KR is a 25 year old white female who presented with a one month history of floaters OD. Past ocular and systemic history were unremarkable. On clinical examination, the visual acuity was 20/20 OU, and the anterior segments were normal. There was a very mild degree of vitreous cell OD, though no cystoid macular edema nor vasculitis. A lobulated white mass was noted overlying the vitreous base inferotemporally OD (thickness 3.3mm). There was no calcification, though prominent cysts were noted on the surface of the lesion. A fluorescein angiogram, echogram, and CT scan were obtained, along with a thorough systemic evaluation.

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.

Another movie from Dr. Yale Fisher and the OphthalmicEdge.org Contact B-scan ultrasonography can be of great help in diagnosing buried drusen of the optic nerve head. When drusen are buried deep in the nerve and invisible to white light, ultrasound has proved to be diagnostically helpful. Drusen of the nerve head are excellent reflectors of sound (probably due to the presence of calcification). Drusen themselves have an extensive shadowing effect, but since we are already shooting through the optic nerve shadow, much of this effect is not evident. They stand out like small pebbles on the head of the optic nerve and their characteristic hyper-reflective signal persist at the lowest decibel levels of gain. Also in this eye, scattered vitreous opacities of very low reflectivity are visible, which may be related to advancing age. In younger eyes, the clear vitreous body generally produces no echoes.
