Is the retina already detached? However, if the retina is already detached, the laser alone is no longer sufficient. Surgery is required. The type of surgery depends on the severity of the triggering cause. A detached retina must be treated immediately, since blindness in the affected eye is imminent after only one or two days.
Is detachment from the retina necessary?
In the latter case, surgery is necessary when the vitreous detaches from the retina. At the moment of detachment, microscopic tears occur in the retina, which are accompanied by a sudden deterioration of visual acuity or flashes of light.
What are possible symptoms before retinal detachment?
Possible symptoms preceding retinal detachment. Possible warning signs of impending retinal detachment include: Flashes of light: Flashes of light occur primarily during jerky eye movements. They are triggered by the vitreous pulling on the retina due to the movement.
What problems can cause the retina?
What problems can cause the retina? The retina of the eye can be affected by various diseases and injuries. Some examples: Macular degeneration: the retina takes damage in the area of the macula (yellow spot). Older people are most often affected (age-related macular degeneration, AMD).
What is a retina of the eye?
The retina of the eye, medically called the retina, is a light-sensitive layer at the back of the eye (2, yellow in the graphic). In its center is the macula (3), the site of sharpest vision. The retina and macula convert the incident light into nerve impulses and transmit them to the optic nerve (4).
Why are fine blood vessels on the retina?
Fine blood vessels at the retina are increasingly attacked by diabetes in the eye. In addition, in premature babies, the vessels in the eye can be damaged and fail to develop properly (retinopathy of prematurity), with oxygen ventilation playing a role.
How to see the retina?
Above you can see the retina as the ophthalmologist sees it when he looks through the wide-drop pupil into the middle of the eye with a special lamp and a magnifying glass (the retinoscopy/ophthalmoscopy) or photographs the retina with a so-called fundus camera as it has been known for a long time.
What is a retina in the eye?
The retina is a layer in the eye that is essential for the visual process. The retina contains the cells that receive light stimuli (photoreceptors, rods and cones). Most diseases of the retina therefore affect vision.
What are the risks for a retinal hole?
Risks for the occurrence of a retinal hole are known cases in the families (genetic causes), severe myopia, injuries to the eye or cataract surgery in the past. How is retinal surgery performed?
Why doesn't the retina reattach?
The retina will not reattach itself without a surgical procedure. A retinal tear or hole in the retina, called a retinal foramen, can, lead to retinal detachment. However, fluid can flow under the retina through the hole and lift it off.
What are the symptoms of retinal tears and holes? Symptoms of retinal tears or retinal holes Flashes of light or spots in the field of vision, so-called "flying gnats," are often signs of a defective retina. When such symptoms appear, a visit to the ophthalmologist is inevitable.
What are the causes of retinal diseases?
The retina is susceptible to disease and sometimes irreparable damage. Some groups of more common causes of retinal diseases can be distinguished. Circulatory problems are responsible for a number of retinal diseases. They are mostly associated with civilization diseases such as arteriosclerosis.
What vascular diseases develop in the retina? Another common retinal vascular disease is retinal vein occlusion, which can be caused by diabetes as well as hypertension, glaucoma, or neuritis. Venous occlusion is caused by arteriosclerosis or clots.
Which hereditary diseases lead to retinal disorders? Other inherited diseases with specific damage to the retina include Best disease and Stargardt disease. Age-related macular degeneration (AMD) is a common disease in which deposits, metabolic disorders and other consequences occur in the central area of the retina.
What can cause inflammation of the retina?
Inflammation of the retina can be caused by viruses, borrelia, fungi and small single-celled parasites, the toxoplasma. Injuries to the retina occur, for example, when the eyeball is bruised or when sharp objects, such as splinters, enter the eye.
How does the treatment of retinal diseases take place?
The treatment of retinal diseases is carried out after the diagnosis and depends on the findings. The retina is used to receive light from outside and convert it into nerve impulses. These are transmitted to the brain via nerve fibers and processed there in the visual center to form an image.
Is a tear in the retina the cause of detachment?
Most often, a tear in the retina is the cause of detachment - this can be caused by aging of the eye. Treatment depends on the severity and progress of the retinal detachment: sometimes treatment with laser and cold probes is enough. But most often surgery is necessary.
What is tear in the retina? In most cases, a tear in the retina is the cause of detachment. The tear can be caused by an injury, for example, or in myopic patients. accidental damage.
How does the retina sit in the eye?
The retina is located on the inside of the eye. It is made up of several cell layers that are very strongly interconnected.
How big is the retina? Function of the retina. It is only a few millimeters in size, sits inside the eye and processes light impulses in a matter of seconds: the retina. Millions of cells work together to ensure that information is transmitted to the brain via the optic nerve.
What is a retina in the human eye? The retina in the human eye is a true marvel. In the smallest space, millions of cells work together tremendously effectively and quickly in the retina of the eye.
What is the density of the retina on the retina?
The macula, the yellow spot. The human eye has a total of 100 million photoreceptors on the retina. The retina has the highest density of photoreceptors in the so-called macula. This is an area of the retina with a diameter of about three to five millimeters.
How can I prevent retinal detachment?
If left untreated, retinal detachment usually progresses and almost always leads to blindness. You can prevent retinal detachment by visiting an ophthalmologist's office as soon as possible at the first sign of retinal damage.
What is the most common form of retinal detachment?
This is the most common form of retinal detachment. It usually occurs in the peripheral area of the retina, mainly because the retina is particularly thin here. The second, much rarer, group of retinal detachments is caused by traction of scarred membranes, in the "jelly" that fills the eye, the vitreous, on the retina.
What is the outer layer of the retina?
The outer layer of the retina contains the retinal pigment epithelium (RPE). This has two essential functions: It is responsible for the absorption of perceived light and acts as a light filter, so to speak.
What are the inner layers of the retina? The outer layers of the retina are those parts that lie closer to the outer wall of the eyeball (bulbus oculi) - in simple terms, towards the skull bone and the orbit. The inner layers, on the other hand, lie closer to the center of the eyeball, i.e. toward the vitreous body (corpus vitreum).
What are the layers of the retina concerning? Regarding the layers of the retina, the side of the retina that is closer to the outer wall of the eyeball is called the outer side. Accordingly, the side closer to the center of the eyeball is referred to as the inner side.
What is a retina?
The retina is the transparent, light-sensitive tissue at the back of the eye. The cornea and lens focus light onto the retina. The central area of the retina is called the macula and contains color-sensitive photoreceptors (light-perceiving photoreceptors) in great density.
How can I examine the retina? The ophthalmologist can examine the retina with different magnifying glasses and devices quite precisely up to the outermost angle. To do this, the patient is first given drops to drip into the eye so that the doctor can look inside better. There are also other search results for "retina" from Blinde Kuh and Frag Finn.
Which cell layers contain the retina? In addition to the sensory cells that are activated by light photons, the retina contains other cell layers that structure and process the visual signals in a variety of ways before they reach the brain via the optic nerve. Where is the retina located? The retina is located on the inside of the eye.
How can ophthalmologists heal the retina?
Even though in most cases only one eye is affected by the changes in the retina, the medical professional should also always check the other eye. Ophthalmologists can successfully treat and thus heal about 95 percent of retinal detachments that begin with a tear.
How does the ophthalmologist recognize retinal disease? The ophthalmologist detects retinal disease during examination of the back of the eye (funduscopy, ophthalmoscopy). He uses a light source and magnifying glass to look through the patient's pupil, which has been dilated with medication. The first changes are constrictions of the blood vessels - the arteries or arterioles.
What is the anatomy of the eye with retina? Anatomy of the eye with retina (schematic): In the "illuminated" area retinal vessels are visible (lighter: arteries, darker: veins) High blood pressure: What is happening in the eye?
How is it possible to visualize the blood vessels in the retina of the eye? Imaging the finest blood vessels in the retina of the eye gives the doctor the opportunity, for example, to determine or detect the stage of the disease at an early stage in the case of elevated blood pressure or diabetes. A number of methods are available to the ophthalmologist for the examination of the retina.
How long does the retinal examination take without eye drops? With this retinal examination without eye drops, you benefit, among other things, from the short duration: You can leave the practice after just a few minutes - and immediately resume driving or operating machinery.
