Progesterone treatment shows greater protection in brain vs. retina in a rat model  of middle cerebral artery occlusion: Progesterone receptor levels may play an important role.

CONCLUSION: Inflammatory markers increased in both brain and retina after MCAO, with greater increases observed in brain. Progesterone treatment reduced inflammation, with more dramatic reductions observed in brain than retina. This differential effect may be due to differences in the response of progesterone receptors in brain and retina after injury.
