| PVD, which is short for Posterior Vitreous | | | | break down vitreous macro-molecules and |
| Detachment, is a syndrome of eye that vitreous | | | | weaken vitreoretinal adhesion to further mitigate |
| gel separate from the retina, meaning | | | | APVD. This is a safe way to help to prevent the |
| detachment. Vitreous gel is located behind the lens | | | | disease from becoming more serious, especially |

| However, with time goes by, the changes, either | | | | unifying theory. |
