This is a partial vitreous separation that demonstrates a mildly reflective curvilinear shape of the partially separated vitreous face. The vitreous is attached inferonasally and inferotemporally, but detached and freely mobile at 6 o'clock.

VA 20/20. In asteroid hyalosis, there is a space between the posterior hyaloid face and the calcified asteriod lesions. Use gain to differentiate between VH and asteroid hyalosis (asteroid still present when gain is decreased).

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.

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.

Using a chandelier endoillumination, a 2-handed approach with forceps and a vitrector can be used to remove preretinal membranes in a TRD from PDR. The subretinal fluid had a high viscosity. It was removed mechanically by rotating the vitrector.

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.

This is a dislocated lens. You can see a large ovoid object resting against the ocular wall shadowing the orbital fat. Internal reflectivity demonstrates a nucleus within the larger ovoid structure. Moderate reflections from the subcapsular space and nuclear area are visible, conistent with hypermature cataract (Morgagnian type structure).

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.

Infusion cannula positions can be visualized with the endoscope, especially useful when microscopic views are limited or impossible as in this short movie. Here, the infusion cannula had been placed in a standard fashion but endoscopic imaging reveals partial engagement of peripheral retinal tissue. Manipulation of the tip under endoscopic viewing eliminates the undesired engagement and reveals the proper infusion position with no obstruction.

Endoscopically controlled surgical repair of a rhegmatogenous retinal detachment in a phakic glaucoma patient with a fixed miotic pupil. The formed vitreous is still attached in the posterior pole but separated peripherally. A horseshoe tear is located in the superior nasal portion of the globe. The flap is trimmed and the posterior formed vitreous face is removed from the optic nerve and posterior pole with an open vertical scissors blade. An air fluid exchange through the break completes the reattachment.
