Objective:

To evaluate the diagnostic value of ultrasonic elastosonography in the differential diagnosis of benignand malignant tumors by comparing the strain ratios of choroidal melanoma

choroidal hemangioma

choroidal metastatic carcinoma and retinoblastoma.

Methods:

A total of 65 cases (67 eyes) of intraocular tumors were selected from June to October 2016 in Eye Center of Beijing Tongren Hospital

Capital Medical University. All eyes were examined by two-dimensional ultrasound

color Doppler ultrasound and ultrasonic elastosonography. The strain ratios of the tumors to surrounding norma

l tissues were calculated. According to the results of clinical diagnosis

the differences in strain ratio between malignant and benign tumors

and among various intraocular malignant tumors were compared. And then the value of ultrasonic elastosonography in the diagnosis of benign and malignant intraocular tumors was analyzed.

Results:

The strain ratios of 65 cases (67 eyes) were measured respectively: 42.2718.88 in choroidal melanoma

14.4012.66 in choroidal hemangioma

50.696.20 in choroidal metastatic carcinoma

and 48.2812.05 in retinoblastoma. The strain ratios of these tumors were analyzed by using variance analysis. There was no significant difference among choroidal melanoma

choroidal metastatic carcinoma and retinoblastoma. However

there were significant differences between the three malignant tumors and choroidal hemangioma.

Conclusion:

There is a significant difference in hardness between intraocular malignant tumors (choroidal melanoma

choroidal metastatic carcinoma and retinoblastoma ) and benign tumors (choroidal hemangioma). Ultrasonic elastosonography can be used as an important examination method for identification of benign and malignant intraocular tumors.
