Objective: To investigate the association of endothelial nitric oxide synthase (NOS), inducible NOS, manganese superoxide dismutase (SOD), and extracellular SOD gene polymorphisms with susceptibility to Behçet disease (BD) in Japan. Methods: Seventy-eight consecutive Japanese patients with BD and 107 healthy control subjects were genotyped by polymerase chain reaction or polymerase chain reaction-restriction fragment length polymorphism methods for endothelial NOS polymorphisms in intron 4, exon 7, and promoter region; inducible NOS polymorphisms in exon 16 and promoter region; manganese SOD Ala16Val polymorphism; and extracellular SOD Arg213Gly polymorphism. HLA-B*51 alleles, which have been found to be associated with BD, were also determined. Results: The frequencies of manganese SOD Val16 increased significantly in patients with BD. The manganese SOD-Val/Val genotype and HLA-B*5101 had a synergistic role in controlling susceptibility to BD. There was no significant difference in the frequencies of endothelial NOS, inducible NOS, and extracellular SOD gene polymorphisms between patients with BD and control subjects. Conclusion: The manganese SOD Val16 allele is associ-atedwiththedevelopmentofBDinJapan.ExtracellularSOD, endothelial NOS, and inducible NOS gene polymorphisms do not constitute a risk factor for developing BD in Japan. Clinical Relevance: The manganese SOD gene polymorphism seems to contribute to BD.

PPV for DME effectively improved VA and reduced foveal thickness for a longer postoperative period. Better preoperative VA was associated with better final postoperative VA. The eyes without CME tended to have better final postoperative VA.

Although adjunctive use of TA after PPV for DME improved VA and foveal thickness, the effect was transient and foveal thickness increased significantly compared with the PPV alone group at 12 months postoperatively.
