Choroidal melanoma: comparison of CT, fundoscopy, and US.
1985
Computed tomography (CT) was compared with fundoscopy and ultrasound (US) in 62 patients with primary choroidal melanoma. All lesions were detected with CT and fundoscopy and all but one with US. Of five cases of extrascleral extension, four were identified with CT and fundoscopy and two with US. CT best depicted the extent of retrobulbar tumor. Tumor thickness was best evaluated with CT, with good correlation between CT and US. Tumor enhancement was noted in all 51 patients who had both noncontrast and contrast CT. Because of its higher density, tumor could be distinguished from retinal detachment on CT scans in most cases.
