Purpose: To investigate the use of intravitreal bevacizumab for the treatment of subretinal fluid (SRF) and intraretinal fluid associated with circumscribed choroidal hemangiomas.

Methods: This was a retrospective review of all patients treated with at least three bevacizumab injections for circumscribed choroidal hemangiomas-associated SRF between May 2020 and August 2023 in Moorfields eye hospital. Outcome measures included change in best-corrected visual acuity, change in patient-reported symptoms, change in SRF, and change in central subfield thickness.

Article Synopsis
  • This study aims to examine the histopathology and outcomes in patients with retinoblastoma who underwent eye enucleation and had neovascular glaucoma (NVG).
  • The research included 1,420 total cases from five continents, revealing that 16% of patients with NVG were often at higher risk of severe histopathological findings.
  • The findings indicate that NVG is linked to more aggressive forms of the disease and a higher chance of metastasis, emphasizing the need for careful monitoring and treatment in these cases.

Objective: To assess the association of skin color using Fitzpatrick Skin Type (FST) with metastatic risk of uveal melanoma.

Subjects: 854 consecutive patients with uveal melanoma and documented FST.

Methods: Retrospective detailed review of patient charts was performed for FST (type I- white, II-fair, III-average, IV-light brown, V-brown, VI-black), clinical details of the patient and the uveal melanoma, tumor cytogenetic classification according to The Cancer Genome Atlas (TCGA), and outcome of melanoma-related metastasis and death.

Objectives: To determine clinical features and outcomes of posterior scleritis masquerading as uveal melanoma following vaccination against COVID-19 and/or COVID-19 infection.

Subjects/methods: All patients with posterior scleritis referred to our service to rule out intraocular tumour between February 2021 and June 2022, who previously had COVID-19 vaccination and/or infection (n = 8). A retrospective detailed review of patient charts and imaging was carried out.

A woman aged mid 70s with mild learning difficulty presented with eye symptoms, headache and shoulder pains. She was found to have bilateral posterior scleritis secondary to giant cell arteritis. Posterior scleritis is a potentially blinding condition, with ambiguous symptoms and signs, therefore diagnosis is commonly delayed.

Background: The Cancer Genome Atlas (TCGA) classification of genetic alterations in uveal melanoma is widely used for prognostication. We present novel observations on the impact of TCGA Group specifically for iris melanoma.

Methods: This was a retrospective cohort study at a tertiary referral ocular oncology center.

Background: Two major treatment modalities for retinoblastoma, intraarterial chemotherapy (IAC) and intravitreal chemotherapy (IVitC), have superseded external beam radiotherapy for eye salvage. In this new setting our objectives were to evaluate the indications for plaque radiotherapy, complications, and recurrence rates.

Methods: Retrospective detailed review of patient's charts was performed for all subjects treated with plaque radiotherapy for retinoblastoma between January 2015 and December 2020.

Purpose: To determine the clinical features and outcomes of choroidal melanoma initially masquerading as central serous chorioretinopathy (CSCR).

Design: Retrospective case series.

Subjects: All patients with choroidal melanoma, initially misdiagnosed as CSCR elsewhere and evaluated by the Ocular Oncology Service at Wills Eye Hospital from 2004 to 2022, were included.

Background: To assess the long-term visual outcomes in patients with posteriorly located choroidal melanoma treated with ruthenium plaque brachytherapy between January 2013 and December 2015.

Methods: A retrospective review was conducted on consecutive patients treated with ruthenium plaque brachytherapy for post-equatorial choroidal melanoma with available Snellen visual acuity before and after treatment, and the development and treatment of radiation complications.

Results: There were 219 patients with posterior choroidal melanoma treated with ruthenium plaque brachytherapy.

Prompt detection and treatment of local treatment failure after radiotherapy for choroidal melanoma optimises any opportunities for conserving vision and the eye, possibly reducing an increased risk of metastatic disease. Long-term surveillance is therefore required but is hampered by the perceived need to perform ultrasonography, which may not be available at a patient's local hospital. The aim of this study was to determine whether local treatment failure can reliably be detected with colour fundus photography alone, and, if so, in which patients.

Objectives: To determine survival outcomes following enucleation for uveal melanoma. To compare these outcomes with the 8th edition AJCC classification and determine the influence of cytogenetics, using Fluorescent in situ Hybridisation (FISH), on survival. To determine whether failure to gain sufficient sample for cytogenetics using Fine Needle Aspiration Biopsy (FNAB) correlates with survival.

Objective: The objective of this study is to characterise the natural history of conjunctival naevi in a paediatric and adolescent population.

Methods: All children and adolescents referred to Moorfields Ocular Oncology Service for evaluation between January 2015 and 2020 were included. Exclusion criteria included age >20 years old and lack of anterior segment photographs.

Purpose: To report local disease control and all-cause mortality in patients with extraocular extension (EOE) of uveal melanoma undergoing enucleation followed by observation or external beam radiotherapy (EBRT).

Methods: Charts of patients enucleated between January 1, 1997 and December 31, 2019, with histopathological evidence of EOE of uveal melanoma were reviewed.

Results: The cohort comprised 51 patients with a mean age of 67 ± 15 years, 22 (43%) of whom underwent adjuvant postenucleation EBRT.

Objectives: To present the visual acuity (VA) results and complication rates following Artisan intraocular lens (IOL) insertion in vitrectomised eyes.

Methods: Outcome data were collected for all vitrectomised patients who had undergone Artisan IOL insertion between January 2014 and May 2019 at Moorfields Eye Hospital. All those with follow-up greater than 2 months were included in the analysis.

Purpose: A review of the effectiveness, costs, and cost-effectiveness of detection and treatment strategies for glaucoma control in Sub-Saharan Africa (SSA) was conducted.

Methods: Detailed searches were performed using the Ovid Medline, Ovid Embase, The Cochrane Library, Web of Science, Scopus, and LILACS databases up to September 2016. The key Medical Subject Heading search terms used included glaucoma, diagnosis, treatment, effectiveness, costs, cost-effectiveness, and Sub-Saharan Africa.
