Regarding Isochoric Pupils And The Mechanism Of Fainting?
, want to ask. why isochoric pupils? And how did it happen or the mechanism fainted?
Hello Armellia, thanks for the question to HealthReplies.com
Pupils are the part of the eye that can widen and shrink which has the function to regulate the amount of light entering the eye. This dilation and reduction in pupil size is regulated by the muscles in the iris (the part that gives the eye color). Pupils will widen if the surrounding light is dim so that more light can enter the eye and the eye can see better in dim light, and will shrink when the ambient light is very bright so that the eye does not glare. Isokor pupil means that pupils in both eyes are the same size. This condition is a normal condition. The condition in which the pupils in both eyes are not the same size is called the anisochoric pupils, conditions that can occur due to disorders in the brain (brain bleeding, brain tumors, increased pressure in the brain), disturbances in the eye (increased pressure in one of the eyeballs, eye tumors), other neurological disorders (for example there are eye muscle palsy), post eye surgery, etc.
Fainting is a sudden decrease in consciousness and occurs only briefly. Fainting can occur due to a decrease in blood flow to the brain which causes a temporary decrease in oxygen in the brain. The causes of decreased blood flow to the brain can vary, for example:
Vasovagal syncope, such as fainting that occurs when seeing blood or blood drawn, see wounds on the body, standing for a long time, the air is too hot, high emotions suddenly, straining too strong, etc.
Heart disorders (heart rhythm disorders, heart attacks, heart valve disorders)
Disorders of the nervous system (epilepsy, parkinsonism, TIA)
Other causes (psychiatric disorders, metabolic disorders (eg hypoglycemia))
So much information from me, hopefully enough answer
