I agree with Les Clarke’s view that to refer into the NHS an optometrist needs a basic OCT, scanning laser ophthalmoscope and a slit lamp. In addition, the optometrist needs confidence to interpret the images and that comes with a thorough learning regime.
However, what constitutes a ‘basic’ OCT? Does basic mean ‘inexpensive’? Does basic mean ‘imprecise’? I would argue that a basic OCT should offer a diagnostic quality SLO fundus image, simultaneously registered with a high-resolution OCT scan, positioned automatically in exactly the same location for each follow-up scan. These three basics ensure accurate measurement of change over time. No fancy bells and whistles required, simply one micron of accuracy so that nothing is missed.
To position the practice to take advantage of shared care opportunities and revenue from enhanced clinical services in future, an upgradeable OCT platform is a particularly smart investment.
