    2. Diabetic vascular hyperpermeability: optical coherence tomography angiography and functional loss assessments of relationships among retinal vasculature changes

      Diabetic vascular hyperpermeability: optical coherence tomography angiography and functional loss assessments of relationships among retinal vasculature changes
      Our study assessed the influence of vascular permeability on vascular flow density (FD)-correlated retinal sensitivity (RS) in DR. In this cross-sectional, prospective, consecutive study, RS in the extrafoveal macula of DR patient was measured by microperimetry. FD was measured in the total, superficial, and deep capillary plexus layers (TCP, SCP, and DCP) by optical coherence tomography angiography. All measurement points were classified into four categories according to intensity of ...

    3. Direct comparison of retinal structure and function in retinitis pigmentosa by co-registering microperimetry and optical coherence tomography

      Direct comparison of retinal structure and function in retinitis pigmentosa by co-registering microperimetry and optical coherence tomography
      Purpose To evaluate the retinal structure-function relationships in the macula of retinitis pigmentosa (RP) patients by comparing microperimetry-3 (MP-3) images with co-registered optical coherence tomography (OCT) images. Methods Thirty patients with typical RP were recruited from our hospital. The maculae of patients were examined with MP-3 and OCT. The retinal sensitivity was measured by MP-3 at 40 testing points arranged concentrically in a 16 diameter of the central retina, and ...

    4. Microaneurysm Imaging using Multiple En Face Optical Coherence Tomography Angiography Image Averaging: Morphology and Visualization

      Microaneurysm Imaging using Multiple En Face Optical Coherence Tomography Angiography Image Averaging: Morphology and Visualization
      Purpose In diabetic retinopathy (DR), optical coherence tomography angiography (OCTA) could not image all fluorescein angiography (FA)-detected microaneurysms. We investigated if multiple image averaging could enhance its microaneurysm detection capability in DR. Design Prospective- and cross-sectional observational study. Participants Consecutive 31 patients (n = 62 eyes) with DR. Methods All eyes underwent FA, and 3 x 3 mm fovea-centered OCTA images were obtained using two devices (RTVue XR Avanti: Optovue ...

    5. Optical Coherence Tomography Angiography Detects Choriocapillaris Loss in Decalcification of Choroidal Osteoma

      Optical Coherence Tomography Angiography Detects Choriocapillaris Loss in Decalcification of Choroidal Osteoma
      Purpose: Choroidal osteoma, which typically affects young women, is a benign intraocular tumor composed of mature bone within the choroid. Tumor decalcification and subfoveal choroidal neovascularization often lead to poor visual acuity although the etiology is unknown. Choriocapillaris characteristics in choroidal osteoma also are unknown. Methods: We report 4 cases of choroidal osteoma with decalcification in which the choriocapillaris could be imaged by optical coherence tomography angiography (OCTA). Results: OCTA ...

    6. Flow Density in Optical Coherence Tomography Angiography is Useful for Retinopathy Diagnosis in Diabetic Patients

      Flow Density in Optical Coherence Tomography Angiography is Useful for Retinopathy Diagnosis in Diabetic Patients
      Our study evaluated the diagnostic capability of flow density (FD) in OCT angiography (OCTA) for diabetic retinopathy (DR) detection in diabetic patients. We studied 93 eyes of 68 diabetic patients who underwent OCTA (36 and 57 eyes without and with DR, respectively). Retinal capillary FD of a 2.62.6 mm 2 area and four divided areas at the superficial (SCP) and deep capillary plexus (DCP) were measured. Predictions were ...

    7. Optical Coherence Tomography Angiography Reveals Spatial Bias of Macular Capillary Dropout in Diabetic Retinopathy

      Optical Coherence Tomography Angiography Reveals Spatial Bias of Macular Capillary Dropout in Diabetic Retinopathy
      Purpose : Our purpose is to evaluate the spatial bias of macular capillary dropout accompanying diabetic retinopathy (DR) using optical coherence tomography angiography (OCTA). Methods : This study included 47 patients with diabetes and 29 healthy individuals who underwent OCTA. Retinal capillary flow density (FD) of 2.6 2.6 or 5.2 5.2 mm foveal area as well as the four divided areas (superior, inferior, temporal, nasal) without a foveal ...

    8. Optical Coherence Tomography Angiography for Detecting Choroidal Neovascularization Secondary to Punctate Inner Choroidopathy

      Optical Coherence Tomography Angiography for Detecting Choroidal Neovascularization Secondary to Punctate Inner Choroidopathy
      Punctate inner choroidopathy (PIC) is a relatively uncommon inflammatory multifocal chorioretinopathy that predominantly affects young, myopic women. Subfoveal choroidal neovascularization (CNV) often leads to rapid loss of sight. Fluorescein angiography (FA) and indocyanine green angiography (ICGA) remain the existing gold standards for CNV diagnosis. However, these methods are invasive and time-consuming. Recently, optical coherence tomography angiography (OCTA) has been used more frequently as an adjunct to FA/ICGA. In this ...

    9. OCT Predicts VEGF Levels in Human Eyes

      OCT Predicts VEGF Levels in Human Eyes
      Sonoda et al . 1 reported a new aspect of diagnostic imaging by optical coherence tomography (OCT) in their manuscript, Correlation between reflectivity of subretinal fluid in OCT images and concentration of intravitreal VEGF in eyes with diabetic macular edema. Neudorfer and the authors found that OCT reflectivity is variable in subretinal fluid in diabetic macula edema cases. 2 They have already reported the cytokine profiles in diabetic retinopathy cases from ...

  2. About Kyushu University

    Kyushu University

    Kyushu University dates back to 1903 when Fukuoka Medical College was established as the foundation of Kyushu Imperial University. (The college was legally attached to Kyoto Imperial University at that time). In 1911, Kyushu Imperial University, along with the Colleges of Medicine and Engineering, were established. Since then various reforms have been made to the higher education system in Japan, such as the introduction of a new educational format after World War II and the reorganization of national universities to University Corporations in 2004. The total number of students currently amounts to 18,765, while the faculty members number 2,186. International exchange programs are also greatly encouraged at Kyushu University. With this in mind, the university accepts many overseas students each year. At present there are more than 1,700 international students from about eighty countries studying here.
