The International AMD Genomics Consortium study: another success in understanding the complex genetics of AMD

Age-related macular degeneration (AMD) is a neurodegenerative complex disease of the eye and a major cause of blindness and visual impairment among the elderly worldwide. The early stages of the disease are characterised by asymptomatic pigmentary abnormalities and accumulation of...

Neurofibromatosis type 2 – diagnosis, features and MDT approach

NF2 is a genetic condition caused by mutation in a single gene (NF2 gene) on chromosome 22. The NF2 gene provides instructions to produce a protein called merlin, also known as schwannomin. This protein functions as a tumour suppressor, preventing...

Online retinoblastoma surveillance tool

Given the vision and life-threatening course of retinoblastoma (RB), it has become a significant heritable childhood cancer to screen for. To recommend surveillance, risk must be estimated and genetic testing plays a vital role. However, genetic tests vary based on...

Germline testing for uveal melanoma

The authors present a study of 114 consecutive patients presenting with uveal melanoma. Between 1 December 2019 and 1 November 2021 all patients over 18-years-old presenting to their centre with uveal melanoma were offered germline testing for variants in BAP1,...

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...

Patient-reported outcomes in oculoplastic surgery

This is an important if somewhat difficult to grasp article which tries to formally address the subject of patient-reported outcomes in oculofacial surgery. The authors have conducted an extensive review of the literature searching for instruments (questionnaires) which have been...

Gene therapy for inherited retinal disease: the Manchester Ocular Gene Therapy Group MDT service

The authors describe the process set up in Manchester for the optimum delivery and assessment of a new gene therapy treatment for patients with RPE65 IRD. Inherited retinal dystrophies (IRDs) are the second commonest cause of severe visual impairment in...

Reliability of kinetic perimetry in children and young adults

This study reports on normative visual field area, feasibility and repeatability of testing for a large sample size of healthy children and young adults, using Octopus semi-automated kinetic perimetry. Sample included 221 healthy volunteers aged 5-22 years. The study was...

Myopia in Han Chinese

The authors present a case-control study of 361 patients with high myopia (mean spherical equivalent of -6.0DS or lower, and axial length greater than or equal to 26mm) and 749 healthy controls (mean spherical equivalent -1.0 to +1.0DS). They tested...

Complement factor B polymorphism and the phenotype of early age-related macular degeneration

The relationship between complement factor H (CFH) and age-related macular degeneration (AMD) is very well known, but other genetic polymorphisms relating to AMD are more poorly understood. This study was designed to investigate the relationship between complement factor B (CFB)...

Exploiting nature’s randomised trials of eye disease

Confounding and reverse causation in observational ophthalmic epidemiology Traditional observational studies are inherently limited in establishing a causal effect of an exposure on an outcome of interest. One fundamental limitation is confounding, whereby causation is incorrectly attributed to a third...

An update on inherited retinal disorders (part 1) – overview and assessment of inherited retinal disease

Part 2 of this topic can be found here Inherited Retinal Disease (IRD) is the leading cause of blindness certification in the working age population (age 16-64 years) in England and Wales and the second most common in childhood [1]....
