Ocular ultrasound is a test that is performed to observe in detail the interior of the eyeball and examine the orbit and the tissues that make up the same.
The procedure is simple and takes only a few minutes. It is a diagnostic test that is usually performed people with cataracts o retinal detachment.
En Área Oftalmológica Avanzada We explain below what an eye ultrasound is and how it is performed.
What is an ocular ultrasound?
Ocular ultrasound is a diagnostic test that is performed with high-frequency ultrasound.
Through ocular ultrasound, the ophthalmologist can obtain images of the interior of the eye, even in an eye with opacified structures.
Through an ultrasound of the eye, the parameters of the structures and tissues that are found around the entire eyeball can be visualized.
All the parts of the eye that can be examined through ultrasound can only be analyzed in imaging tests, such as CT or MRI.
Types of eye ultrasound
There are different types of orbital ultrasound and each one studies different structures of the eye.
Ultrasound A
It is also known by the name of one-dimensional ultrasound.
This type of ocular ultrasound is used to measure the size of the different parts of the eye and calculate the power that the intraocular lens and the type of intraocular lens that will be placed in a cataract surgery.
Ultrasound B
B, or two-dimensional, ultrasound allows the ophthalmologist to obtain images of the inside of the eye and the orbit.
This type of eye ultrasound is used to assess the cloudiness of eye structures such as the cornea, crystalline en Cataracts advanced and eye hemorrhages.
Additionally, two-dimensional ultrasound also examines the interior texture of ocular tumors so that the doctor can make a more accurate diagnosis.
UBM
La high resolution ultrasound It is performed to obtain images of the anterior part of the eyeball through high-frequency ultrasound.
This test provides the doctor with high-resolution images to diagnose conditions such as glaucoma, traumatisms and ocular tumors.
High-resolution ultrasound is also performed to calculate the power of the lens in the refractive surgery with intraocular lens.
How is an ocular ultrasound done?
Orbital ultrasound is a fairly simple, painless and non-invasive test.
To perform the exam, the ophthalmologist applies a conductive gel on the ocular ultrasound probe and then proceeds to rub it on the patient's closed eyes.
While the doctor examines with the ultrasound, he may ask the patient to look at different parts while keeping their eyes closed.
The images of the explored structures are seen clearly on a monitor that is connected to the ultrasound probe.
Therefore, the test results are immediate.
When is an ocular ultrasound necessary?
Orbital ocular ultrasound makes it possible to evaluate many structures of the eye, determine their parameters, and examine the anterior tissues of the eyeball.
An ophthalmologist may order this test to:
- Determine the power of an intraocular lens before cataract surgery or refractive surgery with an intraocular lens.
- Examine the inner and anterior part of the eye to measure the opacity of ocular structures in people with cataracts.
- To diagnose glaucoma, retinal detachment, hemorrhages, eye tumors and trauma.
