Robotic injection of tPA for treating subretinal hemorrhage

Robotic Subretinal tPA Injection Study

Not applicable Interventional Universitaire Ziekenhuizen KU Leuven · NCT06347107

This study is testing if using a robotic device to help inject a medication under the retina can improve vision for people with bleeding in the eye due to age-related macular degeneration.

What this trial studies

This study aims to evaluate the use of a robotic stabilizer for the subretinal injection of tPA in patients undergoing vitrectomy surgery for submacular hemorrhage. The procedure involves using a 41G subretinal needle and an Inicio micro-injection system, both of which are CE marked, to deliver tPA precisely under the retina. The robotic device will assist the surgeon in positioning the needle accurately, and the injection will be monitored using advanced imaging techniques. The goal is to improve visual outcomes for patients suffering from complications of age-related macular degeneration.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for vitrectomy surgery to treat submacular hemorrhage who can provide informed consent.

Not a fit: Patients under 18 years old or those requiring vitrectomy for indications other than submacular hemorrhage may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the effectiveness of treating subretinal hemorrhage and improve visual acuity in affected patients.

How similar studies have performed: While the use of robotic assistance in surgical procedures is gaining traction, this specific application for subretinal tPA injection is relatively novel and has not been extensively tested in prior studies.
