different between retina vs emmetropia

English

Etymology

From Medieval Latin r?t?na, an adjectival form of Latin r?te (“net”), from the Latin phrase (tunica) r?t?na, literally "net-like tunic", used to describe the blood vessel system at the back of the eye. The phrase is attested in the 12th century in Guillelmus the abbot and Gerard of Cremona—the latter may have created this phrase as a translation for Arabic ??????? ??????????? (?abaqa šabakiyya) "net-like layer", which translates Ancient Greek ???????????????? ????? (amphibl?stroeid?s khit?n).

Latin

Etymology 1

Generally explained as a deverbal derivation from retine? (“I hold back, retain, restrain”), with feminine -a.

Classical Latin had the term retin?culum n, which occurred almost exclusively in the plural (retin?cula (“reins”)). This plural may have been reinterpreted as a diminutive feminine singular, then undergoing back-formation to form a non-diminutive retina.

• (Ecclesiastical) IPA^(key): /?re.ti.na/, [?r??t?in?]
