  1. Macular edema

    Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye and causes it to thicken and swell. The swelling may distort a person's central vision, as the macula is near the center of the retina at the back of the eyeball. This area holds tightly packed cones that provide sharp, clear central vision to enable a person to see detail, form, and color that is directly in the direction of gaze. Macular edema sometimes appear for a few days or weeks after cataract surgery, but most such cases can be successfully treated with NSAID or cortisone eye drops. Until recently there were no good treatments for macular edema caused by central retinal vein occlusion. Laser photocoagulation has been used for macular edema caused by branch retinal vein occlusion.

  1. 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.
