20100247626 | PEGYLATED COMPOUNDS FOR AGE-RELATED MACULAR DEGENERATION - A special photosensitizer formulation and Photodynamic Therapy method for treating choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD) is provided. CNV is a major cause for vision loss in elderly patients. A special drug delivery formulation is used to encapsulate the hydrophobic photosensitizer, preferably a pegylated liposome.

In one preferred embodiment, a pegylated photoactive agent remains confined in the intravascular compartment of neovasculature for a longer duration. Thus efficient elimination of neovascular proliferation and minimal damage to extravascular tissue and normal vessels is ensured. In this method, a hydrophobic photosensitizer, that is able to photochemically destroy neovessels, is injected into the patient. CNV irradiation with a non-thermal laser follows after a predefined time interval. The excited photosensitizer photocoagulates newly formed blood vessels thereby improving the vision and preventing further loss of vision. | 09-30-2010 |
20110034854 | PDT ASSISTED VISION CORRECTION AND SCAR PREVENTION - A method and formulation are disclosed for improving the results of corneal refractive surgery, and generally reducing post-operative scarring and scarring arising from other traumas. In the vision examples, after completion of a procedure, including Photorefractive Keratotomy (PRK) or Laser-In-Situ Keratomileusis (LASIK), a photosensitizer or photosensitizer precursor is applied to the treatment site. After allowing sufficient time for the photosensitizers to accumulate among proliferating cells that occur as a result of ablation, radiation appropriate to activate the photosensitizers is administered to the treatment site. The photosensitizer is thus activated to destroy only those proliferating cells. In this way, proliferating tissue is eliminated and the cornea maintains the shape created during the surgery. As a result, instances of regression and the need for follow-up treatments, is minimized. This method is also useful for preventing post-surgical scarring that can lead to vision problems such as corneal haze. Likewise the method and formulations, presented here, are suitable for reducing post-operative scarring, and trauma cased scarring in general. For such scars, a photosensitizer or photosensitizer precursor is topically applied to the treatment site. After allowing sufficient time for the photosensitizers to attach to proliferating cells, radiation appropriate to activate the photosensitizers is administered to the treatment site. The photosensitizer is activated to destroy only those proliferating cells. | 02-10-2011 |
