Fundus photography and angiography have become an integral part of the management of many retinal conditions, including age-related macular degeneration, diabetic retinopathy, retinal vascular diseases, as well as chorioretinal inflammatory conditions. In this chapter, we will review the clinical utility of these imaging modalities with illustrated examples in a range of common retinal conditions. Recent advances, including widefield photography and angiography, videoangiography and confocal scanning laser ophthalmoscopy-based angiography will be introduced, with illustrative examples of their clinical utility. Color fundus photography (CFP) is a useful tool to document changes in the retina and optic nerve. In the clinic setting, CFP is particularly useful to document baseline findings and facilitate longitudinal comparison. Angiography is a more detailed evaluation which assesses both the intravascular and extravascular compartments of the retina and choroid, usually after an intravenous injection of a fluorescent dye. This guides in the diagnosis, localization, and treatment of various diseases of the choroid and retina. Fluorescein angiography and indocyanine green angiography are the two most commonly used dyes for fundus angiography.
