Abstract
PURPOSE: To describe the intraoperative use of the Heidelberg Spectralis for ultra-widefield fundus fluorescein angiography in infants. DESIGN: Retrospective observational case series. METHODS: A modified Heidelberg Spectralis was used to perform ultra-widefield fundus fluorescein angiography in infants undergoing an examination under general anesthesia for a range of retinal vasculopathies. Peripheral angiographic findings, angiographic image acquisition time, and any complications were reviewed. RESULTS: A total of 22 eyes of 11 infants underwent intraoperative ultra-widefield fundus fluorescein angiography using the modified Heidelberg Spectralis. Ultra-widefield fundus fluorescein angiography was successfully performed in all infants and permitted capture of the posterior pole as well as the peripheral retina in a single shot centered on the macula. Peripheral retinal pathologies captured include neovascularization, capillary nonperfusion, and skip areas from previous laser treatment. Capturing of angiographic images took a mean time of 7.09 minutes. Image artifact from condensation of the ultra-widefield lens was noted during imaging of 1 infant. CONCLUSIONS: The modified Heidelberg Spectralis is an effective and reliable imaging tool for performing ultra-widefield fundus fluorescein angiography in infants. It is capable of capturing wide-angle images of high quality. The technique has advantages as an alternative to RetCam fluorescein angiography in infants undergoing an examination under general anesthesia.
