Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...

Comparison of false-negative responses in glaucoma patients and normal observers

The authors compared false negative rates for full threshold (FULL) and Swedish Interactive Threshold Algorithm (SITA) standard automated perimetry in healthy control subjects and glaucoma patients. Twenty-four subjects underwent visual field testing of one eye five times within six weeks...

PD-1 and PD-L1 in exenteration specimens

This is an immunohistochemical study looking at variation in the expression of the programmed death-1 receptor (PD-1) and the programmed cell death ligand-1 (PD-L1), comparing cutaneous malignancies which invaded the orbit with uncomplicated nodular basal cell carcinomas. The authors retrospectively...

Sleep positions and the effect on IOP

The authors describe a study to determine if sleeping at a 20 degree head up position decreases nocturnal IOP compared with lying supine in patients with and without glaucoma. They recruited 30 patients (60 eyes) 15 with glaucoma and 15...

Randomised trial of multifocal intraocular lens versus monovision

The authors report on a randomised, multicentre clinical trial comparing the outcomes of Tecnis ZM900 diffractive multifocal intraocular lenses (IOL) versus monovision with Akreos AO monofocal IOL (dominant eye targeted for emmetropia and non-dominant eye targeted for -1 to -1.50...

Does breastfeeding protect against age-related cataract?

This nationwide cross-sectional study is the first of its kind assessing the relationship between breastfeeding and maternal age-related cataract in Korea. They assessed the participants into quartiles depending on the number of breastfed children and duration of breastfeeding. There were...

The impact of collagen crosslinking on keratoplasty numbers in keratoconics

A question of corneal cross-linking (CXL) reducing keratoplasty numbers in keratoconics was addressed in this single centre observational study from the Oslo University Hospital – a sole provider of keratoplasties and CXL for a population of 2.8 million. Authors compared...

Selection of visual field test for detection of pituitary disease

This prospective cross-sectional diagnostic accuracy study compared Octopus semi-automated kinetic perimetry (SKP) and Humphrey static automated central perimetry for detection of neurological visual field loss in patients with pituitary disease. Humphrey central 30-2 SITA threshold programme results were compared with...

Saccadic differences under cover test

Patients with intermittent exotropia and exophoria plus ortho subjects underwent measurement of saccadic reaction times (SRTs) to compare those occurring in one eye and those occurring with alternating cover tests (ACTs). Twenty-five subjects were studied. Results for the intermittent exotropia...

Prediction of visual outcome in IIH

In this prospective study, visual outcome of 40 patients with idiopathic intracranial hypertension (IIH) was compared with clinical and neuro-ophthalmic parameters. The purpose of this was to determine any correlation to try and predict visual outcome for IIH patients. Parameters...

Investigation of blood platelet parameters in anterior ischaemic optic neuropathy

The aim of this clinical retrospective comparative study was to assess the possible relationship between arteritic anterior ischaemic optic neuropathy (AAION) and non-arteritic anterior ischaemic optic neuropathy (NAION) with blood platelet parameters and neutrophil-to-lymphocyte ratio (NLR). The medical records of...

Persistent anterior uveitis after cataract surgery

This retrospective cohort study was completed to help identify potential risk factors for developing persistent anterior uveitis (PAU) following uncomplicated cataract surgery in patients with no prior history of uveitis or autoimmune disease. A total of 3013 eyes (2019 patients)...
