Genetic Assessment of Early to Late Macular Degeneration Study

Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. To date, two major polymorphisms on the HTRA1 and CFH genes have been associated with AMD. Progression and vision loss need to be followed and treated promptly in order to preserve vision. This study will provide more information on the genetics of disease progression and may lead to future guidelines for patient follow-up and treatment. This study consists of a blood draw and observation of eye conditions. Consented, enrolled patients will come in every four months as per standard of care. At each visit, visual acuity measurement, slit lamp exam, indirect ophthalmoscopy, fundus photos, and spectral domain optical coherence tomography will be performed. Every 8 months, or per standard of care, fluoroscein angiography will be performed. DNA extraction and genotyping will be performed, and correlations between HTRA1 and CFH genotypes and the progression to bilateral advanced AMD will be analyzed.
