As an eyecare professional, providing comprehensive exams is tantamount to patient care. By adding tools, such as ultra-widefield (UWF™) retinal imaging with multiple modalities, the ability to detect pathology, which may be missed with single-image modality and/or conventional narrow-field fundus photography, is a game changer.
UWF retinal imaging is performed by a specially designed scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image covering 200 degrees (or about 82 percent) of the retina, in a single capture. By comparison, conventional 7 standard field (7SF) ETDRS and fundus camera photographs produce a relatively narrow view (75 degrees or less) of the retina. The SLO simultaneously scans the retina using two low-power lasers (red – 633 nm and green – 532 nm) that enable high-resolution, color imaging of retinal substructures. The resulting UWF digital image – optomap or optomap af – UWF retinal imaging utilizing fundus autofluorescence (FAF), is produced.
What is Fundus Autofluorescence?
FAF, is an imaging modality used to provide information on the health and function of the retinal pigment epithelium (RPE). Over time, the retinal photoreceptors naturally age and produce a metabolic waste known as lipofuscin. Lipofuscin is the fatty substance found in the retinal pigment epithelium. Excessive amounts can …![]()
