Tropicamide, sold under the brand name Mydriacyl among others, is a medication used to dilate the pupil and help with examination of the eye. [3] Specifically it is used to help examine the back of the eye. [4] It is applied as eye drops. [3] Effects occur within 40 minutes and last for up to a day. [3]
Mydriasis is the dilation of the pupil, usually having a non-physiological cause, [3] or sometimes a physiological pupillary response. [4] Non-physiological causes of mydriasis include disease , trauma , or the use of certain types of drugs .
It is commonly used as an eye drop during pediatric eye examinations to dilate the eye and prevent the eye from focusing/accommodating (cycloplegic). Cyclopentolate [citation needed] or atropine can also be administered to reverse muscarinic and central nervous system effects of indirect cholinomimetic (anti-AChase) administration.
Infants and children who have scabies may be tired and irritable from lack of sleep, since scratching at night can keep them awake, and unlike adults, children often get blisters or large nodules ...
Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve.. A constriction response (), [1] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.
Hydroxyamphetamine is used in eye drops to dilate the pupil (a process called mydriasis) so that the back of the eye can be examined. This is a diagnostic test for Horner's syndrome . Patients with Horner's syndrome exhibit anisocoria brought about by lesions on the nerves that connect to the nasociliary branch of the ophthalmic nerve . [ 7 ]
It is used in eye drops as a cycloplegic (to temporarily paralyze accommodation), and as a mydriatic (to dilate the pupil). The related chemical compound homatropine methylbromide (methylhomatropine) is a different medication. Homatropine is less potent than atropine and has a shorter duration of action. It is available as the hydrobromide salt.
Effects of anticholinergic drugs include: Delirium (often with hallucinations and delusions indistinguishable from reality) Ocular symptoms (from eye drops): mydriasis, pupil dilation, and acute angle-closure glaucoma in those with shallow anterior chamber [11] [12] [13] Anhidrosis, dry mouth, dry skin; Fever; Constipation; Tachycardia; Urinary ...
