Age Related Macular Degeneration - Wet Form, Optical Coherence Tomographic Image

Most cases of wet macular degeneration are managed by frequent use of Optical Coherence Tomography (OCT). OCT scans show the retina in cross section, and any collections of fluid or growth of tissue in abnormal locations can be detected. In the scan shown here the orange arrow shows fluid underneath the retina and the retinal pigment epithelium (a cell layer just beneath the retina). The yellow arrow shows a cyst of fluid in the retina. These findings lead the retina specialist to recommend injections into the vitreous of drugs that block vascular endothelial growth factor (VEGF). The most common ones are Avastin (bevacizumab - generic name) and Lucentis (ranibizumab - generic name).
