Approach to the patient in the diagnosis of Choroidal Malignant Melanoma, Question – Answer with Kaan Gündüz

The most valuable diagnostic method in intraocular tumors is indirect ophthalmoscopy. USG is very important in determining the thickness of the lesion and documenting post-treatment changes. However, in today's conditions, we have important auxiliary examination opportunities. OCT is especially important in detecting macular edema and fluid. In choroidal melanomas, thickening and edema of the macula may be observed before treatment due to increased VEGF levels in the eye. OCT is important in detecting such changes. Since FAF shows the amount of lipofuscin in the lesion, it reveals the activity of the lesion. Hyperotofluorescence of> 50% of the lesion surface, in other words, the diffuse pattern is a risk factor for growth and metastasis. On fluorescein angiography, choroidal melanoma shows focal hyperfluorescence starting from the late venous phase and gradually increasing.
