To report the occurrence of acute hydrops 52 months after successful deep anterior lamellar keratoplasty (DALK) using the Anwar big-bubble technique in a keratoconic eye.
A 20-year-old man with a history of bilateral keratoconus who had undergone DALK in his right eye, presented with complaints of sudden visual reduction, photophobia, redness, and pain in the same eye.
Review of his clinical course, slit-lamp biomicroscopy, and laboratory evaluation, including ultrasound biomicroscopy, revealed acute hydrops in the graft. He was medicated with hypertonic solutions but because of persistent graft edema and nonattached Descemet membrane, penetrating keratoplasty was performed. Histopathologic examination confirmed the diagnosis.
Similar to penetrating keratoplasty, acute hydrops can occur after DALK using the big-bubble technique in patients with keratoconus.
报告一例圆锥角膜患者行 Anwar 大泡技术深板层角膜移植术后 52 个月发生急性角膜水肿。
一名 20 岁男性，双眼均患有圆锥角膜，曾于右眼行深板层角膜移植术（DALK），现出现右眼突发视力下降、畏光、眼红和疼痛等症状。
回顾其临床过程、裂隙灯生物显微镜检查和实验室评估，包括超声生物显微镜检查，显示移植物中发生急性角膜水肿。他接受了高渗溶液治疗，但由于持续的移植水肿和未附着的后弹力膜，行穿透性角膜移植术。组织病理学检查证实了诊断。
与穿透性角膜移植术类似，大泡技术 DALK 后也可发生急性角膜水肿，尤其是在圆锥角膜患者中。
