Glaucoma among Cayleys

One specialist use of genealogy is medical – to get information on family patterns for diseases etc. This is especially important for rare genetically-caused conditions, for which genealogical information can be valuable to researchers and medics. But genes can cause, or make people susceptible to, many more common conditions. Among them is glaucoma, which – it has been known for many years – tends to run in families.

One family is my own, on both my maternal and my paternal side. Among the Cayleys in my family, my paternal grandfather, my father and my brother all had or have glaucoma. Are there other Cayley families in which glaucoma runs?

And are there other medical conditions which are associated with any Cayley families?
