holder. Perform test. REMOVE lens upon completion of test. Do not turn the knob while the lens is in the instrument.

Using Plus Lens The plus lens must be inserted in the slot with the label facing the front of the instrument. See above images. • The Plus Lens, +1.75, is used with the Acuity test for children. Other plus lenses are also available as optional accessories. • Standard testing procedure requires that acuity test is administered first. If child demonstrates poor visual acuity (20/40), it is unnecessary to administer the Plus Lens Test. If the child demonstrates 20/30 or 20/20, administer the Plus Lens Test. • Children with normal vision will be unable to read the 20/20 line through the Plus Lens. If a child can read the 20/20 line through the Plus Lens, then result is FAIL. Blurred vision through Plus Lens is normal, clear distance vision is abnormal and can indicate excessive farsightedness. This test is very important for school age children.

Peripheral Vision Testing & Instrument Transport

Peripheral Vision Testing Refer to the sections TITMUSi400 Membrane Panel and the TITMUSi250 – Membrane Switches, for location of peripheral vision testing membrane switches.

1. When the instrument is switched ON, the LEFT EYE light will come on first. On the button with arrows, light next to LEFT arrow will be lit. 2. The LEFT EYE can now be tested for Horizontal Peripheral Vision. 3. Press 85, 70, 55 to operate the lights at 850, 700, 550 in the Temporal field. 4. Press N to operate the light at 450 in the Nasal field. 5. Press the button with arrows to test RIGHT EYE for Horizontal Peripheral Vision test. The light next to RIGHT arrow will be lit, light next to LEFT arrow will go off. 6. Repeat the process with the 85, 70, 55 and N for the RIGHT EYE.

Instrument Transport Follow directions in section Unpacking the Instrument in reverse. • Disconnect the power cord. • Disconnect membrane panel and store it at the back of the instrument. • Ensure the bottom lock is engaged. Instrument transport. Instrument transport in case
