A comprehensive eye examination is necessary to diagnose Macular Degeneration (AMD) which includes refraction and vision examination, dilated eye exam, an Amsler’s grid and angiography with the use of an optical coherence tomography (OCT).
During the eye examination, your ophthalmologist may ask you to look at an Amsler grid. This grid helps you notice any blurry or blank spots in your field of vision.
Your ophthalmologist may put drops in your eye to dilate (widen) your pupil. He or she will also look inside your eye through a special lens whereby they can see if there are changes in the retina and macula.
Your doctor may do a non-invasive angiography to see what is happening with your retinal blood flow. This scan will show if abnormal new blood vessels are growing under the retina.
A normal OCT scan is another method to look at the retina and its blood flow. A machine scans the retina and provides very detailed images of the retina and macula.
