A 54 year-old woman
presented with a one-year history of poor right vision. Examination revealed
the presence of dense cataract and dilated episcleral vessels near the nasal
limbus. Ultrasound scan revealed a large lesion in anterior part of the
posterior segment. The appearance suggested that the dilated episcleral
vessels are sentinel vessels. She was referred to the medical team for the
detection of any primary neoplasm but the team did not reveal any medical
condition of note. At the subsequent ophthalmic consultation, the base of
the iris showed the presence of multiple black lesions with dilated iris
vessels. The features were suggestive of a choroidal melanoma with anterior
chamber extension. The patient was informed of the possible diagnosis and
enucleation was proposed.
