Improved accuracy Baseline diagnostic accuracy for non- ophthalmologists with patients presenting with AACG has been demonstrated as 21 per cent (GPs) to 64 per cent (A&E),3 (GPs).4


and 44 per cent for iritis When equally inexperienced observers (GPs


35 per cent, A&E nurse practitioners 23 per cent, opticians 18 per cent) assessed patients presenting with red eye(s) using the Edinburgh Red Eye Diagnostic Algorithm, the diagnostic accuracy for AACG rose to 100 per cent (4/4 cases) and for iritis it rose to 82 per cent (9/11 cases).5 Tese are the first diagnostic eye algorithms to be


subjected to scientific analysis and demonstrate significant improvements in accuracy by inexperienced clinicians in the three most commonly encountered ophthalmic scenarios. Take diplopia as another example: the baseline diagnostic accuracy of non-ophthalmologists including optometrists, hospital doctors and GPs was 24 per

cent, indicating a need for a diagnostic aid. Te overall diagnostic accuracy of the Edinburgh Diplopia Algorithm is 82 per cent, even when used by very inexperienced clinicians. Te diagnostic improvement resulting from the


use of these algorithms should result in more accurate triage of patients referred to the hospital eye service. Tis should help prevent delayed presentations of serious eye conditions and reduce morbidity from delayed treatment.
