The Eye Foundation: Your Trusted Partner for Vitreoretinal Care

Photodynamic therapy (PDT) is a minimally invasive treatment that uses a combination of light and a photosensitizing agent to destroy abnormal cells or blood vessels in the eye. This treatment is particularly effective for treating vision-threatening eye conditions, such as:

  • Age-related macular degeneration (AMD)
  • Central serous chorioretinopathy (CSC)
  • Choroidal neovascularization (CNV)
  • Recurrent pyogenic choroiditis (RPC)
  • Presumed ocular histoplasmosis syndrome (POHS)

How PDT Works

PDT involves a three-step process:

  1. Administration of a photosensitizing agent: The photosensitizing agent, usually verteporfin (Visudyne®), is injected into a vein in the arm. This agent circulates throughout the body and accumulates in abnormal cells or blood vessels in the eye.
  2. Activation of the photosensitizing agent: After a period of time, the eyes are exposed to a specific wavelength of light, typically a non-thermal diode laser. The light activates the photosensitizing agent, causing it to generate reactive oxygen species (ROS).
  3. Destruction of abnormal cells or blood vessels: The ROS generated by the activated photosensitizing agent damages the abnormal cells or blood vessels, leading to their destruction.

Benefits of PDT

PDT offers several benefits over traditional treatments for vision-threatening eye conditions:

  • Minimally invasive: PDT is a non-surgical procedure that does not require incisions or sutures.
  • Targeted therapy: PDT selectively targets abnormal cells or blood vessels, minimizing damage to healthy tissue.
  • Preserves vision: PDT can help stabilize vision and slow the progression of vision loss in many cases.
  • Outpatient procedure: PDT is typically performed in an outpatient setting, allowing patients to return home on the same day.
