Twenty-one intraocular lesions associated with various systemic diseases in 15 patients were studied by MR imaging. The disorders included diabetes mellitus, cardiovascular disease, Behçet disease, sarcoidosis, and ankylosing spondylitis. MR was performed on a 0.5-T system using a surface-coil technique. Ophthalmoscopic visualization of the fundus was precluded by the presence of opaque media in all cases. MR was found to be effective in demonstrating intraocular bleeding, vitreous opacity, detached lesions of the posterior pole, and eyeball deformity. Surface-coil MR is a useful adjunct in the evaluation of the eyes affected by systemic diseases, especially in patients with opaque media.
Four patients with orbital blowout fractures were evaluated by surface coil MR imaging, and the resulting images were compared with computer reformatted CT scans. The surface coil afforded significant improvement in spatial resolution, resulting in better demonstration of the blowout fracture. Surface coil MR was found superior to CT in the assessment of fracture site, extent of prolapsed orbital fat, and muscle entrapment.
