Abstract:

Objective Comparison of the sensitivity and specificity of computer automated screening system and ophthalmologist in grading diabetic retinopathy(DR). Design Diagnosis tests. Participants One thousand, one hundred and fifty-five cases of diabetic patients over 40 years old in Beijing Pinggu district were selected. Methods Two-field non-mydriatic fundus photographs center on macular and optic disc were performed. Grading of DR was carried out by two retinal images of one eye. Computer automated screening system carried out by the Software Huiyan from Daheng Prust Medical Technology Co. Ltd. Main Outcome Measure Kappa value, sensitivity, specificity. Results Computer automated screening system and ophthalmologist on the presence of DR with the result of the Kappa values was 0.58. The sensitivity and specificity of the presence of DR on computer automated screening system and ophthalmologist were 87.47% and 74.39% respectively. Computer automated screening system and ophthalmologist on the presence of severe non-proliferative DR with the result of the Kappa values was 0.35. The sensitivity and specificity of the presence of severe non-proliferative DR on computer automated screening system and ophthalmologist were 87.47% and 74.39% respectively. Conclusion These results show that computer automated screening system can efficiently screen retinal images from diabetes populations to reduce the workload of doctors.
