Aging of the Whole Retina Experimental Results

In our experiments, only samples of the retinas coming from living humans and not from autopsies were used because post-mortem phenomena may bring about early modifications in the morphometric data obtained from the retinas. Our studies were approved by the local Ethical Committee, and patients or their relatives gave their informed written consent. The investigations were performed according to the guidelines of the Declaration of Helsinki. After removal, the eye-bulb was dissected with a razor blade and samples of intact retinal tissue (located precisely in the same site, equatorially in the nasal region) were harvested. The whole thickness of the retina was measured by a micrometric gauge. Small fragments of the retina were then placed in ice-cold fixative (for morphological staining) or submersed in ice-cold buffer (for estimation of protein content).
