Study Summary

Study Objective The goal of this clinical trial is to evaluate whether viewing a procedural video can improve the patient experience and reduce the incidence and severity of subconjunctival hemorrhage in individuals undergoing intravitreal anti-VEGF injections.

Key Research Questions

  1. Can viewing the procedural video prior to treatment reduce the rate and/or area of subconjunctival hemorrhage?

  2. Can the video improve the patient experience, specifically by reducing anxiety levels and increasing satisfaction with the treatment process?

Study Design Participants will be randomly assigned to either an intervention group, who will watch an educational video explaining the injection procedure, or a control group, who will not view the video.

All participants will complete the State-Trait Anxiety Inventory-State (STAI-S) questionnaire both before and after treatment to assess changes in anxiety levels.
