Búseta: Athyglisvert er, að enda þótt
ellihrömun í augnbotnum sé Jangalgengasta
orsök lögblindu á Islandi koma fáir sjuklingar
af landsbyggðinni til greiningar og meðferðar.
Hlýtur það að benda til að aðgengi að þessari
þjónustu sé betra í Reykjavík og á Reykjanesi.
Aldur og ellihrörnun í augnbotnum:
Framingham - augnrannsóknin (1973-1975)
er sennilega þekktasta faraldsfræðilega
rannsóknin um ellihrömun í augnbotnum.
Þar var notað þýði úr Framingham -
hjartarannsókninni á aldrinum 52-85 ára.
