A 65-year-old male was planned for Deep anterior lamellar keratoplasty (DALK) to improve his visual quality from the underlying spheroidal degeneration along the visual axis. An attempt for a big bubble was futile, hence converted to a manual DALK. On postoperative day 1, he developed secondary angle closure glaucoma due to reverse pupillary block by the host DM. Decompression of the big bubble was done and angle closure was resolved with a good visual outcome at 1-month post-op. We present the first case of secondary angle closure glaucoma due to reverse pupillary block by a big bubble in a rigid cornea. DALK = Deep anterior lamellar keratoplasty, OD = oculus dexter, OS = oculus sinister, DS = Diopters Sphere, DC = Diopters cylinder, AS-OCT = anterior segment optical coherence tomography, DM = Descemet's membrane, IOP - Intraocular pressure, GHJ = Graft-host junction, BSS = Balanced salt solution.
一位 65 岁男性计划接受深层前板层角膜移植术（DALK），以改善沿视轴存在的球形变性引起的视觉质量。试图制造一个大的气泡，但没有成功，因此改为手动 DALK。术后第 1 天，由于宿主 DM 的瞳孔后阻滞，他发生了继发性闭角型青光眼。大的气泡减压后，通过角关闭解决，术后 1 个月视力恢复良好。我们报告了首例由于刚性角膜中大气泡的瞳孔后阻滞引起的继发性闭角型青光眼。DALK =深层前板层角膜移植术，OD =右眼，OS =左眼，DS =球镜度数，DC =柱镜度数，AS-OCT =前节光学相干断层扫描，DM =Descemet 膜，IOP =眼内压，GHJ =移植物-宿主交界处，BSS =平衡盐溶液。
