Which term describes the normal retina with no visible blood vessels?

• A. Anangiotic
• B. Merangiotic
• C. Paurangiotic
• D. Holangiotic

Answer: (A)

Aangiotic describes the retina having no retinal vessels visible; the retinal tissue is supplied by the choroid instead. In this pattern, you don’t see vessels strung across the retina on exam, which matches the description of a normal retina with no visible blood vessels. If vessels were present across the retina, it would be holangiotic; if they appeared only in a narrow strip, merangiotic; if they were very sparse, paurangiotic. So the correct term is anangiotic because it denotes an avascular retina with no retinal vessels visible.
