Outline of Final Research Achievements

We divided the visual field (VF) pattern (i.e., superior, inferior, and central) of 1,100 primary open-angle glaucoma (POAG) subjects, including normal-tension glaucoma (NTG) subjects, in which we had 1000K gene chip variant data. We performed a genome-wide association study (GWAS) of the VF pattern of 635 subjects (331 superior and 304 inferior cases), excluding subjects with an undetectable and central pattern as follows: 1) if the subject had a different VF in both eyes, it was analyzed as inferior (n=635), and 2) if the VF pattern was the same in both eyes (n=515). We could not detect a significant variant associated with VF pattern. In order to detect the correct variants that are associated with the VF pattern, we must collect subjects prospectively with their VF at the early stage, and keep the collect DNA from more than 1000 POAG patients.
