Retinal microenvironment imbalance in dry age-related macular degeneration: a mini-review.

abstract：:Hyposplenism has been reported in elderly people. However, from previous studies, it was not clear whether the observed alterations in splenic function were a physiologic effect of advanced age itself or a consequence of age-related diseases. As hyposplenism is believed to predispose to infections, autoimmune phenomen...
