Cyclopentolate is the cycloplegic most frequently used in optometric practice and, in all but those situations where complete cycloplegia is required, it is probably the nearest approach to the ideal . Cyclopentolate does not have the toxic potential of atropine, particularly as it is not normally used at home. There have, however, been reports of CNS disturbances . following the instillation of cyclopentolate drops. This temporary disturbance, which recovers in a few hours with no apparent lasting effects, has usually been associated with the use of higher concentrations (2%) than normally employed.
