A Deep Learning-Driven Autonomous System for Retinal Vein Cannulation: Validation Using a Chicken Embryo Model
Yi Wang, Peiyao Zhang, Mojtaba Esfandiari +2
Retinal vein cannulation (RVC) is a minimally invasive microsurgical procedure for treating retinal vein occlusion (RVO), a leading cause of vision impairment. However, the small s…
Deep Learning-Enhanced Robotic Subretinal Injection with Real-Time Retinal Motion Compensation
Tianle Wu, Mojtaba Esfandiari, Peiyao Zhang +3
Subretinal injection is a critical procedure for delivering therapeutic agents to treat retinal diseases such as age-related macular degeneration (AMD). However, retinal motion cau…
Towards Motion Compensation in Autonomous Robotic Subretinal Injections
Demir Arikan, Peiyao Zhang, Michael Sommersperger +7
Exudative (wet) age-related macular degeneration (AMD) is a leading cause of vision loss in older adults, typically treated with intravitreal injections. Emerging therapies, such a…
Real-time Deformation-aware Control for Autonomous Robotic Subretinal Injection under iOCT Guidance
Demir Arikan, Peiyao Zhang, Michael Sommersperger +7
Robotic platforms provide consistent and precise tool positioning that significantly enhances retinal microsurgery. Integrating such systems with intraoperative optical coherence t…
A Feasible Workflow for Retinal Vein Cannulation in Ex Vivo Porcine Eyes with Robotic Assistance
Peiyao Zhang, Peter Gehlbach, Marin Kobilarov +1
A potential Retinal Vein Occlusion (RVO) treatment involves Retinal Vein Cannulation (RVC), which requires the surgeon to insert a microneedle into the affected retinal vein and ad…
