Visual Acuity of the Studied Cases at Baseline, One Month, and Three Months (n=30)

VA	Initial	Follow-Up		Fr	p
		One Month	Three Months
Mean ± SD.	0 ± 0	0.1 ± 0.1	0.2 ± 0.2	20.0*	<0.001*
Median (Min. – Max.)	0 (0–0.1)	0.1(0–0.3)	0.3(0–0.5)
Sig.bet.periods	p1=0.005*, p2<0.001*, p3=0.889

Notes: Fr: Friedman test, Sig. bet. periods was done using post hoc test (Dunn’s). p: p value for comparing between the three periods. p₁: p value for comparing between initial and one month. p₂: p value for comparing between initial and three months. p₃: p value for comparing between one month and three months. *Statistically significant at p ≤ 0.05.
