In which condition might you observe inflammation indicated by the suffix "itis"?

The suffix "itis" is commonly used in medical terminology to denote inflammation. In the context of the choices provided, "conjunctivitis" is the condition characterized by inflammation, specifically of the conjunctiva, which is the membrane covering the white part of the eyes and the inner eyelids. Conjunctivitis can present with symptoms such as redness, itching, and discharge, clearly indicating an inflammatory process.

The other conditions mentioned do not primarily involve inflammation as a defining characteristic. Cataracts refer to the clouding of the eye's lens, myopia (nearsightedness) is a refractive error without an inflammatory component, and retinal detachment is a serious condition involving the separation of the retina, which may not involve inflammation in the same way that conjunctivitis does. Hence, conjunctivitis is the most accurate choice concerning inflammation as indicated by the suffix "itis."
