2. Macular Degeneration

 Common in elderly individuals

 Can lead to visual loss

 Progression of disease can lead to difficulty reading, driving, or performing activities

of daily living

 Two sub-types of macular degeneration are dry (atrophic) and wet (neo-vascular).

Most cases are dry macular degeneration. If, however, patient has wet macular

degeneration, it is more serious and can lead to blindness in an acute fashion rather

than progressive fashion.

 Quitting smoking reduces the risk of developing macular degeneration and some

studies suggest that diet high in anti-oxidants can be protective. Patients can also

benefit by using a magnifying glass.
