The reflex is absent in infants under nine months. The examination of the corneal reflex is a part of some neurological exams, particularly when evaluating coma, such as FOUR score. Damage to the ophthalmic branch (V 1) of the trigeminal nerve results in absent corneal reflex when the affected eye is stimulated. Stimulation of one cornea ...
In the fields of optometry and ophthalmology, the Hirschberg test, also Hirschberg corneal reflex test, is a screening test that can be used to assess whether a person has strabismus (ocular misalignment). A photographic version of the Hirschberg test is used to quantify strabismus. [1]
Corneal reflex is conducted along with the facial nerve section of the test. Note the sensory innervation of the cornea is provided by the trigeminal nerve while the motor innervation for blinking the eye is provided by the facial nerve.-Muscles of mastication (temporalis, masseter) should be inspected for atrophy. Palpate the temporalis and ...
Light from a single point of a distant object and light from a single point of a near object being brought to a focus. The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size.
Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex; Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs.
Since both the short and long ciliary nerves carry the afferent limb of the corneal reflex, one can test the integrity of the nasociliary nerve (and, ultimately, the trigeminal nerve) by examining this reflex in the patient. Normally both eyes should blink when either cornea (not the conjunctiva, which is supplied by the adjacent cutaneous ...

supraorbital pressure - this is the manual stimulation of the supraorbital nerve by pressing a thumb into the indentation above the eye, near the nose. [ 2 ] sternal rub - this involves creating a turning pressure (akin to a grinding motion with a pestle and mortar) on the patient's sternum [ 1 ]
