Iris and macular angiography in intraocular implants

We performed an angiographic study of the iris and retina of 121 implanted eyes and 94 aphakic eyes 15 days, three months, six months, and 12 months postoperatively to determine the incidence of cystoid macular edema (CME) and iris leakage and the relationship between them. The angiographic study shows that iris leakage is a common feature of cataract surgery in the immediate postoperative period. Apparently the type of extraction (extracapsular or intracapsular) does not influence the appearance of these iris angiographic findings. However, the percentage of observed CME after three months is less (P less than 0.05) in patients with an intraocular lens (IOL) who have had extracapsular cataract extraction (ECCE) than in patients who have had intracapsular cataract extraction (ICCE) and the presence of CME is closely related to the angiographically observed iris leakage.
