The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.

The retina is a key bridge between the light that enters your eyes and the images you see. Special cells in your retina react to light and pass signals to your brain that let you see the world around you. Talk to your eye care specialist if you notice gradual vision changes.

Aug 8, 2023 · The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture.

The normal central retinal artery (black arrow) is located nasal to the central retinal vein (green arrow) in the optic disc. The normal ratio of diameter of a retinal vein to a retinal artery at a given distance from the center of the optic disc is approximately 1.3:1.

Sep 8, 2020 · The retina is the layer of cells lining the back wall inside the eye. This layer senses light and sends signals to the brain so you can see. Several parts of the eye are associated with the retina. They include: Read an overview of general eye anatomy to learn how the parts of the eye work together.

Oct 9, 2024 · The retina senses light and generates electrical impulses so the brain can create an image. This article discusses the retina’s anatomy, functions, and associated disorders. It also covers the fundamental anatomy of the eye and how the retina works with other primary structures. Anatomy of the Retina

Retinal disease is a leading cause of blindness and early detection is the game changer. Here’s how to safeguard your sight: Be aware of your risk factors, which may include age, family history or pre-existing health conditions.

May 1, 2005 · The retina is approximately 0.5 mm thick and lines the back of the eye. The optic nerve contains the ganglion cell axons running to the brain and, additionally, incoming blood vessels that open into the retina to vascularize the retinal layers and neurons (Fig. 2).

Figure 35.1a shows a raw retinal image containing cone structure (object) and the Gaussian beam profile, CCD circuit and dust (noise). A background correction procedure was developed to correct these artifacts.

Common Imaging Techniques and Technologies Used by Retina Specialists , and blood vessels. During the exam, the retina specialist shines a bright light into the eye from a special head-mounted device. The retina specialist then uses another lens, called a handheld lens, to magnify the image of the back of the eye and
