If the extent of the myopia is great enough, even standard reading distances can be affected. Upon routine examination of the eyes, the vast majority of myopic eyes appear structurally identical to non-myopic eyes. In cases of high myopia, a staphyloma can sometimes be seen on fundoscopic examination.
It removes need for glasses; reducing 'near work', going outdoors slow myopia progress Mr A Myopia in singapore an unusual patient. I had just completed an operation and was walking into my clinic when a boyish-looking man dressed in office attire stood up and followed me from the lift lobby into my consultation room.
There was a look of trepidation on his face and his brows were knitted with worry. Even before I could sit down, he started telling me there was a shadow in his field of vision that would not go away and that he had been experiencing it since that morning.
It was a good thing he sought help: He had a retinal detachment and needed urgent surgery on the same day. When I broke the news to him, his initial reaction was quite out of the ordinary.
Instead of asking about the operation procedure and its risks and benefits, his first question was when he could return to work after the surgery. I found out later that he was a high-flying investment banker. I told him that his eye condition was likely due to his high myopia, or Myopia in singapore.
He replied with complete disbelief: However, the edges of the cornea flaps, created during the Lasik procedure, was a giveaway when I examined his eyes. The examination of the back of his eyes the retina also revealed thinned-out layers, which was consistent with high myopia.
He said he had to wear glasses with thick lenses of about 1, degrees each before his Lasik surgery. A week prior to the shadow appearing in his field of vision, Mr A saw "flashing lights", little spots and cobweb-like structures.
These are warning symptoms of a retinal problem, which could indicate a retina tear or detachment. Mr A went on to have an uneventful surgery to repair his detached retina, and was up and about in his office two weeks later.
He was fortunate to have sought medical treatment early enough - before the detachment affected the central part of his retina. Otherwise, the visual symptoms would have been worse. Instead of a shadow seen in the peripheral field of vision, he would have experienced blurred vision.
Some patients have even described it as having a "curtain coming down" in front of their eyes. At that stage, the chances of recovering one's vision, even after surgery, may be reduced.
Patients with high myopia of more than degrees, like Mr A, are at higher risk of serious and potentially blinding conditions.
These include retina tears and detachments, bleeding under the retina and low-pressure glaucoma. There are many misconceptions that Lasik is a cure for myopia. In fact, Lasik and other refractive procedures, such as implantable contact lenses, merely remove the need for spectacles or the dependence on external contact lenses.
The internal structure of the eye remains unchanged. A thinned-out retina from high myopia will remain just as thin after Lasik surgery and other refractive procedures.
Hence, the risks of eye conditions associated with myopia will remain, even after Lasik surgery. Singapore is the myopia capital of the world as it has the highest prevalence rate of this eye condition.
Studies have shown that one in three five-year-olds in Singapore is myopic, and this figure increases to an alarming 80 per cent in year-olds.
Genetic and environmental factors play a role in the myopia affecting Asians, especially Chinese.
The main environmental factor associated with myopia progression is "near work" - which includes prolonged reading and computer usage - and a lack of outdoor activity With today's rapid advancement in information technology, it is not unusual to see youngsters glued to their smartphones or tablets.
The emphasis on schoolwork in our education system may also reduce the time children spend outdoors. Some children simply love to read. One exasperated mother once told me that her son would hide in the toilet to read his storybooks. She could not stop him from reading. For this child, who had myopia of degrees at 10 years old, I prescribed an eye drop that could retard myopia progression.
Whether a child should be prescribed such eye drops depends on his age, his parents' preference and the degree of myopia. Myopia usually continues to worsen until a child stops growing.
Scientific studies have yet to confirm the exact mechanism of how this works.
However, recently published studies postulate that the eyedrops act on certain growth receptors on the sclera white coat of the eye to retard its rapid expansion and hence reduce myopia progression.
The child is now 14 and I am happy to say that his myopia has remained stable at degrees.“In our experience, children with myopia add an average of D per year if concrete measures are not being taken,” says Xu.
