Evaluation of (Shared) Autonomy in Robot-Assisted Vitreoretinal Surgery Using a Surgical Model.
Int J Med Robot
February 2025
Department of Mechanical Engineering, The University of Tokyo, Bunkyo, Japan.
Background: Robot-assisted vitreoretinal surgery makes it easier for the surgeons to perform precise and dexterous manipulations required in vitreoretinal procedures.
Methods: We systematically evaluated manual surgery, conventional two-hand teleoperation, a novel one-hand teleoperation, and automation in a needle positioning task using a realistic surgical eye model, measuring the expert surgeon's performances and the novice's learning curves.
Results: The proposed one-hand teleoperation improved the positioning accuracy of expert surgeons , enabled novices to achieve a consistent accuracy more quickly , decreased the novice's workload more quickly , and made it easier for novices to learn to conduct the task quickly .
Sub-Tenon's Block in Patients with Previous Encircling Band Surgery-A Feasibility Study.
J Clin Med

During the COVID-19 pandemic, reducing aerosol-generating procedures became fundamental, particularly in ophthalmic surgeries traditionally performed under general anesthesia (GA). Regional anesthesia, such as sub-Tenon's block (STB), is widely used in vitreoretinal surgeries, offering a safer alternative by avoiding airway manipulation. However, the altered orbital anatomy in patients with previous scleral explant surgery creates unique challenges to STB application.

Department of Retina and Vitreous, University of Pittsburgh School of Medicine, Medical Retina and Vitreoretinal Surgery, Pittsburg, PA, USA.
Purpose: To evaluate various supervised machine learning (ML) statistical models to predict anatomical outcomes after macular hole (MH) surgery using preoperative optical coherence tomography (OCT) features.
Methods: This retrospective study analyzed OCT data from idiopathic MH eyes at baseline and at 1-month post-surgery. The dataset was split 80:20 between training and testing.
Diagnostic ability of confocal scanning ophthalmoscope for the detection of concurrent retinal disease in eyes with asteroid hyalosis.
PLoS One
December 2024
Department of Ophthalmology, Biomedical Research Institute, Pusan National University Hospital, Pusan National University School of Medicine, Busan, South Korea.
Article Synopsis
- * Researchers analyzed medical records of 100 eyes with AH, finding that 76 had other retinal diseases; TC-cSO showed the best results, with 94% of images having minimal obscuration from asteroid bodies.
- * TC-cSO outperformed the other devices in accuracy (95%) and sensitivity (81%) for diagnosing retinal conditions, making it an effective alternative for screening when
Diagnostic Accuracy of B-Scan Ultrasonography in Detecting Vitreoretinal Pathology after Open-Globe Injury.
Ophthalmol Retina
November 2024
Department of Ophthalmology and Visual Sciences, Carver College of Medicine, University of Iowa, Iowa City, Iowa. Electronic address:
Article Synopsis
- The study aimed to evaluate how accurately B-scan ultrasonography detects vitreoretinal issues after open-globe injury (OGI) repair, using findings from later surgeries as a reference.
- Researchers analyzed 62 eyes from 61 patients at the University of Iowa Hospitals and Clinics over a five-year period, focusing on various vitreoretinal conditions like vitreous hemorrhage and retinal detachment.
- Results showed that while B-scan was good at identifying vitreous hemorrhage, it had significant limitations in diagnosing other issues, indicating that it should not be solely relied upon for detecting serious pathologies.
