Inflammation of both the choroid and retina in the eye.
From choroid (Greek khoreoeides 'vein-like') + retina (Latin 'net') + -itis 'inflammation'. Medical term describing concurrent inflammation of two eye layers.
The choroid is the eye's blood vessel network, and the retina is where you actually see—when both get inflamed together, patients can lose vision suddenly, which is an eye emergency.
