Oculocardiac reflex can be profound during eye examination for retinopathy of prematurity. [5] However, this reflex may also occur with adults. Bradycardia, junctional rhythm and asystole, all of which may be life-threatening, [6] can be induced through this reflex. This reflex has been seen to occur during many pan facial trauma surgeries due ...
In medicine, the caloric reflex test (sometimes termed ' vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel Prize in 1914 for this discovery.
Reflexes include pupillary response (fixed pupils), oculocephalic reflex, corneal reflex, no response to the caloric reflex test, and no spontaneous respirations. Brain death can sometimes be difficult to differentiate from other medical states such as barbiturate overdose , acute alcohol poisoning , sedative overdose, hypothermia ...
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. Moro reflex, a primitive reflex— only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected loud ...
A reflex hammer is used for this testing. "2+ symmetric, downgoing plantar reflex" Sensation: Sensory system testing involves provoking sensations of fine touch, pain and temperature. Fine touch can be evaluated with a monofilament test, touching various dermatomes with a nylon monofilament to detect any subjective absence of touch perception ...
The vestibulo-ocular reflex (VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement. Gaze is held steadily on a location by producing eye ...
If patient is unable to follow any commands, assess the horizontal eye movement via the oculocephalic maneuver. This is done by manually turning the patient's head from midline to one side and assessing the eye's reflex to return to a midline position. If the patient has isolated peripheral nerve paresis assign a score of 1
The Krimsky test is essentially the Hirschberg test, but with prisms employed to quantitate deviation of ocular misalignment by determining how much prism is required to centre the reflex. [2] The Krimsky test is advisably used for patients with tropias, but not with phorias.
