OCT Casebook: Initial results

At the conclusion of our last casebook series, we had looked at the main options for scanning a patient with an OCT and concluded with an assessment of a routine patient, HH (Optician 24.7.20). In this next series we will focus on the data gained from a range of patients and begin with a look at HH, a young patient about whom there were no concerns and who had OCT scanning as a matter of routine.

The horizontal line scans for the right eye (figure 1) and the left eye (figure 2) offer a clear view of a cross section of each retina and represent a healthy and normal appearance. The visibility of posterior vitreous, particularly around the temporal disc area, and the obviously thick section of choroid and choriocapillary tissue underneath the retina remind us that this is a younger patient (28 years). Layers tend to thin with age, and vitreous becomes more fluid and eventually invisible on OCT scan.
