About 30 years old, there are several yellow spots between the corner of my eyes and my temples, as if I had been burned by cigarette butts. Later, there were many spots on both sides of the nose, the deepest one being eight-shaped. Why? Macula: 0.35cm on the temporal side of the fundus optic disc, slightly below, in the optical center of the human eye, is the projection point of the visual axis.

The macular area is rich in lutein, which is darker than the surrounding retina. The depression in the center of the macula is called fovea, which is the most sensitive place for vision.

The macular retina is thin, the pigment epithelial cells are dense, and the choroidal capillaries behind the retina are dense and the reflection is weak, so the color is dark red. For younger children, the color is reddish brown.
