This study will look at the long-term effects of semaglutide (active medicine) on diabetic eye disease when compared to placebo (dummy medicine). The study will be performed in people with type 2 diabetes. Participants will either get semaglutide or placebo in addition to their diabetes medicines - which treatment the participant gets is decided by chance. Participants will inject the study medicine using a pen-injector. The medicine must be injected in a skin fold in the stomach, thigh or upper arm once a week. The study will last for 5 years.

DRUG

Semaglutide

Participants will get one dose of semaglutide once weekly in addition to their diabetes medicines - which treatment they get is decided by chance. Participants will inject the study medicine using a pre-filled PDS290 pen-injector. The medicine must be injected in a skin fold in the stomach, thigh or upper arm once a week. Participants will start with once-weekly doses of 0.25 mg for 4 weeks, then the dose will be gradually increased to 0.5 mg once weekly for 4 weeks, and finally to 1.0 mg once weekly (maximum dose) up to 260 weeks (5 years).
