macular

DEFINITION of macular

macular (adj.) refers broadly to anything characterized by or involving small spots, such as macular skin lesions composed of flat, discolored areas without elevation or depression. In eye disease, it describes conditions that affect the retinal macula, for example macular degeneration, macular edema, and macular holes, where pathology in this central retinal zone impairs fine visual tasks like reading and driving. The underlying noun macula denotes a small spot or blotch, either on the skin or in the eye, and in Ophthalmology is shorthand for macula lutea, the yellowish, oval central retinal region with the highest visual acuity.

ETYMOLOGY of macular

latin “macular” is formed from Latin macula meaning “spot, stain” plus the adjectival suffix ‑ar “pertaining to.” The base noun macula has been used in English since about the 15th century for spots or blotches, especially on the skin or eye. In ophthalmic usage, macula lutea (“yellow spot”) appears in the 19th century for the central retinal area opposite the pupil where vision is most distinct. The adjective “macular” is attested by the early 1800s in the sense “spotted,” and by the late 1800s specifically as “pertaining to the macula lutea of the eye.”pmc.ncbi.nlm.nih+2
