Significant advancements have been made in the last decades in the treatment of uveal melanoma. Radiation therapy can achieve, depending on the method, local tumour control in up to 98% of cases. Surgical modalities have been implemented in the ocular therapy for uveal melanoma either to treat/prevent radiation complications, such as so-called toxic tumour syndrome, or to primarily treat the tumour with or without adjunctive radiotherapy. These include endoresection and transscleral resection for melanomas of the choroid/ciliary body or irido-trabeculo-cyclectomy for melanomas of the iris-ciliary body...

Purpose: The most common malignant intraocular tumors with a high mortality in adults are uveal melanomas. Uveal melanomas arise most frequently in the choroid or ciliary body (97%) and rarely in the iris (3%). Whereas conjunctival and posterior uveal (ciliary body and choroidal) melanomas have been studied in more detail genetically, little data exist regarding iris melanomas. Methods: In our study, we genetically analyzed 19 iris melanomas, 8 ciliary body melanomas, 3 ring melanomas, and 4 iris nevi...

Long-term results with linear accelerator LINAC-based stereotactic radiosurgery for intraocular uveal malignant melanoma were assessed. A retrospective study was carried out of patients with uveal melanoma after a 1-day session stereotactic radiosurgery at LINAC in Slovakia. In the period 2001-2015, a group of 150 patients with uveal melanoma (139 choroidal melanoma, 11 ciliary body melanoma) was treated. The median tumor volume at baseline was 0.5 cm (with range from 0.2 to 1.6 cm). Tumors ranged in size from 2...

We report a rare case with histologically proven melanocytoma of the iris that demonstrated diffuse melanocytic proliferation with uncontrolled secondary glaucoma and investigate the etiology of the intraocular pressure elevation. The patient was a 78-year-old man with a history of darkened iris of his left eye. The intraocular pressure was 39 mm Hg. A slit-lamp examination showed a diffuse darkened iris, and a gonioscopic examination revealed open angle with circumferential heavy pigmentation. There was no pigment dispersion of the anterior chamber and no pigment deposition of the cornea...

A 40-year-old male presented to the ophthalmology clinic with a darkly pigmented infratemporal lesion in his right eye. The corrected visual acuity in both eyes was 6/6 and both pupils were equal and reactive. Slit lamp biomicroscopy showed a well-demarcated and heavily pigmented lesion in the peripheral iris between 6 and 8 o'clock. Ultrasound biomicroscopy (UBM) revealed a solid mass deriving from the iris stroma without ciliary body involvement, helping to classify the uveal melanoma and establishing the diagnosis of iris melanoma...

Importance: Uveal melanoma (UM) is an intraocular primary malignant neoplasm that often gives rise to metastatic disease for which there are no effective therapies. A substantial proportion of UMs express the cancer-testis antigen PRAME (preferentially expressed antigen in melanoma), which can potentially be targeted by adoptive T-cell therapy. Objective: To determine whether there may be a rationale for PRAME-directed T-cell therapy for metastatic UM. Design, Setting, and Participants: An experimental study using a retrospective cohort of 64 patients with UM (median follow-up, 62 months) was conducted from January 8, 2015, to November 20, 2016, at the Leiden University Medical Center...

PURPOSE: To evaluate clinico-pathological and molecular prognostic factors in a well-defined series of posterior uveal melanoma (UM) with focus on chromosomal aberrations and mutations in the GNAQ, GNA11 and BRCA1-associated protein 1 (BAP1) genes. METHODS: Formalin-fixed paraffin-embedded (FFPE) tissue samples were obtained from 50 consecutive eyes enucleated for UM between 1993 and 2005. The material was tested for loss of chromosome 3 and gain of chromosome 8q gene signatures by selective molecular gene markers using multiplex ligation-dependent probe amplification (MLPA), and for DNA mutations in the GNAQ, GNA11 and BAP1 genes...

Approximately 90% of uveal melanoma develop in the choroid, with the remainder arising in the ciliary body or the iris. The treatment of uveal melanoma is aimed at conserving the eye and useful vision, and, if possible, preventing metastatic disease. Enucleation is now reserved for tumors that are large and/or involve the optic disc, having largely been replaced by various forms of radiotherapy (plaque brachy-therapy, proton beam or stereotactic radiotherapy) and laser therapy. Whereas iridectomy and iridocyclectomy are widely performed, transscleral exoresection of choroidal tumors is performed only in a few centers because it requires special skills and hypotensive anesthesia...

Angiotropism is a marker of extravascular migration of melanoma cells along vascular and other structures and a prognostic factor in cutaneous melanoma. Because of this biological and prognostic importance in cutaneous melanoma, angiotropism was studied in uveal melanoma (UM). This retrospective study performed at a single ocular oncology referral center included 89 patients from the study period 2006-2008. All patients were diagnosed with UM from the choroid and/or ciliary body. All patients underwent enucleation for prognostic purposes and definitive therapy...

Uveal melanoma (UM) is the most common intraocular malignancy and arises from melanocytes in the iris, ciliary body, or choroid. Early diagnosis and local treatment is crucial, as survival correlates with primary tumor size. However, approximately 50% of patients will develop metastatic disease with 6-12 months' survival from metastatic diagnosis. Genomic analyses have led to the development of gene-expression profiles that effectively predict metastatic progression; unfortunately, no adjuvant therapy has been shown to prolong survival to date...
