Intravitreal bevacizumab for the treatment of choroidal haemangiomas.

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

Methods: This was a retrospective review of all patients treated with at least 3 bevacizumab injections for CCH-associated SRF between May 2020 and August 2023 in Moorfields eye hospital. Outcome measures included change in best corrected visual acuity (BCVA), change in patient reported symptoms, change in SRF and change in central subfield thickness (CSFT).

Preclinical and Clinical Pharmacokinetics of a New Preservative-Free Bimatoprost 0.01% Ophthalmic Gel to Treat Glaucoma and Ocular Hypertension.

Pharmacokinetic evaluation of ocular penetration and systemic accumulation of preservative-free bimatoprost 0.01% ophthalmic gel (PFB 0.01% gel).

Posterior uveal biopsy and the trans-scleral Essen forceps biopsy technique.

Background: Differentiating neoplastic and non-neoplastic uveal tumours can present a diagnostic challenge; intra-ocular biopsy may be necessary. The novel trans-scleral Essen Forceps biopsy (TSEB) technique can improve diagnostic yield compared to fine needle aspiration biopsy (FNAB). We present a case demonstrating the technique and its added value.

Artificial Intelligence to Facilitate Clinical Trial Recruitment in Age-Related Macular Degeneration.

Objective: Recent developments in artificial intelligence (AI) have positioned it to transform several stages of the clinical trial process. In this study, we explore the role of AI in clinical trial recruitment of individuals with geographic atrophy (GA), an advanced stage of age-related macular degeneration, amidst numerous ongoing clinical trials for this condition.

Design: Cross-sectional study.

Assessing large language models' accuracy in providing patient support for choroidal melanoma.

Purpose: This study aimed to evaluate the accuracy of information that patients can obtain from large language models (LLMs) when seeking answers to common questions about choroidal melanoma.

Methods: Comparative study comparing frequently asked questions from choroidal melanoma patients and queried three major LLMs-ChatGPT 3.5, Bing AI, and DocsGPT.

Aim: To report local tumour control, metastasis and survival rates of patients with small choroidal melanoma (CM) after treatment with ruthenium-106 (Ru-106) plaque brachytherapy.

Methods: Retrospective case series of 353 consecutive eyes with small CM (thickness ≤2.5 mm and largest basal diameter ≤16 mm) treated with Ru-106 brachytherapy at the London Ocular Oncology Service, between October 2004 and May 2019.

The Fight Tumour Blindness Registry: Efficient capture of high-quality real-world data in uveal melanoma.

Objective: To describe the development of a web-based data collection tool to track the management and outcomes of uveal melanoma patients.

Design: Description of a clinical registry.

Participants: Patients with uveal melanoma.

Effect of corneal cross-linking on biomechanical changes following transepithelial photorefractive keratectomy and femtosecond laser-assisted LASIK.

To evaluate the change in corneal biomechanics in patients with postoperative ectasia risk when combining two common laser vision correction procedures (tPRK and FS-LASIK) with cross-linking (in tPRK Xtra and FS-LASIK Xtra). The study included 143 eyes of 143 myopic, astigmatic patients that were divided into non-cross-linked refractive surgery groups (non-Xtra groups, tPRK and FS-LASIK) and cross-linked groups (Xtra groups, tPRK Xtra and FS-LASIK Xtra) according to an ectasia risk scoring system. The eyes were subjected to measurements including the stress-strain index (SSI), the stiffness parameter at first applanation (SP-A1), the integrated inverse radius (IIR), the deformation amplitude at apex (DA), and the ratio of deformation amplitude between apex and 2 mm from apex (DARatio2mm).

Is Tumour Thickness Measurement Required for MOLES Scoring of Melanocytic Choroidal Tumours?

Introduction: It can be challenging to distinguish between choroidal naevi and melanomas in the community setting, particularly without access to ultrasonography (US), required to measure the thickness of melanocytic choroidal tumours. We aimed to determine whether thickness measurement is required for MOLES scoring of melanocytic choroidal tumours.

Methods: The dataset of a recent MOLES evaluation was reviewed.

Safety and Efficacy of Mucograft Porcine Collagen Bioengineered Acellular Dermal Matrix as a Spacer Graft in Lower Eyelid Elevation Surgery.

Background: Recent regulatory changes have limited the access to a widely used commercially available bioengineered acellular dermal matrix (BADM) product as a spacer graft in the surgical correction of lower eyelid retraction. We report our off-label usage of Mucograft, a porcine BADM, as an alternative BADM.

Methods: A retrospective review was conducted of patients undergoing bilateral lower lid surgery with Mucograft (12 eyes) at a single institution.

Eccentric Viewing Training for Age-Related Macular Disease: Results of a Randomized Controlled Trial (the EFFECT Study).

Purpose: Eccentric viewing training for macular disease has been performed for > 40 years, but no large studies including control groups have assessed the benefits of this training. The EFFECT (Eccentric Fixation From Enhanced Clinical Training) study is a large randomized controlled trial of 2 types of eccentric viewing training.

Design: Randomized controlled trial.

Evaluation of changes in corneal biomechanics after orthokeratology using Corvis ST.

Purpose: To investigate the alterations in corneal biomechanical metrics induced by orthokeratology (ortho-k) using Corvis ST and to determine the factors influencing these changes.

Method: A prospective observational study was conducted to analyze various Corvis ST parameters in 32 children with low to moderate myopia who successfully underwent ortho-k lens fitting. Corneal biomechanical measurements via Corvis ST were acquired at six distinct time points: baseline (pre) and 2 h (pos2h), 6 h (pos6h), and 10 h (pos10h) following the removal of the first overnight wear ortho-k, one week (pos1w) and one month (pos1m) subsequent to the initiation of ortho-k.

Subconjunctival Ocular Argyrosis following Treatment with Ruthenium 106 Brachytherapy for Choroidal Melanoma.

Introduction: Ruthenium-106 (Ru-106) brachytherapy is one of the commonest eye-sparing treatments for choroidal melanoma. These patients require long-term surveillance of the treated tumour remnant to ensure there is no local recurrence. New or progressive pigmented lesions in treated eyes are often regarded as suspicious - especially if there are concerns of extra-scleral extension.

Effect of intrastromal corneal ring segments on in vivo corneal biomechanics in keratoconus: 1-year results.

Purpose: To evaluate the 1-year effects of the implantation of intrastromal corneal ring segments (ICRS) in keratoconus (KC) on the dynamic corneal response (DCR) parameters obtained with the Corvis.

Setting: Fernández-Vega Ophthalmological Institute, Oviedo, Spain.

Design: Prospective, single-center, clinical study.

Pediatric ocular melanoma: a collaborative multicenter study and meta-analysis.

Purpose: To investigate clinical manifestations and prognoses in pediatric patients (≤12 years old) with ocular melanoma.

Methods: This was a retrospective, multicenter cohort study with individual participant data (IPD) meta-analysis pooling available published cases, and unpublished cases from an international collaboration of seven ocular oncology centers.

Results: There were 133 eyes of 133 pediatric patients with choroidal or ciliary body (n = 66 [50%]), iris (n = 33 [25%]), conjunctival (n = 26 [19%]), and eyelid (n = 8 [6%]) melanoma.

PRELP secreted from mural cells protects the function of blood brain barrier through regulation of endothelial cell-cell integrity.

Proline/arginine-rich end leucine-rich repeat protein (PRELP), is a small secreted proteoglycan expressed by pericytes and vascular smooth muscle cells surrounding the brain vasculature of adult mouse. We utilised a knockout ( ) mouse model to interrogate vasculature integrity in the brain alongside performing in vitro assays to characterise PRELP application to endothelial cells lines. Our findings were supplemented with RNA expression profiling to elucidate the mechanism of how PRELP maintains neurovasculature function.

An overview of transcript alterations detected during retinoblastoma genetic screening.

Identification of pathogenic variants aids in the clinical management of families with retinoblastoma. We routinely screen DNA for variants, but transcript analysis can also be used for variant screening, and to help decide variant pathogenicity. DNA was screened by conformation analysis followed by Sanger sequencing.
