The investigators conceived a computerized interactive tool for Emergency Triage, based on a patient's symptoms, medical history and background. Using this tool, the patient (alone or helped by a nurse / supporting person) presenting to an ophthalmologic ER, should be able to detect and prioritize his most urgent symptoms (A,B), in opposition to less urgent (C) or non urgent symptoms (D). To test the validity of this tool, each patient presenting at the Rothschild Foundation ER (Paris, France) with an ophthalmological problem should be included and sorted by the algorithm before the medical consultation. Neither the patient nor the practitioner are aware of the scoring (A,B,C,D) defined by the algorithm. The practitioner should then give his own emergency scoring (A,B,C,D) after patient examination. A total of 1000 patients is expected.
