Table 3. Mean values of visual function at baseline and follow up based on age category (below and above age 50 years).

Age	Below 50	Over 50	P-value
Baseline logMAR Visual Acuity	0.69 ± 0.66	0.87 ± 0.72	0.17
Follow up logMAR Visual Acuity	0.55 ± 0.57	0.90 ± 0.73	0.03 *
Baseline Visual Field MD	-14.13 ± 8.7	-16 ± 9.26	0.35
Follow up Visual Field MD	-11.52 ± 6.50	-14.85 ± 6.70	0.10

• P-value ≤0.05 is statistically significant.
