Optic nerve drusen oct image
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- WebJul 15, 2024 · As technology improves, OCT is increasingly used in the diagnosis of optic disc drusen. The ODDS Consortium recommends the use of enhanced-depth OCT imaging for adequate visualization of disc drusen. With OCT, the optic disc drusen appear as hyporeflective structures with a hyper-reflective margin.
