Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain. Corneal thinning and ectasias combined with trivial trauma to the eye mostly by eye rubbing is considered as the underlying cause. With conservative approach self-resolution takes around 2 to 3 months. Surgical intervention is required in cases of non-resolution of corneal edema to avoid complications and for early visual rehabilitation. Intracameral injection of air or gas such as perflouropropane is the most common surgical procedure done. Recent investigative modality such as anterior segment optical coherence tomography is an extremely useful tool for diagnosis, surgical planning, and postoperative follow up. Resolution of hydrops may improve the contact lens tolerance and visual acuity but most cases require keratoplasty for visual rehabilitation.
急性角膜水肿是一种由于房水通过角膜后弹力层的撕裂而导致基质水肿的病症。患者表现为视力突然下降、畏光和疼痛。角膜变薄和扩张，加上轻微的眼外伤，主要是眼摩擦，被认为是潜在的原因。采用保守治疗，大约需要 2 到 3 个月自行缓解。如果角膜水肿不消退，需要手术干预以避免并发症并进行早期视力康复。最常见的手术方法是在眼内注射空气或氟丙烷等气体。最近的研究手段，如眼前节光学相干断层扫描，是一种非常有用的诊断、手术规划和术后随访工具。水肿的消退可以提高隐形眼镜的耐受性和视力，但大多数情况下需要进行角膜移植以恢复视力。
