He maintains strong links with academia as a visiting lecturer at Aston, and is continuing his research by exploring the effect of peripheral defocus on axial growth
and modulation of refractive error in hyperopes.
It has been hypothesized that a high near-accommodation lag induces abnormal axial growth
of the eye, though many studies have not found an association between accommodation and myopic progression.
Bracing and physical therapy have not been particularly successful at halting progression, and spinal fusion procedures can cause limitations on the space available for the lungs, as well as the axial growth
of the spine and ultimately, the height of the patient.
We noted that the growth of the peripheral skeleton of moose prevails over axial growth
during development of the fetus but after birth this pattern reverses.
A complex interaction of many messengers in a locally-regulated growth pathway seems to be the most likely explanation for the excessive axial growth
which occurs in experimentally-induced myopia and potentially in human myopia.
lobata and endolithic fungi as described from the island of Moorea, in the eastern Pacific (7), and Mayotte, in the western Indian Ocean (13) exists in other corals, and if so, whether endolithic microboring fungi are able to keep pace with skeletal accretion rates and to interact with corals that exhibit rapid axial growth. The corals selected for study were Pocillopora eydouxi and Acropora cytherea.
lobata (7, 13), also occurs in corals with rapid axial growth. In addition, we extend evidence of this phenomenon to a second and third family of important reef-building corals, the Acroporidae and the Pocilloporidae.
The AOP's head of education, Dr Ian Beasley (pictured), and senior optometry lecturer at Aston University, Dr Nicola Logan, will present The positive and negative sides to axial growth
Should we consider the possibility of being able to encourage axial growth
in this cohort?
(22,23) Similar to orthokeratology, the use of a multifocal contact lens alters the peripheral image shell thus reducing the relative peripheral hyperopic defocus thought to be influential in axial growth
. Recent data published from a three-year randomised double-masked clinical trial involving 144 children aged eight to 12 years, found that the dual-focus contact lens was able to slow myopia progression by 59% and axial elongation by 52%.23 This follows a previous randomised contralateral eye study within a similar age group which found that in the multifocal wearing eye, 70% of children had a reduction in myopia progression of 30% or more.
