Retina Vitreous · Retinal detachment

Retinal detachment B scan

B-scan ultrasonography is essential when media opacity (e.g., vitreous hemorrhage, dense cataract) precludes fundus visualization. It enables assessment of the retina in the presence of vitreous hemorrhage or other media opacity, and is used to diagnose diabetic retinal detachments and define the extent and severity of vitreoretinal traction in these settings.The detached retina appears as a bright, mobile, & echogenic membrane tethered to the optic disc but separated from the choroid, and this appearance on ultrasonography is both highly sensitive and specific for retinal detachment. The membrane’s mobility and folding are best appreciated during kinetic examination, where the patient moves the eye and the detached retina undulates, remaining anchored at the optic nerve head.
