Photodynamic therapy offers a new treatment for wet age-related macular degeneration, targeting abnormal blood vessels. Nurses face new challenges in administering this therapy and educating patients on precautions and side effects.

Area of Science:

  • Ophthalmology
  • Medical Therapeutics

Background:

  • Neovascular (wet) age-related macular degeneration (AMD) is a primary cause of vision loss in individuals over 50.
  • Choroidal neovascularization, abnormal vessel growth under the retina, causes severe visual impairment in wet AMD patients.

Purpose of the Study:

  • To introduce photodynamic therapy (PDT) as a novel treatment for wet AMD.
  • To highlight the nursing implications and challenges associated with PDT in an ambulatory laser setting.

Main Methods:

  • PDT involves intravenous injection of a photosensitizing drug (e.g., verteporfin).
  • Nonthermal laser light is applied to activate the drug, selectively destroying choroidal neovascularization.
  • Focus on the nursing scope: medication preparation, administration, and patient education.

Main Results:

  • PDT effectively destroys choroidal neovascularization.
  • Normal surrounding tissue remains undamaged.
  • New nursing responsibilities arise in managing PDT.

Conclusions:

  • Photodynamic therapy is a promising treatment for wet AMD.
  • Nurses require specific training for PDT medication management and patient support.
  • Addressing nursing challenges is crucial for successful PDT implementation.
