Aim: This meta-analysis aimed to compare the efficacy and safety of immune checkpoint blockade for the treatment of ocular melanoma.
Methods: We searched the PubMed, EMBASE, and Cochrane Library databases up to July 2021. Effect sizes (ESs) and corresponding 95% confidence intervals (CIs) were used to compare the outcomes. Efficacy outcomes included complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), objective response rate (ORR), overall survival (OS), progression free survival (PFS). Safety outcomes included adverse events (AEs) and serious adverse event (SAEs).
Results: A total of 16 eligible articles with 848 ocular melanoma patients were included. ICB treatment significantly improved CR (ES=0.02, 95%CI: 0.00-0.03, P=0.023), PR (ES=0.07, 95%CI: 0.05-0.09, P=0.000), SD (ES=0.31, 95%CI: 0.17-0.46, P=0.000), PD (ES=0.69, 95%CI: 0.61-0.77, P=0.000), ORR (ES=0.10, 95%CI: 0.04-0.15, P=0.000), OS (ES=9.68, 95%CI: 7.28-12.07, P=0.000) and PFS (ES=2.88, 95%CI: 2.69-3.07, P=0.000) in patients with ocular melanoma. Moreover, ICB therapies were associated with reduced AEs (ES=0.48, 95%CI: 0.30-0.67, P=0.000) and SAEs (ES=0.31, 95%CI: 0.18-0.45, P=0.000).
Conclusions: ICB therapy showed good efficacy and safety in treating patients with ocular melanoma.

Liverpool Ocular Oncology Research Group, Department of Eye and Vision Science, Institute of Life Course and Medical Sciences (ILCaMS), University of Liverpool, Liverpool, United Kingdom.
Purpose: Testing the validity of a self-supervised deep learning (DL) model, RETFound, for use on posterior uveal (choroidal) melanoma (UM) and nevus differentiation.
Design: Case-control study.
Subjects: Ultrawidefield fundoscopy images, both color and autofluorescence, were used for this study, obtained from 4255 patients seen at the Liverpool Ocular Oncology Center between 1995 and 2020.
Ruthenium-106 brachytherapy and central uveal melanoma.
Int Ophthalmol
January 2025
Department of Ophthalmology, Staedtisches Klinikum Dessau, Brandenburg Medical School Theodor Fontane, Dessau, Germany.
Purpose: Uveal melanoma (UM) is the most common primary ocular malignancy. The size and location of the tumor are decisive for brachytherapy with the β-emitting ruthenium-106 (Ru-106) plaque. The treatment of juxtapapillary and juxtafoveolar UM may be challenging because of the proximity or involvement of the macula and optic nerve and high recurrence rates.

Faculty of Medical and Health Sciences, Tel Aviv University, Israel.
Objective: Pigmentary posterior vitreous detachment (PVD), referred to as "black PVD," is a rare entity describing PVD along with pigment dispersion in the vitreous. There are a few case reports describing pigmentary PVD, yet the association between pigmentary PVD and uveal and optic disc tumors was not described before. The aim of this study was to report the clinical features of patients with pigmentary PVD associated with these tumors.

January 2025
Department of Pediatrics, University of Minnesota Medical School, Minneapolis, MN.
Purpose: Melanoma as a subsequent malignant neoplasm has been described among childhood cancer survivors; however, the risk factors and long-term survival are not well understood.
Methods: We assessed incidence, risk factors, and outcomes for melanoma among participants in the Childhood Cancer Survivor Study cohort. Cumulative incidence and standardized incidence ratios (SIRs) were calculated, and multivariable Cox models were used to determine hazard ratios (HRs) and associated 95% CI for melanoma risk factors.

Klinik für Augenheilkunde, Universitätsklinikum Düsseldorf, Moorenstr. 5, 40225, Düsseldorf, Deutschland.
Background: The ocular surface is directly exposed to environmental influences. Noxae that have already been identified for the ocular surface are heat, air dryness, pollutant gases, fine dust particles and ultraviolet radiation.
Methods: The current literature was used to investigate the relationship between frequent ocular surface diseases and various environmental factors and to analyze their development over the years.
