Does cycloplegia lead to reduced vision during a pseudomyopia test?
AUG 19, 2021
When a child has eye drops to test for pseudomyopia, the pupil dilates, so this lead to reduced vision (even if ciliary muscle is relaxed)?
The mechanism of cycloplegia (relaxing the ciliary muscle, which helps the eye change focus) and dilating the pupil both aid detection of the true refractive error. Pseudomyopia occurs when a patient focuses their lens during the refraction making them appear to have myopia (nearsightedness). With the drops a patient with no refractive error cannot see at near, but can at distance; the nearsighted patient can still see up close but not at distance unless a corrective lens is provided.
