This method of examining the retinal vascular system would appear to open new possibilities in the investigation of various fundal states including the relationship between the colour of the optic disc and its capillary content, the state of the capillary bed especially at the edge of the disc in glaucoma, and its relationship to visual field defects, new-vessel formation in the retina and vitreous, the extent of the capillary free zone at the macula in various conditions, etc. It also affords an opportunity of investigating the degree of collateral circulation existing in the optic nerve head and choroid. Summary 1. A method is described of injecting the retinal vascular system in the freshly enucleated eye. 2. Indication is given of the possible usefulness of this new technique
