Cystoid Macular Edema after Complicated Cataract Surgery Resolved by an Intravitreal Dexamethasone 0.7-mg Implant.Case Rep Ophthalmol. 2011 Sep; 2(3):319-22.CR
To report the effective treatment of cystoid macular edema (CME) following complicated cataract surgery (resulting in Irvine-Gass syndrome) with a dexamethasone 0.7-mg (Ozurdex(®)) intravitreal implant.
An interventional case report with optical coherence tomography (OCT) scans.
An 83-year-old Caucasian woman was suffering from CME following complicated cataract surgery on her left eye. She had undergone 3 intravitreal injections of dexamethasone 0.4 mg in the 3 months following the surgery without any improvement of visual function. Seven months after the cataract surgery, she received a single intravitreal injection of dexamethasone 0.7 mg (Ozurdex). Four weeks following the injection, her best-corrected visual acuity improved from 0.3 to 0.8. CME resolved with a reduction of central retinal thickness from 393 μm pre-Ozurdex injection to 212 μm post-Ozurdex injection, as measured by OCT scan.
Dexamethasone 0.7 mg (Ozurdex) has proven to be an effective treatment option in retinal vein occlusion and non-infectious uveitis. It can also be considered as off-label treatment in Irvine-Gass syndrome.
