Clinical Overview & Treatment Method
Ophthalmic Ultrasonography (B-Scan) is an indispensable high-frequency acoustic diagnostic tool that enables cross-sectional visualization of the internal structures of the eyeball and orbit. When normal optical visualization of the retina is blocked by dense cataracts, corneal opacities, hyphema (blood in the anterior chamber), or massive vitreous hemorrhage, the USG B-Scan acts as the ophthalmologist's 'acoustic eyes,' providing clear acoustic slices of the posterior segment.
At Ashvini Netralaya, our ultrasound laboratory is equipped with high-resolution 10MHz and 20MHz precision ophthalmic probes. Our skilled ultrasonologists evaluate retinal status (ruling out hidden retinal detachments), detect intraocular foreign bodies following industrial or road accidents, assess posterior vitreous detachment (PVD), diagnose choroidal tumors, and measure vitreous membrane density before planning cataract or vitrectomy surgeries.

Who is an Ideal Candidate for this Procedure?
USG B-Scan vs Optical Diagnostics at Ashvini Netralaya
Understanding when ultrasound imaging is essential compared to optical imaging.
| Option / Type | Vision Range | Night Glare | Spectacle Freedom | Ideal Candidate |
|---|---|---|---|---|
USG B-Scan (Sound Waves) Penetrates Dense Media | Penetrates through opaque cataracts, dense blood & corneal scars | None (uses sound frequencies) | Diagnostic evaluation only | Dense cataracts, vitreous hemorrhage, trauma, foreign bodies |
Optical Coherence Tomography (OCT) High Resolution Optical | Ultra-high 5-micron cellular resolution, but requires CLEAR media | None | Diagnostic evaluation only | Macular holes, DME, glaucoma RNFL (when lens is clear) |
Standard Fundus Photography Surface Color Only | Surface color view of retina, blocked by haze or blood | Temporary flash | Diagnostic only | Routine diabetic & hypertensive retinal documentation |
Step-by-Step Procedure at Ashvini Netralaya
Conducted in our modular NABH-accredited operating theatres or diagnostic laboratories with zero-infection sterilization protocols.
Patient Comfort & Positioning
2 minsYou recline comfortably in an examination chair. Anesthetic drops are applied if scanning directly on the eye surface, or sterile coupling gel is placed over closed eyelids.
Acoustic Coupling Gel Application
1 minHypoallergenic, water-soluble ultrasound gel is applied to the smooth probe tip to ensure seamless sound wave transmission without air bubbles.
Multi-Vector Sectoral Acoustic Scanning
7 minsThe ultrasonologist gently places the probe and asks you to look in multiple directions (up, down, left, right) to image all 4 retinal quadrants.
Dynamic Kinetic Assessment
3 minsYou make small rapid eye movements while the probe records acoustic waveforms to differentiate between mobile vitreous strands and rigid retinal detachments.
Image Capture & Reporting
3 minsHigh-resolution cross-sectional acoustic captures are labeled, measured, and printed alongside a comprehensive clinical report.
Recovery Timeline & Visual Milestones
Gel Cleansing & Normal Routine
The ultrasound gel is gently wiped clean with a sterile tissue. You can immediately open your eyes and return to normal daily tasks.
- Wipe eye with sterile wipe
- Receive printed ultrasound scan
- Resume all normal activities
Surgical Planning & Review
Your surgeon reviews the ultrasound scan to confirm whether cataract surgery or vitrectomy can safely proceed.
- Discuss surgical date with surgeon
- Proceed with pre-op medication if cleared
Pre-Procedure Preparation
- •No fasting required; eat and drink normally before your ultrasound appointment.
- •Remove eye makeup, mascara, and contact lenses before the scan.
- •Inform the technician if you have had recent eye trauma or an open wound on the eye.
- •Bring all previous surgical records and referral notes.
- •Take your routine blood pressure and diabetic medications as usual.
Post-Procedure Guidelines
- •Gently wash any residual gel off your eyelids with clean warm water at home.
- •Do not rub your eye if topical anesthetic drops were used during direct corneal contact.
- •Keep your ultrasound printouts safe in your hospital file for the operating surgeon.
- •No physical restrictions apply following an ophthalmic B-scan.

“I suffered an eye injury from a flying stone on a construction site. My eye was full of blood and I couldn't see anything. Dr. Kaushick performed a B-Scan at Ashvini Netralaya within 15 minutes, found my retina was safe, and guided my treatment. My vision is fully restored today.”
