    3. Preservation of the Photoreceptor Layer following Subthreshold Laser Treatment for Diabetic Macular Edema as Demonstrated by SD-OCT

      Preservation of the Photoreceptor Layer following Subthreshold Laser Treatment for Diabetic Macular Edema as Demonstrated by SD-OCT

      Purpose: Subthreshold laser treatment of diabetic macular edema (DME) may have less deleterious effects on the photoreceptors than regular continuous wave laser. This study aimed to assess whether subthreshold laser causes a long-term damage to the retinal structures, as demonstrated by spectral-domain optical coherence tomography (SD-OCT), and to evaluate the change in the axial diameter of retinal diabetic microaneurysms following treatment. Methods: A retrospective study of eyes that were diagnosed with non-foveal involving DME and underwent subthreshold laser treatment with the Lumenis Novus SRT system. SD-OCT scans of treated retinal areas, performed prior to treatment and approximately 4 months following ...

      Optical Coherence Tomography Characteristics of Eyes with Acute Anterior Uveitis

      Background: Acute, as opposed to chronic, anterior uveitis is rarely associated with macular or optic nerve edema. Nevertheless, mild changes may not be visible on examination. Objectives: To implement non-invasive ocular coherence tomography (OCT) for obtaining quantitative and qualitative data in the assessment of changes in macular morphology and peripapillary retinal nerve fiber layers in eyes with acute anterior uveitis. Methods: This retrospective case-control study was conducted in patients with unilateral acute anterior uveitis lasting for up to one month. Patients with evidence of other ocular disease or who had undergone intraocular surgery were excluded. We reviewed the charts of ...
