What Is a B-Scan?
A B-scan, or brightness scan, is a non-invasive ultrasound imaging procedure that uses sound waves to create detailed cross-sectional images of the eye. This technique is especially valuable when the view of the retina is obscured by conditions like dense cataracts, vitreous hemorrhage, or other opacities.
Conditions Diagnosed with B-Scans:
- Retinal detachment
- Vitreous hemorrhage
- Ocular tumors or masses
- Intraocular foreign bodies
- Severe eye trauma
- Endophthalmitis (eye infection)
How B-Scans Work
B-scans use high-frequency sound waves to produce real-time images of the eye’s internal structures. During the procedure:
- Preparation: The eye is numbed with anesthetic drops, and a gel is applied to the closed eyelid to facilitate the ultrasound probe’s movement.
- Imaging: The probe emits sound waves that bounce off internal eye structures, creating detailed images on a monitor.
- Analysis: The images are analyzed by the retina specialist to diagnose or monitor conditions.
What to Expect During a B-Scan Procedure
- Non-Invasive: The procedure is painless and does not require any incisions.
- Quick and Efficient: Most B-scans take less than 15 minutes to complete.
- Comfortable Setting: Our skilled technicians ensure your comfort throughout the process.
Benefits of B-Scans
- Provides detailed imaging when traditional methods (e.g., OCT) are not feasible
- Detects hidden or obscured retinal conditions
- Safe for all patients, including those with complex eye conditions
- Quick, painless, and non-invasive
