Título

ULTRASOUND AND DOPPLER IN VITREOUS PATHOLOGY

Introdução e objetivo(s)

To elucidate and differentiate potential diagnostic scenarios associated with vitreous body pathology. To present the indicators that facilitate a distinctive diagnosis using ultrasound and Doppler imaging.

Método(s)

The appropriate ultrasound technique is detailed, emphasizing the use of a high-frequency linear transducer. Additionally, the application of color and pulsed Doppler is recommended to assess vascularization, and a list of differential diagnoses is provided, including vitreous hemorrhage, vitreous degeneration, synchysis scintillans, asteroid hyalosis, posterior vitreous detachment, and vitritis.

Discussão

The vitreous body or vitreous humor is a transparent, avascular gel that occupies ~80% of the globe and helps to maintain the position of the retina and the shape of the globe. The various conditions can range from asymptomatic patients to losses in the visual field.
The discussion focuses on the anatomy and functions of vitreous humor, as well as the diversity of associated pathologies, their clinical manifestations, and the importance of ultrasound and Doppler in their study. The utility of these methods in situations of anterior segment opacity that hinders direct ophthalmic examination is explored. The discussion is oriented towards the interpretation of specific signs and differential diagnoses, highlighting how the proper technique can provide valuable information in malformations and tumors.

Conclusões

In conclusion, when there is a clinical suspicion of vitreous humor pathology, the significant contribution of ultrasound and Doppler in diagnosis and monitoring is emphasized. Careful technique, using specific transducers and applying Doppler, allows for addressing differential diagnoses. These non-invasive and accessible methods position themselves as essential tools in the study of ophthalmic conditions related to the vitreous body.
