Abstract:
Objective To evaluate the value of three-dimensional(3D) ultrasonic examination in diagnosis of choroidal melanoma. Methods Twenty eyes(20 cases) proved as choroidal melanoma pathologically were reviewed retrospectively with their 3D ultrasonic examinations(OTI, Canada) preoperatively. Rotating-cut method in static stage was used to observe and measure the tumor. Results In 3D ultrasonic examination, 18 cases were diagnosed as choroidal melanoma according to tumor shape, choroidal depression, retinal detachment, CTH color change and cavernous phenomena of choroidal melanoma. The consistent rate of 3D ultrasonic examination and pathology was 90%. Conclusions 3D ultrasonic examination was valuable for diagnosis of choroidal melanoma, especially in observing and measuring the tumor.
