The two eye chambers communicate with each other and are filled with aqueous humor, which primarily serves to supply nutrients to … Ocular Chamber: Structure, Function & Diseases
Electroretinogram represents the result of a performed electroretinography, a special functional examination of the retina of the eye. The purpose of the measurement is to check the functionality of the light sensory cells of the retina (cones and rods). The electrical impulses generated by the rods and cones in response to given light stimuli are … Electroretinogram: Treatment, Effect & Risks
Definition The Sturge Weber syndrome, also known as encephalotrigeminal angiomatosis, is a chronically progressive disease from the so-called circle of neurocutaneous phacomatoses. It is a group of diseases of the nervous system and skin characterized by malformations. The Sturge Weber syndrome is characterized by the formation of angiomas (German: Blutschwamm). Angiomas are benign vascular tumors … Sturge Weber Syndrome
Life expectancy Life expectancy does not necessarily have to be limited in Sturge Weber syndrome. If above all the port-wine stain is in the foreground of the disease and there are no drastic accompanying symptoms, the patient is hardly different from a healthy person. The eye diseases associated with the syndrome do not usually change … Life expectancy | Sturge Weber Syndrome
Causes The cause of the Sturge Weber syndrome lies on a genetic level. According to current knowledge, it is a somatic mutation. This means that the disease is not inherited, but is triggered spontaneously by errors in the carrier’s DNA. The sequence of certain compounds in the DNA, so-called base pairs, determines the blueprint of … Causes | Sturge Weber Syndrome
Retinal implants can take over the function of photoreceptors destroyed by retinal degeneration in severely visually impaired or blind people to a certain extent, provided that the optic nerves and visual pathways of the brain are functional. Depending on the degree of destruction of the retina, different techniques are used, some of which use their … Retinal Implant: Treatment, Effect & Risks

Synonyms Medical: retina Introduction The retina is a part of the eye and consists of several layers containing cells that absorb, convert and transmit light stimuli. It is responsible for color and brightness vision and finally forms the optic nerve, which transmits the impulses to the brain. For the different colors and light intensities, the … Retina of the eye
Tasks of the retina The retina of the eye, also known as the retina, is responsible for transmitting stimuli to the brain. It is therefore responsible for ensuring that what we see is perceived as an image. The light must first pass through the cornea, the lens and the vitreous body of the eye before … Tasks of the retina | Retina of the eye
Diseases of the retina In general, diseases of the retina are painless because there are no pain fibers in the retina. A retinal detachment results in a separation of the retina from the choroid, which is rich in vessels. A space is formed in which fluid accumulates. As a result, the retina can no longer … Diseases of the retina | Retina of the eye
What is choroidal neovascularization (CNV)? What is its purpose and In which diseases does it occur? A brief overview follows in this article. What is choroidal neovascularization? Choroidal neovascularization (CNV) is an attempt by the body to bypass an undersupply of oxygen and nutrients to the retina. To do this, the body forms more small … Choroidal Neovascularization: Function, Role & Diseases
