retinavæv

Retinavæv, also known as the retina, is a thin layer of neural tissue located at the back of the eye. It is responsible for converting light into electrical signals that are sent to the brain via the optic nerve, allowing us to perceive images. The retina consists of several layers, each with distinct functions. The outermost layer is the pigment epithelium, which contains melanin and helps to absorb stray light. Beneath this is the photoreceptor layer, which contains rod and cone cells that detect light and color. The bipolar cells and horizontal cells form the next layer, transmitting signals from the photoreceptors to the ganglion cells. The ganglion cells are the final layer, sending signals to the brain through the optic nerve. The retina is crucial for vision, and any damage to this layer can lead to vision loss. Conditions such as macular degeneration, diabetic retinopathy, and retinal detachment can affect the retinavæv, highlighting its importance in maintaining visual function.
