non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...

purpose: to design and manufacture iodine 125 radioactive plaques which can be used in patients with ocular melanoma, and to evaluate the efficacy of plaques in an animal model. methods: this prospective basic study was performed in collaboration with farabi hospital and tehran atomic energy agency. the iodide 125 plaques were designed and manufactured based on the collaborative ocular melanoma...

Choroidal melanoma is one of the most malignant tumors organ vision, development which associated with risk metastasis and possibility death, indicates relevance search application effective methods treatment this pathology. To date, in choroidal melanoma, preference given to organ-preserving aimed at achieving local control over tumor. One promising techniques photodynamic therapy, a method ba...

BACKGROUND Indocyanine green video-angiography is a recently popularised technique for imaging the retina and choroid. Little is known about the value of this technique in the evaluation of choroidal tumours. METHODS Indocyanine green video-angiograms of 51 patients with choroidal tumours, including 32 with choroidal melanoma, five with choroidal naevus, four with choroidal metastasis, four w...

BACKGROUND AND PURPOSE The aim of this study was to establish the MR imaging characteristics of choroidal hemangioma and to compare them with those of uveal melanoma. METHODS Among 41 patients examined at 1.5 T (4-cm surface coil, T1-weighted and fast spin-echo T2-weighted sequences), 25 had uveal melanoma and 16 had circumscribed choroidal hemangioma. After i.v. bolus injection of gadopentet...

AIM To report the evolution of a de novo choroidal melanoma. METHOD This is a case report of a 22-year-old white male patient who has been undergoing periodic examination for a choroidal 'freckle' since 10 years of age. RESULTS In 2007, a fundus photograph of the left eye showed a nondescript area of choroidal hyperpigmentation temporal to the fovea. Progressive growth was observed and, by ...

AIMS To investigate whether corneal autofluorescence is different in patients with choroidal melanoma or choroidal naevus. METHODS Corneal autofluorescence was determined by fluorophotometry in both eyes of 32 patients with a unilateral choroidal melanoma, 32 patients with a unilateral choroidal naevus, and 32 age matched healthy controls. The corneal autofluorescence ratio between affected a...

Synopsis In optical coherence tomography angiography, the choroidal vascular flow rate in choroidal melanoma is significantly lower than that in choroidal nevus. Objective The 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. Methods...

Choroidal melanoma primarily metastasizes to the liver. Isolated extrahepatic metastases have rarely been reported and they generally resulted in death within 6 months. We describe a patient who developed an isolated brain metastasis 27 years after his left eye was enucleated for choroidal melanoma. The metastasis was successfully treated with surgery and radiotherapy. The patient is alive and ...
