Mak-karti Nadglaznicny Reflex

The McCarp supraorbital reflex (D.J. McCarthy, 1874-1958) is a neurological reflex that was discovered by the American neurologist David Joseph McCarthy in 1923. This reflex is a response to stimulation of the supraorbital nerve, which is a branch of the trigeminal nerve.

McCart was one of the first researchers to study reflexes in humans. He was known for his work on the anatomy and physiology of the nervous system. In 1902, McCart published his first work on the supraorbital reflex, in which he described its mechanism and significance in medical practice.

The supraorbital nerve is a branch of the superior trunk of the trigeminal nerve, which innervates the skin of the superciliary arches and frontal region. When this nerve is irritated, a reflex contraction of the muscles of the forehead and brow ridge occurs. McCart discovered that when the supraorbital nerve is irritated, a muscle contraction occurs that lasts for several seconds. This abbreviation can be used to diagnose diseases of the nervous system and brain.

In addition, the supraorbital reflex is of practical importance in medicine. For example, it can be used to assess the state of the nervous system in various diseases such as stroke, traumatic brain injury or depression. This reflex can also be useful in diagnosing cerebrovascular accidents and other diseases of the nervous system.

In general, the Maccarpa supraorbital reflex is an important neurological reflex that has practical applications in medicine and can be used to diagnose and treat various diseases of the nervous system.

The problem of error in diagnosing blindness. (according to researchers of domestic pediatric ophthalmology).

The first reaction of children with bilateral blindness when both eyes are closed is the cessation of speech, hearing, and sometimes muscle movements, which can even turn into a panic attack. This reaction lasts a little less than a second, after which the state of a deaf and blind child normally returns. He could have been scared or, God forbid, had a heart attack, or a drop in blood pressure occurred; these conditions are identical in clinical manifestations, but require different tactics for caring for the child. The occurrence of panic in blind children leads to serious problems in helping them. According to my observations, this can be explained by the short period of effectiveness of the additional irritation for the eye by closing the second of them. About half a second after additional irritation to the first eye, air pressure causes compression of the eyeball without further development of changes in it or in the visual pathways. Thanks to these features, the term “mac-picture supraorbital” reflexes with inhibition of the second pair of cranial nerves arose: closing one eye blocks only the second pair of cranial nerves, while closing the second eye causes apparent undamage to all nerves. Thus, the child temporarily develops visual acuity (therefore, this reflex is also called binocular). Within half a minute, some children develop the same phenomena of blindness as after complete closure of both eyes. But others develop a blind phase,
