  • Publication number: 20030060763
    Abstract: This invention relates to the art of intraocular injection as a means of treating various conditions of the eye. In particular it relates to a plaque containing guide means for location of a needle entry point into the eye which thereby facilitates such injection. The invention also relates to a kit which includes (1) an intraocular composition containing an active compound able to treat the particular condition; (2) a syringe for dispensing the composition through a needle coupled to the syringe, the syringe having dimensions such that blockage of the needle is minimised; and (3) a plaque containing guide means for location of the needle entry points into the eye. In one form, it provides for a kit which includes (i) an anti-inflammatory steroid which is the active agent in treating the macular degeneration; (ii) a syringe need for the delivery of that steroid through a needle coupled to the syringe, and (iii) a plaque which facilitates correct positioning of the needle.
