Embodiment 1

[0019] Please refer to figure 1 , a method for screening diabetic retinopathy, comprising:

[0020] Step A001: Obtaining a dual-view non-mydriatic fundus photographic picture;

[0021] Step A002: Obtain the results of diabetic retinopathy according to the fundus photographs.

[0022] Wherein, in this embodiment, step A001: Obtain a double-view non-mydriatic fundus photographic picture, and the obtained double-view non-mydriatic fundus photographic picture specifically includes: a left eye fundus image centered on the optic disc and macula and a right eye fundus image. Fundus image of the eye. In the existing technology, under normal circumstances, the person to be screened first takes a double-view fundus photo without mydriasis after adapting to the dark room for 5 minutes. The center of the photo is the optic disc and macula, first the right eye and then the left eye. The shooting position, sharpness, readable range and overall quality of the photo should be evaluated, an...

Embodiment 2

[0033] Please refer to Figure 4 , a diabetic retinopathy screening device, comprising: a dual-view non-mydriatic fundus photographic collection device B00, used to collect dual-view non-mydriatic fundus photographic pictures of a person to be screened; a processor B10, used to execute a diabetic Methods of screening for retinopathy. Among them, the dual-view non-mydriatic fundus photography acquisition device B00 can be integrated with the processor B10, or can be used as independent components to form a diabetic retinopathy screening device.

[0034] In this embodiment, a method for screening diabetic retinopathy executed by the processor B10 includes: acquiring double-view non-mydriatic fundus photographic pictures; and acquiring diabetic retinopathy results according to the fundus photographic pictures. Wherein, the dual-view non-mydriatic fundus photographic pictures include left eye fundus images and right eye fundus images centered on the optic disc and macula.

Abstract

The invention discloses a diabetic retinopathy screening method and device and a storage medium. The diabetic retinopathy screening method specifically comprises the steps that a deep convolution neural network model is built in advance through a series of methods including construction of a double-vision mydriasis-free fundus photography picture set, picture preprocessing, model design, model training and verification, and result judgment; when diabetic retinopathy results of a patient need to be screened, double-vision mydriasis-free fundus photography pictures of the to-be-screened patientare obtained, and then the pictures meeting quality requirements are input into the pre-constructed convolution neural network model so that diabetic retinopathy results can be easily and convenientlyobtained. Compared with the prior art, the screening method is simple, convenient to use and good in compliance, and also has the advantages of being high in accuracy, sensitivity and specificity.

Description

technical field [0001] The invention relates to a screening technology for diabetic retinopathy, in particular to a screening method, device and storage medium for diabetic retinopathy. Background technique [0002] Diabetic Retinopathy (DR) is one of the most common microvascular complications of diabetes and the third leading cause of blindness in my country. Early treatment of DR can prevent severe vision loss in 90% of cases. However, due to insufficient medical resources and the complexity of routine fundus examinations, patients' compliance is poor, and up to 50% of diabetic patients do not have regular eye examinations every year. There are many diagnostic methods for DR, including fundoscopy, fundus fluorescein angiography, fundus photography, standard seven-field color stereoscopic photography (seven standard field 35-mm stereoscopic color retinal imaging, 7SF) and so on. Among them, 7SF has strong sensitivity and high diagnosis rate, and is internationally recogn...
