Thanks Bernie Mike,

Most of the retina essentially can be considered gray matter. Other parts of the eye (e.g., the sclera) have their embryological genesis in other tissue. The Diving Research Centre (DDRC) at Fort Bovisand, which is still quite active, did have an extraordinarily productive research program on the effects of aviation and diving on the body back in the 80s, although I am not familiar with the particular study you mention. Thanks for your contribution. Regards, DocVikingo Hi BillA,

In 1988 a research doctor from Fort Bovisand in the UK told me of an experiment done there, presumably in the 80s in which a sample of people who had never dived were taken down in a chambre to a modest depth and time well below anything approaching deco and then had the capillaries in their eye examined. There was permanent damage to all from one exposure - or so I was told/recall. This has thought-provoking implications because if I remember my embryology correctly, the eye develops as a direct outgrowth of the brain. This is from memory and needs verification.
