This study plans to compare the accuracy of artificial intelligence (AI)-assisted fundus images with other ophthalmic devices such as optical coherence tomography (OCT) and fundus fluorescence angiography (FFA) in the diagnosis of diabetic retinopathy and diabetic macular edema.

This study plans to compare the accuracy of artificial intelligence (AI)-assisted fundus images with other ophthalmic devices such as optical coherence tomography (OCT) and fundus fluorescence angiography (FFA) in the diagnosis of diabetic retinopathy and diabetic macular edema.

This study was conducted as a prospective study. Participants meeting eligibility criteria will be recruited from sites staffed by trained photographers. After assessing eligibility and obtaining informed consent, fundus photographs will be taken using a non-dilated fundus camera. And optical coherence tomography or fundus fluorescence angiography will be performed.

Inclusion Criteria:

1. Diagnostic for diabetes: Type 1 diabetes of a lest 5 years of evolution; or Type 2 diabetes;
2. Obtaining informed consent;
3. Patient age 18 or above.

Exclusion Criteria:

1. Patients under 18 years of age;
2. Failure to Obtain informed consent;
3. Presence of other retinal diseases;
4. A patient who has already undergone the treatment.

It is planned to include 1,000 participants in the study, all of whom will undergo fundus photography, 500 additional patients will undergo fundus fluorescence angiography, and 500 additional patients will undergo optical coherence tomography.

All participants met inclusion and exclusion criteria.
