An occular ultrasound is a safe, quick, and painless test that uses sound waves to create detailed images of the inside of your eye. It’s often used when doctors need to check for problems with the eye that they can’t easily see with a standard eye exam. Ocular ultrasound is especially helpful in situations where the eye might be swollen, injured, or if vision is blocked due to conditions like cataracts or bleeding inside the eye. This test helps detect eye issues early, which is important for preserving vision and overall eye health.
What is an Ocular Ultrasound?
An occular ultrasound works by sending sound waves into the eye through a small device called a transducer, which is placed gently over your eyelid. These sound waves bounce back, creating a picture of the inside of your eye on a screen. This allows doctors to see structures like the retina, optic nerve, and eye muscles clearly, even if the front of the eye is cloudy or blocked.
There are two types of ocular ultrasounds:
- A-scan
This type measures the length of the eye and is often used before cataract surgery.
- B-scan
This provides a two-dimensional image of the structures inside the eye and is more commonly used to check for problems in the eye.
Health Benefits of Occular Ultrasound
There are several important health benefits to performing an occular ultrasound:
- Detecting Eye Injuries
If you’ve had an eye injury or trauma, an occular ultrasound can help doctors see if there is any internal damage, such as a detached retina or bleeding. This is crucial for treating the injury early and preventing long-term vision loss.
- Diagnosing Eye Conditions
The test is helpful in detecting conditions like retinal detachment, tumors, bleeding inside the eye, or foreign objects. Even if the front of the eye is cloudy due to cataracts or other issues, the ultrasound can still give a clear view of the structures in the back of the eye.
- Monitoring Eye Diseases
Occular ultrasound is useful for monitoring conditions like glaucoma, where the pressure inside the eye increases and can damage the optic nerve. It can also help track the progression of tumors in or around the eye.
- Pre-Surgery Planning
Before certain eye surgeries, such as cataract surgery, an A-scan ultrasound helps measure the length of the eye. This information helps doctors choose the right lens implant for the surgery, ensuring better vision after the procedure.
When is Ocular Ultrasound Needed?
Doctors may recommend an occular ultrasound if:
- You have had an eye injury or trauma.
- You have conditions like cataracts that make it hard to see the back of your eye during a normal eye exam.
- You’re experiencing unexplained vision loss or changes in vision.
- You have symptoms of retinal detachment, such as flashes of light or sudden vision loss.
- You need eye surgery, such as cataract surgery, and measurements are required.
An occular ultrasound is a valuable tool for diagnosing and monitoring a wide range of eye problems. It’s a non-invasive and Sonobee recommend using ocular ultrasound because it’s a safe test that helps doctors see inside the eye clearly, even when the view is blocked by conditions like cataracts or swelling. By catching eye issues early with an ocular ultrasound, doctors can take steps to protect your vision and ensure your eyes stay healthy.
