Idiopathic intracranial hypertension (IIH)
IIH is a medical condition where the intracranial pressure (ICP) is raised without an obvious cause. The cerebrospinal fluid (CSF) is produced in by the choroid plexus in the lateral ventricles and the roof of the third and fourth ventricles,...
300 MCQs for the Duke Elder Ophthalmology Exam
The Duke Elder undergraduate prize examination is held by the Royal College of Ophthalmologists annually for undergraduate medical students. It is a competitive examination covering clinical ophthalmology as well as the ocular basic sciences, optics, statistics and socio-economic medicine. For...
OCT measures of lateral and medial recti
The authors assessed the agreement of the measurements of the horizontal rectus muscle insertion distance to the limbus and the muscle thickness between three different OCT devices. This was a cross section observation study of 70 eyes of 35 subjects....
Are retinal vein occlusions seasonal? And if so why might that be?
Some studies have reported a strong seasonal pattern to central retinal vein occlusion (CRVO) occurrence with a peak in January, but other studies have failed to replicate this finding. The authors sought to determine data for Stockholm’s seasonal variation in...
Do topical steroids improve visual outcome in the treatment of bacterial keratitis?
The use of topical corticosteroids as an adjunctive treatment to antibiotics in the management of bacterial keratitis remains a controversial issue. The results of the Steroids for Corneal Ulcers Trial (SCUT) – a randomised, double-masked, placebo-controlled trial that recruited patients...
Thrombophilia in patients with retinal vein occlusion
The authors present a retrospective study of the prevalence of thrombophilia in patients with retinal vein occlusion. The study cohort included 88 patients with central retinal vein occlusion (CRVO), 51 patients with branch retinal vein occlusion (BRVO) and 40 controls....
Inhibiting high-risk corneal allografts
The cornea is an immune privileged site and as such corneal transplants are very successful. However, in situations where this privilege is lost the failure rises substantially. To combat rejection inhibition of the immune responses depends on steroids and other...
Blinking and driving
Spontaneous blinking is dependent on cognitive processes and is regulated by a central pacemaker that is highly sensitive to the attention demands and cognitive workload of the visual task in hand. There is evidence of a variability in the frequency...
CD40L activation of human RPE cells
Age-related macular degeneration (AMD) is the leading cause of reduced visual acuity in the elderly worldwide. The risk factors involved in AMD include smoking and diet, while genetics have been shown to have a significant role. Recently a link between...
Using frequency doubling technology perimetry to identify Alzheimer’s disease early
Alzheimer’s disease is widely reported to be associated with deficits in visual function. Visual disturbances include impaired stereopsis, contrast sensitivity and motion detection. Deficits specific to the magnocellular pathway (MGC) have been identified in Alzheimer’s disease. This article compares the...
Sutureless 27-gauge needle intrascleral intraocular lens implantation
The authors report on a prospective, non-comparative, interventional case series of patients undergoing sutureless intrascleral fixation of a posterior chamber three piece intraocular lens (IOL) using a 27-gauge needle for docking. Sutureless techniques have the advantage of not having complex...
