How common is microbial keratitis in children wearing orthokeratology?

The risk of microbial keratitis (MK) in orthokeratology-wearing children was shown in a 2013 analysis to be around 14 per 10,000 patient wearing years, but new data indicates that it may be lower. Data gathered from a large group of practices in Russia found MK risk of around 5 per 10,000 patient-wearing years, similar to the risk of daily wear soft lenses. This should increase confidence in fitting orthokeratology to children for myopia control.

Five year cumulative incidence of myopic maculopathy in Germany

This study utilized data from over 15,000 participants aged 35-74 years and found a five-year cumulative incidence (new onset) of myopic maculopathy in the general population of 3 in 1,000. In 509 eyes with over 6D of myopia, 7% had myopic maculopathy and of these 50% worsened over the study period.

Axial length and reduced macular sensitivity before changes in acuity

This study showed that adult high myopes with myopic macular degeneration (MMD) show reduced macular sensitivity as measured by microperimetry. That’s not unexpected; but the microperimetry changes occurred before BCVA changes in mild MMD – read more here.
