Underlying Ciliary Body Uveal Melanoma in a Patient with Chronic Lymphocytic Leukemia Presenting for Hyphema.

Diagnostics (Basel) 2022 May 25;12(6). Epub 2022 May 25.

Clinical Department of Ophthalmology, Carol Davila University of Medicine and Pharmacy, 020021 Bucharest, Romania.

(1) Background: Ciliary body uveal melanoma is a rare subtype of uveal melanoma which comprises 3-5% of melanomas, an immunogenic cancer, and can present multifaceted initial clinical manifestations, masquerading as various ocular pathologies. Chronic lymphocytic leukemia (CLL) presents immunodeficiency and risk for the development of a secondary malignancy, with Bruton's tyrosine kinase inhibitor treatment having a mutagenic effect and a secondary anti-platelet aggregation effect. We present the case of a 65-year-old patient undergoing treatment for CLL with ibrutinib who presented with recurrent hyphema that masked an underlying, inferiorly situated, ciliary body uveal melanoma; (2) Methods: Retrospective case review; (3) Results: An ophthalmological examination together with imaging via mode B ultrasound and contrast-enhanced magnetic resonance imaging resulted in the clinical and imagistic diagnosis of a ciliary body uveal melanoma.

Potential of Aqueous Humor as a Liquid Biopsy for Uveal Melanoma.

Int J Mol Sci 2022 Jun 2;23(11). Epub 2022 Jun 2.

The Vision Center at Children's Hospital Los Angeles, Los Angeles, CA 90027, USA.

Tumor biopsy can identify prognostic biomarkers for metastatic uveal melanoma (UM), however aqueous humor (AH) liquid biopsy may serve as an adjunct. This study investigated whether the AH of UM eyes has sufficient circulating tumor DNA (ctDNA) to perform genetic analysis. This is a case series of 37 AH samples, taken before or after radiation, and one tumor wash sample, from 12 choroidal and 8 ciliary body (CB) melanoma eyes. Read More

Surgical Approach in Intraocular Tumors

Turk J Ophthalmol 2022 04;52(2):125-138

Ankara University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey

Surgery in intraocular tumors is done for excision/biopsy and the management of complications secondary to the treatment of these tumors. Excision/biopsy of intraocular tumors can be done via fine-needle aspiration biopsy (FNAB), transretinal biopsy (TRB), partial lamellar sclerouvectomy (PLSU), and endoresection. FNAB, TRB, and PLSU can be used in tumors that cannot be diagnosed by clinical examination and other ancillary testing methods. Read More

Feline Uveal Melanoma Review: Our Current Understanding and Recent Research Advances.

Vet Sci 2022 Jan 26;9(2). Epub 2022 Jan 26.

The Ophthalmology Department, The University of Edinburgh Hospital for Small Animals (HfSA), Royal (Dick) School of Veterinary Studies (R(D)SVS), Easter Bush Campus, Midlothian EH25 9RG, UK.

Melanocytic neoplasia is the most common form of ocular tumour in cats, accounting for 67% of cases in an analysis of 2614 cases of primary ocular neoplasia. Feline diffuse iris melanoma (FDIM) is by far the most common form of ocular melanocytic neoplasia, with limbal melanomas and atypical melanoma (melanoma affecting the choroid or ciliary body) infrequently recognised. Early lesions begin as flat areas of pigmentation of the iris, known as iris melanosis. Read More

The unfolded protein response and the biology of uveal melanoma.

Biochimie 2022 Jun 29;197:9-18. Epub 2022 Jan 29.

Sydney Pharmacy School, Faculty of Medicine and Health, University of Sydney, Sydney, NSW, 2006, Australia. Electronic address:

Uveal melanoma (UM) is a highly metastatic ocular cancer that arises from the melanocytes of the uveal tract (the choroid, ciliary body and iris). Despite a growing understanding of UM biology, effective systemic treatments are currently lacking and the cancer has an extremely poor prognosis. Therefore, identifying novel agents that act by new tumorigenic mechanisms in UM is essential to address this unmet clinical need. Read More

Small Animal Magnetic Resonance Imaging Laboratory, Mossakowski Medical Research Institute, Polish Academy of Sciences, 02-106 Warsaw, Poland.

Uveal melanoma is the most common intraocular malignancy and arises from melanocytes in the choroid, ciliary body, or iris. The current eye-sparing treatment options include surgical treatment, plaque brachytherapy, proton beam radiotherapy, stereotactic photon radiotherapy, or photodynamic therapy. However, the efficacy of these methods is still unsatisfactory. Read More

Prognostic Biomarkers in Uveal Melanoma: The Status Quo, Recent Advances and Future Directions.

Cancers (Basel) 2021 Dec 25;14(1). Epub 2021 Dec 25.

Laboratory of Clinical and Experimental Pathology, Université Côte d'Azur, Pasteur Hospital, Centre Hospitalier Universitaire de Nice, Biobank BB-0033-00025, 06000 Nice, France.

Uveal melanoma (UM) is the most common malignant intraocular tumour in the adult population. It is a rare cancer with an incidence of nearly five cases per million inhabitants per year, which develops from the uncontrolled proliferation of melanocytes in the choroid (≈90%), ciliary body (≈6%) or iris (≈4%). Patients initially present either with symptoms like blurred vision or photopsia, or without symptoms, with the tumour being detected in routine eye exams. Read More

The Effect of Intraocular Pressure-Lowering Medication on Metastatic Uveal Melanomas.

Cancers (Basel) 2021 Nov 12;13(22). Epub 2021 Nov 12.

Department of Ophthalmology, Erasmus University Medical Center, 3015 CA Rotterdam, The Netherlands.

Background: There has been speculation that IOP-lowering medication, which increases aqueous humor outflow, increases the risk of metastatic uveal melanoma (UM). This hypothesis has not been studied previously but is relevant for UM patients who use IOP-lowering medication. The aim of the current study is to assess the association between the use of intraocular pressure (IOP)-lowering medication and the risk of metastatic UM, and mortality. Read More

Adding the Cancer Genome Atlas Chromosome Classes to American Joint Committee on Cancer System Offers More Precise Prognostication in Uveal Melanoma.

Ophthalmology 2022 04 16;129(4):431-437. Epub 2021 Nov 16.

Department of Ophthalmology, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Purpose: Uveal melanoma (UM) is a rare disease and the most common primary intraocular malignancy in adults, with a high risk of metastases. Reliable prognostication systems are based on anatomic features, as in the tumor-node-metastasis staging of the American Joint Committee on Cancer (AJCC) system, or on genetic information, as in The Cancer Genome Atlas (TCGA) system. Prior evidence suggests that combining both systems may be beneficial. Read More

Chromosome 3 and 8q Aberrations in Uveal Melanoma Show Greater Impact on Survival in Patients with Light Iris versus Dark Iris Color.

Ophthalmology 2022 04 13;129(4):421-430. Epub 2021 Nov 13.

Department of Ophthalmology, Leiden University Medical Center, Leiden, the Netherlands. Electronic address:

Purpose: Individuals with gray, blue, or green eyes have a higher chance of developing uveal melanoma (UM) than those with brown eyes. We wondered whether iris pigmentation might be related not only to predisposition to UM but also to its behavior; therefore, we compared the clinical, histopathologic, and genetic characteristics of UM between eyes with different colors.

Design: We determined iris color in a large cohort of patients enucleated for UM. Read More
