Irvine Gass syndrome

Irvine-Gass syndrome, pseudophakic cystoid macular edema or postcataract CME is one of the most common causes of visual loss after cataract surgery. The syndrome is named in honor of S. Rodman Irvine and J. Donald M. Gass.

The incidence is more common in older types of cataract surgery, where postcataract CME could occur in 20-60% of patients, but with modern cataract surgery, incidence of Irvine-Gass syndrome have reduced significantly.
