Macular degeneration cannot be prevented since it is related to aging. However, getting regular examination can lead to early detection and prompt management. When your macular degeneration is detected early enough, you can exponentially delay the loss of vision. Starting at the age of 40, regular eye examination should be done at least every six months or according to your ophthalmologist's advice. You should expect the eye doctor to do a few different types of eye exams to look for drusen, vessel damage, pigment changes in the retina or visual disturbances.  Some examples of exams to detect visual disturbances are as follows:  Visual acuity test: This tests your vision at a distance using a chart.  Amsler grid: This checks for central vision disturbances by allowing the patient to dictate whether they are viewing straight lines on the grid, or if they appear wavy. Wavy lines indicate macular degeneration.  Dilated eye exam: In this exam, pupils are dilated so allow the doctor to see the optic nerve and retina to evaluate for damage. The doctor will also check the retina for pigment changes.  Pigments in the retina indicate poor light reception.   Fluorescein angiogram: This test will evaluate the arteries in the eye in order to detect leaky vessels. The doctor will inject a dye into the arm a patient’s arm.  Optical coherence tomography: This exam is done after first dilating the eyes.  Then an infrared light is used to image the retina, therefore allowing the examiner to determine damaged areas. Aside from the many destructive effects of smoking on the entire body, it can also lead to macular degeneration. Smoking contains tar that can stimulate the formation of drusen (waste deposits on the eye). In addition to this, smoking contains caffeine which is a known stimulant that can increase blood pressure. The blood vessels beneath the retina and macula can easily burst when blood pressure is high.  Smoking can double your chances of having macular degenerative disease, compared to those who don’t smoke. It's...
