Subtraction angiography of the orbit
Modern Problems in Ophthalmology
|January 1, 1975
Abstract:
The principles and techniques of subtraction angiography are described. The superimposed confusing shadows are eliminated so that the small opacified arteries and veins as well as the choroidal plexus are clearly seen. The method is useful in the diagnosis of intraocular tumours and in localizing deeply seated intraocular foreign bodies.
