PURPOSE To correlate the histopathological diagnoses established by diagnostic vitrectomy and chorioretinal biopsy in patients with clinically suspected primary intraocular lymphoma (PIOL) or chronic idiopathic uveitis, and the clinical follow-up data. METHODS Eighty-four consecutive pars plana vitrectomy (PPV) specimens, three chorioretinal biopsies and(More)
Uveal melanoma is the most common intraocular malignancy. About 50% of patients die of metastases, which almost exclusively originate from primary tumors that have lost one chromosome 3 (monosomy 3). To gain insight into the biological mechanisms that underlie the various metastasizing potential of uveal melanoma, we have determined gene expression levels(More)
There are few epidemiologic studies dealing with electromagnetic radiation and uveal melanoma. The majority of these studies are exploratory and are based on job and industry titles only. We conducted a hospital-based and population-based case-control study of uveal melanoma and occupational exposures to different sources of electromagnetic radiation,(More)
Malignant uveal melanoma is the commonest primary intraocular tumour in adults. It metastasizes frequently and 50% of patients die within 10 years of diagnosis. The expression of cyclin D1, p53, and MDM2 in uveal melanoma and their relationship to metastasis-free 5-year survival was determined, in order to investigate whether these proteins help to(More)
PURPOSE Primary intraocular lymphoma (PIOL) is an uncommon non-Hodgkin lymphoma and is usually of B-cell type. Intraocular T-cell or T/NK-cell lymphomas are extremely rare and mostly represent a secondary manifestation of either a cutaneous or a systemic lymphoma. The aim of the current paper is to report the clinical, histopathological and molecular(More)
OBJECTIVE Lymphomas of the eye and its adnexa are frequently of B lineage. This study aims to characterize the clinical and histopathologic features of the rare non-B-cell non-Hodgkin lymphomas (NHL) of these locations. DESIGN Retrospective, noncomparative case series. PARTICIPANTS Seven cases of T- and T/NK-cell lymphomas involving the ocular and(More)
AIM To investigate the safety and efficacy of beta ray brachytherapy in treatment of vasoproliferative tumours of the retina (VTR). METHODS 35 consecutive patients with symptomatic VTR were treated with a ruthenium-106 ((106)Ru) plaque. Three tumours had been treated previously (two with cryotherapy; one with transpupillary thermotherapy). 32 VTR (91.4%)(More)
Uveal melanoma is the most common form of primary eye cancer. Monosomy 3, which is an unusual finding in tumors but is present in approximately 50% of uveal melanomas, is significantly correlated with metastatic disease. To obtain positional information on putative tumor suppressor genes on this chromosome, we have investigated tumors from 333 patients by(More)
AIM To investigate the safety and efficacy of photodynamic therapy with verteporfin in patients with choroidal haemangioma. METHODS A non-randomised, prospective clinical investigation of 19 patients with symptomatic circumscribed choroidal haemangioma was performed. Unsuccessful pretreatment (external beam irradiation, laser photocoagulation) was(More)
Some types of cancer have been associated with abnormal DNA fingerprinting. We used random amplified polymorphic DNA (RAPD) to generate fingerprints that detect genomic alterations in human breast cancer. Primers were designed by choosing sequences involved in the development of DNA mutations. Seventeen primers in 44 different combinations were used to(More)
