Worth 4 dot test
Synonyms	W4LT
Purpose	assess degree of binocular vision

The Worth Four Light Test, also known as the Worth's Four Dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image. The Worth Four Light Test is also used in detection of suppression of either the right or left eye. Suppression occurs during binocular vision when the brain does not process the information received from either of the eyes. This is a common adaptation to strabismus, amblyopia and aniseikonia.

The W4LT can be performed by the examiner at two distances, at near (at 33 cm from the patient) and at far (at 6m from the patient). At both testing distances the patient is required to wear red-green goggles (with one red lens over one eye, usually the right, and one green lens over the left) When performing the test at far (distance) the W4LT instrument is composed of a silver box (mounted on the wall in front of the patient), which has 4 lights inside it. The 4 lights are arranged in a diamond formation, with a red light at the top, two green lights at either side (left and right) and a white light at the bottom. When performing the test at near (at 33 cm ) the 4 lights are arranged in exactly the same manner (diamond formation), with the difference being that at near, the 4 lights are located in a hand held instrument which is similar to a light torch.

Because the red filter blocks the green light and the green filter blocks the red light, it is possible to determine if the patient is using both eyes simultaneously and in a coordinated manner. With both eyes open, a patient with normal binocular vision will appreciate four lights. If the patient either closes or suppresses an eye they will see either two or three lights. If the patient does not fuse the images of the two eyes, they will see five lights (diplopia).

Indications for use[edit]

The Worth Four Light Test is indicated for use when assessing the binocular functions, the ability of eyes to work in coordination, of an individual. It can be used to develop a diagnosis or to support or confirm an initial diagnosis. It can be used when wanting to assess whether the individual has a normal or abnormal binocular single vision response (BSV). It can be used to establish whether a patient has the ability for the eyes to fuse the light that is received from each eye into 4 lights. The test is indicated with the use of a presence of a prism in individuals with a strabismus and fusion is considered present if 4 lights are maintained, with or without the use of a prism. The W4LT can also be indicated when aiding a person to develop and strengthen their fusional capacities.

If the images are unable to be fused the W4LT is still indicated to help to determine if an individual appreciates diplopia (double vision) or are suppressing an image from one eye. In cases of manifest strabismus the test can help in determining the nature and type of the diplopia or which eye is suppressing. Therefore, is indicated in cases of a suspected central suppression scotoma as it can be used to detect where the lights may not be appreciated from the eye with the scotoma though in some cases of minimal deviation in the eye as demonstrated in a microtropic deviation a normal response of 4 lights may be reported. Though it can be used in these patients to prove the presence of peripheral fusion and that they have bi-foveal fixation.

Other indications for the test include establishing an individual's dominant eye dominant eye compared to the other and when evaluating reduced monocular visual acuity which shows no improve on pinhole testing.

Whilst there are no contraindications of the W4LT there needs to be caution in interpreting the results of individuals with BSV in natural conditions as they may show a diplopic response under the dissociation of the test. Also in individuals who have abnormal retinal correspondence (ARC) they may provide an unexpected response, and those who have misaligned visual axis whom in natural conditions suppress may actually provide a diplopic response upon testing.

Method of assessment[edit]

The Worth Four Light Test is relatively simple to undertake. First you must place the red/green goggles over the patients eyes, with the red goggle traditionally placed over the right eye.

Next you must dim the room lighting. This allows the patient to see the lights better.

For a distance measurement, you should have the patient set up six metres away from the light source. For a near measurement, the test should be performed at approximately one third of a metre, or thirty three centimetres, with a handheld Worth’s Four Lights torch.

Then, ask the patient what they see. They should respond with “I see … number of lights” provided they have understood what you have asked them.Ask them to describe the lights to you. You must ask about the colour of the lights. If they see five lights, ask whether the green dots are higher or lower than the red dots. Ask about the positioning of the dots, for example are the red dots to the left or the right of the green dots. Also ask if the dots are flashing on and off or switching between red and green.

This series of questions is essential in order to ensure you correctly record exactly what the patient is seeing, so that the clinician can interpret the patient’s results and then make an accurate diagnosis.

Recording and interpreting outcomes[edit]

When recording results for the W4LT it is important to ask the patient a series of questions in order to ensure you correctly record exactly what they are seeing. This is essential in order to interpret the patient’s results and then make an accurate diagnosis.

The questions are:

How many lights are you seeing?
What colour are they? Where are they located?
Are all the lights in line? Or are some higher than the others?
Do all the lights show up at one time, or are they flashing on and off?

When recording results it is important to indicate the test used, a description of the lights seen and an indication of what the result means. It is also important to note the distance at which the test was conducted and whether or not the patient wore their own refractive correction.

Where communication is difficult between clinician and patient, such as in the presence of a language barrier, or when working with a child, it may be a good idea to get the patient to draw what they are seeing. The clinician can then interpret the results fr
