• Computed tomographic (CT) scans were obtained from 48 patients with posterior uveal melanoma. The CT measurements of maximal and minimal basal diameters and thickness of each tumor were compared with the assessments of these tumor dimensions obtained by ophthalmoscopic estimation (basal diameters only) and standardized A-scan ultrasonography (thickness only) and with the gross pathologic measurements of these tumors. The correlation between measurements of tumor thickness by CT scanning, standardized A-scan ultrasonography, and gross pathologic analysis was substantially better than that between the CT, ophthalmoscopic, and gross pathologic measurements of tumor basal diameters. Computed tomographic scanning appears to be a good method for determining the in vivo size of choroidal and ciliary body melanomas.
