Background: To reveal clinical findings related to metastatic conjunctival melanoma.
Methods: 10 ophthalmic oncology centres (9 countries and 4 continents) shared data to create a large clinical case series. The main outcome measures were the incidence and cumulative risk of systemic metastasis, study mortality rates and Kaplan-Meier patient mortality after developing conjunctival melanoma metastasis.
Purpose: To report new indications for deep temporalis fascia (DTF) grafts in the ophthalmic field.
Methods: Monocentric retrospective interventional case series study. All the patients who underwent a DTF graft in an unpublished new indication over the study period (May 2020-October 2023) were included.
Purpose: Patients with large uveal melanomas are at major risk of liver metastases. Some patients are reluctant to undergo the standard treatment (ie, immediate enucleation). Proton therapy yields 5-year local control rates and eyeball retention of >85% and ≈20% in large uveal melanomas.

The aim of this study was to assess the value of optical coherence tomography-angiography (OCT-A) for the diagnosis of RM in patients with choroidal melanoma treated with PBT.
Materials & Methods: This 2-year prospective, descriptive, single-center study included patients treated with PBT for choroidal melanoma.
Although its incidence has increased over the last decades, conjunctival melanoma (CM) remains a rare but challenging periocular malignancy. While there is currently no recognized standard of care, "no-touch" surgical excision followed by adjuvant treatments is usually recommended. Despite its small size, managing CM is challenging for clinicians.

In uveal melanomas, the existence and identity of specific subpopulations, their biological function and their contribution to metastasis remain unknown. Here, in multiscale analyses using single-cell RNA sequencing of six different primary uveal melanomas, we uncover an intratumoral heterogeneity at the genomic and transcriptomic level.

Materials And Methods: Monocentric retrospective study of all consecutive patients treated by TACE using melphalan and 250μm calibrated microspheres between 2004 and 2016.
Background: To relate conjunctival melanoma characteristics to local control.
Methods: Retrospective, registry-based interventional study with data gathered from 10 ophthalmic oncology centres from 9 countries on 4 continents. Conjunctival melanoma patients diagnosed between January 2001 and December 2013 were enrolled in the study.
Purpose: Normal tissue complication probability (NTCP) models could aid the understanding of dose dependence of radiation-induced toxicities after eye-preserving radiotherapy of choroidal melanomas. We performed NTCP-modeling and established dose-response relationships for visual acuity (VA) deterioration and common late complications after treatments with proton therapy (PT).
Design: Retrospective study from single, large referral center.
Purpose: The aim of this study was to compare the functional and anatomical effectiveness of photodynamic therapy (PDT) versus proton beam therapy (PBT) in a real-life setting for the treatment of circumscribed choroidal hemangioma.
Methods: A total of 191 patients with a diagnosis of circumscribed choroidal hemangioma and treated by PBT or PDT were included for analyses.
Results: The 119 patients (62.
Introduction: conjunctival melanomas have high local relapse rates. Oncologic and visual outcomes can be improved with proton therapy and no-touch surgery.
Material And Methods: a monocentric retrospective study of consecutive patients treated with surgery and proton therapy for conjunctival melanoma was conducted.
Purpose: Peripheral exudative haemorrhagic chorioretinopathy (PEHCR) is a rare disorder that is often misdiagnosed. The aim of this study was to better characterise PEHCR and to assess treatment options.
Material And Methods: Retrospective multicentric chart review.
Purpose: The use of planar ultra-widefield fundus photography (UWF) may result in distortions and inaccurate measurement. The aim of the study was to evaluate the accuracy of UWF instead of the standard narrow field (SF) for the treatment planning phase of ocular tumours.
Methods: Distortions between conformal SF and UWF were assessed in 43 patients with choroidal melanoma treated with either proton therapy or brachytherapy.
Over the last few years, we have seen constant development of molecular pathology for the care of patients with cancer. The information obtained from molecular data has transformed our thinking about the biological diversity of cancers, particularly in the field of ophthalmic oncology. It has reoriented the way in which therapeutic decisions and decisions concerning patient surveillance are made, both in the area of pediatric cancers, including rhabdomyosarcoma and retinoblastoma, and adult cancers, such as uveal melanoma and lymphomas.

Objective: To evaluate the accuracy of the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual in estimating metastatis and mortality rates of conjunctival melanoma.
Design, Setting, And Participants: This international, multicenter, registry-based case series pooled data from 10 ophthalmic oncology centers from 9 countries on 4 continents.
Purpose: To determine the size at which choroidal melanomas can metastasize and to report the characteristics of small fatal choroidal melanomas (SFCM).
Design: Retrospective case series.
Methods: Ten ocular oncology services submitted 45 patients with a choroidal melanoma 3 mm or less in thickness and 9 mm or less in largest basal diameter (LBD), when treated, who developed metastases.
Purpose: To evaluate the use of the Lens Opacities Classification System III grading (LOCS III) for the characterization of radiation-induced cataract, and to correlate the proton beam projection onto the lens with cataract location and grade as defined by the LOCS III.
Design: Prospective, interventional case series.
Methods: Fifty-two consecutive patients with cataract following proton therapy were included.
Relatively little is known about the genetic aberrations of conjunctival melanomas (CoM) and their correlation with clinical and histomorphological features as well as prognosis. The aim of this large collaborative multicenter study was to determine potential key biomarkers for metastatic risk and any druggable targets for high metastatic risk CoM. Using Affymetrix single nucleotide polymorphism genotyping arrays on 59 CoM, we detected frequent amplifications on chromosome (chr) 6p and deletions on 7q, and characterized mutation-specific copy number alterations.

Whether the degree of invasion influences outcomes is debated. We evaluated the outcomes and management of conjunctival carcinomas defined as ≤0.

The occurrence of choroidal metastases has increased steadily due to the longer survival of metastatic patients and the improvement of diagnostic tools. Fundoscopy, ultrasonography, and fluorescein angiography are now complemented by indocyanine green angiography and optical coherence tomography.
