Role of the Genetic Factors in the Development of Myopia
Myopia, also known as nearsightedness, is the most common eye disorder worldwide. In myopic peoples, the image of distant objects falls in front of the retina, either as the eye is too long (axial myopia), the cornea is too convex or the index of refraction of the lens is too high (refractive myopia). The light enteringthe eye is not focused correctly and distant ob‐ jects look blurred [1]. The...

متن کاملHow genetic is school myopia?
Myopia is of diverse aetiology. A small proportion of myopia is clearly familial, generally early in onset and of high level, with defined chromosomal localisations and in some cases, causal genetic mutations. However, in economically developed societies, most myopia appears during childhood, particularly during the school years. The chromosomal localisations characterised so far for high famil...
متن کاملEffects of Various Risk Factors on Myopia Progression
Background: Myopia has different prevalence rate worldwide and there is controversial points about its environmental risk factors. The prevalence of myopia in medical interns atShirazMedicalSchool and its probable risk factors were studied. Method: In this retrospective cross-sectional study, three hundred interns (7th-year medical students) at Shiraz University of Medical Sciences were examine...
متن کاملEvaluation of proteoglycan gene polymorphisms as risk factors in the genetic susceptibility to high myopia.
PURPOSE. To investigate the relationship between high myopia and single nucleotide polymorphisms (SNPs) in six proteoglycan genes: aggrecan (ACAN), fibromodulin (FMOD), decorin (DCN), lumican (LUM), keratocan (KERA), and epiphycan (EPYC). These genes were selected for study because they are involved in induced myopia in animals and/or are within the human MYP3 locus identified by linkage analys...
