Clinical Trial Summary

The purpose of this study is to determine the effectiveness of antiangiogenic therapy to choroidal neovascularization secondary to pathologic myopia.

Description:

The purpose of this study is to determine the effectiveness of antiangiogenic therapy to choroidal neovascularization secondary to pathologic myopia.

This study is planned as a follow-up. Patients with myopia included in it will receive antiangiogenic therapy in accordance with the approved indications for use indicated in the instructions for the use of drugs in Ukraine.

The treatment proposed in this study is based on the world experience and scientific developments of the Filatov Institute of Eye Diseases and Tissue Therapy of the NAMS of Ukraine ". Therefore, it is expected that the benefit / risk ratio in relation to the participation in this study should not be different from that described in the scientific literature and the benefits outweigh the risk. It is known that the absence of treatment in these diseases leads to an irreparable loss of central vision.

Patients with a pathologic myopia with CNV (native) will be treated with antiangiogenic drugs according to the regimen pro re nata.
