Steady-state morphometric measurements of conjunctival vessels in SCD
| Experimental subjects . | Total length of arterioles per area, cm−1 . | Total length of venules per area, cm−1 . | A/V ratio . | Diameter of venules, μm . | ||
|---|---|---|---|---|---|---|
| Group 1: nonsevere SCD (n = 2) . | Group 2: nonsevere SCD (n = 6), severe SCD (n = 6) . | Group 3: nonsevere SCD (n = 3), severe SCD (n = 1) . | ||||
| SCD (n = 18) | 22.4 ± 8.7 | 24.6 ± 6.3 | About 1:1 | 49 and 52 | 79 ± 15 | 40 ± 6 |
| Non-SCD controls (n = 18) | 26.8 ± 3.1 | 49.2 ± 6.7 | About 1:2 | 55 ± 4 | ||
