Upper age Limits for Cycloplegic Refraction at Mayo Hospital Lahore.
Ophthalmol Update Jan ;15(4):360-2.

Background: Cycloplegic refraction is one of the most reliable procedure to quantify refractive error. Though new methods of refraction have been developed with the advancement of time, but even then cycloplegic refraction is considered a time tested and valid procedure. Objective: The aim of this study was to find out the greatest extend of age for cycloplegic refraction using cycloplegic drops . Methods: One fifty patients (300 eyes) were examined by instilling drops of cyclplegic agent, retinoscopy and auto refraction was performed before instillation of drops and after instillation up to 90 minutes with a regular time interval of 15 minutes after instillation of first drop. The prescription of both eyes and the age of patient are computed Results: All myopic, hyperopic , and astigmatic patients of 7- 10 years of age need cycloplegic refraction. The hyperopic patients of 11-14 years of age need cycloplegic refraction while half myopic and astigmatic patients of 11-14 years of age need cycloplegic refraction and half myopic and astigmatic patients need not cycloplegic refraction. Conclusion: The upper age limits for cycloplegic refraction is 11-14 years of age for hyperopes and 7-10 years of age for myopic and astigmatic patients.
