WebDec 13, 2024 · B-mode ultrasonography has generally been considered a highly sensitive imaging tool for the identification of optic nerve drusen. A newer method for drusen diagnosis is optical coherence tomography, particularly EDI-OCT and SS-OCT, which may show irregular or spheroidal hypo reflective structures in a case of drusen ( 11, 23, 24 ). WebOptical coherence tomography is a non-contact, high-resolution, in vivo imaging modality. It produces cross-sectional tomographic images just like ultrasound. Decreased OCT image quality can be attributable to cataracts which block light, patient motion artifact, or …
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. WebB scan is very sensitive in detecting small optic nerve calcifications as it happens in cases of optic nerve drusen (5) but is not so reliable in case of measurements (6). Among the reasons for this poor reliability there is that with B scan the optic nerve is visualized as a low reflective band behind the globe. This makes the mea-
