Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: Patients with diabetic retinopathy at various levels have their last available ultrawide field fluorescein angiography done.

Exclusion criteria

Exclusion criteria: 1. Any media opacities that could severely affect the evaluation of retinal non-perfusion on Optos fundus fluorescein angiography. 2. Any condition other than diabetic retinopathy that, from the investigator's point of view, could severely affect the vision.

Design outcomes

Primary

MeasureTime frame
Patients' perceived disease burden, including mobility, self-care, usual activities, pain/discomfort and anxiety/depression, will be measured using the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ 25) and EuroQol Five-Dimensional Questionnaire Five Levels Vision Bolt-on (EQ-5D-5L Bolt-on) at the time around the patient's latest fluorescein angiography.

Secondary

MeasureTime frame
Testing different parameters' ability to reflect a patient's quality of life by comparing each parameter's receiver operating curve (ROC) to diagnose a low NEI-VFQ 25 score cross-sectionally.
