Myopia
The work of Earl Smith III in investigating the influences on axial length growth in mammals has been key in many of the recent developments in myopia control research. In delivering the Charles Prentice Lecture he described much of this research over recent years and (pardon the pun) shed light on new findings suggesting light exposure as a key component in eye growth. He began by arguing the case for peripheral vision treatment strategies for myopic control. He had shown in animal models that manipulation of the peripheral image to bring it closer to the retina from a hyperopic shell significantly reduced axial length growth. Furthermore, there must be growth mechanisms involved at the retinal level as these growth changes still occur even when the higher pathway connections are severed. 'Peripheral treatment strategies are important,' he established, with reports of a 49 per cent reduction in myopia and axial length being established with contact lens manipulation of the peripheral focal shell.
