Posterior subtenon steroid injection

Smith and Nozik technique  Conjunctiva is anesthetized with proparacaine drops or better local anesthesia is given and a wire speculum is placed.  Patient is asked to look inferonasally  Conjunctiva is lifted with help of blunt serrated forceps  Syringe filled with 0.5-1mL(20-40 mg) of triamcinolone and fitted with 25/26/27 gauge needle is advanced with bevel facing toward the globe, supero/temporally along the curve of the globe. Intermittent sidewise sweeping movement is done to confirm the separation of needle from sclera.  The needle is advanced till the hub touches the conjunctiva.  Plunger is slightly withdrawn to rule out injecting steroids within a vessel, triamcinolone is injected and needle is withdrawn.  Antibiotic drops are then instilled into the eye.
