[Irvine-Gass syndrome or cystoid macular edema due to aphakia].

Angiographically confirmed cystoid macula edema occurs in 8% of aphakic patients and 3% of these patients will suffer permanent reduction of visual acuity. This is apparently due to inflammatory reactions and to alterations of the vitreo-macular interface. Intracapsular cataract extraction has a higher incidence of angiographically confirmed CME clinical or persistent than extracapsular extraction. YAG-laser capsulotomy does not have any significant risk of CME. At present, there is no definitive clinically effective treatment.
