RESUMO
Digital fundus imaging was used for fluorescein angiography in patients with subretinal neovascularization. After laser treatment, digital red-free photographs were obtained and compared against pretreatment angiogram frames to determine the margins of treatment. This technique allowed instant review of images and confirmation of complete laser treatment of the lesions. Of 15 eyes treated and followed for at least one year, there were two eyes with early recurrences (13%). A total of five eyes had recurrences during the follow-up period (33%). Digital imaging is a useful tool for treating subretinal neovascularization.

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.
