Resolution of mid-peripheral schisis in x-linked retinoschisis with the use of dorzolamide

X-linked retinoschisis (XLRS) is an early onset hereditary retinal dystrophy. It is caused by mutations of the RS1 gene. Common manifestations of XLRS are schitic lesions at the macula, as well as infero-temporal schisis. Carbonic anhydrase inhibitors have previously been...

The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography

Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...

Comprehensive review of inherited retinal diseases

The authors offer an up-to-date review of inherited retinal diseases (IRDs). In each section the authors discuss the molecular basis of disease, genotype and clinical manifestation. They also discuss the investigation findings and current evidence in the treatment of the...

Stargardt disease in a Turkish cohort

The authors present a study of 27 Turkish patients who were seen in a single centre over a five-year period. All patients had macular optical coherence tomography (OCT), colour fundus photography and 30-2 Humphery visual fields performed, along with clinical...

PAX6 methylation and myopia

The authors present a case control study of 41 adolescents (age 12–14) with myopia and 39 age- and sex-matched non-myopic controls. The myopic patients were sub-divided into mild, moderate and severe myopia subgroups. DNA was extracted from peripheral blood samples...

Bardet Biedl refractive error

This is a retrospective cross-sectional study of 45 patients with genetically diagnosed Bardet Biedl syndrome. Patients with biallelic defects in any gene known to cause Bardet Biedl syndrome were eligible for inclusion. Patients underwent cycloplegic refraction and keratometry. The mean...

Long-term incidence and survival trends in retinoblastoma in the USA

The authors present a retrospective observational study of 5730 patients diagnosed with retinoblastoma between 1996 and 2018. Data on demographics, age at diagnosis, treatment and survival were extracted from national registries with coverage of 99% of the population of the...

Nystagmus in infants (0–1 year)

This article from a tertiary hospital in Jerusalem documents the examination and investigations of 147 infants aged 0–1 years with nystagmus. The most common pathologies were albinism (59%) and inherited retinal dystrophy (IRD) (21%). They had eight patients with vertical...

Usher syndrome patient reported outcomes

The authors present a systematic review of the literature on patient-reported outcomes in Usher syndrome; a leading cause of deaf-blindness. A total of 27 studies were included, and there was a strong bias towards studies from the US and Europe...

Idebenone for Leber hereditary optic neuropathy

The authors present a meta-analysis of studies reporting the effects of idebenone treatment on visual acuity (VA) in patients with Leber hereditary optic neuropathy (LHON), the most common inherited mitochondrial disorder. They included randomised controlled trials, non-randomised controlled trials and...

Gene Vision launched to support those diagnosed with genetic eye diseases

A new website, Gene Vision (https://gene.vision), has been developed by Professor Mariya Moosajee and Dr Alex Yeong, supported by Dr Peter Thomas (Director of Digital Innovation at Moorfields Eye Hospital). The new site is intended for adults, children and their families who are diagnosed with rare genetic eye diseases.

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...
