Pigmentation01:19

Pigmentation

2.5K
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...

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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.4K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Photoreceptors and Plant Responses to Light

22.7K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Summary

Photosensitivity is very common in albinism, affecting over 77% of patients. Neutral, low-transmission filters are preferred to manage light sensitivity and improve vision.

Area of Science:

  • Ophthalmology
  • Genetics

Background:

  • Albinism is a group of genetic disorders characterized by a lack of pigment.
  • Photosensitivity is a common and often debilitating symptom in individuals with albinism.

Purpose of the Study:

  • To determine the prevalence and severity of photosensitivity in albinism.
  • To correlate photosensitivity with ocular features.
  • To evaluate the use and choice of optical filters for managing photosensitivity.

Main Methods:

  • A cross-sectional study involving 81 participants with albinism.
  • Ophthalmic evaluations included visual acuity, contrast sensitivity, iris translucency, and fundus hypopigmentation.
  • Participants underwent optical rehabilitation with various filters, and associations were analyzed.

Main Results:

  • 77.8% of participants reported significant photosensitivity.
  • Photosensitivity severity correlated with fundus hypopigmentation and poorer visual acuity.
  • Neutral-colored filters with low light transmission were preferred, with many participants owning multiple pairs of spectacles.

Conclusions:

  • Photosensitivity is highly prevalent in albinism, necessitating targeted research and management strategies.
  • Optical filters, particularly neutral and low-transmission types, are crucial for improving quality of life.
  • Further research is needed to optimize treatment for photosensitivity in albinism.
