Table 4. Comparison of total retinal thickness of the macular region and of the temporal retina between sickle cell disease eyes and control subjects.
| ETDRS grid quadrant | Thickness (μm) | |||
|---|---|---|---|---|
| SCD subjects (n = 59) | Controls (n = 59) | p-value | ||
| Macula | Fovea | 267.2 | 282.7 | <0.0001 |

| Nasal | 325.8 | 337.4 | <0.0001 | |
| Superior | 316.6 | 328.9 | <0.0001 | |
| Temporal | 298.7 | 312.0 | <0.0001 | |
| Temporal Retina* | Inferior | 232.6 | 240.9 | 0.0017 |
| Superior | 236.3 | 241.0 | 0.0114 | |
| Temporal | 215.8 | 224.0 | 0.0006 | |
SCD, sickle cell disease.
*Thickness data from the nasal quadrant of the temporally-centered grid were not collected because of overlapping with the temporal quadrant of the fovea-centered grid
