Refractive errors are a noteworthy cause of visual disruption worldwide. Objective: To compare the results of dynamic and cycloplegic retinoscopy in children. Methods: A descriptive-type cross-sectional study was conducted at the university of Lahore teaching hospital on 50 patients from 5 to 12 years of age. Approval was taken from the ethical board of the institution and informed consent from patient’s parents. Patients who had any other ocular pathology other than refractive errors were excluded. To study the refraction results in children, first in a dark room, retinoscopy without cycloplegic was performed then 1% cyclopentolate eye drops were used. After that retinoscopy was done under cycloplegic effect results were compared after being converted into spherical equivalent. Paired sample t-test was applied to compare means. P < .05 was taken as significant. Results: There were 25 males and 25 females. The mean age in years was 7.66 ±there were 12 myopic patients, 22 hypermetropic and 16 astigmatic patients. The mean logMar of visual acuity uncorrected was 0.5 ± 0.23 and the best corrected visual acuity was 0.1± 0.01. The mean S.E of right eye dynamic retinoscopy was 1.78±2.60, cycloplegic retinoscopy 1.52± 2.54 and of left eye was 1.72±49 and1.47± 2.34 respectively. It can be deduced that on average 0.26D more by dynamic retinoscopy. A significant correlation with r 0.96 and r 0.94 in left eye existed. Conclusion: There is a significant difference between cycloplegic retinoscopy and near retinoscopy. It was deduced that near retinoscopy showed more hypermetropic readings than cycloplegic retinoscopy

This cross sectional study was conducted at the Mayo Hospital Lahore from January 2019 to April 2019 to find out difference and agreement between Bagolini Striated Glasses and Worth Four Dot Test in assessment of fusion and suppression in patients with strabismus. Fifty patients with strabismus, with visual acuity of ≥ 0.6 Log Mar and at least 4 years of age were included. Fusion and suppression were assessed with Bagolini Striated Glasses (BAG) and Worth Four Dot Test (W4DT) at 1/3 meter. Forty-one patients were able to perform W4DT and forty-five patients performed BAG. There were 9 patients who were unable to demonstrate results with W4DT. There were 5 patients who could not demonstrate BAG. Fisher exact test showed 0.570 Exact sig. (2 sided) that exhibited an insignificant difference in the results of the two techniques. Cohen's kappa test showed -0.180 which indicated poor agreement between the two tests.
