Digital fundus imaging: a comparison with photographic techniques.Ann Ophthalmol. 1991 Feb; 23(2):46-53.AO
Fluorescein angiographic images from digital and photographic systems were obtained simultaneously from consecutive patients and examined in a side-by-side manner for evaluation of graininess, contrast, focus, and overall image quality. Digital fundus images showed superior contrast and overall image quality compared with photographic images obtained in this manner. These images were rated as somewhat grainier than photographic images. Patients had fewer complications undergoing digital fluorescein angiography versus photographic fluorescein angiography. Digital fundus imaging is a legitimate alternative to photographic imaging and offers the potential advantage of fewer complications compared with photographic techniques.
