Intravitreal injection of triamcinolone,Anti VEGF & antibiotics are given in various retinal conditions.It may be a single or multiple injections at one time depending on the retinal condition.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.One or many intravitreal medicines can be injected without any rise in IOP or vitreous incarceration or any subconjunctival vitreous.A 26 or 30 G needle hub is penetrated with sterile ear bud to obstruct its inner hole,then it is penetrated horizontally into the anterior chamber till its bevel is in AC & not surpassing pupil border so that lens touch is avoided.Now intravitreal injection one or many are given without any fear of rise in IOP.As soon as the medicine is injected,the extrafluid (aqueous) comes out through needle & soaked in the sterile ear bud.After
