      Augmented reality offers enhanced visualization and improved ergonomics

      As the medical director of a recently opened retina practice that I launched after many years in a group practice, I was gratified to have the opportunity to be among the first retinal surgeons in the US to perform surgery with the assistance of this platform. When operating with the Beyeonics One system, we viewed the surgical field in 3D through the surgical headset rather than on an external screen, such as those associated with “heads up” surgical systems. The setup places me at a control center, where I can use the platform to access optical coherence tomography images and ...

    2. How to assess if photoreceptors are functioning properly: A new approach for diagnosing eye diseases

      How to assess if photoreceptors are functioning properly: A new approach for diagnosing eye diseases

      Researchers have long been trying to determine if non-functioning photoreceptors can be detected like dead pixels on a camera sensor, and until now this has not been possible. However, a new technique will allow fast and non-invasive assessment of the physiological state of the retina, a potential game-changer in the treatment of eye diseases. For years, electroretinography (ERG) was the only advanced method to assess the physiological state of retinal function. In recent years, a new technique called optoretinography (ORG) has been developed. In one variant of this technique, optical coherence tomography (OCT), the physiological response of the retinal photoreceptors ...

    3. IPL offers glaucoma biomarker for early-stage disease

      IPL offers glaucoma biomarker for early-stage disease

      A sublayer of the inner plexiform layer (IPL) holds promise as a potential biomarker in efforts to detect early glaucomatous changes, according to Zeinab Rozita Ghassabi, MD, a postdoctoral research fellow, and Joel Schuman, MD, Department of Ophthalmology, New York University Langone Health, New York. Ghassabi related that animal studies have determined glaucomatous changes start in dendrites and then in the ganglion cells and axons.

    4. In-home self-monitoring of AMD patients identifies retinal fluid

      In-home self-monitoring of AMD patients identifies retinal fluid

      igh-quality retinal images obtained by patients in their homes using a self-operated optical coherence tomography (OCT) system (Notal Vision Home OCT; Notal Vision) were suitable for reliable identification of retinal fluid by human graders and quantification by an artificial intelligence (AI)-based algorithm, according to Anat Loewenstein, MD. This conclusion was based on a study conducted by Loewenstein and colleagues to determine how well an OCT system designed for at-home use works. Their goal was to “catch and treat” wet retinas as soon as possible.

      Robotics: Allowing surgeons to perform the seemingly impossible

      Medical robots are revolutionizing medicine. Their applications can facilitate superhuman dexterity, enabling the performance of surgical steps otherwise considered impossible and automating repetitive tasks. The benefits include high positional stability, precision, and accuracy along the x-, y-, and z-axes, removal of time constraints on subretinal and intraretinal drug delivery, and reduction of surgeon fatigue, according to Richard B. Rosen, MD, DSC(HON), of the New York Eye and Ear Infirmary of Mount Sinai in New York, New York.

      Physicians' treatment decisions are reinforced with good data

      The best-corrected visual acuity (BCVA) and the central subfield thickness (CST) were moderately negatively correlated in patients with macular edema (ME) resulting from retinal vein occlusion (RVO), diabetic macular edema (DME) , and noninfectious uveitis (NIU) at baseline, and these were similar across all 3 disease states. “In clinical practice, treatment decisions for ME are often based on assessments of the BCVA and the findings on optical coherence tomography [OCT], including CST and presence of fluid. The majority of retina specialists worldwide rely on OCT-guided variable-frequency treatment protocols to treat ME,” said Dilraj S. Grewal, MD, who emphasized the importance of ...

      Teaching AI algorithms to identify corneal pathology: The future is now

      Bustamante and colleagues conducted a study with the goal of training different AI algorithms to discriminate between healthy and diseased corneas by evaluating spectral-domain optical coherence tomography (SD-OCT) corneal images.

      Their prospective, experimental, comparative pilot study included a control group comprised of 71 images of healthy corneas and an experimental group comprised of 22 SD-OCT corneal images of random corneal pathologies that included corneal ectasia, corneal ectasia and cross-linking, active and inactive herpes simplex keratitis, and exposure keratopathy.

      Bustamante explained that in image processing and the intersection with machine learning, extraction of features is crucial in pattern recognition.

    8. Advances in spectral domain 3-D high-resolution OCT

      Spectral domain optical coherence tomography (SD-OCT), the latest generation of the technology, is a breakthrough because it has dramatically cut the time required to obtain images by eliminating the moving mirror that was a component of standard OCT, according to Cynthia Toth, MD. In addition to being 50 times faster than conventional OCT, SD-OCT has improved resolution because of improved processing. Another benefit is decreased patient movement artifact, especially in pediatric patients. "In

      Wolfgang Drexler, PhD, was instrumental in the development of optical coherence tomography (OCT) and has contributed significantly to advances such as ultra high-resolution OCT. But befitting someone who is recognized for his future promise as well as his prior accomplishments, Dr. Drexler has no shortage of ideas for enhancing OCT's value as a clinical and research tool. Dr. Drexler, professor of biomedical engineering at Cardiff University, Wales, received the Cogan Award Tuesday night. Throug
