OCT angiography discriminates between POAG, NTG and normal patients

November 2016

The first three papers describing OCT angiography (OCT-A) didn’t examine the vasculature of the eye with the technology, they examined blood flow in the outer layers of the brains of rats (1)(2)(3). It was actually the fourth that examined the human eye; in 2012, Jia et al. (4) compared optic nerve head (ONH) flow in patients with preperimetric glaucoma (PPG; n=4) with normal subjects (n=4), and found that ONH flow was significantly lower in the PPG group.

About the author

Mark Hillen

Before joining Texere Publishing as Editor of The Ophthalmologist, I spent seven years as a medical writer, writing primary and review manuscripts, congress presentations and marketing materials for numerous – and mostly German – pharmaceutical companies. Prior to my adventures in medical communications, I was a Wellcome Trust PhD student at the University of Edinburgh, where I examined mouse brain development. I miss my labcoat, pipette, peristaltic pumps and PCR machines, but I have grown to love my laptop, keyboard, mouse and rotating monitors even more.

Welcome to the November issue of The Ophthalmologist. Upfront includes news on how the Mediterranean diet protects against AMD, reports on a study on whether ILM peels really improve outcomes in ERM surgery, and the use of OCT-A for monitoring, diagnosing and staging glaucoma. In My View features Philip Rosenfeld on the importance of getting clinical trial designs right – getting it wrong impacts everyone – and Ivan Goldberg highlights the issue of patient non-adherence in glaucoma management. Our cover feature sees BJ Dupps herald a revolution in refractive surgery, driven by precision corneal biometry, biomechanics, and computer simulation. In Practice sees Paul Tornambe review pneumatic retinopexy, and in NextGen, Luca Gualdi describes an electrifying new workout for the ciliary muscles as an early presbyopia treatment. Profession sees Dawn Sim explain why ophthalmology needs to see the bigger picture and implement new technologies to improve patient care, and finally, we Sit Down With co-inventor of OCT, and totally COOL guy, David Huang.
