High myopia (pathological myopia) is caused by excessive axial elongation that primarily involves the ora-equatorial area and the posterior pole. Pathological myopia often accompanied by glaucoma, cataracts, macular degeneration, and retinal detachment, leading to blindness when the damage to the retina is extremely severe. Population and family studies in Chinese have provided evidence for a geneticcomponent to pathologic myopia. Children of myopic parents are more likely to have myopia than are children of nonmyopic parents. Therefore, it is possible to search a potential candidate gene for myopia through the genomic study of pathological myopia. The retina receives the signal from the retina-RPE complexes and affects the growth of scleral coats. The changes of scleral components, collagen fibrils and proteoglycans, are noted in experimental and human myopia and induce the pathology of high myopia. It is interesting to know that individual difference of SNP in the components of scleral coat affects the response to the signal from retina-RPE complexes. The most important effectors in scleral coats are collagens, proteoglycans, MMPs and TIMPs. Therefore, the difference of SNPs in different genes might contribute the formation of scleral thinning during myopia development. In this project, we will focus on this subject by using GenomeLab SNPstream Genotyping System which is powerful and helpful for identify some specific SNPs in the regard.
