How common are carotid-cavernous fistulas and what are the neuro-ophthalmic manifestations?

The authors present a retrospective study using the Rochester Epidemiology Project database. The aim was to establish the incidence of carotid-cavernous fistulas (CCF) and outline the associated neuro-ophthalmic patterns. Cases were identified from the database using the following criteria: a...

Testing periods for accommodative and vergence facilities

The authors investigate if there is a significant difference in the number of cycles between the first and second 30-second (FASTS) periods of testing accommodative facility and vergence facility, and explore the possibility of reducing testing time by half. The...

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...

Reclassifying genetic variants in inherited retinal diseases

The authors present a retrospective study of 142 gene sequence variants from 28 patients with vitreoretinal dystrophies which were re-interpreted based on American College of Medical Genetics and Genomics (ACMG) and Association for Molecular Pathology (AMP) guidelines. Overall, there was...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...
