What is anisometropia?
Myopia (short-sightedness) is a refraction issue whereby objects in the distance focus in front of the retina and not on it. This makes these objects seem blurred. It usually happens in infancy and evolve into adulthood.
It happens because the eye is too long and the cornea has more curvature than normal or the crystalline lens is too powerful.
The WHO predicts that fifty percent of the world population will have myopia by 2050.
There are various factors causing this issue, including:
The symptoms of myopia may include headache, tiredness, forcing the eyes to see properly and problems focusing on objects in the distance.
It begins in childhood and usually progresses into adulthood.
When it comes to children, we should be aware of certain symptoms as myopia tends to manifest itself during the school years:
Treatment for myopia should be tailored to suit each individual case, and although it cannot be cured, it can be corrected through:
Laser refractive surgery is the most commonly used technique to correct myopia.
Frequently asked questions
In myopia (short-sightedness), there's an imbalance between the eye's visual system and its length. It can happen either because the cornea or crystalline lens has too much dioptric power or because the eye is excessively long, hence the myopia increases when the eye increases in size with the growth. These changes may be determined by genetic or hereditary factors among others.
We should suspect that a child has myopia when they can't see the board or television propertly, when they move really close to see objects, or when they squint to see far away.
