Purpose: To report a case of age-related hypertrophy of the nonpigmented ciliary epithelium (ARH-NPCE) clinically resembling a ciliary body melanoma and report the optical coherence tomography angiography (OCTA) findings associated with this lesion. Observations: A 51-year-old male was referred for evaluation of a deeply pigmented ciliary body mass with extension through the iris root. Iridocyclectomy was performed due to concern for ciliary body melanoma. Histopathologic analysis was instead consistent with ARH-NPCE, also known as Fuchs' adenoma...

BACKGROUND: Uveal melanoma accounts for 85% of the ocular melanomas and has an increased risk of hematogenous spread, most commonly to the liver. After curative intent therapy like surgery and radiation, fifty percent of patients present with distant metastasis. Metastatic uveal melanoma (MUM) does not harbor typically targetable mutations, e.g., BRAF as in cutaneous melanoma. As a result, there is no proven therapy for MUM. Various chemotherapy and immunotherapy regimens have been tried and only partial response (PR) is the best that has been achieved in most of the cases...

PURPOSE: Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. Iris melanoma comprises 4% to 10% of all UMs and has a lower mortality rate. The genetic changes in iris melanoma are not as well characterized as ciliary body or choroidal melanoma. The aim of this study was to gain more insight into the genetic background of iris melanoma and iris nevi. DESIGN: Multicenter, retrospective case series. PARTICIPANTS: Patients diagnosed with iris melanoma or iris nevi who underwent surgical intervention as primary or secondary treatment...

PURPOSE: Patients with uveal melanoma (UM) undergo lifelong follow-up as metastases can occur more than 20 years after diagnosis. Little is known about the quality of life (QoL) of UM survivors over such an extended period. To investigate their QoL, we used various estimating factors. METHODS: A cohort of patients diagnosed and treated for UM with regularly scheduled follow-up visits was asked to fill in a European Organization for Research and Treatment of Cancer (EORTC) questionnaire comprised of the EORTC QLQ-C30 and EORTC QLQ-OPT30 modules...

Purpose: Ciliary body mesectodermal leiomyoma is a rare, benign smooth muscle tumor that typically presents in women in the second to fourth decade of life. The diagnosis is typically based on clinical color, funduscopic appearance, transillumination properties, and B-scan ultrasonography. Methods: We present a patient with a 360° ciliary body mass with transillumination and ultrasonographic properties consistent with a ring melanoma. Results: This case emphasizes the difficulty in differentiating the benign leiomyoma from similar appearing malignant tumors such as melanoma...

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...

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...

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...

BACKGROUND: Accurate survival prognostication for patients with uveal melanoma (UM) enables effective patient counselling and permits personalised systemic surveillance for the early detection of metastases and, in high-risk patients, enrolment in any trials of systemic adjuvant therapy. The aim of this work is to determine the success of prognostic UM tumour biopsy using an improved surgical approach and optimised sample handling workflow. METHODS: Patients with UM treated by primary radiotherapy between 2011 and 2013 and who underwent a prognostic biopsy with cytology, multiplex ligation-dependent probe amplification and/or microsatellite analysis were included...

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...
