Table 2 Random numbers of retinal vessels branch from the optic disc. The number and patterning of the retinal vessels was examined in 150 retinas from ~100 adult wild type zebrafish. Most of the retinas (64%) exhibit 6 or 7 main branches radiating from the optic disc, although the number of vessels varies from 4 to 9. In some individuals (n = 21), the retina from the left eye was compared to the retina from the right, showing no apparent correlation between anatomical location and the number of main branches.

Number of branches | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|
Retinas (n = 150) | 7% | 23% | 39% | 25% | 5% | 1% |
Left retinas (n = 21) | 10% | 33% | 23% | 29% | 0% | 5% |
Right retinas (n = 21) | 0% | 38% | 38% | 14% | 10% | 0% |
