Abstract：
Background: To evaluate changes in the visual field (VF) after Descemet stripping automated endothelial keratoplasty (DSAEK) in eyes with advanced glaucoma and previous trabeculectomy. Methods: Changes in VF, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and number of glaucoma medications were analyzed before and after DSAEK in 19 eyes. The VFs were evaluated using the 10-2 program of the Humphrey Field Analyzer (HFA) and/or Goldmann perimetry (GP). Results: In nine eyes, the MD improved from -22.24 ± 6.5 dB to -18.36 ± 5.1 dB in HFA. In five out of nine eyes, postoperative MD improved >1 dB compared to preoperative MD. In GP testing, 10 out of 15 eyes showed an improvement, that is, greater than 20° in VF enlargement by the isopter of I-4e and/or new detection of a smaller or darker isopter. Overall, improvement in VF with the HFA and/or GP test was observed in 12/19 (63.2%) eyes after DSAEK. Postoperative BCVA improved by more than two lines in logMAR VA in 18 of 19 (94.7%) eyes. There were no significant differences between the preoperative and postoperative IOP and the number of glaucoma medications. Conclusions: DSAEK may produce subjective improvement in the visual field as well as improved visual acuity, even in advanced glaucomatous eyes.
摘要：
背景：评估患有晚期青光眼和先前小梁切除术的眼睛的Descemet剥离自动内皮角膜移植术（DSAEK）后视野（VF）的变化。方法：VF的变化，最佳矫正视力（BCVA），眼内压（IOP），分析了19只眼DSAEK前后的青光眼药物数量。使用Humphrey场分析仪(HFA)和/或Goldmann视野计(GP)的10-2程序评估VF。结果：在九只眼睛中，HFA的MD从-22.24±6.5dB提高到-18.36±5.1dB。九只眼睛中有五只，与术前MD相比，术后MD改善>1dB。在GP测试中，15只眼睛中有10只表现出改善，也就是说,通过I-4e的等压纸器和/或新检测到较小或较暗的等压纸器在VF扩大中大于20°。总的来说,在12/19(63.2%)眼DSAEK后,用HFA和/或GP试验观察到VF改善.在19只眼中的18只（94.7％）眼的logMARVA中，术后BCVA改善了两行以上。术前和术后眼压和青光眼药物的数量之间没有显着差异。结论：DSAEK可以在视野中产生主观改善以及改善视力，即使是晚期青光眼的眼睛。
