Miopa
Makes years that the scientists treated with little success in achieving a method capable of slowing the progression of the miopa. Now, a study published in the magazine ‘Archives of Ophthalmology’ suggests that the kids with this problem may benefit from the use of glasses bifocal. Although the authors of the research are cautious and does not seem to its conclusions are to have immediate implications.
As explains to ELMUNDO.is dr. Rosario GOMEZ the Hospital clinical San Carlos de Madrid, “this study is preceded by many other investigations that have suggested otherwise”, so that everything indicates that the science continues to cast promising results but you do not conclusive on how to curb the loss of vision of far away.
In this at, researchers at the university australian selected Brisbane to 131 kids of Asian origin¡tico with an average of age of 10 years and three diopters (and whose loss of vision had grown at least half diopters in the last year). During three years and with reviews every six months, divided into three groups: those that wore glasses normal, which used some bifocals (to see both far as closely) and a third group with bifocals with prism (a type of lens that corrects a true strabismus latent in the short-sighted).
The small os who used the glasses bifocal (both with prism as without IT (l) saw how they are brake the progression of his miopà of a way more significant than the kids who used the lenses conventional. Specifically, the last had an increase of 1.55 diopters, as in the period of study compared to 0.96 and 0.77 of the who used bifocals and bifocal with prism respectively.
Despite the profit is not a very significant, as explained Juan Enrique Corral, a member of the Association n Spain wave of Optometrists, “and there will be to assess the trauma are©tico that can pose to the kids carry the glasses of the elderly.”
An old remedy
Only in the countries of this Asian¡tico is estimated that half of the kids is short-sighted before reaching the 12 years and they suspect that this percentage can be very similar to the rest of countries developed. That is why suggest that, if confirmed his theory, the use of glasses bifocal may benefit a significant number of kids around the world.
Although as themselves recognize, is soon to generalize its conclusions (studies are needed more extensive and with a follow-up to more long-term) and you are many things that remain unknown on this defect that ‘blurred’ the vision from afar. “Today we do not know why, for example, in the case of two brothers with living conditions similar to one it increases the miopà and another not,” explains Dr. Gomez of Lia, president of the European companies and Spain wave of strabismus.
Specifically, the use of bifocals to correct the defect “wore years parked”, and in spite of these new conclusions you do not know what happen with the small study if change of lenses after three years of study. While the mysteries of the miopà to remain unresolved, the experts recommend to the parents of these kids (whom more concerned that the diopters, as continue to grow year after year) not to abuse activities requiring endeavor much light as the reading, the computer or video games, which may favor the increase of diopters, as in the small predisposed.
