Nägemisretina

Nägemisretina, also known as the retina, is a thin layer of tissue that lines the back of the eye. It is responsible for converting light into electrical signals that the brain interprets as images. The retina contains several types of photoreceptor cells, including rods and cones, which are crucial for vision. Rods are responsible for low-light vision and are more numerous in the peripheral regions of the retina. Cones, on the other hand, are responsible for color vision and are concentrated in the fovea, the central part of the retina where visual acuity is highest.

The retina also contains other types of cells, such as bipolar cells, horizontal cells, and ganglion cells, which process and transmit visual information to the brain via the optic nerve. The retina is innervated by the retinal blood supply, which ensures its proper functioning and nutrition.

Nägemisretina is a critical component of the visual system, and any damage or disease affecting the retina can lead to vision loss or impairment. Common retinal conditions include macular degeneration, diabetic retinopathy, and retinal detachment. Advances in medical technology and surgical techniques have improved the diagnosis and treatment of retinal diseases, offering hope for better visual outcomes for patients.
