2024年10月3日 · What is the retina of the eye? The retina is a layer of cells at the back of your eyeball that converts light into nerve signals. It then sends those signals along your optic nerve to your brain. Your brain processes those signals into your sense of vision.

2024年3月8日 · Retinal diseases can affect any part of your retina, a thin layer of tissue on the inside back wall of the eye. The retina contains millions of light-sensitive cells, called rods and cones, and other nerve cells that receive and organize visual information.

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.

2020年9月8日 · 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: Peripheral retina; …

2025年1月24日 · The retina is actually an extension of the brain, formed embryonically from neural tissue and connected to the brain proper by the optic nerve. The retina is a complex transparent tissue consisting of several layers, only one of which contains light-sensitive photoreceptor cells.

2023年8月8日 · 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 retina is a layer of nerve cells responsible for vision. There are many diseases that affect the retina. While macular degeneration and diabetes are frequent causes of retinal disease, other causes include genetic mutations, immune dysfunction, nutritional deficiencies, and toxicities.

2024年10月9日 · 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 …

2024年9月20日 · What Is the Retina? The retina is the layer of cells positioned at the back of your eyeball. This layer senses the light that comes into your eyeball and sends signals to your brain. The key...

2019年2月26日 · The retina is the sensory membrane that lines the inner surface of the back of the eyeball. It's composed of several layers, including one that contains specialized cells called photoreceptors. There are two types of photoreceptor cells in the human eye — rods and cones.
