Role of Cycloplegic Refraction in Evaluation of Refractive Power in Children between 6-14 Years
Shravya.G
Abstract: BACKGROUND AND OBJECTIVES A refractive error is a major cause of treatable visual impairment. Various refractive techniques with accommodation control have been proposed. Cycloplegic retinoscopy is the gold standard for objective refraction compared to Autorefractors. METHODS The study was conducted on 200 eyes from 52 patients with diminution of vision, headache, or asthenopia. Noncycloplegic autorefractometry was done followed by cycloplegic retinoscopy using Heine Streak Retinoscope. The results were analysed using Paired Student t-Test and Bland-Altman plots. RESULTS Bland-altman plots are used to compare spherical, cylindrical, and axial components P value of less than 0.005 is considered to be statistically significant In my study P values are Sphere- 0.000 Cylinder- 0.000 Axis- 0.000 It proves that there is a statisticcaly significant difference between autorefractometer and cycloplegic retinocope in assesseing the refractive errors INTERPRETATION AND CONCLUSION The results confirm that retinoscopy is more accurate than autorefractometry
