OBJECTIVE
To describe a patient who developed a Descemet membrane detachment after hydrogen peroxide injury with successful reattachment by intracameral injection of sulfur hexafluoride gas.
METHODS
Case report.
RESULTS
The right eye of a 40-year-old man was exposed to 35% hydrogen peroxide. This resulted in a central corneal epithelial defect, corneal edema, a localized detachment of Descemet membrane, and a gas bubble between the posterior corneal stroma and Descemet membrane. The Descemet membrane detachment persisted after reabsorption of the gas bubble. Successful reattachment of Descemet membrane was achieved with injection of 0.15 mL of 20% sulfur hexafluoride gas into the anterior chamber.
CONCLUSION
Hydrogen peroxide ocular injury may cause Descemet membrane detachment, and successful reattachment may be achieved with intracameral injection of 20% sulfur hexafluoride gas.
目的
描述一名过氧化氢损伤后发生后弹力层脱离的患者，通过前房内注射六氟化硫气体成功实现后弹力层复位。
方法
病例报告。
结果
一名40岁男性右眼暴露于35%的过氧化氢中。这导致中央角膜上皮缺损、角膜水肿、后弹力层局限性脱离，以及角膜后基质层与后弹力层之间出现气泡。气泡吸收后，后弹力层脱离仍持续存在。向前房内注射0.15 mL 20%的六氟化硫气体后，后弹力层成功复位。
结论
过氧化氢眼部损伤可能导致后弹力层脱离，前房内注射20%的六氟化硫气体可成功实现后弹力层复位。
