Most people have heard of the retina, but do they really know what this part of the eye is and what it does? The retina is a tissue that lines the inside of the eye. This tissue is light sensitive, which is vital for sight. The retina itself is made of multiple layers of neurons. The photoreceptor cells, which are commonly referred to as rods and cones, are the only neurons that are light sensitive. The rods and cones act as receptors that send information to the other neurons to process light.
How the Retina Sees
Other parts of the eye take in light, which forms an image projected on the retina. In a way, it could be viewed like a projector and a movie screen. The world projects images and the retina captures them for the eye and brain to process. The optic nerve serves as a link between the eye and the brain, so the images get to the right places.
Retina Health and Risks
Just like any other part of the body, the retina is susceptible to certain diseases and conditions. Since the retina plays an integral role in the sense of sight, a problem can hinder the patient’s ability to see and process images. Some conditions are inherited. For example, Retinitis pigmentosa develops as a result of genetics. This term refers to an entire group of diseases that impact the retina and lead to a loss of peripheral and night vision. Retinoblastoma refers to cancer that develops in the retina while macular degeneration causes central vision blindness.
Treating Retina Conditions
Retina conditions are caused by many different things. In order to treat a retina problem, the individual condition must be evaluated. If you suspect a problem with your eyes, make an appointment with a physician right away. Only a trained medical professional can accurately diagnose the problem and provide a safe treatment plan.
Your retina is a very important part of your eyes. Without the retina, the entire process of seeing would be hindered. Have problems checked out as soon as you notice a change in your eyes. You may be able to correct the problem or find a way to live with it.
