Abstract:
Objective:To investigate the ultrasonic features, contrast-enhanced ultrasound findings and long-term follow-up results of melanocytoma of the optic disc(MCOD).Methods:The data of 35 patients (35 eyes, 35 lesions) diagnosed with MCOD in Beijing Tongren Ophthalmic Center, Beijing Tongren Hospital from September 2012 to October 2020 were retrospectively analyzed. The B-mode ultrasonography and color Doppler flow imaging (CDFI) were performed on them. The size, morphology, internal echo and secondary changes of the lesions were analyzed. Contrast-enhanced ultrasound was performed on 13 patients. At the same time, 9 patients were followed up for long-term observation.Results:Six lesions (17.1%) showed hemispherical high echo, and 29 lesions (82.9%) showed limited uplift high echo. The largest base diameter of the lesions was (4.0±0.8)mm, average height was(1.9±0.4)mm. Internal echo characteristics: 8 lesions (22.9%) showed uniform echo and 27 lesions (77.1%) showed uneven echo.Lesion boundary: 35 lesions (100%) showed clear lesion boundary. Fifheen lesions (42.9%) showed secondary vitreous opacity. CDFI: blood flow signals could be detected inside the lesions in 19 lesions(54.3%), and not in 16 lesions(45.7%). Contrast-enhanced ultrasound showed 11 of the 13 lesions (84.6%) were completely filled with contrast agent.Conclusions:MCOD has certain ultrasonographic characteristics, which can provide a reliable basis for clinical diagnosis and differential diagnosis. There is no significant change in tumor size after long-term follow-up.
