7. Retinal Microvascular Change in Hypertension as measured by Optical Coherence Tomography Angiography
  
  Explore Nature Publishing Group Jan 28 2019 Ophthalmology
  
  Many studies have reported the effect of hypertension on microcirculation of the retina. Advance of optical coherence tomography angiography (OCTA) allows us more detailed observations of microcirculation of the retina. Therefore, we compared OCTA parameters between chronic hypertension (disease duration of at least 10yrs; Group A, 45 eyes), relieved hypertensive retinopathy (grade IV HTNR1yr prior; Group B, 40 eyes), and normal controls [Group C (50 eyes)50yrs old and Group ...

9. Long-term reproducibility of GC-IPL thickness measurements using spectral domain optical coherence tomography in eyes with high myopia
  
  Explore Nature Publishing Group Jul 28 2018 Ophthalmology
  
  Although ganglion cell inner plexiform layer (GC-IPL) analysis in the patients with high myopia is useful, there have been few reports to analyze of the reliability for long-term measured GC-IPL thickness. We aimed to analyze the long-term reproducibility of thickness measurements of the GC-IPL using spectral-domain optical coherence tomography (SD-OCT) in patients with high myopia and identify factors that affect such reproducibility. 99 eyes from 99 patients with high myopia ...

  Aim To analyse the repeatability of vessel density (VD) measurements using optical coherence tomography angiography (OCTA) in patients with retinal diseases. Methods Two consecutive VD measurements using OCTA were analysed prospectively in patients with retinal diseases (diabetic macular oedema (DME), retinal vein occlusion (RVO) with macular oedema, epiretinal membrane (ERM), wet age-related macular degeneration (AMD)). The intraclass correlation coefficient (ICC), coefficient of variation (CV) and test-retest SD of VD measurements ...

17. Spontaneous resolution of foveal cysts associated with X-linked retinoschisis as observed by optical coherence tomography
  
  Explore NRC Research Press Publishing Services May 28 2010 Ophthalmology
  
  X-linked retinoschisis (XLRS) is an inherited disorder characterized by splitting of the retinal layer. There are no known effective therapeutic interventions for patients with XLRS. In recent years, however, the use of carbonic anhydrase inhibitors and vitrectomy have been reported to be effective in reducing foveal retinoschisis. We encountered a case of XLRS in which spontaneous regression was observed by means of optical coherence tomography (OCT). A 22-year-old male presented ...
