Application of Non-mydriatic Digital Fundus Camera in Remote Screen of Diabetic Retinopathy for Community Residents / 中山大学学报(医学科学版)

ABSTRACT

[Objective]To evaluate the practicality of non-mydriatic digital fundus camera in the remote screen of diabetic retinopathy for community residents.[Methods]Ninety-two patients(184 eyes)with type 2 diabetes mellitus have been taken 1-field and 5-field non-mydriatic fundus photography and examination in mydriatic fundus by pre-placed-mirror ophthalmoscopy by a ophthalmologist,the results were sent to the hospital with a computer programs. A specialist evaluates the consistency of detectable rate of diabetic retinophathy(DR)among the 3 methods.The time of tak-ing 1-field and 5-field non-mydriatic fundus photography is compared.[Results]All the three methods show good consis-tency in detectable rate of DR compare with each other,the κ value is 0.89 for 1-field non-mydriatic fundus photography and examination in mydriatic fundus by preplaced-mirror ophthalmoscopy,0.95 for 1-field and 5-field non-mydriatic fundus photography and 0.95 for 5-field non-mydriatic fundus photography and examination in mydriatic fundus by pre-placed-mirror ophthalmoscopy,respectively. The 1-field non-mydriatic fundus photography spent less time compares with 5-field non-mydriatic fundus photography(55.4±5.8 vs 405.9±68.5 s,P<0.01).[Conclusion]The remote screen for diabetic retinopathy in community based on non-mydriatic digital fundus camera is worth promoting,we suggest 1-field non-mydriatic fundus photography as a screen method.
