Insights

Age-related macular degeneration (AMD) signs were reliably identified in selectively bred rhesus monkeys. This animal model shows disease progression, ultrastructure, and functional losses parallel to human AMD.

Area of Science:

  • Ophthalmology
  • Primatology
  • Genetics

Background:

  • Age-related macular degeneration (AMD) is a leading cause of vision loss in humans.
  • Establishing reliable animal models is crucial for understanding AMD pathogenesis and developing treatments.

Purpose of the Study:

  • To determine if selectively bred rhesus monkeys (Macaca mulatta) exhibit signs of age-related macular degeneration (AMD).
  • To assess the utility of this primate model for studying AMD progression and functional loss.

Main Methods:

  • Selective breeding of rhesus monkeys over 14 generations in a closed colony.
  • Observation and documentation of age-related macular degeneration (AMD) signs.
  • Evaluation of disease progression, ultrastructure, and functional losses.

Main Results:

  • Reliable identification of age-related macular degeneration (AMD) signs in the studied monkey colony.
  • Observed progression, ultrastructural changes, and functional losses parallel those seen in human AMD patients.

Conclusions:

  • Selectively bred rhesus monkeys serve as a reliable model for age-related macular degeneration (AMD).
  • This model can facilitate research into AMD progression and the efficacy of potential therapies.

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
