 Retinal Venous Occlusive disease is the second only to diabetic retinopathy as a major cause of blindness associated with retinal vascular disease. Macular edema is a major cause of vision loss in patients presenting with central abd hemi vein occlusions. Currently, there is no proven treatment to address macular edema in these patients. In the past laser photocoagulation has been used, but was found to offer no visual benefits over the natural history in the treatment of macular edema associated with CRVO. Investigators have demonstrated in case reports that intravitreal triamcinolone Kenalog may result in the reduction in macular edema, leading to visual improvement in some patients with CRVO. Triamcinolone is relatively well tolerated in many patients, but its use is associated with significant risk of elevated intraocular pressure, cataract, and intraocular infection.
