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.
Test can be performed at any fixation distance - near or far; Results of the test can be checked/confirmed using Bagolini glasses, W4LT (macular torch) or Synoptophore; Post-strabismus surgery aim at times, can use in post-op review; When measuring the suppression scotoma, it needs to be done on cooperative patients
During an eye examination, the presence of suppression and the size and location of the suppression scotoma may be the Worth 4 dot test (a subjective test that is considered to be the most precise suppression test), or with other subjective tests such as the Bagolini striated lens test, or with objective tests such as the 4 prism base out test.
Cyclotropia can be detected using subjective tests such as the Maddox rod test, the Bagolini striated lens test, [6] the phase difference haploscope of Aulhorn, [6] or the Lancaster red-green test (LRGT). Among these, the LRGT is the most complete. [7] Cyclotropia can also be diagnosed using a combination of subjective and objective tests.
Static retinoscopy is performed when the patient has relaxed accommodative status. This can be obtained by the patient viewing a distance target or by the use of cycloplegic drugs (where, for example, a child's lack of reliable fixation of the target can lead to fluctuations in accommodation and thus the results obtained). Dynamic retinoscopy ...
