Patient's question:
My sister-in-law's daughter is a premature baby. The doctor checked and said the child's eyes are underdeveloped, but there's no problem with the macula, so there's nothing to worry about. What is the macula?Doctor's answer:
Hello, it should be the macula, right?Macula: Located at 0.35 cm temporally and slightly inferior to the optic disc in the fundus, it is within the optical center of the human eye and serves as the projection point of the visual axis. The macular area is rich in lutein and appears slightly darker in color than the surrounding retina. The central depression in the macula is called the fovea, which is the most acute point of vision. The retinal tissue in the macular area is relatively thin, with dense retinal pigment epithelial cells. The choroidal capillaries behind the retina are densely packed, resulting in weaker reflection, giving the area a dark red color. In younger children, the color appears reddish-brown.
Since the macula is at the optical center of the human eye, the target being stared at is projected onto the fovea of the macular area. Generally, a visual examination of the human eye checks the visual function of the macular area. The vision outside the macular area is extremely low. When a person dies or the eyeball detaches from the body, the macula appears pale yellow, hence its name.
