Purpose: To evaluate the feasibility and usefulness of intraoperative OCT (iOCT) for uveitis-related vitreoretinal surgeries.
Design: Prospective consecutive case series.
Participants: Seventy-three consecutive patients (74 eyes) with a uveitis-related diagnosis.
Methods: Eyes undergoing surgery for a uveitis-related diagnosis in the prospective Determination of Feasibility of Intraoperative Spectral Domain Microscope Combined/Integrated OCT Visualization During En Face Retinal and Ophthalmic Surgery (DISCOVER) iOCT study. Intraoperative OCT was performed at various surgical milestones. Clinical details and evaluation of the role of iOCT were assessed. A standardized surgeon survey was completed to evaluate the usefulness of iOCT during surgery.
Main Outcome Measures: Percentage of patients in whom iOCT provided valuable feedback and altered surgical decision making.
Results: Seventy-four consecutive eyes with a uveitis-related diagnosis were enrolled in the DISCOVER study. Successful imaging was obtained in 72 of 73 eyes (98.6%). Intraoperative OCT provided valuable feedback for fluocinolone acetonide implant placement in 11 of 13 eyes (84.6%), for chorioretinal biopsies in 13 of 16 eyes (81.2%), and for retinal detachment (RD) repairs in 20 of 27 eyes (74.1%). In subretinal and chorioretinal biopsies, iOCT altered surgical decision making in 38% of patients. In uveitis-related RD repairs, iOCT resulted in alterations in the surgical procedure in 48% of patients, predominantly related to additional membrane peeling.
Conclusion: Intraoperative OCT during uveitis-related vitreoretinal surgery seems to provide valuable additional information that can impact surgical decision making and may enhance outcomes.

Intraoperative Augmented Reality for Vitreoretinal Surgery Using Edge Computing.
J Pers Med

: Augmented reality (AR) may allow vitreoretinal surgeons to leverage microscope-integrated digital imaging systems to analyze and highlight key retinal anatomic features in real time, possibly improving safety and precision during surgery. By employing convolutional neural networks (CNNs) for retina vessel segmentation, a retinal coordinate system can be created that allows pre-operative images of capillary non-perfusion or retinal breaks to be digitally aligned and overlayed upon the surgical field in real time. Such technology may be useful in assuring thorough laser treatment of capillary non-perfusion or in using pre-operative optical coherence tomography (OCT) to guide macular surgery when microscope-integrated OCT (MIOCT) is not available.

Background: Pain, as defined by the International Association for the Study of Pain, is an unpleasant sensory and emotional experience associated with, or resembling, that is associated with actual or potential tissue damage. In Ethiopia, where healthcare facilities and offerings are expanding to handle countless patients requiring surgical intervention, managing acute postoperative pain is a serious concern.
Objectives: To assess the prevalence of acute postoperative pain and associated factors after elective surgery among adult patients at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, 2023.
Outcomes of OCT imaging-based reoperations in strabismus.
BMC Ophthalmol
January 2025
Post Graduate Institute of Medical Education and Research, Chandigarh, India.
Purpose: Reoperations in strabismus are reportedly needed in 20-40% of cases undergoing surgery. The present study investigated the outcomes of reoperations based on preoperative imaging of extraocular muscle insertions, and whether the Anterior Segment Optical Coherence Tomography (ASOCT) was of value.
Methods: Patients with strabismus requiring reoperation with/without previous surgical records at the Advanced Eye Centre, PGIMER, Chandigarh were recruited.
Enlightening the invisible: Applications, limits and perspectives of intraoperative fluorescence in neurosurgery.
Brain Spine
October 2024
Department of Neurosurgery, University Hospital of Dijon Bourgogne, Dijon, France.
Introduction: The introduction of intraoperative fluorophores represented a significant advancement in neurosurgical practice. Nowadays they found different applications: in oncology to improve the visualization of tumoral tissue and optimize resection rates and in vascular neurosurgery to assess the exclusion of vascular malformations or the permeability of bypasses, with real-time intraoperative evaluations.
Research Question: A comprehensive knowledge of how fluorophores work is crucial to maximize their benefits and to incorporate them into daily neurosurgical practice.
Patient-Reported Outcomes in Robotic-Assisted vs Manual Cementless Total Knee Arthroplasty.

Department of Orthopaedic Surgery, University of Louisville, Louisville, KY, USA.
Background: Robotic-assisted total knee arthroplasty (RA-TKA) was introduced to provide surgeons with virtual preoperative planning and intraoperative information to achieve the desired surgical goals in an effort to improve patient outcomes. The purpose of this study was to compare clinical outcomes and patient-reported outcome measures following primary TKA using RA-TKA vs manual instrumentation.
Methods: This was a retrospective cohort review study comparing 393 primary RA-TKAs vs 312 manual TKAs at a minimum 2-year follow-up.
