Table 2. BCVA (logMAR) at the pre-lockdown and follow-up visits among the control and delayed groups.

  Pre-Lockdown BCVA (logMAR) Follow up BCVA (logMAR) Significance
Control Group (n = 90) 0.404 0.413 p = 0.70
    nAMD (n = 57) 0.391 0.419 p = 0.20
    DME (n = 30) 0.417 0.449 p = 0.40
    RVO (n = 3) 0.333 0.272 Not significant
Delayed Group (n = 77) 0.631 0.767 p = 0.007
    nAMD (n = 36) 0.729 0.853 p = 0.04
    DME (n = 34) 0.544 0.722 p = 0.06
    RVO (n = 7) 0.555 0.549 Not significant

There was no significant difference between the BCVA at the pre-lockdown (0.404) and follow-up (0.413) in the control group (p = 0.70). BCVA worsened in the delayed group from 0.631 (pre-lockdown) to 0.767 (follow-up). This was statistically significant (p = 0.007). Subgroup analysis was also performed for nAMD and diabetes in both groups and there was a trend towards worsening BCVA in the delayed group.
