The buckle is an encircling element. the anterior posterior view shows a cross section above and below on the screen. Rotation vertically demonstrates a superior and inferior cross-section of a highly elevated scleral buckle. There is movement of the separated formed vitreous and far anterior (visible at the left of the screen). Optic nerve shadow is visible as the nerve moves vertically.

Condition/keywords: B scan ultrasound, scleral buckle, video

Video of the fundus of the left eye of a 14-year-old asymptomatic female, where a prepapillary vitreous opacity is observed. The opacity is attached to the origin of the retinal vessels in the optic nerve head, and is considered to be a remnant of the hyaloidal artery.

Photographer: Gerardo Garcia-Aguirre, MD

Condition/keywords: persistence of the hyaloid artery

The vitreous is attached and demonstrates after-movements of formed vitreous as the patient is asked to look to the right and left. There is mild reflectivity in the formed vitreous from collagen. The optic nerve is visible in the superior aspect of the image and the lateral rectus muscle is seen inferiorly.

Condition/keywords: floaters, video, vitreous

In asteroid hyalosis, accumulations of calcium soaps dispersed throughout the vitreous produce bright echoes in the usually echolucent vitreous. The appearance of asteroid hyalosis should not be confused with that of vitreous hemorrhage or vitritis. Many of the larger aggregates in asteroid hyalosis are easily seen as the gain is reduced to below 60 db, unlike vitreous hemorrhage or vitritis which usually disappears at low gain settings. There is also an area of clear echolucent vitreous between the posterior hyaloid face and the asteroid particles, which is usually not present in vitreous hemorrhage or vitritis.

In this ultrasound movie there is little movement of the vitreous. Observe the operculated, small, relatively strongly reflective tissue on the detached, mildly reflective, vitreous back surface (yellow arrow). There is a sagital view of the superior aspect of the lateral rectus muscle (orange arrow). Operculated tear at 10 o'clock position.

Condition/keywords: operculated tear, ultrasound, video, vitreous

Observe orbital cystic structures temporal to optic nerve. Orbital cyst transmits sounds easily. Small optic nerve shadow is visible superior to the cyst in the upper portion of the screen. Strong reflections from choroidal region are consistent with calcification. Tilting of the probe vertically demonstrates communication of the orbital cyst to the vitreous cavity as well as posiible communication to optic nerve.
