cyclopentolate

This is a moderate strength dilating drop used in the office to enlarge the pupils. This dilating drop lasts longer than tropicamide and is usually reserved for dilating children as they have strong eye muscles and are harder to dilate.  This drop also has cycloplegia effects and is helpful when performing cycloplegic refraction in children.  I occasionally prescribe cyclopentolate to help with photophobia (eye pain) for people with internal eye inflammation, such as from iritis or uveitis.
