Nanoparticle administration of latanoprost

Glaucoma is a progressive optic neuropathy characterised by increased ocular pressure and loss of retinal ganglion cells. Conventional drug therapy with eye drops to reduce intraocular pressure (IOP) has variable bioavailability and can lead to ocular surface disease. In this...

Suspected vitreous seeding of uveal melanoma

This is a retrospective non-randomised study of 23 patients with consecutive uveal melanoma who underwent diagnostic vitrectomy between the period of January 2000 and November 2013. The reason for vitrectomy was suspected dissemination of tumour cells inside the eye. The...

PD-1 and PD-L1 in exenteration specimens

This is an immunohistochemical study looking at variation in the expression of the programmed death-1 receptor (PD-1) and the programmed cell death ligand-1 (PD-L1), comparing cutaneous malignancies which invaded the orbit with uncomplicated nodular basal cell carcinomas. The authors retrospectively...

Imaging and histological relationship of orbital Schwannomas

This is a retrospective review of 15 patients with orbital Schwannomas comparing the radiological characteristics, in particular the signal intensity on MRI, with the histological sub-types of the tumours. Five patients had MRI imaging alone, three had CT alone and...

Uveal melanoma

Uveal melanoma is the most common primary intraocular tumour. However, they are still rare, with an incidence of 2-8 per million [1]. The presence of a choroidal naevus is a risk factor for uveal melanoma [1]. Patients with choroidal lesions...

A prospective trial of adjuvant therapy for high-risk melanoma

Patients diagnosed with iris, ciliary body or choroidal melanoma of high-risk tumour cytogenetics (monosomy 3>/= 20% of cells), were treated with adjuvant low-dose dacarbacine (DTIC) and interferon –alpha-2b (IFNA-2b), following primary treatment (enucleation, brachytherapy or resection). DTIC was given intravenously...

Outcomes of plaque radiotherapy for retinoblastoma

The study authors evaluate their experience of plaque radiotherapy for retinoblastoma (RB) in 41 eyes of 41 patients that failed intra-arterial chemotherapy (IAC). This was a retrospective review including 21 females and 20 males. Median age was 18 months and...

Brimonidine day and night time IOP

The authors describe a randomised double masked study of 29 participants with ocular hypertension (OHT) who either self-administered 0.2% brimonidine or placebo three times daily for six weeks. Patients were seen during day time and night time visits and had...

Enzymatic clearance of anterior chamber infiltrate in uveitis

Aqueous humour (AH) which fills the anterior chamber (AC) of the eye provides nutrients to the cornea and the lens. Clearance of cellular and particular matter from AH is necessary for good visual acuity. In part this is achieved by...

Germline mutation risk in solitary unilateral retinoblastoma

This study aimed to determine the true risk for germline mutation in a child presenting with solitary unilateral RB and whether this risk differs by age at presentation. This was a retrospective review of 482 cases from 1972-2020. Age groups...

Retinoblastoma management update (part 1): clinical features, diagnosis and genetics

The first of a two part series, this article will discuss the clinical features, diagnosis and genetic aspects of retinoblastoma. Manoj Parulekar is based at Birmingham Children’s Hospital, one of the two designated national retinoblastoma and paediatric ocular oncology treatment...

Practice patterns of uveal melanoma management with Iodine-125 brachytherapy

With the 2006 Collaborative Ocular Melanoma Study Group (COMS) study demonstrating no difference in survival outcomes for participants randomised to either iodine-125 brachytherapy or enucleation, the majority of primary uveal melanomas in the United States are now treated with brachytherapy....
