The purpose of this study project is to investigate the genes and their sequence alterations that are associated with high myopia.
2 years including pateints follow-up, laboratory analysis, statistical analysis, data interpretation
Control subjects with normal visual acuity, no ocular disorders, IOP velow 22 mm Hg and no family or personal history of high myopia.
Inclusion criteria: Plan to carry out whole genome scan and linkage studies of 30 independent pedigrees of at least 3 generations, each with more than 10 members and 3 high myopia that we have recruited. None of these families have myopia associated disease such as Stickler's syndrome, Marfan syndrome and juvenile glaucoma.

Advancing knowledge in basic molecular genetics.
1. Affirm chromosomal loci linked to myopia. 2. Identify new myopia genes. 3. Reveal the frequencies of specific sequence alterations in the new putative myopia gene(s) in the local Chinese population. 4. Establish a basis to study interactive effects between environmental and genetic factors that contribute to myopia.
