Introduction
The macula forms a pale yellow area in the center of the retina, approximately 1 to 3 millimeters in diameter. Its distinctive color results from a high concentration of lutein, clearly distinguishing it from the surrounding retinal tissue. This region contains a large number of photoreceptor cells, particularly cone cells responsible for fine vision. The dense packing of these cells makes the macula the central area for visual signal reception.

Under normal circumstances, the macula is located in the central area of the retina inside the eyeball, approximately 3 millimeters temporal to the optic disc. It is the region of the retina with the sharpest visual function. If there are any concerns, it is recommended to seek medical consultation in advance. Detailed analysis is as follows:

The macula forms a pale yellow area on the central retina with a diameter of about 1–3 millimeters. Its distinctive color results from a high concentration of lutein, clearly differentiating it from the surrounding retinal tissue. This region contains a large number of photoreceptor cells, particularly cone cells responsible for detailed vision. The dense packing of these cells makes the macula the core area for receiving visual signals.

The macula primarily processes visual information from the central field of vision, including detail recognition, color discrimination, and perception of object shapes. Daily activities such as reading, writing, using mobile phones, and recognizing faces all depend on the proper functioning of the macula. If the macula develops pathology, central vision can be directly affected, leading to blurred or distorted vision, or defects in the central visual field.

In daily life, avoid staring at bright lights for prolonged periods and reduce screen time on electronic devices to prevent overstimulation of the macula. If symptoms such as decreased central vision or visual distortion occur, prompt evaluation by an ophthalmologist is necessary to check for macular-related conditions and prevent delays in timely intervention.
