Myopity directly affects learning, the ability to receive and feel life visually, if the disease is severely complications, it can cause retinal degeneration, retinal detachment leading to blindness.
1. What is progressive myopity?
Myopity is the most common type of refractive error today, accounting for about 25% of the total population in the world.
A study by Hanoi Medical University survey of 250 patients aged 5-18 years showed that the highest incidence of myopity was in primary school students, accounting for 55.2%. In addition to genetic causes such as more than 24 genes that are associated with an increased risk of developing myopic vision, the majority of Vietnamese children have vision loss due to sitting in the wrong position when studying, studying intensely, using electronic devices too much and not having the habit of regular eye exams.
Myopity is divided into 3 main groups: mild, near-medium and near-severe. In particular, severe myopopity is distinguished from the other 2 groups of myopity by myopity.)
- Near-light is a person with a near- <=300D (đi-ốp)
- The average person has a close-up of 300 – 600D (cladding)
- Sub-heavy is a person with a near-600D (cladding)
After the age of 18, nearsy-permanent stability, severe progressive myopity is a pathology accompanied by lateral degeneration of the eyeball.
2. Common severe myopopity complications
Most people with myopopeity are only interested in the inconvenience of living, aesthetic problems when wearing glasses … few people know that long-term severe myopity increases the risk of eye disease compared to the average person. Notably, severe progressive myopity can cause many dangerous complications, leading to other eye diseases as follows:
2.1. Visual cons
Asthenia is a visual deterioration caused by the brain's inaction of the image that the eye transmits. Asthenia occurs when myopity is severe and the eye has to regulate too much, the retina does not stimulate to transmit the image signal clearly.
Asthenia can be treated if detected early by eye training when the child is before the age of 12. After the age of 12, whether practicing or having eye surgery, it is still difficult to restore vision 10/10 because the eye has developed steadily as an adult.
2.2. Retinal detachment of the glass
The retina is the nerve membrane at the base of the eye, which plays a role in absorbing light and converting them into nerve signals transmitted to the analytical brain.
People with high myophoids with convex eyeballs forward will pull the retina, making the retinal perimeter thinner and degenerate gradually. If the condition persists, the neurons will lose adhesion and cause more serious complications than tearing, retinal detachment or arterial hemorrhage.
2.3. Outer or alternate
The eye is a condition where the two-eyed homage is not in a balanced position as usual; either side or both will be deviated from the eyeball axis. In high myopic people, poor coordination of regulation of the eye muscles leads to external or rotating spleiding, causing aesthetic loss and vision loss.
Moderate spleidness can be temporarily overcome by wearing glasses suitable for closeness, but if the patient has too high a closeness, does not wear the correct number of glasses, the phenomenon cannot be adjusted.
2.4. Open Angle Glocom
The human eye is progressive to a severe level (above 8 degrees) with a long eyeball axis that stretches layers of optic nerve fibers, making this layer of link thin and weaker. Where the patient has symptoms of market loss corresponding in part to the place of damage on this layer of nerve fibers, it is more likely that the open-angle glocom has been suffered. People with this disease will have a narrowed vision to the center, the image in the corners and surroundings will fade and then lose completely
2.5. Other eye diseases with severe myopopity complications
- Retinal tearing and retinal detachment
3. Advanced myopopity treatments
For the treatment of progressive myopity in children, it is necessary to prevent the on ons rise of myopity and limit the increase in myopity in the child.
3.1. Take low-concentration atropin medications
Atropin is a group of non-selective muscarin antagonist, in the eyes it has effects: dilation of the homies and ticing paralysis; does not cause side effects such as: glare, glare, difficulty seeing near … In addition to controlling increased close-up, low-concentration atropin is also used to control myopeous ons in children.
3.2. Contact lenses, frame glasses
Contact lenses, also known as contact lenses, are a type of medical device that is in direct contact with the surface of the eyeball. Thanks to the effect of reducing blurred images in the retinal area of the perimeter when using some of the following special glasses helps to limit the increase in closeness..
3.3. Conjunctivitis Surgery
Currently, in order to correct rapidly progressing myopity, the most common treatment is still the lasik method. Using specialized tools, the doctor will create a corneal flap and lift it to reveal the lower cornea. This cornea will be affected to change the structure to meet the requirements set, after which the corneal flap will be reset to the old position.
However, this method is only in place for patients over 18 years of age. This is a gentle surgery, with little damage and no significant complications that reduces the degree of progress of myopic disease by almost 3 times.
3.5. Enhance outdoor activities and reduce up close-up time
Many studies abroad show that the group of children who participate in outdoor activities is much lower than the less engaged group of children. In addition, reducing the time for close-up work also contributes to progressive myopic control in children.
4. How to prevent myopity from progressing
- Prevention and prevention of myopity in children should ensure sufficient light when they read or write. Note that the proper light is not too bright or too dim because both adversely affect the eyes.
- Children should keep their eyes reading and writing at least 30cm away. Sit about 50cm away from the computer. Limit reading comics with small or blurry fonts. Children do not eat while reading stories, walking and watching, not lying down to read.
- Eyes need to be rested for a moment, looking away to relax after an hour of reading, watching television. Get an early sleep, get enough sleep, and be on time.
- Proper and adequate nutritional care: vitamin A-C-E, minerals, zinc, selenium … Learning combined with play and extracurricular activities, practicing physical exercise will limit the increase of myopicity.
5. Doctor's advice
Many people think that myopity is a simple refractive error, just wear glasses, but in fact, myopity progresses very quickly if left unexplained, causing degenerative eye disease, vision loss and blindness.
In mild, less advanced cases, children can wear glasses and medical treatment to reduce the level of development of myopic disease and prevent the appearance of bad complications that cause vision loss for the child.
With cases of rapid progress, myopity is increasing, parents should take their children to see a specialist for advice and choose the best treatment.
Concluding, complications when myopity progresses severely are very dangerous, so when you have myopic vision, you should regularly go to the nearest specialist eye hospital to check your myopic condition to find effective treatments in time.
