The topography of corneas after penetrating keratoplasty is highly variable. We classify the topography into five groups.
We performed videokeratography on 45 clear compact penetrating keratoplasties, with all sutures removed. Three ophthalmologists classified the keratographs independently into five previously defined topographic groups, based on the pattern of the normalized color-coded videokeratograph.
The five topographic patterns included: prolate bow tie, 14 (30%); oblate bow tie, 14 (30%); mixed prolate and oblate bow tie, 8 (17%); asymmetric, 3 (9%); and steep/flat, 6 (14%). The three ophthalmologists agreed in their initial classification in 87% of the cases and after discussion, in 96%.
The topography of the cornea after penetrating keratoplasty can be classified into five qualitative groups by trained observers, with good clinical reliability.
穿透性角膜移植术后角膜地形图变化很大。我们将其分为五组。
我们对45例已拆除所有缝线的透明致密穿透性角膜移植术进行了角膜地形图检查。三位眼科医生根据标准化彩色编码角膜地形图的模式,将角膜地形图独立分为五个预先定义的地形学组。
五种地形学模式包括:长轴领结形,14例(30%);短轴领结形,14例(30%);长轴和短轴混合领结形,8例(17%);不对称形,3例(9%);陡峭/扁平形,6例(14%)。三位眼科医生在初始分类中的一致率为87%,经过讨论后,一致率为96%。
经过培训的观察者可将穿透性角膜移植术后的角膜地形图分为五个定性组,具有良好的临床可靠性。
