English

Illustration showing parts of the human eye, including the retina.

Etymology

From Medieval Latin retina, the diminutive form of Latin rete (“net”), probably from the Vulgar Latin phrase (tunica) *retina, literally "net-like tunic", used to describe the blood vessel system at the back of the eye. (Gerard of Cremona may have created this phrase as a translation for Arabic (ṭabaqa) shabakiyya "net-like layer", which translates Ancient Greek ἀμφιβληστροειδής (amphiblēstroeidḗs) (χιτών (khitṓn))).[1]
