Color Vision01:24

Color Vision

1.4K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.9K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Changes in Skin Color: Clinical Perspectives

3.4K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Area of Science:

  • Ophthalmology
  • Neuro-ophthalmology
  • Genetics

Background:

  • Acquired color vision deficiency arises from ocular, neurologic, or systemic diseases.
  • Conditions affecting color vision span from ocular media to visual cortex pathology.
  • Traditionally distinct from congenital color vision deficiency, emerging data suggest overlap.

Purpose of the Study:

  • To review the pathophysiology of acquired color vision deficiency.
  • To discuss prevalence data and theories for S-mechanism (tritan) deficiency.
  • To examine color vision testing and types encountered in ocular disease.

Main Methods:

  • Literature review of acquired color vision deficiency.
  • Analysis of pathophysiology, prevalence, and genetic overlap.
  • Discussion of diagnostic tests and ocular disease manifestations.

Main Results:

  • Acquired color vision deficiency has diverse etiologies.
  • S-mechanism (tritan) deficiency is often prevalent.
  • Clinical investigations reveal specific patterns in ocular diseases.

Conclusions:

  • Acquired color vision deficiency is a complex condition with varied causes.
  • Understanding pathophysiology and diagnostic methods is crucial.
  • Further research may clarify the relationship with congenital forms.
