No: Conjunctivitis is defined as inflammation of the conjunctiva. One of the principle markers of inflammation is redness caused by dilation of the blood vessels. Therefore, all forms of conjunctivitis have varying degrees of associated redness. However, not all redness is caused by conjunctivitis. For example, a broken blood vessel can cause redness but is not caused by inflammation.
