Changes in ED1 positive cells in the choroid following systemic lipopolysaccharide injection
| 4 and 8 hours | Increased number of round cells, occasionally accompanied by an increase of dendritiform cells |
| 16 hours | A tremendous number of round cells, diffusely present in the whole area of the choroid with focal accumulation |
| 24 hours | Round cells decreased in number, dendritiform cells numbers increased |
| 48, 72, and 96 hours | A large number of dendritiform cells with more and longer dendrites and a larger but vague cell body was present, accompanied by a decrease of pleiomorphic cells |
| 7, 10, and 14 days | Both dendritiform cell and pleiomorphic cell numbers decreased and gradually returned to preinjection level |
