The value of fluorescein fundus angiography in evaluating optic disc oedema.
43 patients with blurred disc margins were studied by means of fluorescein fundus angiography. The differentiation between very early disc oedema and a normal disc was possible, due to an increased capillary network, some microaneurysms and the late fluorescence located in a special circular manner at disc margin. It was not possible to differentiate between optic neuritis and papilloedema, although minor differences may exist. Ischaemic optic neuropathy is a type of optic disc oedema which clearly differs from other causes of oedema when studied by fluorescein fundus angiography. The method is especially suitable in differentiating pseudopapilloedema from genuine oedema of the optic disc.
