Much of the pain associated with corneal ulceration is due to the secondary uveitis and miosis, and effective relief can often be gained with topical atropine ( 1 % ), leading to mydriasis.
32.
Tadpole pupil, also known as episodic segmental iris mydriasis, is an ocular condition where the muscles of the iris begin to spasm causing the elongation, or lengthening, of parts of the iris.
33.
Norcaperatic acid increases tone of guinea pig smooth muscle of the small bowel ( ileum ), and that when given to rats, leads to mydriasis, skeletal muscle weakness, and central nervous system depression.
34.
In the eye, atropine induces mydriasis by blocking contraction of the circular pupillary sphincter muscle, which is normally stimulated by acetylcholine release, thereby allowing the radial pupillary dilator muscle to contract and dilate the pupil.
35.
Use of these drugs can be limited, however, by side-effects, including dry mouth, urinary retention, constipation, and visual disturbances such as mydriasis ( dilation of the pupils ) and cycloplegia.
36.
Like amphetamine, 4-hydroxyamphetamine is an agonist of human TAAR1.4-Hydroxyamphetamine acts as an indirect sympathomimetic and causes the release of norepinephrine from nerve synapses which leads to mydriasis ( pupil dilation ).
37.
In an emergency, intravenous clenbuterol or atropine may be used, but care must be exercised with atropine, as it may predispose to adverse systemic side effects such as mydriasis, excitement, GI stasis and colic.
38.
Damage to the oculomotor nerve ( III ) can cause double vision ( diplopia ) and inability to coordinate the movements of both eyes ( strabismus ), also eyelid drooping ( ptosis ) and pupil dilation ( mydriasis ).
39.
Night terrors are also associated with intense autonomic discharge of tachypnea, flushing, diaphoresis, and mydriasis that is, unconscious or involuntary rapid breathing, reddening of the skin, profuse sweating, and dilation of the pupils.
40.
It's also likely to be very dangerous if you have just be given something to dilate the pupil ( causing mydriasis ), e . g . as talk ) 13 : 29, 22 July 2008 ( UTC)
