2. Fixation disparity - Wikipedia

   en.wikipedia.org/wiki/Fixation_disparity

   the slope of the curve near zero prism load; Fig. 3: Fixation disparity as a function of the forced vergence angle which is induced by base-in prisms and base-out prisms in front of the eyes. These prism FD-curves have widely been used for subjective fixation disparity [13] [11] and the clinical

3. Exotropia - Wikipedia

   en.wikipedia.org/wiki/Exotropia

   Specialty. Ophthalmology. Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...

4. Exophoria - Wikipedia

   en.wikipedia.org/wiki/Exophoria

   Exophoria. Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward. [1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another. [2] The axis deviation in exophoria is usually mild compared with that of exotropia.

5. Cover test - Wikipedia

   en.wikipedia.org/wiki/Cover_test

   A cover test or cover-uncover test is an objective determination of the presence and amount of ocular deviation. It is typically performed by orthoptists, ophthalmologists and optometrists during eye examinations. The two primary types of cover tests are: the alternating cover test. the unilateral cover test (or the cover-uncover test).

7. Vergence - Wikipedia

   en.wikipedia.org/wiki/Vergence

   The two eyes converge to point to the same object. A vergence is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision. [1] When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina ...

9. Maddox rod - Wikipedia

   en.wikipedia.org/wiki/Maddox_rod

   The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. [1] Dissociation of the deviation is brought about by presenting a red line image to one eye and a white light to the other, while prisms are ...
