Definition

Noun: * Venae sclerales: A network of small veins (tributaries) that drain blood from the sclera, the white, fibrous outer layer of the eyeball. These veins collect deoxygenated blood and waste products from the scleral tissue and deliver it to the larger anterior ciliary veins.

Examples

• In a medical report: "The examination revealed mild congestion of the venae sclerales, indicating possible inflammation."
• Describing function: "Increased intraocular pressure can affect the flow of blood through the venae sclerales."

Advanced Usage
