Repair of Near Total Descemet's Membrane Detachment with Intracameral Injection of 20% Sulfur Hexafluoride Gas
並列摘要
To report a case of reattachment of detached Descemet's membrane after intracameral injection of sulfur hexafluoride gas. An 84-year-old man underwent phacoemulsification of the right eye on December 10^(th), 2001. During operation an undulating Descemet's detachment involving the central cornea was observed and manipulation with viscoelastic substance and gas tamponade was performed at the end of surgery. However a nonplanar Descemet's detachment involving the central 2/3 of the cornea with moderate overlying corneal edema was found one day postoperatively. Medical treatment was prescribed for his right eye initially. Two weeks later the Descemet's detachment had progressed more diffusely and the vision had decreased to counting finger. An intracameral injection of sulfur hexafluoride (SF6) was performed on December 27^(th), 2001 because of no improvement of right eye. The complete reattachment of Descemet's membrane of right eye with clear cornea occurred one week after the SF6 injection. The vision had improved to 20/40. Descemetopexy with 20% SF6 can successfully repair near total detachment of Descemet's membrane with complete resolution of corneal edema, thereby obviating the need for penetrating keratoplasty. Although reattachment may take a period of time, the detached endothelium/Descemet's membrane complex remains relatively healthy in the anterior chamber with the eventual return of corneal clarity when reattachment occurs.
