Age-Related Macular Degeneration (ARMD) is a progressive deterioration of the macula, an oval area at the center of the retina that helps us see details clearly. As the name suggests, this is a more prevalent disease with our aging population. Symptoms include blurred vision and gradual deterioration of the centre of the field of vision. It is not accompanied with any pain or other warnings.
Anti-histamines (Benadryl, Dimetane, others) causes an increase in pressure in the eyes and should be avoided by people with glaucoma.
Diuretics such as Chlorothiazide (Diuril) and Furosemide (Lasix) can cause dryness and blurred vision.
Plaquenil used in arthritis, lupus and malaria can reduce your ability to see the colour red and can cause a distortion of the central vision. Lines that are straight may look wavy, making reading difficult.
