What is the optic nerve? Like the retina, the optic nerve is part of the brain. It is about four to five centimeters long and begins at the optic disc in the eye (discus nervi optici). This is a whitish, disc-shaped area at the back of the eye where the nerve endings of the retina … Optic nerve: Function and structure
The best-known form of scanning laser polarimetry is GDx scanning laser polarimetry, which is used in ophthalmology to diagnose and monitor cataracts and allows this disease to be diagnosed up to five years earlier than any previous measurement method. Polarimetry makes use of the polarization property of light by means of a laser scanner and … Scanning Laser Polarimetry: Treatment, Effect & Risks
The optic nerve is responsible for making it possible for people to recognize their environment. Thus, it is one of the most important parts of the eyes. At the same time, different diseases can limit the function of the optic nerve. What is the optic nerve? The optic nerve is made up of nerve fibers. … Optic Nerve: Structure, Function & Diseases
Definition The inflammation of the optic nerve is called neuritis nervi optici. The optic nerve is the second cranial nerve, i.e. it is part of the central nervous system, the brain. It begins at the retina of the eye and transmits the information received by the eye to the brain. For this reason, the disease … Inflammation of the optic nerve
Therapy In most cases an inflammation of the optic nerve shows spontaneous healing even without therapy and the visual acuity improves again by itself. However, the underlying disease should still be identified in order to treat it. About two thirds of those affected have multiple sclerosis, which cannot be cured, but the symptoms can be … Therapy | Inflammation of the optic nerve
Definition The papilla is an area on the retina of the eye. This is where all the nerve fibers of the retina converge and leave the eyeball as a bundled nerve cord in order to be able to transmit the sensory impressions of the eye to the brain. Anatomy The papilla is a circular area … Papilla
Papilloedema Papilledema, also called congestion pupil, is a pathological bulge of the optic nerve head, which is normally slightly convex. Unlike optic disc excavation, pressure from behind on the optic nerve is increased, causing it to bulge forward. The causes of papilledema can be very diverse. In addition to the optic nerve, numerous arteries and … Papilloedema | Papilla
Function of the cranial nerves What exactly do the brain nerves actually do, why do we need them? In short: They conduct the sensations of our sense organs, i.e. what we see (II), hear (VIII), taste (VII, IX, X), smell (I), feel in the area of the head (V), information of our sense of balance … Function of the cranial nerves | Brain Nerves
Common diseases In view of the diverse functions of our cranial nerves, there are theoretically typical symptoms or diseases for each of them (see table). Often, however, certain combinations of failures occur, such asB. Damage to IX, X and XI because they are close together at the base of the skull and run through a … Common diseases | Brain Nerves

For practical … Brain Nerves
Pupillary Reflex The adaptation of the pupil to the prevailing light situation is achieved by the so-called pupillary reflex. A distinction is made between the part that receives the information about the exposure and transmits it to the central nervous system (afference) and the part that, after processing this information, leads to the activation of … Pupillary Reflex | Pupil
What can dilated pupils indicate? In darkness, the pupils are dilated to allow as much light as possible to enter the eye. The so-called sympathetic nervous system dilates the pupils. It is particularly active during stress reactions and also increases pulse and blood pressure, for example. In stressful situations, the pupils can dilate accordingly. A … What can dilated pupils indicate? | Pupil
