Endoscopic fluorescein angiography
1Manhattan eye, ear and Throat Hospital, New York, NY, USA.
Background And Objective:
To assess features of various retinal and choroidal disorders by endoscopic fluorescein angiograms (EFAs) obtained intraoperatively.
Patients And 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.
Conclusion:
EFA defines pathologic retinal/choroidal areas intraoperatively, which may permit more selective surgical management during vitrectomy.
