The Education Committee carefully selects presentations from the World Glaucoma Congress 2017 in Helsinki for your benefit. This edition Monisha Nongpiur gives the introductions for the sessions Normal tension glaucoma: pathogenesis, progression and treatment and OCT angiography in glaucoma. 

Normal tension glaucoma

Ocular blood flow: How does ocular blood flow influence the course of glaucoma?
Professor Alon Harris
Prof Harris spoke about the role of vascular risk factors in glaucoma. He highlighted the associations of disc haemorrhage (DH) and ocular blood flow with disease progression in NTG, and described the presumed vascular and mechanical theories for the pathogenesis of DH.  He also talked about the non-ocular vascular abnormalities in subjects with glaucoma. Prof Harris then presented a physically-based mathematical model that incorporated biomechanics and blood flow parameters, to better explain the vascular role in glaucoma and predict blood flow changes.
 
The Low-Pressure Glaucoma Treatment Study (LOGTS) Revisited.
Professor Robert Ritch
Prof Robert Ritch provided an update on the LOGTS trial, which was conducted 18 years ago comparing 0.2% brimonidine with 0.5% timolol. The primary goals of the study was to identify risk factors associated with progression in NTG. One of the significant outcomes from the study was the possibility of a neuroprotective action of brimonidine; and the prospects for IOP-independent treatment ... Keep reading

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
