However since there’s nothing devoid of flaws, we’ll spotlight the commonest issues after intravitreal procedures and how one can reduce their incidence.
Issues of intravitreal injections could be categorized it to three classes:
A. Issues associated to the approach used for making ready sufferers earlier than present process intravitreal injection:
