Increased cup to disc ratio eye
WebFeb 7, 2024 · The vertical size of the cup can be estimated in relation to the optic disc as a whole, known as the “cup-to-disc ratio”. A cup-to-disc ratio of 0.3 (i.e. the cup occupies one-third of the height of the optic disc) is generally considered normal. An increased cup-to-disc ratio suggests a reduced volume of healthy neuro-retinal tissue, which ... WebA small C:D ratio may lower the threshold for developing optic disc edema from ischemia, increased intracranial pressure, or other mechanisms. Additional studies are needed to confirm these findings. Cup-to-disc ratio in patients with idiopathic intracranial hypertension is smaller than that in normal subjects
