The vitreous is a gel-like material attached to the retina at several points along the back of the eye. If the vitreous becomes detached from the retina, it could have no effects, it could cause flashing lights or floaters or it could create a...
The posterior portion of the human eye contains a jelly-like material called the vitreous. The vitreous has multiple attachment points on the retina, which is a thin layer of cells responsible for gathering visual images, according to the Academy...
Being diagnosed with any kind of serious eye problem can be frightening. You start having symptoms, you make the appointment, the doctor pours a ton of drops into your eyes then blinds you with bright light. He spouts off some mumbo jumbo medical...
Eye floaters are dark lines or shapes that appear in your field of vision. Floaters usually move about with eye movement and then float away when the movement stops. For most individuals, these are a normal occurrence and no treatment is required....
The retina is nerve tissue that lines the inner portion of the eye. The function of the retina is to sense light and relay nerve impulses through the optic nerve to the brain. Conditions may occur that cause the retina to detach or pull away from...
The University of Maryland Medical Center defines sudden retinal detachment as the separation of the retina from its supporting layers. The retina is the light-sensitive transparent membrane at the back of the eye where images seen are formed....
Vision problems are one of the most common complications of diabetes. The longer a person has diabetes, the more likely he will develop a complication with his eyes. Although total blindness is rare and occurs in less than 2% of diabetics, the...
Eye floaters appear as tiny spots, specks and flecks that drift aimlessly around in a person's field of vision. Undissolved vitreous gel particles inside the eye cause floaters and floaters tend to occur more often as a person ages. Floaters come...
The retina consists of light-sensitive tissue that lines the back of the eye. Because the retina contains the rods and cones essential for vision, any disorder that disrupts the tissue can result in vision loss. Two disorders can cause flashes:...
Floaters--annoying but often benign visual disturbances--occur commonly as people age. Floaters appear as small strings or dots that move quickly when a person tries to focus on them, and are easiest to see when looking at a white wall or other...
Many conditions cause photopsia, or flashes of light in the eye. Flashes of light can be harmless or an indicator of a serious eye problem that needs immediate treatment. Flashes accompanied by vision loss or by a large number of floaters, small...
The retina is the delicate membrane that coats the eye where the optic nerve enters, receiving the light that begins the process of vision. The retina sends nerve impulses to the brain to be interpreted into the images we see. Untreated retinal...
The retina, which lines the inside, back portion of the eye, responds to light entering the eye, and thus plays a vital role in vision. Changes in the retina may cause flashes of light in any area of vision, though commonly in the side vision....
Macular pucker is the wrinkling of the retina, the layers of cells lining the back of the eye that are responsible for vision. They're in the area of the macula, the central point of clear vision on the retina. Macular pucker is also known as...
Eye floaters can be a highly annoying visual disturbance. Most of the time, a few floaters in your line of vision aren't harmful, but occasionally floaters, especially if they're large, numerous and develop suddenly, can be a sign of a problem in...
Floaters are tiny specks, dots, squiggly strands or other shapes that appear to float across the visual field. According to the National Eye Institute, they occur when the gel-like vitreous shrinks and becomes stringy strands that create shadows...
Eye flashes, a type of visual disturbance, occur when the vitreous gel within the eye liquifies and pulls away from the retina. This condition can happen naturally with age, and is called posterior vitreous detachment. The retina is responsible...
Everyone experiences those annoying shadowy fibers and dots that float across the field of vision. Or perhaps you see flashes of light or starbursts when you move your head quickly or while exercising. Eye floaters and flashers are common, and...
Fuchs' dystrophy, Fuchs' heterochromic uveitis and Fuchs' spots are three different types of eye diseases all named for the same man, Ernst Fuchs. He was a Viennese professor in the early 1900s who described and named the three ocular diseases now...
Retinal detachment is a serious condition that can lead to severe, permanent vision loss. The retina is area of the eye that lines the back of the eye. The retina contains sensors that transmit vision signals to the brain. Damage to a small area...
Visual disorders are the result of an interruption of the processing of images through the cornea to the retina and optic nerve and then to the brain for interpretation. Congenital defects, injury and age affect the ability to see clearly. Eye...
Floaters are specks or spots that float around in the visual field. The National Eye Institute describes them as "cobwebs" or small, dark shapes that look like squiggly lines that seem to dart away when you look directly at them. The Mayo Clinic...
Auras are visual manifestations of neurological symptoms. Flashing lights are one type of aura people report seeing, and these auras often seem to appear in either the left or the right eye. Migraines are a common cause of visual disturbances,...
The phenomenon known as vitreous "floaters," or eye floaters, is precisely what it sounds like--the appearance of small, dark or squirmy dots that float across your field of vision. According to HealthierTalk.com, floaters are usually caused by...
The retina is a thin, light-sensitive membrane covering the back of the eyeball and further attached to the optic nerve. As we perceive images, the retina converts these images into electrical impulses and sends them to the brain via the optic...
Eye health is an important concern at any age, but especially for children. As kids' eyes grow and develop, changes occur that can permanently affect their eyesight. Paying close attention to any changes in their vision is important to prevent...
Eye pressure, or intraocular pressure, is caused by increased aqueous fluid buildup in the eye. Normal eye pressure is 11 to 21 mmHg, according to the Merck Manual. An abnormal rise in eye pressure that damages the optic nerve is called glaucoma....
Systemic lupus erythematosus is a chronic autoimmune disorder that occurs predominantly in young women. SLE causes inflammation and damage in different areas of the body and is a disease of flare-ups and remissions. Treatment typically involves...
The retina is a layer of cells located at the rear of the eye that takes light rays that enter the eye and changes them into visual impulses. This layer of cells can be affected by several conditions that can impact the vision of the patient. Many...
