要約　目的：黄斑部の網膜神経節細胞層複合体厚（GCC）の光干渉断層計（OCT）による測定値の，水晶体の有無による違いの報告。対象と方法：スペクトラルドメインOCTで，白内障手術前後でのシグナル強度（SSI）とGCC厚を22眼で測定した。平均年齢は75.2歳，術前の平均視力は0.5±0.2であった。結果：GCCの平均厚は術前82.1μm，術後98.0μmで，有意差があった（p＜0.0001）。術前後のSSIの差と水晶体混濁指数との間には有意差があった（r＝0.47，p＜0.02）。SSIとGCCそれぞれの術前後の差には有意な相関があった（r＝0.70，p＜0.0001）。結論：スペクトラルドメインOCTで測定したGCC厚とSSIは，白内障眼では小さい値が得られる。
