Cycloplegic Refraction
Refractive measurement performed after pharmacologic paralysis of accommodation to obtain accurate readings in children.
Full Definition
Cycloplegic refraction involves the use of anticholinergic medications to temporarily paralyze the ciliary muscle, preventing accommodation during refractive assessment. This technique is essential in pediatric patients because their strong accommodative ability can mask hyperopia and lead to inaccurate prescriptions. The procedure typically uses agents like cyclopentolate or atropine, with atropine providing longer-lasting cycloplegia but requiring days for recovery. Results from cycloplegic refraction are considered the gold standard for determining true refractive error in children and are crucial for proper spectacle prescription.
Usage
Usage note: Always specify the cycloplegic agent used when documenting results.
