    2. Distinct patterns of diabetic maculopathy seen on OCT

      Optical coherence tomography (OCT) is valuable in managing diabetic macular edema (DME), more so than fluorescein angiography, in which the degree of leakage is not correlated with visual acuity and outcomes, according to Peter Kaiser, MD. In addition, angiography does not show vitreoretinal abnormalities that may require a different treatment.

    3. Take a new look at existing devices, surgeon suggests

      London—Advances in optical coherence tomography (OCT) devices, regardless of the manufacturer, are dramatically changing the ease and precision of ocular disease diagnosis and management in ophthalmology. The new technology that these devices wield can offer the clinician much more than what they originally were designed to do in the diagnostics of the anterior eye, lens, and retinal diseases, according to John Bolger, FRCS, surgeon, and founder and director of the Cataract Clinic, London. A Fourier-domain OCT (RTVue-100, Optovue) is one device that uses this new technology, and it is designed to assist in the diagnosis and management of glaucoma ...

    4. Preoperative optical coherence tomography can predict surgical, acuity outcomes

      Osaka, Japan—Patients with high myopia, macular holes, and no retinal detachment have better visual outcomes compared with patients with high myopia, a macular hole, and a localized retinal detachment with surrounding retinoschisis and compared with patients with high myopia with a macular hole and a retinal detachment within the area of posterior staphyloma and no retinoschisis. This assessement is according to Yasushi Ikuno, MD, associate professor, Department of Ophthalmology, Osaka University Medical School, Osaka, Japan. Macular holes, according to Dr. Ikuno, are a major complication in high myopia; vitrectomy with peeling of the internal limiting membrane peeling and gas ...

    6. Ultrasound provides clearer picture of posterior segment

      "Currently available ultrasound techniques can evaluate the cornea to the level of microns. By imaging the sulcus, ciliary body, and lens, the results are superior to OCT imaging," he said. "For retina specialists, this technology is useful for looking at the anterior segment, that is, the ciliary body and the area around the lens. This imaging approach is also useful to diagnose and follow patients with tumors to determine if treatment with an iodine or other radioactive plaque is necessary or, if used, was effective. However, the posterior segment cannot be visualized using high frequencies because of ultrasound absorption, thus ...

    8. Automated system separates glaucomatous, healthy eyes

      An automated glaucoma risk indicator using digital color fundus photos proved to be accurate in the detection of glaucoma disease in a recent study. This novel technique is not intended to replace other state-of-the-art diagnostic techniques currently used . Ophthalmologists, however, can receive a confirmation from this automated diagnosing system that the diagnosis they are making in regards to glaucoma is the right one.

    9. Fourier-domain optical coherence tomography allows improved visualization of retinal layers

      Sacramento, CA—Fourier-domain optical coherence tomography (OCT) is a new technology that enables improved visualization of the retinal layers, especially the photoreceptor layer. This technology, also known as spectral-domain OCT, is sensitive enough to facilitate the diagnosis of maculopathy in eyes with vision loss unexplained using routine diagnostic tests, such as funduscopy, fluorescein angiography, and time-domain OCT technology (Stratus OCT, Carl Zeiss Meditec). So says Susanna S. Park, MD, PhD, who with colleagues used for research a high-resolution Fourier-domain OCT instrument developed by the Vision Science and Advanced Retinal Imaging Laboratory at the University of California Davis. The system differs ...
