Cyclopentolate
Encyclopedia
Cyclopentolate is a mydriatic and cycloplegic
agent commonly used during pediatric eye examination
s. Cyclopentolate is also administered as an atropine
substitute to reverse muscarinic and CNS effects of indirect cholinomimetic (anti-AChase) administration.
When used in eye drops in pediatric eye examinations, Cyclopentolate 0.5% and 1.0% is used to stop the eye focusing at near distance, enabling the optometrist, ophthalmologist or orthoptist to obtain a more accurate reading of the focusing power of the eyes.
The drops take around 30 minutes to work and around 24 hours to wear off (with patients advised not to drive a vehicle or operate machinery for the first 12 hours). The pupils become wider when Cyclopentolate is administered, making the eyes more sensitive to light. Close objects (and possibly distant objects) will also appear blurred.
Side effects to Cyclopentolate are rare, but can include effects such as disorientation, incoherent speech or visual disturbances during the 24-hour period that the drug has an effect.
