Inclusion criteria
Inclusion criteria: Control group: A total of 37 patients (37 eyes) with normal eye examination results at the ophthalmology outpatient department of the Nanjing Medical University Affiliated Wuxi Second Hospital were included as controls. The right eye data were collected. The inclusion criteria were as follows: 1. BCVA of >= 0.8, with normal visual field and intraocular pressure; and 2. no history of diabetes. DR group: A total of 37 patients with NPDR who were treated with PRP in the ophthalmology clinic were selected as the DR group. According to the ETDRS Research Group, all patients were included based on the fundus examination and fluorescein fundus angiography (FFA) findings indicating severe NPDR, and thus requiring PRP.
