Facilitators and barriers to conducting research

A survey of clinicians and researchers across the UK was conducted to identify barriers to research and potential solutions. The authors extracted details of studies listed on the UKCRN database that involved paediatric ophthalmology with recruitment of children. An e-survey...

Micropulse vs. continuous wave trans scleral diode cyclophotocoagulation in refractory glaucoma

Continuous wave cyclophotocoagulation (CWCPC) delivers continuous high intensity energy to the ciliary body in an attempt to reduce aqueous secretion and hence lower IOP. It is often used as a treatment of last resort due to the potential side-effects of...

Effect of topical diclofenac on postoperative PRK pain: RCT

A major disadvantage of excimer laser photorefractive keratectomy (PRK) is pain and discomfort after the surgery, which is thought to be due to damage to corneal sensory nerve fibres or local release of inflammatory substances. Pain only resolves once corneal...

Superior oblique muscle tuck

The authors investigate the efficacy and safety of isolated superior oblique tucking in patients with congenital superior oblique palsy. The study includes 21 cases: eight females and 13 males aged 2-34 years. All had obvious superior oblique under action and...

Glaucoma prevalence in sleep apnoea

Obstructive sleep apnoea (OSA) is a disorder characterised by brief interruptions of breathing during sleep and results from complete or partial collapse of the pharyngeal airway. This study investigated the prevalence and progression of glaucoma in 39 patients receiving treatment...

Imaging and histological relationship of orbital Schwannomas

This is a retrospective review of 15 patients with orbital Schwannomas comparing the radiological characteristics, in particular the signal intensity on MRI, with the histological sub-types of the tumours. Five patients had MRI imaging alone, three had CT alone and...

Meta-analysis of HLA B27 associated acute anterior uveitis

A literature-based meta-analysis was carried out to look at the various clinical features associated with HLA- B27 acute anterior uveitis (AAU). After an extensive search of literature for HLA B27 uveitis was conducted, 735 results were obtained. Twenty-nine articles were...

Relationship between nocturnal intraocular pressure elevation and diurnal intraocular pressure level in NTG patients

This group studies Korean normo-tension glaucoma (NTG) patients over a 24-hour period to assess if there was a relationship between nocturnal intraocular pressure (IOP) and diurnal IOP. They have previously suggested differences in diurnal IOP may have varying mechanisms of...

Long-term effect of gene therapy on Leber’s congenital amaurosis

After reporting the first successful gene therapy results for RPE65 deficiency in three patients in a brief report in 2008, the same team from London now report the results of 12 patients followed up for three years after transfection. As...

Four year outcomes of macular degeneration treated with ranibizumab

The authors report on a retrospective study of neovascular age-related macular degeneration (AMD) patients treated with a variable ranibizumab dosing regimen over a period of four years (from January 2007 to December 2011). A total of 600 treatment naïve eyes...

Endoscopic assisted probing for congenital nasolacrimal duct obstruction

In this retrospective study authors compare the success rate of nasal endoscopic-assisted probing between younger (three years and below) and older (three years and above) children with membranous nasolacrimal duct obstruction and its correlation with the thickness of the membrane...

Metamorphopsia in idiopathic epiretinal membranes

The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...
