OCT angiography in glaucoma
Evidence for a vascular component and the impact of ocular perfusion pressure on glaucoma
Professor Vital P. Costa
Prof Costa discussed the challenges and limitations of different studies (experimental, cross-sectional, and longitudinal) and current techniques employed in the evaluation of ocular blood flow. Whilst OPP is considered a surrogate for ocular blood flow; its estimation is however influenced by several factors that affect the measurements of IOP, blood pressure, blood viscosity and vessel diameter. He reckons that OCTA imaging modality may better demonstrate the associations between ocular blood flow and glaucoma.
Principles and scanning protocols of OCT angiography
Dr Kaweh Mansouri
Dr Kaweh Mansouri reiterated the poorly understood vascular theory of glaucoma that is mainly due to the limitations of the available tools and techniques to evaluate ocular blood flow. Dr Mansouri then discussed the principles and advantages of the OCTA including an ability to visualize the different layers of vasculature from the superficial retinal layers to the choroid, and to perform quantitative estimations of the areas occupied by vessels. He ended the talk by illustrating potential ... Keep reading
