Recent findings Fluorescence lifetime imaging ophthalmoscopy is a technology that will reveal biochemical and metabolic changes of the retina at the cellular level. Optical coherence tomography is evolving exponentially toward higher resolution, faster speed, increased portability and more cost effective. Adaptive optics scanning laser ophthalmoscopy fluorescein angiography will provide unprecedented detail of the retinal vasculature down to the level of capillaries, enabling earlier and more sensitive detection of retinal vascular diseases. Summary Continued developments in retinal imaging focus on improved resolution, faster speed and noninvasiveness, while providing new information on the structure–function relationship of the retina inclusive of metabolic activity at the cellular level.
