Photodynamic Therapy (PDT)

Photodynamic Therapy (PDT)

Photodynamic Therapy (PDT) is a treatment method that utilizes light interaction with a special photosensitive substance, particularly effective in managing diseases related to the eyes.

 

This treatment is commonly used for the following eye conditions:

1. Age-Related Macular Degeneration (AMD): AMD is a condition characterized by damage to the macula, leading to vision loss as part of the aging process. Photodynamic Therapy can assist in controlling the progression of this condition.

2. Retinal Issues: Photodynamic Therapy may be applied to treat certain retinal problems. Conditions such as retinal vascular diseases, retinal tears, or abnormal blood vessel growth fall among the cases where Photodynamic Therapy can be considered.

 

How Is It Applied?

  1. Application of Photosensitive Substance: The patient is injected with a special photosensitive substance through the bloodstream.

  2. Light Application: The injected substance is activated by exposing it to light of a specific wavelength, often accomplished with a focused laser light directed into the eye.

  3. Targeted Cell Damage: The activated photosensitive substance affects the targeted blood vessels, particularly reducing abnormal blood vessel growth and controlling inflammatory processes.

 

Advantages of Photodynamic Therapy:

  1. Targeted Treatment: PDT focuses on affected areas, minimizing damage to other healthy tissues.

  2. Low Side Effect Profile: Generally, PDT has a lower side effect profile compared to other treatment methods.

  3. Repeatability: In certain cases, Photodynamic Therapy can be repeated for long-term management.
