Endoscopic fluorescein angiography.
OBJECTIVE
To assess features of various retinal and choroidal disorders by endoscopic fluorescein angiograms (EFAs) obtained intraoperatively.


METHODS
One hundred patients undergoing vitrectomy were studied intraoperatively by injecting 5 ml of 10% fluorescein intravenously. Up to 110 degrees field of view high-resolution angiograms were obtained endoscopically. Characteristics of diabetic retinopathy, retinal vein occlusion, retinal vasculitis, exudative macular degeneration, and neovascular glaucoma were recorded.


RESULTS
Capillary nonperfusion, retinal vascular occlusion or incompetence, and neovascularization of the disc, retina, subretinal space, and posterior iris could be delineated.


CONCLUSIONS
EFA defines pathologic retinal/choroidal areas intraoperatively, which may permit more selective surgical management during vitrectomy.
