The Retina01:32

The Retina

74.6K
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

773
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

8.8K
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,...

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

9.5K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

24.0K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Absorption of Nutrients01:19

Absorption of Nutrients

2.8K
Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

Summary

Nutrition impacts retinal diseases, but evidence is limited for most conditions. Antioxidant supplements show proven benefits only for Age-Related Eye Disease Study (AREDS) participants with intermediate age-related macular degeneration (AMD).

Area of Science:

  • Ophthalmology
  • Nutritional Science
  • Retinal Disease Research

Background:

  • Nutrition's role in retinal disease is increasingly discussed, fueled by supplement marketing.
  • Scientific evidence for many nutritional impacts on retinal diseases remains limited.
  • Established nutritional interventions exist for rare conditions like retinitis pigmentosa.

Purpose of the Study:

  • To review the current evidence on nutrition's impact on retinal disease manifestation and progression.
  • To evaluate the efficacy of antioxidant supplementation and dietary changes for various retinal conditions.
  • To identify areas requiring further research in nutritional ophthalmology.

Main Methods:

  • Review of prospective clinical trials and experimental studies.

  • Analysis of data from the Age-Related Eye Disease Study (AREDS).
  • Examination of associations between diet, cholesterol, and retinal disease progression.

    • Main Results:

    • High-dose antioxidant and zinc supplementation (AREDS) benefits intermediate age-related macular degeneration (AMD) progression in non-smokers.
    • The efficacy of other antioxidants (lutein, zeaxanthin) and preventive supplementation is unclear.
    • High-fat diets and cholesterol levels are linked to retinal disease progression; smoking exacerbates oxidative stress.

    Conclusions:

    • A balanced, low-fat diet and standard vitamin intake are advisable for general eye health.
    • AREDS supplementation is recommended only for specific AMD patients (non-smokers, intermediate stage).
    • Further clinical studies are needed to explore nutritional strategies for common retinal diseases.
