Cover Uncover Test Cranial Nerve
Cover Uncover Test Cranial Nerve. Following the cover and uncover tests, the apct is carried out to measure the angle of the manifest plus latent strabismus. Stand or sit facing the patient in a darkened treatment area.
Turn on the flashlight and then turn it towards the patient's eye for about 1 to 2 seconds using a quick lateral to medial movement. The joint should be supported and pt. It is typically performed by orthoptists, ophthalmologists and optometrists during eye examinations.

The following is a summary of the cranial nerves and their respective functioning. A physician should approach the examination in a systematic fashion and go through the cranial nerves in their numerical order. The test is done by using an opaque or translucent occluder to cover one eye.
The Tests Should Be Repeated Three Times To Check.
Motor examination • muscles are usually innervated by one nerve and by more than one nerve root • observe position of the joints and note any signs of wasting and fasciculation in the muscles. When testing the cranial nerves one must be cognizant of asymmetry. Most examiners do the cover test and uncover test sequentially;
If No Tropia Is Present And The Uncovered Eye Shows Refixation During The Alternate Cover Test, The Patient Has A Latent Deviation (A Phoria).
Turn on the flashlight and then turn it towards the patient's eye for about 1 to 2 seconds using a quick lateral to medial movement. This test is done for both distance and near. To test the vagus nerve, ask the patient to say “ah,” which will cause the pharynx to elevate, and observe the position of the uvula.
Repeat The Above Procedure Twice For Each Eye To Observe The Direct Response In The Ipsilateral Eye (Cn Ii).
•cranial nerve abnormalities are unlikely to occur in mild tbi •since mild tbi needs a normal head ct scan, thus cranial nerve abnormalities in the setting of mild head trauma merit further investigation for another cause. It may be comitant or incomitant, or it may even alternate with gaze direction. Moves the joint against the doctor’s resistance.
7,14,18 Some Skew Deviations Are Known To Mimic Trochlear.
A cover is held in front of one eye and left there for several seconds while the patient fixates an object (e.g., reads letters on a chart). Stand or sit facing the patient in a darkened treatment area. Hypertropia od primary gaze hypertropia most marked with right head tilt hypertropia diminished, almost absent, left head tilt hypertropia almost fully corrected with prism glasses at distance.
