Abstract
A photodynamic therapy technique for preventing damage to the fovea of the eye or another body portion of a patient is disclosed herein. In one embodiment, a treatment laser is applied to a body portion of a patient using a painting technique, the treatment laser being configured to provide paint brush-type photodynamic therapy (PPDT) using the painting technique to the body portion of the patient by emitting light of a predetermined wavelength that is absorbed by tissue of the body portion of the patient to which a photosensitizer has been applied, the body portion of the patient being afflicted by a medical condition. The application of the treatment laser to the body portion of a patient using the painting technique treats the medical condition, reduces the symptoms associated with the medical condition, and/or alleviates the medical condition.
