Purpose: To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods: Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body...

The author presents a retrospective case report of a 54-year-old male with ipilimumab (Yervoy; Bristol-Myers Squibb, New York City, NY)-induced Vogt-Koyanagi-Harada Disease (VKH), which consisted of uveitis, optic neuritis, and choroiditis that was successfully treated with oral dexamethasone. The patient demonstrated resolution of uveitis, optic neuritis, and choroiditis 1 month following initiation of oral dexamethasone. Ipilimumab is a recently approved therapy for malignant melanoma. Reports have identified that VKH disease is a potential side effect of the medication...

Choroidal melanoma (CM), the most common intraocular tumor in adults, is still a rarity in Asia. Having a high propensity for metastasis with a poor survival, recognizing it early is essential. Although it has typical clinical features, there are instances of simulating lesions. Fine-needle aspiration biopsy can be a valuable tool not only to confirm our clinical suspicion but also aid in prognosticating it. From days of histopathological prognostic markers, we are moving on to genetic markers which are reliably providing insights, helping us in providing a better care for our patients...

Ocular or choroidal nevus (CN) is a rare benign neoplastic lesion of the eye. The cause of CN onset/progression, which arises from the transformation of ocular melanocytes, is not known. A fraction of CN patients may develop uveal melanoma. The objective of this study was to investigate the association between CN and BK polyomavirus (BKPyV), a small DNA tumor virus. Serum IgG antibodies which react with BKPyV antigens were analyzed. An indirect E.L.I.S.A. using synthetic peptides that mimic BKPyV antigens was employed...

PURPOSE: To evaluate Verteporfin photodynamic therapy (PDT) as primary treatment for small, posterior choroidal melanoma. DESIGN: Retrospective cohort review. SUBJECTS, PARTICIPANTS AND CONTROLS: Retrospective case note review of 20 patients with small juxtapapillary and juxtafoveal choroidal melanomas treated with PDT at the Liverpool Ocular Oncology Clinic. METHODS: Patient and tumour characteristics, PDT session details, visual acuity and B-scan ultrasonography measurements as well as colour fundus photographs at each examination were collated and analysed...

AIMS: Orbital extraocular extension of choroidal melanoma is very rare with small melanomas. We report the case of a patient whose small choroidal melanoma was initially overlooked and was revealed by a large extrascleral extension. METHODS: A 48-year-old Caucasian woman presented with sudden total visual loss in the right eye. Multicolor imaging of the fundus showed right optic disc edema and an orange and green lesion near the optic disc. The diagnosis of unilateral optic neuritis was made...

AIM: To investigate whether lower radiation doses may yield similar outcome measures to those from the COMS trial. METHODS: A literature review of English language articles was performed using the PubMed database of the U.S. National Library of Medicine and the Cochrane Central Register of Controlled Trials using the following keywords: uveal melanoma, choroidal melanoma, primary uveal malignant melanoma, iodine-125 brachytherapy, local recurrence, local treatment failure, and local tumor control...

BACKGROUND/AIMS: To report a case and the histopathology of uveal melanoma cell seeding following transretinal tumor biopsy for a suspected uveal lesion. METHODS: Interventional case report. RESULTS: A 66-year-old male presented with a pigmented perilimbal episcleral lesion overlying an intraocular mass at the pars plana, 3.5 years after transretinal biopsy and ruthenium plaque brachytherapy for a choroidal melanoma at the posterior pole. The patient underwent enucleation of the eye...

Purpose: Adenocarcinomas or adenomas derived from pigmented ciliary epithelium (APCE) are exceptionally rare ocular tumors. These tumors have pigmented and epithelioid features, and some APCEs are negative for keratin markers and positive for melanocytic markers. It is especially difficult to distinguish APCEs from uveal melanoma (UM). Accordingly, we examined protein expression and genetic mutations associated with APCE to facilitate diagnosis. Methods: Five APCE and 11 UM samples were obtained from patients during surgical resection at our institute...

Importance: Although radiotherapy has been used more frequently in past decades for the management of large melanomas, long-term efficacy of proton beam irradiation (PBI) of large choroidal melanomas has not been reported. Objective: To evaluate long-term outcomes in patients who underwent PBI for the treatment of large choroidal melanomas. Design, Setting, and Participants: Data were obtained at a single Boston, Massachusetts, academic tertiary referral practice for this retrospective cohort study...

BACKGROUND: Orbital exenteration is a radical surgical procedure resulting in deformity. It involves removal of the globe, optic nerve, extra-ocular muscles, orbital fat, lacrimal gland, and peri-osteum. Sino-orbital fistula (SOF) formation is a common documented post-operative complication, usually connecting the orbit and the ethmoid sinus. SOFs can cause leaks of serous fluid, and act as an entry site for pathogens into the orbit leading to socket infection and breakdown. METHODS: This retrospective study analyzed exenterations performed over a 22-year period (1993-2015) at the National Ocular Oncology Service Centre for Scotland...

Melanoma is the most common type of primary cancer to affect the adult eye. Approximately 95% of ocular melanomas are intraocular and arise from the uvea (i. e. iris, ciliary body, and choroid), while the remaining 5% are located in the conjunctiva. Although both uveal and conjunctival melanomas are thought to derive from malignantly transformed melanocytes, uveal melanoma is clinically and biologically distinct from conjunctival melanoma, and indeed from its more common cutaneous counterpart. Intense efforts have been recently made to understand the molecular biology involved in the development of ocular melanomas, and in their progression...

Retinal perforation with vitreous seeding is an uncommon condition of treatment-naïve choroidal malignant melanoma. We reported a 52-year-old male who had a pigmented tumor protruding from choroid of his right eye. He had only black shadow sensation for 4 months then a rapid deterioration of vision. Fundus examination showed vitreous haze with many pigmented materials. B-scan ultrasonography revealed a mass with low internal reflectivity and vitreous opacity. The eyeball was enucleated and a stage IIIA melanoma was confirmed by the pathologist...

BACKGROUND: Choroidal malignant melanoma is a rare intraocular cancer in Asian Indian population. There is a paucity of data from our population comparing iodine 125 (I-125) brachytherapy and enucleation. AIM: This study aims to compare two groups of choroidal melanoma patients treated with either I-125 brachytherapy or enucleation in the Asian Indian population. OBJECTIVES: To evaluate the long-term morbidity and mortality rates in choroidal melanoma patients treated with either I-125 brachytherapy or enucleation...

The CATANA proton therapy center was the first Italian clinical facility making use of energetic (62 MeV) proton beams for the radioactive treatment of solid tumors. Since the date of the first patient treatment in 2002, 294 patients have been successful treated whose majority was affected by choroidal and iris melanomas. In this paper, we report on the current clinical and physical status of the CATANA facility describing the last dosimetric studies and reporting on the last patient follow-up results. The last part of the paper is dedicated to the description of the INFN-LNS ongoing activities on the realization of a beamline for the transport of laser-accelerated ion beams for future applications...
