The purpose of this study is to understand whether genes or certain factors in the environment determine how eyes will respond to Lucentis (ranibizumab) treatment. For example, whether having variants within specific genes means that a patient is likely to get better vision from treatment than another patient with different genes.
Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. The advanced stages of the disease are characterized by the development of geographic atrophy or choroidal neovascularization, both of which result in significant loss of vision. Development of intravitreal anti-VEGF agents such as ranibizumab has significantly improved outcomes for the neovascular for of the disease. However, it is not possible to predict which individuals will respond to the treatment.
The objective of this study is to establish the association between genetic factors and treatment response to intravitreal Lucentis. This will be accomplished by SNP-genotyping participants for AMD-susceptibility and candidate angiogenesis-pathway genes, collecting environmental risk factor variables and evaluating clinical outcomes. The aim of this pharmacogenetics study will be to identify patients at the outset of their treatment that require more intensive therapy.

This is a Phase III, multicenter, randomized, double-masked, dose-comparison study of the efficacy and safety of ranibizumab injection administered intravitreally to patients with CNV seco...
Neovascular age-related macular degeneration (AMD) is the leading cause of severe vision loss in the Western world. Intravitreal ranibizumab has recently become the treatment of choice for...
This study will evaluate the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity compared to ranibizumab monotherapy and the durability of ...
Age-related macular degeneration, a leading cause of blindness, is caused by an abnormal growth of the vessels beneath the retina. Ranibizumab (Lucentis) is a new drug that inhibits the gr...

To evaluate the efficacy and safety between photodynamic therapy (PDT) combined with intravitreal ranibizumab (IVR) and ranibizumab monotherapy in treating wet age-related macular degeneration (AMD).
To assess efficacy of intravitreal ranibizumab in retinal pigment epithelium tears secondary to neovascular age-related macular degeneration.
To compare, in a single urban population, the visual outcomes of ranibizumab monotherapy in "White" (W) and "Non-White" (NW) patients with wet age-related macular degeneration (AMD).
To identify factors associated with ranibizumab responses in patients with exudative age-related macular degeneration (AMD), we performed a genome-wide association study (GWAS) and a replication study...
A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.
A recombinant humanized monoclonal antibody fragment that binds VEGF-A to prevent its binding to VEGFR-1 and VEGFR-2 receptors. This activity reduces vessel permeability and angiogenesis in the treatment of neovascular age-related MACULAR DEGENERATION.
A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)
Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.
A form of RETINAL DEGENERATION in which abnormal CHOROIDAL NEOVASCULARIZATION occurs under the RETINA and MACULA LUTEA, causing bleeding and leaking of fluid. This leads to bulging and or lifting of the macula and the distortion or destruction of central vision.
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
