CLINICAL & RESEARCH INFORMATION FOR THE EYECARE PROFESSIONAL

Vision Research Institute Myopia Awareness Survey

In a survey carried out by the Vision Research Institute (VRI) at the Michigan College of Optometry, Ferris State University, over 700 eye care professionals from all over the world were asked about their preferred method(s) to control the progression of myopia in a clinical setting.  Click here for a full summary of results of the Myopia Awareness Survey. 

HOW DO YOU CONTROL MYOPIA?

Corneal Reshaping

Despite the heightened interest in Orthokeratology (OK) in recent years, it is not a newly developed phenomenon.  Otherwise known as Corneal Reshaping in its modern day form, this process of using gas permeable contact lenses to temporarily alter the structure of the corneal surface dates back to over a century ago.

Spectacles

There is a large body of research that has accumulated over the last century pertaining to myopia and defocus in an attempt to uncover what exactly is the association between the two.  In doing so, a series of hypotheses regarding potential environmental triggers have surfaced and subsequently resulted in the development of various treatment modalities.  Several types of spectacle corrections have been explored as possible forms of myopia control.

Soft Contact Lenses

There has been a recent rise in research initiatives applying the theoretical principles of retinal defocus beyond the fovea.  Both human and animal studies carried out by groups such as Mutti, Zadnik et al and Smith et al, respectively, shed light on the refractive nature of the peripheral retina and its potential impact on myopia development.  Several subsequent studies have given rise to a growing body of scientific knowledge that has prompted novel clinical applications.

Pharmaceuticals

Myopia Control Pharmaceutical Methods

With the long established theory of reading and excess near work playing a role on myopia progression due to their close association to accommodation, several research initiatives have been directed towards eliminating this trigger.  Various topical muscarinic antagonists have been investigated for their cycloplegic effect to minimize accommodative dysfunction as a stimulus to myopic development.

Lifestyle Changes

Myopia Control Lifestyle Changes Methods

A very recent theory has surfaced linking the amount of time spent outdoors as a potential myopigenic trigger.  A study carried out by Jones et al, 2007, showed that children who had increased participation in outside activities exhibited a reduction in myopia progression versus their less active counterparts.  The Sydney Myopia Study (Rose et al, 2008) also found a protective effect from greater amounts of exposure to outdoor lighting.  It is hypothesized that light intensity may play a role.

Undercorrection

Myopia Control Undercorrection Methods

It has been long theorized that deliberately limiting a full myopic prescription may serve to reduce the progression of myopia.  If myopic defocus on the retina is the result of such a practice, then ideally there should be a decreased accommodative demand at near and less of a stimulus for axial elongation.  Studies carried out by Chung et al, 2002, and Aller et al, 2006​, have actually shown that using this method of myopia control has actually led to an increase in myopia progression.  It is possible that central myopic retinal defocus is not a protective factor against the development of myopia.
