OCT angiography a promising imaging modality for evaluation of microvasculopathy
OCT angiography, or OCT-A, was recently developed to provide three-dimensional noninvasive viewing of the retinal and choroidal vasculature and blood flow estimation at the microcirculation level. OCT-A is based on mapping erythrocyte movement over time by comparing sequential OCT B-scans at a given cross-section. OCT-A has now been explored to study different eye diseases including choroidal neovascularization, polypoidal choroidal vasculopathy, diabetic retinopathy, macular telangiectasia, glaucoma and retinal venous occlusion. This is an exciting era in evaluation of microvasculopathy.
Post-Ebola syndrome poses threat of ocular complications
Ebola hemorrhagic fever is a deadly disease caused by several species of Ebolavirus, a RNA virus of the Filoviridae family. This virus outbreak continues to affect different parts of Africa, and an outbreak reported in the Democratic Republic of the Congo in 1995 had only 71 survivors out of 316 cases. Human-to-human transmission is known to occur through exposure to body fluids. The current outbreak, which began in 2014, affected a greater number of people than ever before. The disease usually starts with nonspecific findings such as fever, weakness, diarrhea, vomiting, abdominal pain, headaches and myalgias, and in severe cases can lead to hemorrhagic manifestations.
