Retinal vessel diameter in pseudoexfoliation

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

Can the angle of origin of the ophthalmic artery predict embolic trajectory?

A retrospective, comparative case-control study was used to test the hypothesis that a risk factor for retinal versus cerebral infarct is the angular origin of the ophthalmic artery from the internal carotid artery. The study compared one group (n=28) who...

Why is there subretinal fluid at the macula?

This is a review article looking at the differential diagnosis of subretinal fluid in the macula that could be diagnosed as central serous chorioretinopathy (CSCR). The authors have categorised them into 12 groups: neovascular diseases, vitelliform lesions, inflammatory diseases, ocular...

Ocular damage from laser pointers

This retrospective study of case notes from a tertiary eye centre over a five-year period, recruited nine children (12 eyes: eight boys) aged 9-15 years. Three presented with deteriorating vision whilst others had retinal changes noted as incidental findings at...

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...

Vigabatrin-induced retinal toxicity detected by 30Hz ERG

The purpose of this study was to assess the role of 30Hz flicker electroretinogram (ERG) as a marker for measuring changes in visual function over time in children receiving vigabatrin. This was an observational study of 11 children with mean...

Associations between cerebral vascular malformations and retinal venous malformations

The authors present a retrospective medical notes review which aimed to understand associations between retinal venous malformations (RVM) and cerebral vascular malformations (CVM). Cases of known CVM over a four-year period were identified. The data extracted from medical records included...

Diary from my elective: a Parisian experience

The author explains how a research institute’s dedication to multidisciplinary collaboration helped him to discover a passion for academic ophthalmology. The elective aspect to the final year of a medical degree, through its change of scenery and immersion into another...

Optical Coherence Tomography: A Clinical and Technical Update

This book is a comprehensive review of the clinical and scientific aspects of optical coherence tomography (OCT). The 255 pages are divided into 11 chapters, each written by a different group of authors. Part I provides viewpoints on the clinical...

Intravitreal bevacizumab vs. ranibizumab in the treatment of macular oedema due to BRVO

This is a randomised, prospective, non-inferiority trial of 75 patients with macular oedema due to a branch retinal vein occlusion (BRVO) who received intravitreal injections of ranibizumab or bevacizumab after 1:1 block randomisation. This study is to measure the difference...

The assessment of pupils and 
pupillary reactions

Understanding pupillary reactions is vital in understanding basic neuro-opthalmology. It is a skill required in eye casualty, clinics and perhaps most importantly, exams. To start at the beginning, the pupil is the central aperture of the iris, its size controlling...
