Understanding the Postretinal and Preretinal Regions of the Retina

Postretinal refers to the part of the retina that is located behind the retinal vein. This area is also known as the peripheral retina or the outer retina. The postretinal region is responsible for detecting movement and colors, and it plays a critical role in our ability to see clearly.

In contrast, the preretinal region, which is located in front of the retinal vein, is responsible for processing visual information and sending it to the brain. The preretinal region includes the layer of cells called the ganglion cell layer, as well as the optic nerve fibers that carry visual information from the eye to the brain.

Overall, the postretinal and preretinal regions work together to allow us to see and interpret visual stimuli. Damage to either of these regions can lead to vision loss or other visual impairments.
