Where is the macula? The macula is located in the center of the retina, the light-sensitive tissue at the back of the eye. The retina immediately converts light or images into electrical impulses, and then transmits these impulses, or nerve signals, to the brain to form vision. What are the different types? There are two types: dry and wet. What is wet AMD? Wet AMD occurs when there is abnormal growth of new blood vessels behind the retina in the macula. these new blood vessels are fragile and prone to hemorrhage and fluid leakage, which can lead to edema and bulging of the macula, which can quickly lead to destruction of the macula. As wet AMD progresses, rapid loss of central vision occurs. Wet AMD is an advanced form of AMD that is more severe than dry AMD. An early symptom of wet AMD is distorted vision. If your vision changes in this or any other way, you should see an ophthalmologist immediately, and you will need a thorough and detailed eye exam. What is dry AMD? Dry AMD occurs when the photoreceptor cells in the macula of the affected eye are slowly destroyed, gradually blurring central vision. As dry AMD worsens, a dark spot appears in the center of your field of vision. Over time, the macula decreases in function and the center of the affected eye loses vision. The most common symptom of dry AMD is a slight blurring of vision. You may have difficulty recognizing faces and need more light to read or do other things. Dry AMD usually affects both eyes, but it is possible to have vision loss in one eye without the other appearing to be affected. How can AMD be detected? AMD can be detected with a comprehensive eye examination, which may include: Visual acuity examination: A visual acuity chart to measure how well you can see at different distances. Dilated Pupil Exam: Dilated eye drops dilate your pupils, and your eye doctor uses a special magnifying glass to look at your retina and optic nerve to look for signs of AMD and other eye diseases. It is normal for your pupils to dilate and blur your vision for a few hours after the exam. Intraocular Pressure (IOP) Measurement: An instrument is used to measure the pressure inside the eye.
