Morphology
macula + lutea
The compound is compositionally a noun + adjective meaning literally 'yellow spot' (macula = central spot; lutea = yellow). However, 'lutea' is a Latin medical adjective and is not a common English word or particle, so an average B1 learner—even if they know 'macula'—is unlikely to know or recognize 'lutea' or the Latin word order; the meaning is partly recoverable but requires specialist/Latin knowledge.
Etymology
The term macula lutea comes from Latin words macula ('spot') and lutea ('yellow'), so it literally means a 'little yellow spot' near the center of the back of the eye. That simple picture, a small yellow patch full of light-sensing cells, helps explain why the name refers to the area that gives 'sharp, detailed central vision'.
