Objective: To analyze features of retinal and scleral infiltration of uveal melanoma. Methods: It was a retrospective case series study. The pathological and clinical data of 102 cases of uveal melanoma were analyzed retrospectively, which were collected between Jun. 2001 and Apr. 2013 in Beijing Tongren Hospital, Capital Medical University. The tumor shape, size, cell types, retinal and scleral invasion were recorded and analyzed. The relationship between retinal invasion and scleral invasion was analyzed by trend Chi-square test...

PURPOSE: To describe the features of choroidal tumors on infrared (IR) imaging and to determine the diagnostic sensitivity and specificity of intratumoral choroidal vascular loops on IR imaging for circumscribed choroidal hemangioma (CCH). METHODS: Infrared and indocyanine green images of CCH, choroidal metastases, and choroidal melanomas were reviewed. The main outcome measure was the presence of intratumoral choroidal vascular loops and tufts on IR images. The secondary outcome measure was the presence of peritumoral vascular expansion on indocyanine green images...

PURPOSE: To evaluate efficacy and toxicity of two different protocols for eye-conserving treatment of patients with small to intermediate-sized choroidal melanomas; the current ruthenium-106 (Ru106) brachytherapy protocol and the preceding protocol of Ru106-brachytherapy with transpupillary thermotherapy (Ru106/TTT). METHODS AND MATERIALS: Long-term outcomes of 449 consecutive patients, of whom 196 (43.6%) treated using Ru106/TTT and 253 (56.3%) treated using Ru106, were compared in terms of local control, survival, eye preservation and visual outcome...

Particle therapy provides an opportunity to study the human response to space radiation in ground-based facilities. On this basis, a study of light flashes analogous to astronauts' phosphenes reported by patients undergoing ocular proton therapy has been undertaken. The influence of treatment parameters on phosphene generation was investigated for 430 patients treated for a choroidal melanoma at the proton therapy centre of the Institut Curie (ICPO) in Orsay, France, between 2008 and 2011. 60% of them report light flashes, which are predominantly (74%) blue...

INTRODUCTION: Uveal melanoma is the most common primary intraocular tumour in adults in Caucasians and in 75% is arising from choroid. It threatens not only the patients loss of vision and eye, but also 50% of patients after 5-year interval after therapy die due to distant metastases. The treatment of small and medium-sized melanoma are methods preserving eye globe. Almost half of the total number of patients is still unavoidable enucleation. Considerably rarer is indicated exenteration of an orbit...

PURPOSE: To investigate the safety and potential efficacy of ranibizumab for prevention of radiation complications in patients treated with proton irradiation for choroidal melanoma. METHODS: Forty patients with tumors located within 2 disc diameters of the optic nerve and/or macula were enrolled in this open-label study. Participants received ranibizumab 0.5 mg or 1.0 mg at tumor localization and every 2 months thereafter for the study duration of 24 months. The incidence of adverse events, visual acuity, and other measures of ocular morbidity related to radiation complications were assessed...

PURPOSE: To report a case of optic nerve meningocele simulating massive, recurrent extraocular extension of choroidal melanoma. METHOD: Case report. RESULTS: A 53-year-old white man with choroidal melanoma in his left eye of 7.3-mm thickness was treated with plaque radiotherapy and transpupillary thermotherapy. On 1-year follow-up examination, visual acuity was 20/20 in the right eye and 20/30 in the left eye. The regressed choroidal melanoma scar in the left eye measured 1...

AIM: to analyze the association of extrabulbar tumor growth with pathological and molecular genetic changes in patients with uveal melanoma (UM). SUBJECTS AND METHODS: A total of 134 UM patients aged 22 to 84 years were examined and treated. The mean height of the tumor was 9.2±2.9 mm; the diameter of its base was 15.3±3.5 mm. Enucleation of the affected eye was performed in 97.8% of cases. Spindle-cell (n=61 (45.6%)), mixed cell (n=46 (34.3%)), and epithelioid cell (n=27 (20...

AIM: To examine phosphorylation of alphaB-crystallin (p-αBC), a vascular endothelial growth factor (VEGF) chaperone, and immunohistochemically investigate relationship between p-αBC, VEGF and phosphorylated p38-mitogen-activated protein kinase (p-p38 MAPK) in the epiretinal membrane of human proliferative diabetic retinopathy (PDR). METHODS: Eleven epiretinal membranes of PDR surgically excised were included in this study. Two normal retinas were also collected from enucleation tissues due to choroidal melanoma...

PURPOSE: To compare the rates of tumour recurrence following episcleral brachytherapy for uveal melanoma before and after implementation of intraoperative echographic confirmation of plaque placement. MATERIALS AND METHODS: All patients with primary single ciliary body or choroidal melanoma treated with iodine-125 or ruthenium-106 plaque brachytherapy between 1 January 2004 and 30 December 2013 were included. Exclusion criteria were patients with previous radiation treatment and patients who received adjuvant transpupillary thermotherapy...

OBJECTIVES: One day session LINAC based stereotactic radiosurgery (SRS) at LINAC accelerator is a method of "conservative" attitude to treat the intraocular malignant uveal melanoma. METHODS: We used model Clinac 600 C/D Varian (system Aria, planning system Corvus version 6.2 verification IMRT OmniPro) with 6 MeV X by rigid immobilization of the eye to the Leibinger frame. The stereotactic treatment planning after fusion of CT and MRI was optimized according to the critical structures (lens, optic nerve, also lens and optic nerve at the contralateral side, chiasm)...

Uveal melanoma is the most frequent primary intraocular neoplasm in adults. Although malignant melanoma may be located at any point in the uveal tract, the choroid and ciliary body are more frequent locations than the iris. In the present study, we examined ADAM10 expression levels in primary uveal melanoma both with and without metastasis, and we evaluated their association with other high risk characteristics for metastasis in order to assess if ADAM10 can be used to predict metastasis. This study included a total of 52 patients, 23 men and 29 women, with uveal melanoma...

BACKGROUND: To illustrate the evolution of paraneoplastic vitelliform maculopathy over one year using optical coherence tomography. METHODS: Observational case report. RESULTS: A 65-year-old man with a history of ocular melanocytosis and choroidal melanoma of the left eye treated with plaque brachytherapy 3 years prior returned for his yearly follow-up visit. The visual acuity in the right eye was 20/20. Subtle thickening of the interdigitation zone layer was noted on optical coherence tomography...

BACKGROUND: To establish a mouse model with the aim of studying the tumour biology and metastasis formation of uveal melanoma. METHODS: Two human primary uveal melanoma cell lines (UMT2 and UMT42) were injected into the choroid of BALB/c nude mouse eyes. Intraocular tumour growth and metastasis formation in the liver and lungs were assessed after 13 to 22 weeks. Formalin-fixed, paraffin-embedded material was processed via haematoxylin and eosin staining for histological examination and periodic acid Schiff staining to search for extravascular matrix patterns...
