Age Related Macular Degeneration (AMD) is the leading cause of blindness in North America. This condition causes a progressive loss of central vision, the part of your vision that allows you to read, drive and see images in sharp detail directly in front of you. The wet form of AMD is characterized by the growth and leakage of small blood vessels into the choroid layer of the eye, or the back of the eye. These leaking blood vessels disrupt the structure and function of the eye, causing loss of vision, particularly the sharp vision created by the macula area of the eye. Currently, the best treatment for wet AMD is a series of injections of an anti-vascular endothelial growth factor (anti-VEGF) drug, ranibizumab (Lucentis). The clinical response to treatment is varied. Approximately 70% of patients see a moderate vision gain (3-line gain on a visual acuity chart), but there are 30% who do not see a similar improvement in vision. There is no way to identify those patients who will respond with significant vision gain versus those who will not experience moderate vision gain. Recent research into AMD has demonstrated that genetic mutations are proving to be key risk factors for patients developing wet AMD, with up to 80% of wet AMD cases explained by inherited genetic variations. Scientists have theorized that there may be a genetic difference between those patients who see significant responses to treatment and those who do not. The investigators will be testing participant's genetic profile using the Macula Risk test and following their progress through the standard treatment for wet AMD over the course of this study. This study aims to demonstrate the association between known genetic variations and patient responses to treatment.
NCT01363570 Age Related Macular Degeneration Drug: Ranibizumab MeSH:Macular Degeneration
Mean change in visual acuity according to individual mutations at the CFH haplotypes/C3 rs2230199 marker/ARMS2 rs10490924 marker and mt A4917G marker, calculated using the Macula Risk findings and visual acuity results as determined using ETDRS visual screening.
Primary Outcomes
Description: Percent probability gains in visual acuity will be assessed by comparing best corrected visual acuity at each follow up appointment by the standardized vision testing, early treatment diabetic retinopathy study (ETDRS) test. The ETDRS visual acuity test was first developed to effectively evaluate visual changes following panretinal photocoagulation in patients with diabetic retinopathy. This method of measuring visual acuity was more accurate than previous methods, and thus has become the global standard, especially for clinical trials where it is essential to have utmost accuracy.
