Differential diagnosis of inflammatory optic neuritis

The authors present the differential diagnosis of inflammatory optic neuritis (ON) to include multiple sclerosis, infectious optic neuritis, systemic disease and neuromyelitis optica (NMO). The features of ON for the varying aetiologies are detailed including incidence and overlap. In acute...

Scheimpflug vs. OCT in measuring corneal thickness

The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...

Translucent vs. lightproof occluders

This study investigates the change in visual acuity following occlusion in amblyopes and non-amblyopes using translucent versus lightproof occlusion of the dominant eye. Group 1 non-amblyopes consisted of 26 subjects: 16 visually normal and 10 strabismic or anisometropic subjects without...

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...

Photoscreening comparison

The A09/S09 photoscreener contains a fixation target of flashing lights (as for the S04) plus a smiley face which is new. Concerns were raised that the smiley face may stimulate less accommodation than the S04 attention lights and therefore potentially...

HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...

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...

Oral proton pump inhibitors in macular degeneration patients

The authors report five patients with advanced wet macular degeneration and poor vision with onset or enhancement of visual hallucinations with the use of proton pump inhibitors for heartburn management. The hallucinations were reversible with discontinuation of medication. The authors...

Corneal biomechanics and refractive outcomes after cataract surgery

The authors aimed to study a range of corneal properties and correlate them with refractive outcomes after phacoemulsification. Outcomes were reviewed in a fairly small group of 40 patients (including only right eyes) operated by two surgeons using clear corneal...

Baerveldt Glaucoma Implant (BGI)

The authors describe surgical outcomes using the BGI and compared the different techniques used. The main differences described in the implantation technique include the use of a prolene stent in the tube, or fixation of the tube to the sclera....

Swept source anterior segment OCT

The authors describe a study using the Casia OCT which is a swept source OCT to determine the visibility of the angle structures using two imaging protocols; high density and low density. They randomly selected one eye from 30 normal...

Effects of clonidine vs. placebo

The purpose of this study was to measure postoperative agitation using a standardised scale and evaluate whether it is reduced if given clonidine prior to strabismus surgery as compared to placebo. The scales included the Pediatric Anesthesia Emergence Delirium (PAED)...
