    Aims: A paucity of literature exists on prevalence of diabetic retinopathy (DR) in sub-Saharan Africa. We aim to estimate the prevalence of DR and visual impairment in Zambia's Copperbelt province through a cross-sectional study.

    Methods: All patients with a diagnosis of diabetes mellitus attending a DR screening programme were eligible to participate. Read More

    Progression of diabetic retinopathy severity after treatment with dexamethasone implant: a 24-month cohort study the 'DR-Pro-DEX Study'.
    Acta Diabetol 2018 Mar 1. Epub 2018 Mar 1.
    Division of Ophthalmology, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.
    Purpose: Intravitreal anti-vascular endothelial growth factor agents have been shown to reduce diabetic retinopathy (DR) progression; data on the effects of intravitreal corticosteroids on modifying disease severity are limited. This study evaluates the long-term effect of intravitreal dexamethasone implant (DEX) on the severity and progression of non-proliferative DR (NPDR).

    Methods: This was a retrospective cohort study. Read More

    Fundus fluorescence Angiography in diagnosing diabetic retinopathy.
    Pak J Med Sci 2017 Nov-Dec;33(6):1328-1332
    Bin Tong, Department of Ophthalmology, Binzhou People's Hospital, Shandong, 256600, China.
    Objective: To investigate the manifestation characteristics of fundus fluorescence angiography (FFA) and its values in diagnosing diabetic retinopathy through comparing direct ophthalmoscopy.

    Methods: Two hundred fifty patients (500 eyes) who were suspected as diabetic retinopathy and admitted to the hospital between February 2015 and December 2016 were selected. They underwent direct ophthalmoscopy and FFA. Read More

    Hybrid wide-angle viewing-endoscopic vitrectomy using a 3D visualization system.
    Clin Ophthalmol 2018 12;12:313-317. Epub 2018 Feb 12.
    Department of Ophthalmology, National Organization Kyoto Medical Center, Kyoto, Japan.
    Purpose: To introduce a hybrid wide-angle viewing-endoscopic vitrectomy, which we have reported, using a 3D visualization system developed recently.

    Subjects And Methods: We report a single center, retrospective, consecutive surgical case series of 113 eyes that underwent 25 G vitrectomy (rhegmatogenous retinal detachment or proliferative vitreoretinopathy, 49 eyes; epiretinal membrane, 18 eyes; proliferative diabetic retinopathy, 17 eyes; vitreous opacity or vitreous hemorrhage, 11 eyes; macular hole, 11 eyes; vitreomacular traction syndrome, 4 eyes; and luxation of intraocular lens, 3 eyes).

    Results: This system was successfully used to perform hybrid vitrectomy in the difficult cases, such as proliferative vitreoretinopathy and proliferative diabetic retinopathy. Read More

    Fractal dimension and lacunarity analysis of retinal microvascular morphology in hypertension and diabetes.
    Microvasc Res 2018 Feb 22;118:36-43. Epub 2018 Feb 22.
    Faculty for Information Systems and Technologies, University of Donja Gorica, Podgorica, Montenegro.
    Hypertension and diabetes mellitus represent modifiable risk factors for vascular disease. They cause microvascular remodeling, and ultimately result in end-organ damage. Therefore, development of methods for noninvasive quantification of the effects of hypertension and diabetes mellitus on microvasculature is of paramount importance. Read More

    Comparison of Subjective Assessment and Precise Quantitative Assessment of Lesion Distribution in Diabetic Retinopathy.
    JAMA Ophthalmol 2018 Feb 22. Epub 2018 Feb 22.
    Doheny Image Reading Center, Doheny Eye Institute, Los Angeles, California.
    Importance: Predominantly peripheral disease in eyes with nonproliferative diabetic retinopathy (DR) is suggested as a potential strong risk factor for progression to proliferative disease. However, the reliability and optimal method for the assessment of lesion distribution are still uncertain.

    Objective: To compare agreement between subjective assessment and precise quantification of lesion burden in ultrawidefield (UWF) images of eyes with DR. Read More

    Ranibizumab-induced retinal reperfusion and regression of neovascularization in diabetic retinopathy: An angiographic illustration.
    Am J Ophthalmol Case Rep 2018 Mar 4;9:41-44. Epub 2018 Jan 4.
    Department of Vitreo-Retina, Giridhar Eye Institute, Ponneth Temple Road, Kadavanthara, Kochi, India.
    Purpose: To report regression of neovascularization and reperfusion of ischemic areas of the retina on Wide-field Digital Fluorescein Angiography following anti-vascular endothelial growth factor injections in a patient with active Proliferative Diabetic Retinopathy.

    Observations: Case report of sixty-one-year-old male patient with proliferative diabetic retinopathy and diabetic macular edema documented on wide field digital fluorescein angiography. The patient was treated with three intravitreal injections of ranibizumab given at monthly intervals. Read More
