Watching a short video before anti-VEGF eye injections

Impact of Procedural Video Viewing on Patients Undergoing Intravitreal Anti-VEGF Injections

Not applicable Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT07002372

This trial will test whether watching a brief procedural video before a first anti-VEGF intravitreal injection helps people with retinal diseases feel less anxious and have fewer or smaller subconjunctival hemorrhages.

What this trial studies

Adults receiving their first intravitreal anti-VEGF injection for retinal disease are randomly assigned to watch an educational video explaining the injection procedure or to receive standard care without the video. Anxiety is measured with the State-Trait Anxiety Inventory-State (STAI-S) before and after the injection, and clinicians record the presence and area of subconjunctival hemorrhage after the procedure. Patient satisfaction and immediate procedural experience are also collected. The trial is conducted at the Second Affiliated Hospital, School of Medicine, Zhejiang University in Hangzhou, China.

Who should consider this trial

Good fit: Ideal candidates are mentally competent adults receiving their first intravitreal anti-VEGF injection for retinal disease who can communicate without barriers and are willing to sign informed consent.

Not a fit: Patients with prior eye surgery, a best-corrected visual acuity in the better eye worse than 0.3, or a target eye complicated by neovascular glaucoma are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the video could reduce procedure-related anxiety and decrease the frequency or size of subconjunctival hemorrhages, improving patient comfort and satisfaction.

How similar studies have performed: Video-based and other preprocedure education have reduced anxiety and increased satisfaction in other medical and ophthalmic settings, but direct evidence specific to intravitreal injections is limited.
