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...

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...

Optical coherence tomography in patients exposed to vigabatrin

Vigabatrin is used to treat epilepsy and can lead to increased levels of gamma-aminobutyric acid (GABA) in the brain and in the retina leading to binasal visual field defects. Although not the first line of treatment for adults it is...
