Degeneration of the macula is the leading cause of legal blindness
in people over fifty-five. The macula is an integral piece of the
retina; we use it for our most acute and detailed vision --
reading, driving, watching television, precise work, and
recognising faces. However, this weakening of central vision does
not necessarily affect colour and peripheral vision. Macular
degeneration generally takes place over a gradual period and at
different rates in each eye. Its causes are still unclear, but we
do know of two types. 'Dry' degeneration occurs when the macular
tissues of the retina thin and disturb pigmentation, and 'wet'
includes bleeding and scar tissue. Though macular degeneration is
usually age-related, there are forms that affect younger
individuals, but the reasons behind those cases are not yet known.
This new book provides a review of this debilitating condition and
the state of current medical research on macular degeneration.
Following the overview are carefully selected abstracts of the
relevant literature with easy access via title, subject, and author
indexes.
