ABSTRACT
In the posterior eye, OCT has been used to identify all the major surface and subsurface retinal features in a highly reproducible fashion. Figure 15.1 shows a comparison between retinal images using a swept source at 1050 nm and a spectral domain (SD)-OCT system at 840 nm (Lee et al. 2006). OCT retinal imaging has been used as a tool to diagnose and investigate macular hole formation (Michalewska et al. 2009), macular edema, which is correlated with diabetic retinopathy (Hannouche and de Avila 2009), and age-related macular degeneration (de Bruin et al. 2008). In addition, measurements of the retinal nerve ›ber layer (RNFL) (Cense et al. 2004, Anderson et al. 2005), a key indicator of glaucomatous damage have become an important tool for detecting and monitoring glaucoma, a leading cause of blindness worldwide.
