Advances in optics and digital photography have allowed us to photograph portions of the retina that we previously were not able to capture with ease or reliability. This has allowed us to monitor and recognize lesions in the peripheral retina.
In addition to fundus photography, our wide-field viewing systems have extended to other diagnostic tests such as fluorescein angiography, autofluorescence and indocyanine green angiography. By casting a wider view, our diagnostic capability now allows us to detect and monitor disease in the far reaches of the retina, which was previously not possible.
