Ultrasonic evaluation of the vitreous and retina.

Ultrasonic evaluation of the vitreous body augments and complements visual and clinical assessment in any condition in which some form of media opacity exists, eg, cornea, lens, hemorrhage, or subretinal mass. The appearance of the eye in hypotony, the presence of foreign material, the pattern of hemorrhage, and the presence of a detached retina or choroid are all identifiable and their diagnosis may be of critical importance to patient management. Patterns of diabetic retinopathy and ocular tumors are usually characteristic using conventional 10 MHz ultrasound. The use of Very High Frequency (VHF or UBM) ultrasound can identify ciliary body detachment or other retroiridal pathology, such as tumors and cysts.

Ophthalmic, ultrasonographic findings in primary central nervous system lymphoma with ocular involvement.

PURPOSE: To describe and classify ophthalmic, ultrasonographic findings in patients with primary central nervous system lymphoma with ocular involvement. METHODS: B- and A-scan ultrasonography was performed on the eyes of 13 patients with primary central nervous system lymphoma with ocular involvement. RESULTS: In seven patients, the eyes were the site of initial involvement. In the other six patients, both ocular and central nervous system disease were present at the initial evaluation. All patients had abnormal ultrasonographic findings. The most common were vitreous debris (n = 10), choroidal-scleral thickening (n = 6), and widening of the optic nerve (n = 4). Elevated chorioretinal lesions (n = 3) and retinal detachment (n = 2) were also found. CONCLUSION: Ophthalmic ultrasonography is a useful adjunctive diagnostic technique for characterizing ocular involvement in lymphoma. Ocular lymphoma may present as chorioretinitis, vitreitis and nonspecific uveitis; it produces characteristic, but nonspecific findings on ultrasonography. The diagnosis of ocular involvement is an important factor in determining treatment.
