ABSTRACT
Purpose:
To analyze the refractive shift during off?the?axis retinoscopy under cycloplegic drugs in myopic patients during ocular examination.Methods:
Prospective cross?sectional study was carried out among 10 myopic patients having refractive errors of ?3.00 D or less. All the subjects underwent cycloplegic refraction by a single examiner at 0°, 10°, and 20°. Descriptive data were analyzed as mean and standard deviation. Paired t?test was used to compare the mean differences between on?axis (0°) and off?axis (10° and 20°) retinoscopy.Result:
The mean spherical equivalent refraction of 10 myopic patients showed an increase in myopic shift with approximately 7% and 18% for 10° and 20° of eccentricity, respectively. Similarly, the mean spherical equivalent measure on axis (0°) and off axis (10° and 20°) were ?2.5495, ?2.737, and ?3.0265, respectively. The mean spherical equivalent differences between on?axis (0°) and off?axis (10° and 20°) showed statistically significant differences with P < 0.05.Conclusion:
This study concluded that a greater degree of eccentricity will induce a greater amount of errors in retinoscopy
