Mydriatics anticholinergics

The antimuscarinic properties result in what are usually the most troublesome adverse effects dry mouth, blurred vision, constipation, and (mainly in older males) urinary hesitancy and retention. Pupil size, and hence risk of glaucoma, is determined by a balance between anticholinergic (mydriatic) and sympathomimetic (miotic) effects. [Pg.176]

Figure 20-6 Mechanics of pupillary dilation. (A) Components of iris muscle activity. Medial component of iris sphincter activity (M), lateral component of iris dilator activity (L), and posterior component of iris dilator activity (P). (B) Pupillary dilation with anticholinergic mydriatic. The iris sphincter is inactivated, and the posterior component of the iris dilator acts peripherally. (C) Pupillary dilation with adrenergic mydriatic. The iris dilator is stimulated, and its posterior component is augmented while the medial component of the iris sphincter persists.

Anticholinergic mydriatics Anticholinergic mydriatics (see chapter 15) dilate the pupils for diagnostic procedures and ophthalmic surgery. Adverse effects are tachycardia, photophobia, dryness of the mouth, edema, conjunctivitis, and dermatitis. [Pg.345]

The medication used to dilate the pupils for diagnostic procedures and ophthalmic surgery is anticholinergic mydriatics. [Pg.351]

Eye disorders are treated using a topical anesthetic, antiinfectives, antimicrobials, lubricants, miotics, carbonic anhydrase inhibitors, osmotics, anticholinergic mydriatics, and cycloplegics. [Pg.432]

Sympathomimetics are used to produce mydriasis for ophthalmoscopic evaluation mydriasis is not maximal, as with the anticholinergic mydriatics, but especially in younger patients sympathomimetic mydriasis proves quite effective and causes little or no reduction in accommodation. Sympathomimetic agents are also used as vasoconstrictors in surgical procedures, for symptomatic relief or allergic reactions and hyperaemia of the conjunctiva, and to lower intra-ocular pressure in glaucoma. [Pg.361]

Mechanism of Action An anticholinergic agent that exerts an atropine-like action and produces an antispasmodic effect on smooth muscle, is a potent mydriatic, and inhibits salivation. Therapeutic Effect Relieves symptoms of Parkinson s disease and drug-induced extrapyramidal symptoms. [Pg.1035]

Tropicamide is an anticholinergic drug that tends to have a greater mydriatic than cycloplegic effect. It is a short-acting atropine-like derivative and has been regarded as an effective and safe mydriatic, used for pupillary dilatation by professionals, who are not always medical doctors. [Pg.3530]
