Little doubt the process of intravitreal injections has anchored itself as one of the crucial generally used practices in outpatient clinics of ophthalmology due to its easiness, excessive safety and superior outcomes over different methods as laser photocoagulation.
However since there’s nothing devoid of flaws, we are going to spotlight the most typical problems after intravitreal procedures and the best way to reduce their incidence.
Problems of intravitreal injections might be categorized it to three classes:
A. Problems associated to the approach used for making ready sufferers earlier than present process intravitreal injection:
1. The usage of lidocaine jelly as a topical anesthetic might act as bodily barrier to the motion of topical antimicrobial medicine, so the topical antimicrobial drug ought to be instilled within the eye and allowed to behave for at the very least 30 seconds earlier than utilizing the lidocaine jelly.
