Correlation of the presence of episcleral vessels entering sclerotomies and FVI
| Case No | FVI >1 clock hour* or previous VCWO† | Episcleral sclerotomy vessel | Operative findings: site of FVI | Time of haemorrhage (weeks) | Preop vision | Postop vision |
| 1 | none | SN | 99 | LP | 3/60 | |
| 2 | † | SN+ST | All ports | 6 | HM | 6/60 |
| 3 | * | SN | SN>ST | 8 | LP | 6/18 |
| 4 | * | ST | ST | 13 | HM | 6/24 |
| 5 | * | none | SN+ST | 2 | LP | |
| 6 | †† | SN+ST | SN+ST | 4 | LP | CF |
| 7 | SN | ST | 38 | LP | 6/36 | |
| 8 | SN | SN | 0 | HM | ||
| 9 | † | none | SN+ST | 129 | LP | 6/24 |
| 10 | none | SN | 0 | HM | 6/9 | |
| 11 | SN+IT | All ports | 2 | HM | 4/36 |
SN = superonasal, ST = superotemporal, IT = inferotemporal, HM = hand movement, LP = light perception, CF = counting fingers.
In cases 2, 6, and 9 with six or nine entry sites as a result of previous VCWOs in addition to initial vitrectomy the quadrant was inspected and not individual sclerotomies.
