Modified technique in place of ultrasound biomicroscopy

The authors describe a modified immersion B-scan ultrasonography that includes a standard B scan probe of 10MHz, a surgical glove and sterile saline to fill a finger of the surgical glove – tied off to create the desired immersion standoff...

Risk factors for DSEAK graft detachment

This was a retrospective data review on all patients who underwent primary descemet stripping automated endothelial keratoplasty (DSEAK) during a 10 year period: 1212 eyes were included in the analysis. Postoperative graft detachment occurred in 45 eyes (3.7%) and required...

Trabeculectomy ab interno (trabectome)

This retrospective study examines the outcome of trabectome surgery in nine phakic patients with Posner-Schlossman syndrome with uncontrolled IOP >30mmgHg. Cytomegalovirus (CMV) DNA was verified by polymerase chain reaction (PCR) in aqueous humour samples. Patients were treated with oral valganciclover...

RPTP-σ increases pro-MMP activity in a trabecular meshwork cell line following oxidative stress conditions

This study aims to outline the role of phosphatases in the aqueous drainage system by overexpressing receptor tyrosine phosphatase sigma (RPTP-σ) in a human normal trabecular meshwork cell line and describing its effect on subtypes of matrix metalloproteinases (MMP) and...

Cytotoxic effect of voriconazole on human corneal epithelial cells

Voriconazole is a second-generation synthetic derivative of fluconazole with broadened antifungal spectrum. It is becoming the drug of choice for fungal keratitis. Voriconazole eye drops are not available commercially, thus have to be prepared by diluting the intravenous formulation containing...

Sustained elevation of extracellular ATP in chronic glaucoma

Although adenosine 5′-triphosphate (ATP) release from retinal neurons and astrocytes has been demonstrated in short-term increases in intraocular pressure (IOP); such as in aqueous humor of humans with primary acute angle closure glaucoma, the response in chronic IOP elevation was...

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...

VEGF and axial length (RVU)

The authors of this paper set out to examine whether the concentrations of VEGF in the vitreous were associated with refractive error and axial length in eyes without retinal disease, except of macular holes or epiretinal membranes. A vitreous sample...

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

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...

Minimally Invasive Glaucoma Surgery: What options are there and when might they be considered?

In recent years there has been a rapid expansion in a group of operations termed ‘minimally invasive’ or ‘micro invasive’ glaucoma surgery (MIGS). These options generally offer less significant IOP reduction, but with a more favourable safety profile when compared...

The approach to trabeculectomy postoperative complications

Performing a trabeculectomy is like giving birth to a baby. It may be traumatic and there is scope for devastating error but once the operation is completed only then does the real work begin. The bleb must be nurtured into...
