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
A basic characteristic of humans is their eye color. Whether brown, blue or green – this is also shown in the passport, among other things. But why do people actually have different eye colors? Iris and pupil The iris or iris skin is the colored part of the eye and is virtually an aperture for … Why do People Have Different Eye Colors?
The pupillometer is a pupillometry instrument that determines the width and light responsiveness of the pupils. Pupillometers are especially important before eye refractive surgery because they can determine the laser range on the cornea. Because pupil width is also relevant from neurological and psychological perspectives, pupillometry also helps these disciplines. What is a pupillometer? A … Pupillometer: Application & Health Benefits
The pupil is significantly involved in the visual process. It regulates the incidence of light on the retina and is thus involved in the formation of the visual impression. Through the process of stimulus processing, it adapts to the prevailing light conditions. What is the pupil? In the eye, the pupil is visible as a … Pupil: Structure, Function & Diseases
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
