Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Visual impairment in patients with glaucoma

This retrospective observational study assessed the prevalence of end-of-life visual impairment in patients with glaucoma. A total of 122 deceased patients followed for glaucoma were included and data was collected from patient notes. Sixty-one patients had open-angle glaucoma and 61...

Ocular characteristics in Marfan syndrome

Marfan syndrome (MFS) is a genetic disorder with clinical manifestations associated with cardiovascular, ocular and skeletal organ systems. Typical signs are descending aortic root aneurysms, ectopia lentis, tall stature and scoliosis. This observational study looked at the ocular characteristics, visual...

Glasses or not?

In this excellent review article, the authors discuss how some hyperopes avoid strabismus but also ask why the youngest infants escape strabismus and older patients go on to decompensate. The review considers a number of related aspects and their inter-relations...

Walking with prisms

This study was undertaken to assess which tempero-spatial properties of gait are influenced by vertical yoked prism (VYP) wear and consider any adjustments to gait made to maintain stability both during and following VYP wear. Thirty-one healthy adults were recruited....

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...
