The combination of intravitreal triamcinolone injection and cataract surgery in patients with diabetic retinopathy

Abstract

Diabetic retinopathy (DR) is the most common blinding ocular complication of DM. Diabetic retinopathy is amicroangopathy that exhibits both features of microvacular occlusion and leakage. The exact mechanism for diabetic microangiopathy remains unclear. It has been postulated that hyperglycemia initiates cascade of downstream vascular events through variety of mechanisms. Combining cataract surgery with triamcinolone rather than giving triamcinolone before surgery as a separate procedure avoided the potential for progression of lens opacities associated with intraocular steroids, which could have further interfered with retinopathy assessment Key words : Diabetic retinopathy – triamcinolone - Cataract surgery
