Normally, the elevation of optic disk swelling is measured by ophthalmoscopy. Laser scanning tomography (LST) permits three-dimensional analysis of distinct intraocular structures under in vivo conditions with high accuracy. We present a case of papillitis, in which the elevation could be determined as 550 microns, leading to a volume of 1.48 mm3, increasing to an elevation of 870 microns and a volume of 1.72 mm3 11 days later. Clinically, we found a swelling of about 1 D in the first examination, increasing to 2 D at the maximum. Six weeks later there was only a distinct temporal pallor to be seen, while the LST showed us an elevation of 190 microns (volume 0.22 mm3).
通常,视盘水肿的高度通过检眼镜检查来测量。激光扫描断层扫描(LST)能够在活体条件下对不同的眼内结构进行高精度的三维分析。我们报告一例视乳头炎病例,其中视盘水肿高度最初测定为550微米,体积为1.48立方毫米,11天后水肿高度增加到870微米,体积为1.72立方毫米。临床上,我们在首次检查时发现约1屈光度的肿胀,最大时增加到2屈光度。六周后,仅可见明显的颞侧苍白,而LST显示水肿高度为190微米(体积0.22立方毫米)。
