Atropine

Topical instillation of atropine causes mydriasis, abolition of light reflex and cycloplegia lasting 7-10 dys. The cilliary muscles recover somewhat earlier than sphincter pupillae. This results in photophobia and blurring of near vision. The intra ocular tension tends to rise, specially in narrow angle glaucoma; conventional systemic doses produce minor ocular effects.

Indications

Long acting mydriatic & cycloplegic for use in uveitis & during refraction. Iritis, iridocystitis, choroditis, keratitis & corneal ulcer.

Dosage

1-2 drops to be instilled in each eye. Oint for use at night.

Contra-Indications

Narrow iridocorneal angle-may precipitate acute congestive glaucoma.

Side Effects

Dilated pupil, photophobia, blurring of near vision, palpitation.
