LIPEMIA retinalis is that condition found ophthalmoscopically in a patient with hyperlipemia in whom the blood lipids have become sufficiently increased to alter the appearance of the retinal blood column, the arteries and veins appearing as broad creamcolored ribbons against a milky background. Hyperlipemia occurs as the result of an abnormal increase in the neutral fats, the serum developing a milky appearance when the neutral fat content reaches about 500 mg. per 100 cc. Lipemia retinalis, however, does not appear until the neutral fat content is much higher.
According to Thannhauser,1 the amount of lipid substance in the serum is dependent upon the following factors: (1) the absorption of fat from the intestine; (2) the migration of fat from fat depots to the organs of fat disintegration; (3) the deposition of fat in subcutaneous and other fat-storing tissue; (4) the speed of fat disintegration in the organs, that is,
