Learning objectives
To review the indications and contraindications of ocular ultrasonography and the items to be valued.
To describe the steps that a radiologist might performance in an ocular ultrasound study to get the most relevant information.
To tie in the main anatomic and vascular structures in the ocular globe with the items to be valued in ocular ultrasound performances looking forward to guiding the differentialdiagnosis.
To analyzesome of the most common ocular pathologies that could be easily differentiated by thoroughocular ultrasound performances assessingthe aforementioned steps and...
Background
Ocular ultrasonography is one of the less frequently diagnostic procedures in the radiology departments day-to-day work.
This might be secondary to the fact that ophthalmic pathologies are usually assessed by ophthalmoscopy performed by ophthalmologists.
Radiologists must know when the ocular ultrasound provides useful information beyond the ophthalmoscopy.
Nevertheless,
ocular ultrasonography is heavily operator dependent for accurate evaluation,
which limits its overall utility.
This is whyit is prior to having in mind what information could be potentiallyassessed by different ultrasound modes and how to properly get...
Findings and procedure details
First step:complete examination and measurements
Radiologists must know how the healthy eye is visualized in an ocular ultrasound performance due to checking if there is any abnormality:
Anterior segment: most anterior echogenic structure are the soft tissues of the eyelid,
immediately posterior there is a curved,
thin,
echogenic band corresponding to the cornea.
The next echogenic and thin band is the anterior capsule of the lens,
and on each side of it,
the echogenic lines are the iris and ciliary bodies.The anechoic space between the...
Conclusion
Moreover than just visualizing the ocular globe and its pathology when any condition avoids an adequateophtalmoscopy study,
radiologists can meaningfully contribute to the diagnostic process of a wide range of ocular pathologiesperforming some quick,
simple and affordable steps in ocular ultrasonography studies.
Radiologists should be able toperform ocular ultrasonography studies with the aforementioned steps and interpetthe correspondent findingswith the purpose of accurately guiding the diagnostic assessment or even reaching the final diagnosis.
