Graft characteristics and post-storage ‘corrected ECD’ in grafts stored as collapsed bubbles or free scrolls
| Free scroll OD (n=8) | Liquid bubble OS (n=8) | p Value | |
|---|---|---|---|
| Donor age | 65.4±10.3 years | 65.4±10.3 years | |
| ECD±SD (specular) | 2667±221 cells/mm2 | 2754±200 cells/mm2 | |
| Death to storage time | 6.2±4.1 hours | 6.2±4.1 hours | |
| Cause of death | Trauma (4) Subarachnoid haemorrhage (1) Myocardial infarction (3) | Trauma (4) Subarachnoid haemorrhage (1) Myocardial infarction (3) | |
| Donors with diabetes | 1 (in myocardial infarction group) | 1 (in myocardial infarction group) | |
| Corrected graft area±SD | 58.1±0.51 mm2 | 59.4±0.73 mm2 | |
| Corrected global ECD±SD | 74.2±3% | 60.3±6% | 0.035 |
Tissue was from paired donors. Global viability was calculated by counting all viable cells on the graft and dividing this value by the graft area (adjusted for imaging a spherical cap). This figure was presented as a percentage of the starting central ECD measured in the eye bank – corrected global ECD.
ECD, endothelial cell density; OD, oculus dexter; OS, oculus sinister.
