For the past few years,artificial intelligence (AI) technology has developed rapidly and has become frontier and hot topics in medical research.While the deep learning algorithm based on artificial neural networks is one of the most representative tool in this field.The advancement of ophthalmology is inseparable from a variety of imaging methods,and the pronounced convenience and high efficiency endow AI technology with promising applications in screening,diagnosis and follow-up of ophthalmic diseases.At present,related research on ophthalmologic AI technology has been carried out in terms of multiple diseases and multimodality.Many valuable results have been reported aiming at several common diseases of ophthalmology.It should be emphasized that ophthalmic AI products are still faced with some problems towards practical application.The regulatory mechanism and evaluation criteria have not yet integrated as a standardized system.There are still a number of aspects to be optimized before large-scale distribution in clinical utility.Briefly,the innovation of ophthalmologic AI technology is attributed to multidisciplinary cooperation,which is of great significance to China's public health undertakings,and will be bound to benefit patients in future clinical practice.

Objective To investigate the compliance of follow-up and the associated factors of diabetic retinopathy screening among diabetes patients in Muping District,Yantai City.Methods 438 diabetes patients who received free diabetic retinopathy (DR) screening in Traditional Chinese Medicine Hospital of Muping District of Yantai City from April 2012 to June 2013 were enrolled in the cross-sectional study.The re-examination rate at five years later,as well as the possible associated factors,including age,gender,height,weight,education level,occupation,past medical history,smoking and drinking habits,diabetes process,diabetes medication history,severity of DR,glycosylated hemoglobin (HbA1 c),renal functionand blood lipid were analyzed and evaluated.Results Among 438 patients,159 returned for check up five years later,with a follow-up rate of 36.3％.Further analysis revealed that follow-up rate was related to occupation types (P =0.003) and HbAlc level (P =0.006).Other factors did not show statistical significance (P ＞ 0.05).Conclusions The compliance of DR screening visits is related to occupational type and blood glucose control.It is suggested that in the screening of DR in China,we should pay attention to the propaganda and education of diabetic patients to control blood glucose,and focus on some occupational diabetes people,such as housework workers and farmers.
