Venae Conjunctivales, also known as the conjunctival veins, are the tiny blood vessels that are present in the mucous membrane of the eyes. These veins can become dilated, causing redness and irritation in the eyes. There are several synonyms for these veins, including scleral vessels, bulbar vessels, episcleral vessels, and subconjunctival vessels. These terms are often used interchangeably and are medically relevant for diagnosing eye diseases and treating infections. Understanding the synonyms for conjunctival veins is important for ophthalmologists and optometrists to provide the best possible care to their patients and maintain the eye's health.
