Color Vision01:24

Color Vision

654
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.

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

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...

Special Staining Techniques

191
Specialized staining techniques play a vital role in microbiology by enabling the visualization of specific bacterial structures that remain undetectable with standard microscopy methods. These techniques not only enhance the structural visualization of bacterial cells but also provide critical insights into their pathogenicity and classification. Additionally, they support diagnostic and research endeavors in microbiology by identifying key bacterial features.Capsule Staining for Virulence...

Changes in Skin Color: Clinical Perspectives

2.1K
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...

Position-effect Variegation

6.5K
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Area of Science:

  • Ophthalmology
  • Medical Illustration
  • Retinal Imaging

Background:

  • Current color-coding systems for retinal drawings standardize the representation of common fundus findings.
  • These systems effectively depict preretinal, intraretinal, and subretinal lesions for clinical interpretation.
  • Advancements in retinal imaging modalities have deepened the understanding of microanatomy and associated pathologies.

Purpose of the Study:

  • To highlight the limitations of existing color-coding systems in representing newly understood retinal pathologies.
  • To discuss the need for developing a more precise color-coding system for detailed fundus representations.
  • To address the challenges in clinically representing minute details of retinal findings.

Main Methods:

  • Review of common retinal pathologies across different retinal layers.
  • Analysis of current color-coding conventions for fundus drawings.
  • Discussion of discrepancies between detailed pathology and existing color-coding capabilities.

Main Results:

  • Existing color-coding systems are insufficient for the precise representation of subtle retinal pathologies.
  • Newer imaging techniques reveal details that current color codes cannot adequately capture.
  • A 'color-coding dilemma' exists when trying to precisely depict complex, layered retinal findings.

Conclusions:

  • There is a clear need for updated and more precise color-coding systems in retinal drawing.
  • Enhanced color-coding is crucial for accurate clinical representation and interpretation of advanced retinal imaging findings.
  • Developing a refined system will improve diagnostic accuracy and communication of retinal conditions.
