Table 4. Comparison of oxygen saturation and vessel diameter in BRVO groups with healthy individuals.
| Central retina | Ischemic BRVO | Control A | P | Non-ischemic BRVO | Control B | P |
| SaO2-V (%) | 62.1±6.0 | 60.3±6.0 | 0.261 | 58.3±8.9 | 60.4±6.4 | 0.465 |
| SaO2-A (%) | 101.3±5.4 | 94.7±5.5 | 0.00003 | 97.4±5.2 | 94.4±5.2 | 0.035 |
| SaO2-AV (%) | 39.1±6.4 | 34.4±5.1 | 0.003 | 39.1±8.8 | 34.1±5.1 | 0.018 |
| VD (pixels) | 16.1±1.2 | 15.9±1.5 | 0.430 | 16.2±1.6 | 16.0±1.4 | 0.958 |
| AD (pixels) | 12.3±1.1 | 13.3±1.2 | 0.001 | 12.9±1.5 | 13.5±1.2 | 0.056 |
Significantly increased SaO2-A and SaO2-AV can be seen in both ischemic and non-ischemic BRVO group (P<0.05). AD in Ischemic BRVO eye was significantly narrower than healthy eye (P<0.05). Data were collected according second kind of analysis in method. Kruskal-Wallis test were performed for comparison, P<0.05 was considered statistically significant.
