WebThrough the use of optical coherence tomography (OCT), a new imaging technique that allows high-resolution (approximately 10 microns) cross-sectional imaging of the eye using infrared light, we were able to evaluate the nerve fiber layer (NFL) in these patients with uninterpretable optic nerve heads. WebOCT has become increasingly useful as an adjunctive tool in the detection of optic disc drusen (ODD) and the workup for possible papilledema. ODD must have two key characteristics: They should be above the lamina cribrosa, and they should have a hyporeflective core.
