Iris melanoma in an Australian cohort.

Background: To report the clinicopathological features and epidemiology of iris melanoma in Queensland, Australia.

Methods: This was a retrospective study of 86 patients with iris melanoma treated between 2001 and 2022 at the Queensland Ocular Oncology Service, Brisbane, Australia. Main outcome measures included demographics, clinical and phenotypic features, age-adjusted incidence and relative survival.

Combined photodynamic therapy and transpupillary thermotherapy for small choroidal melanoma.

Objective: The objective of this study was to determine whether combining verteporfin-based photodynamic therapy (PDT) and transpupillary thermotherapy (TTT) achieves adequate tumour control while maintaining visual acuity in individuals with small choroidal melanoma of amelanotic, melanotic, and variable pigmentation.

Design: Individuals with posterior choroidal melanomas up to 3 mm in height underwent verteporfin-based PDT followed by immediate TTT. Further combined laser therapy was performed if a poor response was noted at 12 weeks or beyond.

Conjunctival Lymphoma.

Lymphoma of the conjunctiva is an ocular malignancy derived from clonal proliferation of lymphocytes. The majority of conjunctival lymphoma is extranodal marginal zone B-Cell lymphoma (EMZL), however diffuse large B-cell (DLBCL), follicular (FL), mantle cell (MCL) and T- cell subtypes are also seen. Clinical manifestations are non-specific, but include unilateral or bilateral painless salmon-pink conjunctival lesions.

Choroidal melanoma with synchronous Fuchs' adenoma and novel ATRX mutation.

Background: To report a case of Fuchs' adenoma occurring in an eye with a large choroidal melanoma. We have reviewed the literature to describe the clinical presentation, ultrasound characteristics and pathological features of these entities.

Case Presentation: A 69-year-old Caucasian man presented with vision loss from a large choroidal melanoma.

Genomic analysis of adult case of ocular surface giant congenital melanocytic nevus and associated clinicopathological findings.

Introduction: Conjunctival nevi are the most common tumor of the ocular surface. There are some rare reports of so-called 'giant' conjunctival nevi. We report a case of a 47-year-old female with a cutaneous and ocular surface giant congenital melanocytic nevus and describe her clinical course.

Whole genome landscapes of uveal melanoma show an ultraviolet radiation signature in iris tumours.

Uveal melanoma (UM) is the most common intraocular tumour in adults and despite surgical or radiation treatment of primary tumours, ~50% of patients progress to metastatic disease. Therapeutic options for metastatic UM are limited, with clinical trials having little impact. Here we perform whole-genome sequencing (WGS) of 103 UM from all sites of the uveal tract (choroid, ciliary body, iris).

A Panel of Circulating MicroRNAs Detects Uveal Melanoma With High Precision.

Purpose: To determine if a circulating microRNA (miRNA) panel could be used to distinguish between uveal melanoma and uveal nevi.

Methods: We report on a multicenter, cross-sectional study conducted between June 2012 and September 2015. The follow-up time was approximately 3 to 5 years.

Deep sequencing of uveal melanoma identifies a recurrent mutation in PLCB4.

Next generation sequencing of uveal melanoma (UM) samples has identified a number of recurrent oncogenic or loss-of-function mutations in key driver genes including: GNAQ, GNA11, EIF1AX, SF3B1 and BAP1. To search for additional driver mutations in this tumor type we carried out whole-genome or whole-exome sequencing of 28 tumors or primary cell lines. These samples have a low mutation burden, with a mean of 10.

Retrospective study of an as required dosing regimen of intravitreal bevacizumab in neovascular age-related macular degeneration in an Australian population.

Purpose: To investigate the efficacy of intravitreal bevacizumab for the treatment of neovascular age-related macular degeneration (AMD) using an as required dosing regimen.

Methods: A retrospective study of 210 patients (231 eyes) with choroidal neovascularization resulting from neovasacular AMD. Patients were treated with 1.

Sutureless vitrectomy.

Sutureless vitrectomy has rapidly been accepted as an essential part of a vitreoretinal surgical setup. The size and structure of the wound along with near intact conjunctival covering makes the incision self-sealing and safe. This allows the vitrectomy instruments to be used without creating an initial limited peritomy to expose bare sclera, and obviates the need for sutures at the end of the procedure.
