The Leicester Grading System for Foveal Hypoplasia
The University of Leicester Ulverscroft Eye Unit have published the first medical grading system named after the city of Leicester. Infantile nystagmus is characterised by constant and involuntary eye movements and affects 24 per 10,000 people [1]. Onset is usually...Trans-sinus endoscopic removal of retrobulbar air gun pellet within the orbital apex
Injuries to the eye have been widely reported in medical literature due to a variety of mechanisms causing significant morbidity and occasional unexpected mortality for the patient [1]. It is often wrongly assumed that air gun pellets lack this potential....
Revision of orbital fracture repairs
This is a retrospective review of 13 patients with sub-optimal outcomes following primary orbital fracture repairs who underwent revision surgery. All had fractures of the orbital floor, with four involving other orbital walls, and six also involving other facial bones....
Non-arteritic anterior ischaemic optic neuropathy in the Asian population
This article provides an evaluation of changes in visual function associated with non-arteritic anterior ischaemic optic neuropathy (NAION) among Korean patients. Visual changes were identified as a reduction in visual acuity by three Snellen lines or a deterioration of visual...
G-CSF intravitreal injections for NAION: a pilot study
In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...
Leber’s hereditary optic neuropathy outcomes in an Indian population
A large cohort study in an Indian population is presented, with clinical and genetic profile analysis of patients with Leber’s hereditary optic neuropathy (LHON) treated over a five-year period. The study included 157 patients; 143 male, 14 female (10.2:1 ratio)...
Variability between handheld fundus cameras
Handheld fundus cameras offer the potential of enhancing opportunities for telemedicine diagnosis of glaucoma, especially in underserved settings, as they are less bulky, inexpensive and don’t require skilled personnel compared to traditional table-mounted retinal cameras. This study aimed to compare...
Features of bacterial orbital cellulitis on MRI imaging
This multi-centre retrospective study from Australia and the UK examined the quantitative and qualitive parameters of magnetic resonance imaging (MRI) imaging in bacterial orbital cellulitis. Twenty MRI scans from 20 patients with pre-septal and orbital fat involvement (mean age: 40.8...
What plane should be used for ultrasound measurement of the optic nerve sheath diameter?
This prospective observational study aimed to evaluate the differences between optic nerve sheath diameter (ONSD) between the patients’ two eyes and different ultrasound planes (transverse and sagittal). Participants were recruited over a two-year period from a single neurosurgical department. To...
