WebThe optic nerve was centered in a vertical axial view for examination of optic disc drusen. Buried drusen were diagnosed if a highly reflective echographic signal persisted as the gain was decreased from 75 to <27 dB (10-MHz probe, I 3 system, ABD, Innovative Imaging Inc., Sacramento, CA). WebBaseline examination of left eye (A–C) showed an elevated optic nerve head and optic disc drusen confirmed by ultrasound, autofluorescence, and OCT (C, yellow arrow). However, the patient has peripapillary wrinkles (PPW) on the en face OCT ( B , white arrows ), and transverse axial showed an anterior (S-shaped) deformation ( C ) with a mean ...

WebUltrasound combines the aforementioned advantages, which can conveniently measure the ODH and ONSD at the bedside. OCT can also be used to assess optic disc drusen, and a study has compared the two. Optic nerve ultrasound remains the most reliable method (Rosa et al., 2024a). WebOptic nerve head drusen (ONHD) are incidental ophthalmologic finding in the optic nerve. Patients with ONHD are often asymptomatic, but sometimes present with transient visual … skull car seat covers

WebMaking an accurate diagnosis of optic disc drusen (ODD) is important as part of the work-up for possible life-threatening optic disc edema. It also is important to follow the slowly progressive visual field defects many patients with ODD experience.
