Aparência de cápsula de disquete durante a facoemulsifica??o em manitol, olhos utilizados com glaucoma de fechamento angular

摘要

Phacoemulsification in short eyes can be challenging.Surgical manipulation in a shallow anterior chamberwith increased vitreous pressure tends to increase intraoperativecomplications. Intravenous mannitol isoften administered shortly before surgery to decreasevitreous pressure prophylactically. General anesthesiais preferred; if local anesthesia is chosen, peribulbar, orretrobulbar anesthesia should be avoided to prevent retrobulbarpressure. Topical anesthesia is preferable butgood eyelid akinesia is critical to prevent eyelid pressure.Regarding intraoperative precautions, surgery can beperformed under high infusion bottle height to deepenthe anterior chamber or the active fluidics systems canbe used. Limited pars plana vitrectomy is another precautionto increase anterior chamber depth (ACD)(1-3).
