Retinal spot

The retinal spot (macula, pna; macula lutea, bna, jna; synonym yellow spot) is the area of ​​the retina in the posterior pole with the greatest visual acuity. It is located in the center of the macula and has a diameter of about 1.5 mm.

The retinal spot has an increased density of photoreceptors (cones and rods), which ensures maximum central visual acuity. This allows you to clearly distinguish the details of objects when looking at them directly. In addition, there are no blood vessels in the retinal spot so that they do not interfere with the passage of light.

Diseases and damage to the retinal spot, such as age-related macular degeneration, can lead to a significant decrease in visual acuity. Therefore, it is important to undergo regular examinations with an ophthalmologist for timely diagnosis and treatment of diseases of this area of ​​the retina.
