Theuse of cycloplegics is useful in refraction and there are ceain situations where they are indicated. Because of their strong accommodative reserve, very young people (< 16 years) should always be refracted after the use of cyclopleagics : - < 5 years of age : - Atropine 1% ointment is the drug of choice. 15 - 20 years : - Homatropine (2% drop), cyclopentolate (1% drop) or tropicamide (5%, 10% drop) are used.
