The fibro vascular membrane eventually contracts, causing peripheral anterior synechaie formation and secondary angle-closure glaucoma. This site needs JavaScript to work properly.

The etiology of the fibro vascular membrane is ischemia from a variety of causes.

It is characterised by anterior segment neovascularisation leading to an increase in intraocular pressure (IOP) and glaucomatous optic neuropathy. This volume contains the papers presented at the International Symposium on Fluorescein Angiography held in Ghent, from 28 march to 1 april 1976, under the presidency of Prof. J. Fran90is.
