The authors present a series of 13 patients with intraocular melanomas imaged using high resolution Small Parts Ultrasonography. All patients underwent enucleation and subsequent histopathologic examination. On ultrasonography, patients were assessed for the presence of retinal detachment, choroidal excavation, rupture through Bruch’s membrane, retro-orbital fat shadowing, and acoustic texture. Correlation with histopathology demonstrated that using traditional criteria, the majority of rupture through Bruch’s membrane was missed due to the limits of instrument resolution. No patients with a homogeneous acoustic texture showed evidence of tumour necrosis or haemorrhage, while the vast majority of those with an inhomogeneous texture did. The authors suggest that high resolution small parts scanning may result in an alteration in the traditionally accepted criteria for the B-Scan diagnosis of choroidal melanoma. |
