正常眼，弱視既往眼，弱視眼の黄斑部網膜厚

Retinal thickness in the macular area in normal eyes and in eyes with current or past amblyopia

要約　目的：正常眼，弱視既往眼，弱視眼での黄斑部網膜厚の報告。対象と方法：3～13歳（平均5.6歳）の幼小児67眼を対象とした。正常眼22眼，弱視既往眼25眼，弱視眼20眼で，屈折は＋2～＋5Dの範囲にあった。黄斑部網膜厚は光干渉断層計（OCT）で測定した。結果：3群間の屈折には有意差がなかった。Foveal minimum，fovea，inner retinaの網膜厚は3群間に有意差がなかった。結論：幼小児の黄斑部網膜厚には，屈折の影響があるouter retina領域を除き，正常眼，弱視既往眼，弱視眼で差がない。

Abstract.　Purpose：To report the retinal thickness in the macular area in normal eyes and in eyes with current or past amblyopia. Cases and Method：This study was made on 67 eyes in infants and children aged between 3 and 13 years,average 5.6 years. The series comprised 22 normal eyes,25 eyes with history of amblyopia,and 20 eyes with amblyopia. The refraction ranged from ＋2 to ＋5 diopters. Thickness of the fovea and surrounding area was measured using an optical coherence tomography（OCT）. Results：There was no difference in refraction among the 3 groups. Thickness of the foveal minimum,fovea and inner retina area was statistically the same among the 3 groups. Conclusion：There is no difference in retinal thickness in the macular area among normal eyes,eyes with history of amblyopia,and eyes with amblyopia except the outer retina area.
