Abstract

Intravitreal injection of triamcinolone, Anti VEGF & antibiotics are given in various retinal conditions. It was found that during injection increased IOP may lead to compromised optic disc perfusion & vitreous incarceration in needle track after its removal & subconjunctival vitreous.To have a safe intravitreal injection we have devised a simple but very helpful technique to lessen the IOP. A 26 or 30 G needle hub is mounted on sterile ear bud to obstruct its inner hole, then it is pierced tangentially into the anterior chamber till its bevel is half in AC & not surpassing pupil border so that lens touch is avoided. As soon as the medicine is injected,the extrafluid (aqueous) comes out through needle & soaked in the sterile ear bud. After removal of intravitreal needle no vit incarceration or subconjunctival vitreous were noted, IOP remains stable. Dramatically less pain was noted. At the end you find stable AC & IOP without any complications.
