OCT Casebook: Starting out

In the last few casebooks, we have outlined how a sensible approach for a first (or screening) OCT assessment would be to undertake a line scan (horizontal and vertical), a volume scan and a scan around the disc.

HH is a healthy, 28-year-old myope (around -3.00/-050 each eye). Other points of relevance here are that HH is a soft lens wearer, has had one episode of microbial keratitis two years ago, and has some dry eye symptoms. As we will see in a later casebook, poor tear flow has an influence on OCT accuracy, and also anterior OCT is a useful way of looking at corneal scarring. For this routine appointment, however, we followed our ‘routine’ protocol.
