Posterior Staphyloma

OCT Features:

The appearance of a posterior staphyloma on OCT is rather striking compared to the more subtle clinical appearance. OCT reveals significant posterior bowing and curvature of the posterior eye wall, including the sclera and overlying choroid and retinal layers (Fig. 9.1.2). The choroid is typically almost imperceptible due to significant thinning.

Figure 9.1.2 OCT (corresponding to Figure 9.1.1) shows dramatic posterior bowing of the eye wall. The choroid is so thin that it is barely appreciable. The RPE layer has focal disruptions. The retina takes on the same curvature as the sclera. There is also a mild dome-shaped macula present (see Chapter 9.4, Dome-Shaped Macula)
