(1) Underlying Diabetic Retinopathy (DR) is the primary cause of poor vision in young adults. There are automatic image reading systems that can aid screening for DR. (2) Methods: Using our automatic reading system we have counted the number of microaneurysms and hemorrhages in the four quadrants of the ETDRS grid and evaluated the differences between them according to the type of DR. The study was carried out using data from two different databases, MESSIDOR and MIRADATASET. (3) Results: The majority of microaneurysms and hemorrhages are found in the temporal and inferior quadrants of the ETDRS grid. Differences are significant with respect to the other two quadrants at < 0.001. Differences between the type of DR show that severe-DR has a greater number of microaneurysms and hemorrhages in the temporal and inferior quadrant, being significant at < 0.001. (4) Conclusions: The count of microaneurysms and hemorrhages is higher in the temporal and inferior quadrants in all types of DR, and those differences are more important in the case of severe-DR.
(1) 潜在糖尿病视网膜病变（DR）是年轻人视力低下的主要原因。存在可辅助DR筛查的自动图像读取系统。(2) 方法：使用我们的自动读取系统，我们对ETDRS网格四个象限中的微动脉瘤和出血数量进行了计数，并根据DR类型评估了它们之间的差异。该研究使用来自两个不同数据库MESSIDOR和MIRADATASET的数据进行。(3) 结果：大多数微动脉瘤和出血位于ETDRS网格的颞侧和下方象限。与其他两个象限相比，差异极显著（<0.001）。DR类型之间的差异表明，重度DR在颞侧和下方象限有更多的微动脉瘤和出血，差异极显著（<0.001）。(4) 结论：在所有类型的DR中，颞侧和下方象限的微动脉瘤和出血计数更高，并且在重度DR的情况下这些差异更为显著。
