Efficacy and Safety of Intravitreal Bevacizumab in the Treatment of Choroidal Neovascular Membranes Associated to High Myopia

2014-08-27 03:19:43 | BioPortfolio

Summary

The purpose of this study is to determine the efficacy and safety of intravitreal injections of bevacizumab in High Myopia´s choroidal neovascularization versus the standard treatment of Photodynamic therapy.

Description

Bad response in choroidal neovascularization in High myopia to Photodynamic therapy, which is the current approved treatment for that pathology, and the high incidence of this pathology in these patients, together with the great functional impact in their vision has fostered the search for new therapeutic strategies.

Intravitreal bevacizumab has already been tested in small series of patients with choroidal neovascularization associated to high myopia, whether as first treatment option or after the failure of photodynamic therapy with good results. In the published series an improvement of visual acuity is described after 1-2 injections, with a reduction in the macular edema and a good safety profile.

The lack of published trials that describe the efficacy of frequency of treatment in this pathology is the main reason for this trial.

Medical and Biotech [MESH] Definitions

The purified component of HEMATOPORPHYRIN DERIVATIVE, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (HEMATOPORPHYRIN PHOTORADIATION); to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of PHOTODYNAMIC THERAPY in the United States.

Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.

A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.

The administration of substances into the VITREOUS BODY of the eye with a hypodermic syringe.

Historically, tissue transplantation, especially of refrigerated tissue (after Filatov). It was theorized that nonspecific substances, capable of initiating restorative processes, formed in tissues when refrigerated. Cell therapy (after Niehans) refers to implantation of tissue by injection. Originally this involved fresh cells but later frozen or lyophilized cells.
