    How Intrasurgical OCT can Impact the Surgical Approach to Membrane Peeling

    When treating patients with vitreomacular traction (VMT), peeling of the inner limiting membrane (ILM) or an epiretinal membrane (ERM) is often indicated. Successful outcomes depend on precise surgical maneuvers as well as the surgeon’s experience in order to assess whether the entire membrane has been removed, as this is crucial for successful release of traction. Showing different steps of removing an ERM to resolve VMT, the following videos captured with EnFocus intrasurgical OCT demonstrate how visualization of the membrane can impact the surgical process of membrane peeling.

    What is OCT and how can it help ophthalmologists acquire high resolution information on ocular tissue?

    Optical Coherence Tomography (OCT) is a non-invasive, non-contact imaging modality used to visualize and monitor changes to the morphology of biological tissue. OCT employs low-coherence interferometry to create cross-sectional images that reveal sub-surface details of the tissues of interest. In the most common ophthalmic applications OCT systems use near-infrared light to generate high-resolution, volumetric images of tissue microstructures including the cornea, iris, crystalline lens, vitreous and retina. These images can enhance insight into pathological conditions such as glaucoma, age-related macular degeneration or diabetic retinopathy.

  • The Value of Intraoperative OCT Imaging in Vitreoretinal Surgery
    Science Lab Topic: Optical Coherence Tomography

    The Value of Intraoperative OCT Imaging in Vitreoretinal Surgery

    The role of iOCT in vitreoretinal surgery continues to be defined by active research and enhancements to integrative technologies. Further research is needed to better define the specific applications of iOCT that impact patient outcomes and surgical decision-making. Future advancements in integrative systems, OCT-friendly instrumentation, and software algorithms will further expand the horizon of iOCT in the vitreoretinal surgical theater. As OCT transformed the clinical management of the vitreoretinal conditions, iOCT has the potential to be a paradigm-shifting technology in the operating room.

    Handheld Optical Coherence Tomography During Sedation in Young Children With Optic Pathway Gliomas

    Monitoring young children with optic pathway gliomas (OPGs) for visual deterioration can be difficult owing to age-related noncompliance. Optical coherence tomography (OCT) measures of retinal nerve fiber layer (RNFL) thickness have been proposed as a surrogate marker of vision but this technique is also limited by patient cooperation. To determine whether measures of circumpapillary RNFL thickness, acquired with handheld OCT (HH-OCT) during sedation, can differentiate between young children with and without vision loss from OPGs.
