Retinitis Pigmentosa Fact #21
Hey! Did you know that RP is a misnomer? A misnomer is something that is named inappropriately. There was, if you will, an error when naming this disease. Why is RP a misnomer? Well, because the word "retinitis" emplies that there is swelling or an inflamatory response, which has not been shown to be a predominent feature in this disease. (source) Cool huh?
