Charpentier Phenomenon

Charpentier Phenomenon: An Adjustment Disorder Researched by a French Ophthalmologist

Charpentier's phenomenon, also known as a symptom of adjustment disorder, was first described by the French ophthalmologist Charpentier in 1884. This phenomenon refers to disturbances in the adaptation of the eyes to various lighting conditions and manifests itself in the form of a decrease in visual acuity and/or changes in color perception.

Charpentier Phenomenon is a consequence of dysfunction of the eye's adaptation mechanisms to various lighting conditions, including changes in the brightness and color of light. This can occur as a result of various factors, such as eye diseases, environmental changes, and nervous system disorders.

Symptoms of Charpentier Phenomenon may include various changes in visual perception, such as decreased visual acuity, eye discomfort, changes in color perception, and others. These symptoms usually occur when changing from one lighting to another, also known as "adaptation."

Although Charpentier Phenomenon can be unpleasant for those who experience it, it is usually not a serious condition and can be resolved in most cases. In some cases, you may need to consult a doctor and prescribe treatment, especially if symptoms are caused by eye disease or other factors.

Overall, Charpentier's Phenomenon continues to be researched by the scientific community, and many studies are being conducted to better understand the mechanisms of its occurrence and better treatments for this disorder. However, thanks to Charpentier's original work, we have a clearer understanding of this phenomenon and how to treat it.

**Charpentier - a phenomenon** or a symptom of adjustment disorder?

Charpentier - phenomenon - sensory neuron depletion syndrome (a symptom of general decompensation of body functions).

This condition can occur as a result of traumatic influences or deep fatigue of the nervous system. It may be accompanied by hallucinatory and delusional phenomena, hyperacusis (exacerbated hearing), circulatory disorders, and chills. The basis of the disease is inhibition, absent-mindedness, loss of interest in the outside world, and sleep disturbance. A person experiences psycho-emotional depression and increases irritability. Without treatment, Charpentier syndrome can lead to coma or death. But it is too early to talk about such a sad outcome, because the effect after therapy lasts for each patient individually. Recovery depends on the quality of care provided and on the individual characteristics of the clinical case. Psycho-emotional and physical overloads lead to the emergence of a clinical picture. They place an unbalanced load on the body and lead to neuroticism. Such people need to have mental protection and also be under the supervision of doctors. There are no other ways to help the patient. The symptom is observed in patients of different ages, but most often appears with acute mental trauma or in young people in search of
