Objective: the aim is to review the physiology and the pathology of optic nerve disorders.
Changes in parafoveal retinal thickness after bariatric surgery in type 2 diabetics
Bariatric surgery induces an instant normalisation of blood glucose in as many as 80% of patients with type 2 diabetes. It has been previously reported that diabetic retinopathy (DR) is stable within one year after bariatric surgery. In this study,...
Two illustrative cases of AZOOR
The authors present two illustrative cases of acute zonal occult outer retinopathy (AZOOR) which causes acute idiopathic blind spot enlargement. The disease is characterised by sudden loss of outer retinal function associated with photopsia, with minimal or no fundoscopic changes...
Glaucoma and capillary perfusion
Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...
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...
Does methanol poisoning require ophthalmic investigation?
The authors report a case series of 21 patients (41 eyes) diagnosed with acute methanol poisoning following an outbreak in Tunisia in 2020. All patients underwent a complete ophthalmological examination including visual fields, colour vision test and optical coherence tomography...Preparing for the Duke Elder Award
The Duke Elder examination is an undergraduate ophthalmology exam, conducted by the Royal College of Ophthalmologists (RCOphth) and undertaken by students with an interest in ophthalmology. It is a two-hour, 90-question, multiple choice exam with a broader curriculum than that...
The Retinal Atlas (2nd Edition)
Those readers familiar with the first edition of The Retinal Atlas will appreciate the comprehensive nature of this publication, and this latest version incorporates retinal images generated by recently developed imaging technology. As the title suggests, this hardcover version is...
Choroidal and RNFL thickness in patients with OSAS
In obstructive sleep apnoea syndrome (OSAS), hypoxia secondary to repetitive apnoeic episodes leads to blood pressure variations and haemodynamic changes. There is also intermittent activation of the sympathetic system when the patient is aroused from sleep during apnoeic episodes. OSAS...
OCT prognostic factors in AMD patients with peripapillary choroidal neovascularisation
In this retrospective study the authors aimed to investigate the correlation between optical coherence tomography (OCT) findings and visual acuity outcomes after treatment with intravitreal bevacizumab (IVB) injections for age-related macular degeneration (AMD) patients with peripapillary choroidal neovascularisation (PPCNV). Data...
Comparison of paediatric migraine and healthy controls using optical coherence tomography angiography
The authors present a cross-sectional study which recruited patients with paediatric migraine without aura along with age and sex-matched healthy controls. Both groups were recruited following attendance to an ophthalmology outpatient clinic. Children diagnosed with any of the following were...
