Flicker‐defined form stimuli are minimally affected by centre‐surround lateral contrast interactions
ConclusionFDF stimuli necessarily have both flickering target and background. Our results suggest that visual field defects outside the target are unlikely to markedly influence the detection and perception of the FDF stimulus. Nevertheless, mild surround suppression of contrast arises for FDF stimuli, hence interactions between the background and the target area may influence FDF results in conditions that alter centre‐surround perceptual effects.

Longitudinal imaging of microvascular remodelling in proliferative diabetic retinopathy using adaptive optics scanning light ophthalmoscopy
ConclusionsHigh‐resolution serial AOSLO imaging enables in vivo observation of vasculopathic changes seen in diabetes mellitus. The implications of this methodology are significant, providing the opportunity for studying the dynamics of the pathological process, as well as the possibility of identifying highly sensitive and non‐invasive biomarkers of end organ damage and response to treatment.

Comparison of Heidelberg Retina Tomograph with disc‐macula distance to disc diameter ratio in diagnosing optic nerve hypoplasia
ConclusionsBoth HRT and the DM:DD ratio are valid tests to aid diagnosis of CONH. HRT is superior to DM:DD ratio in diagnosing CONH with higher sensitivity and specificity. We suggest the optimal cut‐off value for HRT disc area as 1.42 mm2 in order to discriminate a hypoplastic disc from a normal optic disc. (Source: Ophthalmic and Physiological Optics)

Do small‐aperture presbyopic corrections influence the visual field?
ConclusionThe present theoretical and experimental results support earlier clinical findings that KAMRA‐type annular stops, unlike circular artificial pupils, have only minor effects on measurements of the visual field. (Source: Ophthalmic and Physiological Optics)

Accommodative movements of the lens/capsule and the strand that extends between the posterior vitreous zonule insertion zone & the lens equator, in relation to the vitreous face and aging
ConclusionsThe accommodative shape change of the central capsule may be due to the elastic properties of the capsule itself. For these capsule/lens accommodative posterior movements to occur, the vitreous face must either allow for it or facilitate it. The PVZ INS‐LE structure may act as a ‘strut’ to the posterior lens equator (pushing the lens equator forward) and thereby facilitate accommodative forward lens equator movement and lens thickening. The age‐related posterior restriction of the ciliary muscle, vitreous zonule and the PVZ‐INS LE structure dampens the accommodative lens shape change. Future descriptio...

Retinal thickness profile of individuals with diabetes
ConclusionThe inner macula is thinner in the presence of clinical signs of diabetic retinopathy and is compounded by advancing age. The influence of any macular oedema or that by cotton‐wool spots could not be ruled out and may still confound these results. (Source: Ophthalmic and Physiological Optics)

Miniscleral lens wear influences corneal curvature and optics
ConclusionsMiniscleral contact lenses that vault the cornea induce significant changes in anterior corneal surface topography and higher order aberrations following 8 h of lens wear. The region of greatest corneal flattening was observed in the superior‐nasal mid‐periphery, more so in East Asian participants. Practitioners should be aware that corneal measurements obtained following miniscleral lens removal may mask underlying corneal steepening. (Source: Ophthalmic and Physiological Optics)

Strategies for the prevention of contact lens‐related Acanthamoeba keratitis: a review
Abstract PurposeAcanthamoeba keratitis is a severe, often sight threatening, corneal infection which in Western countries is predominantly seen in daily wear of contact lenses. This review aims to summarise the pathobiology and epidemiology of contact lens‐related Acanthamoeba keratitis, and to present strategies for prevention, particularly with respect to modifiable risk factors in contact lens wear. Recent FindingsThe virulence of Acanthamoeba and resistance to treatment in keratitis appears to be linked with the production of a low molecular weight protease MIP133 by the organism, in response to binding to corneal ep...

Google Glass Glare: disability glare produced by a head‐mounted visual display
ConclusionsHead mounted displays such as Google Glass have the potential to cause significant disability glare in the eye exposed to the visual display, particularly under conditions of low luminance. They can also cause a more modest binocular reduction in sensitivity by eliminating the benefits of binocular summation. (Source: Ophthalmic and Physiological Optics)
