Six cases are presented with macular changes in association with papilloedema; 4 suffered permanent visual loss. The present paper emphasises this previously infrequent finding and discusses the haemodynamic and mechanical factors responsible. The macular changes consisted of haemorrhages situated in front, within, or behind the retina, and occasionally the results of neovascular membrane formation produced secondary visual loss. Changes in the pigment epithelium were seen in 3 cases associated with choroidal folds. Macular stars rarely produce visual loss. Recognition of these changes is important in the assessment of the visual loss in papilloedema.
