Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Current treatment options for this condition have included include laser therapy, photodynamic therapy (PDT), and intraocular injections (different types of anti-vascular endothelial growth factors) alone or in combination. While current treatments were demonstrated to slow the progression of vision loss, neither therapy was shown to significantly improve visual acuity.
Given their different modes of action, it is believed that combination therapy of Ranibizumab with PDT may lead to better visual outcomes and may result in an improved effect in treating AMD and therefore may help decrease the need for monthly Ranibizumab injections. After the first injection, regardless of which group the patient has been assigned to, they will receive Ranibizumab injections at 4 week intervals if clinically indicated. The purpose of the this study is to evaluate the visual outcomes of intraocular Ranibizumab injections in combination with photodynamic therapy with verteporfin for the treatment of neovascular AMD.
