Application of Multimodal and Molecular Imaging Techniques in the Detection of Choroidal Melanomas

open access: yesFrontiers in Oncology, 2021
Choroidal melanomas are the most common ocular malignant tumors worldwide. The onset of such tumors is insidious, such that affected patients often have no pain or obvious discomfort during early stages. Notably, enucleation is required for patients with

Small choroidal melanoma and pseudomelanomas: methods of differential diagnostics. Part 1

open access: yesРоссийский офтальмологический журнал, 2019
Choroidal melanoma is a malignant tumor prone to early metastasis. Its clinical picture is polymorphic, as a result of which it can simulate many diseases of the fundus, which are referred to in the literature as pseudomelanomas.
