Purpose:
To report an alternative technique of fundus fluorescein angiography using percutaneous endoscopic gastrostomy (PEG).
Methods:
A case series from a single center.
Results:
Two bed-bound children on tracheostomy received 10% fluorescein sodium via PEG to diagnose their retinal condition. The dye appeared at 5 min after administration and stayed in the retinal circulation past 30 min. Good quality fluorescein angiograms were obtained in all cases. There were no safety issues in these two children.
Conclusions And Importance:
Retinal angiography with fluorescein dye administered via percutaneous endoscopic gastrostomy may represent a suitable alternative to currently used intravenous and oral fluorescein angiography.
