Aphakic cystoid macular edema. Longterm clinical observations. 1984

D M Taylor, and S W Sachs, and A L Stern

The incidence of clinically significant cystoid macular edema (CME) following cataract surgery has risen sharply with the widespread utilization of intraocular lenses. To evaluate the factors contributing to the incidence of CME, the senior author has divided 1808 of his own cataract cases into three groups according to procedures used: 1) intracapsular cataract extraction (ICCE) with no lens implantation; 2) ICCE with implantation of an iris-supported lens; and 3) extracapsular cataract extraction (ECCE) with implantation of a posterior chamber lens. The incidence of CME in these three groups was 2%, 9.9%, and 1.2%, respectively. Contributing factors and visual outcome in all three groups are reviewed. It is concluded that many of the problems associated with ICCE and iris-supported lens implantation seem to be eliminated with the ECCE-posterior chamber IOL procedure. However, it is emphasized that careful longterm follow-up is required to determine safety.

UI	MeSH Term	Description	Entries
D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.
D007910	Lenses, Intraocular	Artificial implanted lenses.	Implantable Contact Lens,Lens, Intraocular,Contact Lens, Implantable,Intraocular Lens,Intraocular Lenses,Lens, Implantable Contact
D008269	Macular Edema	Fluid accumulation in the outer layer of the MACULA LUTEA that results from intraocular or systemic insults. It may develop in a diffuse pattern where the macula appears thickened or it may acquire the characteristic petaloid appearance referred to as cystoid macular edema. Although macular edema may be associated with various underlying conditions, it is most commonly seen following intraocular surgery, venous occlusive disease, DIABETIC RETINOPATHY, and posterior segment inflammatory disease.
