Abstract Details


To evaluate efficacy of dexamethasone in eyes had Irvine Gass syndrome (IGS)


Retina Department of Ulucanlar Eye Research and Education Hospital


Eight patient had persistant macular edema (IGS) developed after phacoemulsification surgery and did not disappear more than 6 months postoperatively. Dexamethasone implant was performed for treatment of macular edema. Two patient had posterior capsule rupture during initial phacoemulsification, one of which had history of pars plana vitrectomy for IOL extraction which drop one week after cataract surgery. Two subject had diabetes Mellitus without retinopathy, one subject had Chronic Obstructive Pulmonary Disease due to heavy smoking. Each patient underwent OCT and FFA evaluation in addition to clinical fundoscopic observation.


The mean dexamethasone implant time was 11 months (range of 6 months to 26 months) postoperatively. The mean level of macular edema was 530µ ( 396-840µ) in pretreatment period which decreased in 270 µ (246-380 µ) after implantation. Recurrence of edema was observed in 2 subject 4 months after the first injection the who had complicated cataract surgery and received second implantation. The rest of them successfully treated with only one injection. No one had any complication such as elevation of IOP, ocular inflammation and implant migration into the anterior chamber in either eye.


Dexametasone implantation is safe and effective treatment chose for Irvine Gass syndrome
