Screening Lane Setup

The only requirements needed for vision testing with the LED Insta-Line Quantum™ is a 10 foot testing lane, two chairs, a table and an electrical outlet if battery is not used. Place the instrument on a low table, remove front and back panels, insert test chart to be used. Remove the Remote Control Device (RCD) from back holder and unwind power cord.A 10 foot cord is included to measure test distance. One end of the cord should be placed flush with the face of the chart and the other end is pulled tight should be located at the face of the child being tested. After completing testing lane setup plug power cord into a source of 120 VAC, 60 Hz outlet if not using battery. The RCD should be placed on a table with a chair placed on each side of the table. The child faces the instrument while the examiner faces the child with their back to the chart (FIG. 1). This allows the examiner to observe the child at all times, to detect squinting or faulty head positions. No intense light sources should be within the field of vision as the child looks at the instrument from 10 feet away.
RCD overlays (FIG. 2) are provided with each chart. RCD overlays are also available separately (refer to section 21 for more information). Attach RCD overlay with hook and loop fasteners noting bottom label on the RCD and back of overlay.
Remote Control Device (RCD)
Even though each remote control device (RCD) is programmed to communicate with it’s corresponding compatible Insta-Line, it is not recommended to use 2 or more units in the same room. RF signals used to operate the Insta-Line from it’s corresponding remote may interfere with the operations of the other unit.

The RCD has several features built into the electronic design to enhance the overall operation.
Depressing the keypad buttons will turn ON the respective light in the test cabinet. Although each frosted light bulb will turn OFF in approximately thirty seconds, the OFF button may be depressed to turn OFF earlier.The RED muscle light bulbs will stay on for approximately one minute or may be turned OFF earlier by depressing the OFF button.
The RCD resumes a low power mode after the pressed keypad button is released, to conserve battery life. However, the batteries will eventually become too low for proper operation. A built-in battery detector will cause multiple beeps when the keypad is depressed to alert the operator to replace the four (4) AA alkaline batteries. Replace batteries as soon as multiple beeps are heard. Rechargeable batteries should never be used. When the RCD will not be used for several weeks, the batteries should be removed to prevent unnecessary drain.

RCD Battery Replacement

Batteries are removed by sliding off the battery cover. Remove the batteries and replace the new ones with the proper polarity “+” and “-” as indicated inside the battery compartment. When the last battery is inserted into place, a single beep will be produced indicating the RCD is ready to operate.
Replace battery cover.
NOTE: If any batteries are installed incorrectly, multiple beeping will occur when any of the keys are depressed.
Key Press Beep
The RCD emits a beep when a key is depressed. This feature can be turned off by depressing the two outer buttons on the second row from the top.
Depressing the same buttons will turn the beep on again.

Light Test Auto Run
The RCD also includes a light test auto run feature for a quick light test and demonstration purposes. The mode is entered by simultaneously depressing the two lower outside keypad buttons. The lights on the LED Insta-Line Quantum will sequence continually until the OFF key is depressed.

LED Insta-Line Quantum™

The LED Insta-Line Quantum™ is controlled by the RCD explained in Section 3.
Please note that the LED Insta-Line Quantum™ is always on when unit is plugged in or running on battery power.
When the unit is plugged into a source of 120 VAC, 60 Hz power, a short beep will be heard to signal it is ready to operate and receive signals from the RCD. If the beep is not heard, check the AC plug connection for power availability.
When plugged into power, the LED Insta-Line Quantum™ will emit a short beep approximately every fifteen minutes (if a RCD command is not received) to alert the user power is still being applied.
When the LED Insta-Line Quantum™ receives a command from the RCD, the selected light will turn ON and unless commanded to turn OFF by the remote control, will stay ON for only 30 seconds for the frosted light bulbs or 60 seconds for the red muscle light bulbs. However, when the remote control sends the unique two key light test – auto run command, the auto run will continue to run until the OFF key is depressed on the remote control.
WARNING: If service is necessary, return the entire unit with the RCD to the factory for authorized repair. See page 25 for more information.
Optional accessories can be purchased for your LED Insta-Line Quantum™ refer to page 21 for more information.

Amblyopia
In order for a person to see the brain and the eye work together to produce vision. Light enters the eye and is changed into nerve signals that travel along the optic nerve to the brain.
When an infant is born these visual pathways are not mature and visual acuity is poor in both eyes. It improves when the visual pathways carrying signals to the brain and the brain’s cortical functions develop.
If for some reason one eye sees well and the other eye poorly, a double image is sent to the brain. The brain solves the confusion by ignoring the poorer image. This decreases the influence of the poorly seeing eye.
Vision of the poorly seeing eye in the primary visual cortex remains weak, while that of the dominant eye steadily increases. This condition is called amblyopia or lazy eye.
There are several causes of amblyopia: strabismus (crossed eye), unequal refractive error (anisometropia), and other factors causing a difference in image quality between the eyes.
In many cases of amblyopia the eye looks normal, but its visual acuity is at least two lines lower than that of the other eye. If not treated early enough an amblyopic eye may never develop good vision and may even become functionally blind. Therefore in screening we need to find out the best visual acuity of both eyes.
Because amblyopia may develop at any time before 7 years of age it is important to follow the early development of vision. If it shows signs of deviation from the normal development, treatment needs to be started without delay. No “wait-and-see”!
Amblyopia is the most common cause of vision loss in children. A child with one amblyopic eye functions normally but does not have a reserve eye if later in life something happens to the leading eye. Since amblyopia is symptom free it must be found by screening. If there is a difference in visual acuity greater than two lines both at distance and at near, it is highly likely that the eye with lower visual acuity is amblyopic and needs to be treated.
However, the eye may have refractive error and not amblyopia so it is wise not to tell the parents that the eye is a lazy eye. Tell the parents what you have found: “one eye sees less clearly than the other and the cause for that needs to be discovered because the child may need treatment”.

Screening Procedure

From birth to six years of age the vision process matures. If this developmental process is interrupted before six years of age, permanent changes may occur in the visual pathways resulting in amblyopia (lazy eye). Prevention of amblyopia through early identification of children with risk to develop amblyopia, with observable symptoms or visual acuity problems is of primary importance in vision screening. When screening preschool children it is important to find out whether the infant/ child uses both eyes together and how each eye is seeing independently. When testing adults it is customary to test distance vision first, followed by near vision. It is also customary to first test each eye separately, then binocularly. When testing children, better results are obtained by starting with near vision testing before proceeding to distance vision testing. This allows the child to learn the testing procedures and symbols. The examiner learns what to expect from the child under the most favorable conditions. Also, when testing children, it is important to create a pleasant play situation before testing near and distance vision. Test both eyes first, then each eye separately.
During visual acuity testing, near vision is measured first. The functionally important value is the value measured with both eyes open, because that is the vision the child uses in communication and learning.

Details about Testing

Start testing with binocular testing at near. Distance testing and monocular testing with occlusion of one eye follows naturally once confidence with the child is established. When testing monocularly, test the right eye (O.D.) first followed by the left eye (O.S.), unless there is an obvious negative response to occlusion of the left eye. During measurement of distance vision the child should be seated in a chair facing the test cabinet (see FIG. 1). Visual acuity is first measured with both eyes open. Then the left eye is occluded and the right eye is tested. Tell the child you are going to cover one eye. Place your Good-Lite® occluder over the left eye. Remember this is a monocular test, cover the eye well and watch for peekers! Illuminate the optotypes allowing response time between them. Test until the threshold line is reached. The threshold line is the smallest line size that the child can read correctly. Repeat test procedure occluding right eye.
If the child becomes upset when the left eye is covered, quickly move the cover on the right eye and test the left eye first. The right eye may be amblyopic or near sighted.

Definition of Visual Acuity Threshold
According to the Visual Acuity Measurement Standard, “A line of optotypes is generally considered to have been read correctly when more than 50% (e.g. 3 of 5, 4 of 6) of the optotypes presented have been read correctly.”

Suggested Passing
There shall not be a difference between the two eyes greater than two lines in any age group.
3 year olds use 20/40 optotypes
4 year olds use 20/30 optotypes
5 year olds use 20/25 optotypes
7 year olds use 20/20 optotypes
(Above are suggestions, please check your mandated criteria.)

Visual Acuity Matching Objects (optotypes)
LEA SYMBOLS® & HOTV Matching is a good method in determining visual acuity at an early age. The first step is to familiarize the child with the four optotypes before vision screening. Before you begin screening, you can use the optional flash cards for conditioning and ask the child to point to the same shape on the response panel. A verbal response is acceptable if the child is consistently accurate and knows his/her optotypes during the conditioning phase. Continue revealing the flash cards until you are confident the child can point to each shape or can verbally identify each optotype. When the child can respond without difficulty, it is time to start testing with the LED Insta-Line Quantum™ test chart.

The child should be seated in a chair facing the instrument, with the response panel on the table in front of the child (see FIG. 3) if the child prefers matching. The response panel, when placed on the table, should show all the optotypes in their normal upright position (FIG. 3). To start, show a few large optotypes on the test chart. Next, show one optotype on each line in sizes 20/50, then 20/40, 20/30, 20/25 and 20/20 until the child hesitates or misidentifies the optotype. Go up one line and ask the child to read all the lighted optotypes. Repeating previously shown optotypes may be necessary to achieve three out of five correct responses. Always test until threshold (the smallest optotype size the child can correctly read) to be able to detect the difference between the visual acuity values of the two eyes.
Once the child has successfully responded in the binocular testing, the left eye is occluded and the right eye is tested. Tell the child you are going to cover one eye. Place your Good-Lite ® occluder over the left eye. Remember this is a monocular test, cover the eye well and watch for peekers! Illuminate the optotypes allowing response time between them. Test until threshold. Repeat test procedure occluding right eye.

Pass/Fail Criteria – Preschool (distance).
The child must correctly identify 3 out of 5 optotypes at the age appropriate level described in your mandated criteria, If there is a difference between the two eyes greater than two lines, measure monocular visual acuity values at near. If there is the same two line difference in the near visual acuity values, amblyopia should be suspected and the child referred (AAP recommendation 1996).

Muscle Imbalance

The following are required for the test:

1. The red rectangle target that is illuminated by pressing the red muscle button on the RCD.
2. An eight diopter prism with handle.
3. 5×9 inch plastic recognition panel with red rectangles on one side, and black rectangles showing those that pass and fail with explanation on the other side.

Procedure
The subject is to keep BOTH EYES OPEN and look at the red target while the examiner holds the prism VERTICALLY over first one eye and then the other; allow at least 15 seconds for the subject’s response. Older children are asked, “Do the red rectangles (squares) touch or overlap?” When the prism is placed over each eye. If they do, they pass. (See FIG. 4) Another method is to use the 5×9 inch recognition panel.
Children may readily point to the one or pair of rectangles that are like what they saw.

Referrals are made for those who see only one rectangle (SUPPRESSION) and those who see two rectangles that DO NOT overlap.School consultants, states and others differ on the need and method of testing eye alignment (muscles). It is relatively safe to say that this test was not done 25 years ago and that today many schools are referring children for this finding. This test is built into the LED Insta- Line Quantum™ so it is readily available. It refers those with over 6 diopters eso or exophoria, 1 1/2 diopters hyperphoria and suppression. It has a very definite pass or fail response and agrees with the eye doctor’s findings.
This guide for the muscle test are included with the accessories for the test.

Hyperopia
The visual acuity test does not detect hyperopia. Therefore, various plus strength sphere glasses are used to screen out different percentages of hyperopic children.
Glasses are used with this test and they vary in strength from 2.50 diopters for the youngest child to plus 1.75 diopters for adults. These glasses should be worn at least one minute prior to the test to allow for relaxation of accommodation.
Hyperopia is tested with BOTH EYES OPEN and is done with the 20/30 line on the test chart. If the child can read the 20/30 line on the chart he/she fails; if he/she can not, he/she passes.
Both eyes can be tested together, because the examiner is not required to determine if both or just one eye has excessive hyperopia. Individual eye testing would result in a higher number of failures. Also, since the longer the subject looks through the glasses the better he will see, he should wear the glasses one minute before final appraisal.
Those who can read the 20/30 line with both eyes open “fail”. The number who fail is normally about 10 percent, and of this number, only those who are doing less than average work scholastically or who have an obvious positive response to the glasses should be referred.
Hyperopia is a normal condition for children and is harmful to the child only if it affects his muscle balance or reading ability.
Hyperopia testing is of little value in the lower primary grades, because most children have as much as 10 diopters of accommodation, and because books are printed in very large type.
+1.75, +2.25, and +2.50 diopter strength test glasses are available from Good- Lite®.

Suggested Guide for Screening Programs with the use of Good-Lite® Equipment

During the past 30 years school testing of visual acuity has become almost universal. This has been due to the combined efforts of the school nurse, ophthalmologist, optometrist, public health officer, Prevent Blindness America, Lions’ Club and others. Today the question is not whether to give the test, but rather how extensively, how frequently, and how accurately. Accuracy is important because erroneous referrals, over-referrals, will frequently discredit an otherwise splendid program.

All new students are to be given all three tests according to their grade.
Adults over 40 years require a reading test.
Use age appropriate test charts. (LEA SYMBOLS®, Letter, HOTV, etc.)
College students, office and exacting shop workers require 20/20 vision at near and at distance (the normal mean value is 20/16), an excessive hyperopia test and a muscle test.
The above high standards are designed to detect the students who may benefit from a professional examination, especially if their grades are below average. In addition, it must be kept in mind that any screening test for such complicated mechanisms as VISION, must be considered only a partial testing. Passing the tests does not mean that the eyes and vision are normal. SCREENING IS APPLICABLE TO SYMPTOM FREE INDIVIDUALS ONLY. Therefore, other factors such as poor grades, inflamed eyes, and faulty head and eyelid positions should be used as additional criteria for referrals.

Some of the reasons for doing these tests as outlined are:

1. Early detection of amblyopia is essential to successful treatment. The difference in the vision of each eye is important. For example, a child with 20/40 and 20/25 or 20/30 and 20/20 vision is the other eye is in greater need of referral than a child with 20/40 vision in each eye.
2. Children are almost never aware of their poor vision. Someone must point it out to them. The Biannual visual acuity test is ADVISABLE because myopia MAY RAPIDLY increase in the growing child. Generally a child is greatly handicapped for blackboard work when his vision is less than 20/30.
3. The reason for the hyperopia test is to save the far sighted child excessive eye strain. Eye glasses worn at least for study may be of great value.

Preschool and Kindergarten Acuity Testing
Kindergarten and preschool children can be easily tested with the LEA SYMBOLS® by Lea Hyvärinen, M.D. or HOTV by Otto Lippmann, M.D. These optotypes adhere to recognized standards. They are not reversed when viewed in a mirror, so they can be used with children who have difficulty with mirrored images.
The LEA SYMBOLS® and HOTV matching method will determine visual acuity more accurately and at a younger age than any other method. The first step is to familiarize the child with the four optotypes which are referred to as objects. Use the optional flash cards for this purpose. It is suggested that the LEA TEST or HOTV be used with the LED Insta-Line Quantum™ or with the Good-Lite® No. 600600 Eye Cabinet. When an object is shown on the chart, the child is asked to match it with an object on his response panel. The child may either point to or cover up the object on the response panel to indicate his choice. Vision is recorded at the line where 4 out of 6 responses are correct.
LEA SYMBOLS® and HOTV sets are also available for testing with portable charts.

Color Vision

During the last five years there has been an increased interest in color vision. Children are never color blind, but 5% or more of the boys are color deficient for red and/or green. They generally can state the color of objects but can not match colors in fine shades of orange-yellow-chartreuse, or blue green to purple. They have a congenital defect that is not correctable. The value of the test is to warn students, teachers and parents of this defect. For this test, we recommend Good-Lite® No. 730000 16 Plate Color Test. Its durable non-fading color plates are mounted in a loose-leaf binder and can easily be replaced if soiled.
IT IS A VERY SENSITIVE SCREENING TEST AND DOES NOT REVEAL THE SEVERITY OF THE COLOR DEFICIENCY. SOMETIMES A PERSON WITH NORMAL COLOR VISION MAKES ERRORS IN THIS TEST. THEREFORE POSITIVE FINDINGS SHOULD BE CHECKED WITH A QUANTITATIVE TEST (#260100) FOR QUANTIFYING COLOR DEFICIENCY.

Near Vision (Near Point)
Near vision cards should be used in the lower grades to determine reading readiness. Good-Lite® has several products to help assess near vision.
Between the ages of 40 and 45 people lose their ability to read close or accommodate. Good-Lite® has a suitable reading card for testing reading vision.

Referral Slips
Each school has its own form for yearly health records and referral slips to doctors. The report to the doctors would be of greatest value if it gave the reason for referrals such as:

1. Poor distant vision
2. Reading difficulty
3. Failure of hyperopia test
4. Muscle imbalance
5. Inflamed eyes.

The form should then be returned to the school by the doctor indication:

1. Corrected vision in each eye
2. When glasses are to be worn
3. Special consideration in school, such as front seat, large print, selection of games suited for children without depth perception, etc.

Those Wearing Glasses
Many eye consultants prefer that the children wearing glasses should not be screened, but the advantages of testing children who are wearing glasses are as follows:

1. All children are tested equally
2. Children with glasses generally average poorer vision than those without, and some may require special classes or consideration
3. Errors such as wearing an old prescription or someone else’s glasses can be checked.

HOWEVER, USUAL SCREENING PASS/FAIL LIMITS DO NOT APPLY IN THESE CASES BUT HAVE TO BE COMPARED WITH THE RESULT REPORTED BY THE CONSULTING DOCTOR.

An Ideal Eye Program

This program will require teamwork between the visual acuity examiner, parents, doctors and teachers.

1. Testing at near and at a distance with standard size equipment similar to that used by eye doctors.
2. Cooperation with the local eye doctor adjusting the referrals up or down to avoid under- and over-referrals.
3. Parents and teachers must understand each child’s situation and follow the doctor’s recommendation as to when and how much the glasses or other aids are to be worn.
4. Special education will be required for a few severely visually impaired children.

Visual acuity, faulty eye alignment, and other conditions are readily detectable in preschool and school children. Their detection and correction, or help from special education can be the most rewarding function of our schools.
However, it is important to remember that there are children whose visual acuity and eye alignment are normal, yet they have major problems with the use of vision because of brain damage related vision impairments.
Reimbursement
The standard code for acuity vision screening is 99173 “screening test of visual acuity, quantitative, bilateral”.
