The document lists various eye conditions and diseases. It then provides questions to ask a 32-year-old Turkish patient presenting with recurrent red eye to determine the cause. Key questions relate to duration and severity of symptoms, presence of discharge or vision changes, relieving/aggravating factors, and past medical and ocular history to determine if the red eye is due to conjunctivitis, iritis, trauma, or a more serious condition like glaucoma or corneal ulcer. Exam findings like photophobia or a visible foreign body could also provide clues to the diagnosis.
