Evaluating New Retinal Imaging Techniques

Arch Ophthalmol. 1998;116(4):521-522. doi:10.1001/archopht.116.4.521

OPHTHALMOLOGISTS ARE bombarded with a seemingly bewildering array of new retinal imaging techniques in the 1990s. Novel methods include, to name a few, indocyanine green (ICG) angiography with either digital video cameras1 or scanning laser ophthalmoscopes2; optical coherence tomography3; retinal thickness analyzers4; simultaneous stereophotography5; infrared imaging6; and macular pigment evaluations.7 The article by Freeman et al8 in this issue of the ARCHIVES on simultaneous fluorescein and ICG angiography provides the background for an editorial on this new imaging technique and for considering guidelines for evaluating retinal imaging methods in general. These guidelines may assist investigators who want to evaluate new techniques. They may also assist ophthalmologists in determining if a new technique offers clinically relevant advantages over existing technology and, as such, if it should be considered for incorporation into clinical practice.
