Ultrasound offers high sensitivity in diagnosing vitreous pathologies in pediatric patients and is increasingly being used as the preferred method for diagnosis since it does not use ionizing radiation.
The vitreous body is a transparent, gelatinous substance found inside the eye cavity and occupies the space between the lens and the retina. It is avascular and its echostructure is anechoic. Its main function is to provide structural stability, giving volume to the eyeball and providing support to the retina.
Different pathologies can affect it, both congenital and acquired. In pediatrics the most common ones are vitreous hemorrhage, vitritis, posterior vitreous detachment, synchysis scintillans and asteroid hyalosis. Clinically, they can present asymptomatically or with various symptoms such as myodesopsias, photopsias and decreased visual acuity, among others.
Ultrasound and Doppler are excellent methods for studying the eyeball, as it is a superficial organ with a liquid component. Furthermore, they are accessible, non-invasive methods that do not require anesthesia and it provide relevant information, especially when opacification of the anterior segment hinders direct ophthalmological examination.
