    1. Morphological and functional changes in spectral domain optical coherence tomography and microperimetry in macular microhole variants: Spectral domain optical coherence tomography and microperimetry correlation

      Morphological and functional changes in spectral domain optical coherence tomography and microperimetry in macular microhole variants: Spectral domain optical coherence tomography and microperimetry correlation
      Purpose: To evaluate the relationship between the morphology and retinal function of macular microhole (MMH) variants. Materials and Methods: We evaluated 12 eyes of 11 patients with defects in the IS/OS junction of photoreceptor layer with SD-OCT. All patients underwent comprehensive ophthalmic examination including spectral domain optical coherence tomography (SD-OCT) and microperimetry. Results: The mean logMAR visual acuity in the affected eye was 0.15 ± 0.17 (range 0.00-0.5). Mean horizontal diameter of the MMH was 163 ± 99 μm; the mean retinal sensitivity in the area corresponding to the MMH was 13.79 ± 4.6 dB. Negative ...

    2. Spectral domain optical coherence tomography and microperimetry in foveal hypoplasia

      Spectral domain optical coherence tomography and microperimetry in foveal hypoplasia
      A case of foveal hypoplasia associated with ocular albinism with anatomic and functional changes by various techniques using spectral domain optical coherence tomography (SD-OCT), microperimeter and confocal scanning laser ophthalmoscope is described. This case highlights the importance of microperimeter in detecting the functional abnormalities of vision and SD-OCT in identifying the retinal laminar abnormalities in foveal hypoplasia.

    3. High-resolution optical coherence tomography correlates in ischemic radiation retinopathy

      Purpose: To find the abnormalities in various retinal layers caused by radiation retinopathy using spectral domain optical coherence tomography (SD-OCT). Methods: We report a case of radiation retinopathy that was imaged using SD-OCT Copernicus (Optopol, Zawiercie, Poland). Analysis and synthesis of the OCT image were done using information both at the fovea and 2.5mm temporal to the fovea. Results: The layers that were reduced in thickness included the inner plexiform layer (47μm vs. 74μm), the inner nuclear layer (17μm vs. 48μm), and the outer plexiform layer (25μm vs. 45μm), whereas the layers with comparable thickness included the nerve fiber ...

    4. Spectral-Domain OCT and Microperimeter Characterization of Morphological and Functional Changes in X-linked Retinoschisis

      A case of X-linked retinoschisis with anatomic and functional issues correlated by a constellation of methods, including spectral-domain optical coherence tomography, microperimeter, electroretinography, and multifocal electroretinography, is described. This case highlights the importance of microperimetry in the presence of normal or subtle abnormalities in full-field electroretinography. The ability of spectral-domain optical coherence tomography in diagnosis and follow-up in cases with X-linked retinoschisis is demonstrated. [Ophthalmic Surg Lasers Imaging 2009;40:71-74.]
