Table 3 Demographic, clinical and optical coherence tomography (OCT) finding comparisons between the two study groups at the time of injection and at 1 year post commencement of treatment:
Early treatment group (n = 94) | Delayed treatment group (n = 15) | P value | |
|---|---|---|---|
Worsening in DR severity at least by 1 step at the end of 1 year (n, %) | 13 (14) | 4 (27) | 0.247 |
Mean VA (ETDRS letters) at the time of injection | 49.74 ± 16.3 | 56.27 ± 15.2 | 0.003 |
Mean CSFT at the time of injection | 527.2 ± 143.7 | 462.5 ± 73.57 | < 0.001 |
Mean VA (ETDRS letters) 1-year after treatment | 57.38 ± 20.01 | 51.4 ± 12.67 | 0.170 |
Mean change in VA (ETDRS letters) at the end of 1 year | 7.638 ± 17.96 | -6.867 ± 11.65 | 0.001 |
Mean CSFT 1-year after treatment | 422.6 ± 158.9 | 477.8 ± 92.94 | 0.846 |
