Diagnosis involves a combination of patient history, visual examination, and advanced imaging techniques:
Ultrasound biomicroscopy: To visualize tumors in the iris and ciliary body.
Fundus photography and fluorescein angiography: To assess the choroid.
Optical coherence tomography (OCT): For detailed imaging of the retina and choroid.
Biopsy: Rarely performed but can be necessary to confirm diagnosis and plan treatment.
