What are dilated eye drops?
dilating eyes are a type of drugs served in the eyes to expand or spread. Mydriatic eye drops are also called. They consist of a solution of water chloride and sodium chloride (NACL), commonly called physiological solution containing drugs that cause pupils' dilation, called mydriatic drugs. Eye dilation drops are used for eye examination, eye surgery and treatment of some visual impairment. Pupils dilate Naturally in Low-Light Conditions So That The Eye Receivors More Light To See and Contract in Brighter Conditions to Prevent Too Much Light From Getting in. SOME Chemicals Can Cause the Pupils to Remain dilated even when the amount of light reaching the Eyes Would Normally Cause Them to Contract, and Condition Called Mydriasis.
The mydriatic Drugs WHICH MEANS THAT THEY BLOCK The Neurotransmitter called acetylcholin.To disrupts the normal transmission of signals from the parasympathetic nervous systemRiens are controlled by various body processes that occur unconsciously. One of its duties is to signal pupils to expand or withdraw according to the amount of light detected, so that the use of anticholinergic drugs to the eyes temporarily prevents pupils from receiving the instructions of the parasympathetic nervous system for the contract.
commonly used short -acting anticholinergic agents used in dilating eye drops include homatropin (C 16 h 21 3 ) and tricamide these medicines usually cause mydriasi for only a few hours. surgery performed in the eyes. Other anticholinergic drugs used in the eyes of painting dicaps have longer effects. For example, medicinal atropine (C 17 h 23 3 ) can cause mydriasi for one or more. Longer lEeks are used in dilating eye drops for long -term use, such as the treatment of some types of glaucoma and improvement of people's vision with eye problems, such as cataracts or dislocated lens, a condition called ectopia lentis.
mydriasis can also be induced by sympathomimetic drugs that have effects similar to the effects of neurotransmitters associated with a sympathetic nervous system such as epinephrine and norepinephrine. The sympathetic nervous system controls the body's response to stress, which includes pupils' dilation during response to combat or flight. Thus, the use of sympathomimetic eye drugs can cause them to react as if they were given instructions from the sympathetic nervous system. An example of these commonly used in the expansion drops is the short -term mydriatic agent (C 9 H 13 No 2 ), which can connect with adrenergic receptors in cells and imitate the effects of epinephrine.
