Optical coherence tomography angiography in choroidal melanoma and nevus

Abstract: SynopsisIn optical coherence tomography angiography, the choroidal vascular flow rate in choroidal melanoma is significantly lower than that in choroidal nevus.ObjectiveThe objective of this study was to describe the choriocapillaris and retinal features imaged by optical coherence tomography angiography (OCTA) in eyes with choroidal nevus from small malignant choroidal melanoma.MethodsIn this retrospective, noninvasive, observational study, 11 patients diagnosed with small choroidal mass (five with choroidal … Show more

“…The SMV measurement was conducted on the choroidal capillary layer overlying the choroidal mass that was diminished compared with the corresponding surface to the fellow eye in cases of choroidal melanoma, and was intact in nevi. Peripheral feeding vessels were also more prominent in malignant lesions [ 25 ].…”

“…Вышеуказанные факты диктуют необходимость более глубокого исследования невуса и меланомы хориоидеи для дифференциальной диагностики и выявления уже на ранних стадиях признаков трансформации невуса в меланому хориоидеи. К методам диагностики начальной меланомы и невуса хориоидеи относят офтальмоскопию, УЗИ, ФАГ, СОКТ, ОКТ-А [1][2][3][9][10][11][12][13][14][15][16][17][18][19].…”

“…Основным патогномоничным признаком, отличающим начальную меланому от невуса хориоидеи, является наличие сосудов опухоли. ОКТА позволяет неинвазивно дифференцировать сосудистую сеть в ткани опухоли [14][15][16][17][18][19]. Существующие литературные источники указывают, что для МХ характерно наличие изооптических или гипоотражающих структур, тогда как для невуса хориоидеи -гетерогенность и гиперрефлективность сосудистой сети.…”
