title: Simultaneous bilateral fluorescein angiography of the retina and the iris in central retinal vein occlusion.
abstract: Twenty-two patients with a recently developed C.R.V.O. (central retinal vein occlusion) (symptoms: less than four weeks) are discussed. A delay in A.R.C.T. (arm to retina circulation time) in the affected eye was found in two patients with an ischaemic type of C.R.V.O. and in 3 patients with a non-ischaemic type of C.R.V.O. No side difference could be demonstrated in A.I.C.T. (arm to iris circulation time). Leakage of radial iris vessels on fluorescein angiography was found in 6 out of 7 patients with an ischaemic type of C.R.V.O. and in 2 out of 15 patients with a non-ischaemic type of C.R.V.O. Radial iris vessel leakage may be a helpful prognostic sign in C.R.V.O.
