B-scan Ultrasound plays an important role in the diagnosis and management of various intraocular disorders in both clear and opaque ocular media.
The ocular ultrasound is an imaging technique that uses high-frequency sound waves that can be used instead of light to create an image of the retina and the surrounding structures.
The technique is used to identify complications of diabetic retinopathy including vitreous traction, retinal detachment and blood beneath the retina.
In addition to its use in the detection of obscured pathologies, B-scan ultrasound is frequently used for the characterization of clearly visible pathologies.
Some examples include: differentiating rhegmatogenous from exudative retinal detachments; differentiating drusen from papilledema; and determining intraocular tumor type.
