ICG useful for retinal imaging in eyes with corneal opacities

BETHESDA, Md. — Indocyanine green angiography can be a useful tool in cases with corneal opacities in which imaging of the retina is not possible with conventional methods, according to researchers here. Clinicians at the National Institutes of Health described a case study in which ICG angiography allowed a view of the retina when other methods could not.
A 31-year-old patient with nephropathic cystinosis and complaints of decreased vision in one eye underwent a complete ophthalmologic evaluation. Using conventional imaging methods including direct and indirect ophthalmoscopy and fluorescein angiography, the view of the retina was obscured by densely packed corneal cystine crystals. Using ICG videoangiography, clear imaging of the retina was obtained using near-infrared illumination.
The case study is published in the July issue of American Journal of Ophthalmology.
