Age-related macular degeneration (also known as age-related macular degeneration or senile macular degeneration) is a degenerative disease that occurs with age, mostly in older people over the age of 50, and is now being diagnosed in increasing numbers. What exactly is macular degeneration? What is macular degeneration and where does it grow? We would like to discuss these questions with you here. The human eye is often compared to a perfect camera, the “film” of the human eye is the retina at the back of the eye, the beauty of the world is imaged on the retina through the eye, and then perceived by the human brain. It is the most sensitive part of our visual function, so when this area develops a series of lesions with age, our vision will be greatly affected. You may still find it too abstract because normally we have no way to see the retina and macula directly, after all, they are both internal structures of the eye, but it’s okay, let’s take a look at what the doctor sees when he examines the patient’s eye? Patients who have been to the eye specialist clinic will know that every time the doctor will tell the patient to sit in front of a microscope-like instrument called a slit lamp, the doctor will examine the patient’s eye through it. When the doctor puts a small lens in front of the patient’s eye, he or she can see the inside of the eye, which is professionally known as a fundus examination. The sketch below is an overall overview of the fundus retina (right eye, patient facing the reader), which is basically the image of the fundus as seen by the doctor.
