Corneal arcus is frequently associated with early coronary artery disease.
An "arcus" feature is a roll or shelf cloud that forms along the leading edge of a squall line or thunderstorm outflow.
This arch of the azygos vein ("arcus venae azygos") is an important anatomic landmark.
A xanthelasma or corneal arcus may also be seen.
Placing the balloon too distal from the arcus aortae may induce occlusion of the renal artery and subsequent renal failure.
Unilateral arcus is a sign of decreased blood flow to the unaffected eye, due to carotid artery disease or ocular hypotony.
Arcus was designed to accommodate electric, gas-self-launch, gas-sustainer, or no motor.
Some arcus clouds form as a consequence of interactions with specific geographical features.
Compare the limbus sign (calcification) with arcus senilis (lipid).
