Effect of intravenous mannitol in post vitrectomised eyes

The purpose of the study was to evaluate the effect of intravenous mannitol 20% on intraocular pressure in vitrectomised silicone-oil filled eyes. A prospective analysis of consecutive patients was undertaken with their fellow eyes taken as controls. Thirty-one patients were...

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...

Childhood headaches

The goal of this study was to compare headache resolution in children receiving or not receiving refractive correction. The authors conducted a retrospective review of 158 patients: 78 male and 80 female aged three to twelve years (mean eight). Twenty-seven...

Long-term open angle glaucoma cohort study

This was a study to estimate the development of open angle glaucoma (OAG) in a screened and re-examined elderly group as compared to an unscreened group during the same time period. The participants comprised of 856 individuals born in 1915...

DTI/MRI results in amblyopia

Diffusion tensor imaging (DTI) is an MRI technique that can evaluate white matter integrity and neuronal connectivity. Normal brain maturation and myelination are associated with reduced water diffusion and increased diffusion anisotropy. The authors aimed to evaluate the anterior optic...

An unusual case of sellar chondroma

A single case of chondrogenic neoplasm arising from the base of the skull is presented and discussed. These benign and slow growing tumours in the sellar region are extremely rare and as such this article provides a useful insight and...

Extraocular muscle BT after ocular pathology

Management is described for 13 patients who received inferior rectus botulinum toxin (BT) injection for vertical strabismus due to orbital pathology. Patients were aged 19-86 years, eight were female and seven were right eye injections. Orbital pathology included six with...

Long-term outcomes following surgery for traumatic cyclodialysis clefts

This retrospective case series evaluated the long-term visual prognosis and intraocular pressure control following surgical treatment of traumatic cyclodialysis clefts. Cyclodialysis clefts result from the disinsertion of the longitudinal ciliary muscle fibres from the scleral spur and occur as a...

Association between neuro-ophthalmology signs and chronic ataxia in children

Neuro-ophthalmological signs (N-OS) occur commonly in children with chronic ataxia. This study describes the N-OS and their frequencies, in general and by specific disease aetiology in paediatric patients with chronic ataxia. In total, 184 patients under the age of 17...

Nanoparticle administration of latanoprost

Glaucoma is a progressive optic neuropathy characterised by increased ocular pressure and loss of retinal ganglion cells. Conventional drug therapy with eye drops to reduce intraocular pressure (IOP) has variable bioavailability and can lead to ocular surface disease. In this...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma

Lens subluxation can be caused by many conditions including Marfan syndrome and other hereditary conditions, and blunt trauma. Lens displacement can cause pupillary block and angle closure. This is commonly misdiagnosed as primary angle closure glaucoma (PACG), which can lead...
