Rise of myopia in children poses health risks

An alarming rise in myopia among children raises long term health issues

Increasing awareness of the alarming rise in myopia among children – described as an ‘epidemic’ in some quarters – raises long-term health issues.

The recent paper by Ian Flitcroft of the Children’s University Hospital, Dublin, reported on the effect of myopia in relation to glaucoma and retinal detachment: ‘Myopia represents a major risk factor for ocular disease that is comparable with the risks associated with hypertension for cardiovascular disease. The myopia risks for glaucoma and cataract were also comparable with the risks of stroke from smoking 20 cigarettes per day.

‘For retinal detachment and myopic maculopathy, myopia carries a risk far in excess of any identified population risk factor for cardiovascular disease.’

It was previously thought that the risk of eye health issues was highest in people with prescriptions higher than -6.00D, but even 1-3D of myopia increases the risk of retinal detachment fourfold. Up to -3.00D there is a two-fold increase in the risk of developing glaucoma, and any reduction in myopia is beneficial in all respects.

As we expect a comprehensive immunisation programme to guard against a host of diseases – statins to protect against the effects of raised cholesterol and orthodontic treatment to correct overcrowded teeth and reduce the risk of decay – should myopia control be viewed in the same light?

A series of recent studies from respected authorities around the world demonstrate the benefit of ortho-k in controlling the progression of myopia.

This modality of vision correction should be viewed as a valuable tool in reducing costly eye health treatment in future years.

Now is the time to discuss early intervention as a ‘stitch in time can surely save nine’ in terms of NHS funding.
