Reported cases of hemifield slide phenomenon
This article reports three cases of hemifield slide, a phenomenon whereby there is an inability to stabilise and fuse visual hemifields. It occurs with heteronymous visual field loss and is thought to result from the loss of corresponding retinal points....Acute management of retrobulbar haemorrhage
The authors discuss the importance of rapid diagnosis and correct management of acute RBH presentation to avoid the risk of permanent blindness. Retrobulbar haemorrhage (RBH) is an ocular emergency that occurs due to arterial bleeding in the orbital cavity behind...
Silicone oil in rhegmatogenous retinal detachment
Silicone oil (SO), used in complicated retinal detachments, is associated with complications such as cataract, increased intraocular pressure (IOP), keratopathy, cystoid macular oedema (CMO), epiretinal membrane (ERM) and loss of vision. Emulsification of oil can also lead to migration of...
Brn3b neuroprotective effect in rat glaucoma model
An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...
Outcomes of chemo versus no therapy for optic pathway glioma in NF1
The aim of this study was to evaluate the visual outcomes of a cohort of children with optic pathway gliomas and neurofibromatosis type 1 (NF1), with comparison of children treated with chemotherapy or not. This was a retrospective study of...
Visual outcomes and predictors in optic pathway glioma
This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...
Using bupivacaine to the medical rectus in addition to lateral rectus recession for convergence insufficiency type intermittent exotropia
This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...
Orbital Schwannomas
This is a large case series of orbital Schwannomas managed at a single centre over a 26-year period. Twenty Schwannomas are reported, all but one of which was managed surgically. The tumours were all benign, had an insidious onset and...The management of possibly progressive pterygium
A 43-year-old Sudanese male patient is referred by his GP with a fleshy lesion encroaching the nasal cornea for the last six months. History Make note of: risk factors, i.e. UV exposure and ocular irritation - history of living in...
Complications with porous orbital implant after enucleation in retinoblastoma patients
This is a retrospective, case control study aimed to identify risk factors associated with complications in retinoblastoma patients following primary and secondary enucleations with porous implant placements. Patients with retinoblastoma who underwent enucleation with porous orbital implant placement between January...The interpretation and use of ultrasound biomicroscopy (part 1)
Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...
