Red-green ophthalmic goggles designed for the Worth 4 Dot Test, binocular vision assessment and diplopia evaluation, helping eye-care professionals investigate fusion, suppression and ocular misalignment.
The IndoSurgicals Red/Green Diplopia Goggles are ophthalmic examination goggles designed to provide red-green dissociation of the two eyes during binocular vision testing.
The goggles are particularly useful during the Worth 4 Dot Test, where red and green filters allow selected test lights to be perceived differently by each eye. The patient's response provides useful clinical information about binocular sensory status, including fusion, suppression and diplopia.
They may also be used as part of clinical diplopia and prism fusion assessment to help the examiner understand how the two eyes are working together and evaluate image separation or fusion under dissociated viewing conditions.
Suitable for use with the Worth 4 Dot Test for assessment of binocular sensory function.
Separate coloured filters provide different visual information to the two eyes during examination.
Helps clinicians assess whether visual information from the two eyes is being combined into a single binocular percept.
Useful during evaluation of patients reporting double vision and for investigating binocular misalignment.
May be used alongside prism assessment when evaluating the prism power required to achieve image alignment and fusion.
Supplied in a brown spectacle frame for convenient use during clinical testing.
The Worth 4 Dot Test is a commonly used binocular vision test that helps determine whether the two eyes are functioning together under dissociated viewing conditions. Red/green goggles form an essential part of this examination.
During the test, the coloured filters control which test lights are visible to each eye. The number and colour of lights reported by the patient help the examiner evaluate the patient's binocular sensory response.
A fused response indicates that visual information from both eyes is being used together during the test.
Visibility of information associated predominantly with one filter may indicate suppression of the fellow eye, depending on the test response and protocol.
Perception of separated red and green target groups may indicate diplopia and provides information regarding the relationship between the two visual axes.
The red and green filters selectively transmit corresponding wavelengths of light. When paired with an appropriate red-green test target, the two eyes receive different visual information.
The examiner evaluates how the patient perceives the separate images. This helps assess whether the eyes are fusing normally, whether one eye is being suppressed, or whether separate images are perceived.
Diplopia, or double vision, occurs when a single object is perceived as two images. Red/green dissociation provides a simple method of distinguishing the visual image associated with each eye during examination.
By observing the relationship between the red and green images, an eye-care professional can obtain useful information about ocular alignment and the pattern of binocular separation. This information is interpreted together with other clinical examinations when investigating the cause and characteristics of diplopia.
Red/green goggles may also be employed during prism fusion assessment. The coloured filters help maintain identification of the visual image seen by each eye while prisms are introduced or adjusted by the examiner.
The patient wears the red/green goggles while viewing an appropriate test target, enabling each eye's image to be identified separately.
The clinician determines the relative position of the images perceived through the red and green filters.
Appropriate prisms may be introduced clinically to alter the relative position of the images and investigate the patient's ability to achieve single fused vision.
The prism response is interpreted together with ocular motility, alignment and other binocular vision findings when developing an appropriate clinical management plan.
Red/green dissociation testing is useful in a variety of binocular vision examinations. The IndoSurgicals Red/Green Diplopia Goggles provide a simple and convenient means of introducing colour dissociation without requiring a complicated optical system.
They are suitable for use by ophthalmologists, optometrists, orthoptists and other appropriately trained eye-care professionals in hospitals, eye clinics, vision centres and teaching institutions.
