Retrobulbar/subconjunctival injections



Injections in in ophthalmology are used to deliver as much of the drug as possible as close to the affected tissue as possible.

In ophthalmology, we mainly use steroid, antibiotic and anti-VEGF injections.

  • Steroid injections are sub-tenon injections of a pharmaceutical suspension, which is slowly released over 2 to 3 weeks. The most common indications are uveitis, inflammation around the optic nerve and swelling of the cornea.
  • Antibiotic injections are administered under the conjunctiva or inside the eye. They are used to treat infections of the eyeball.
  • Anti-VEGF preparations are used to treat exudative AMD, and are discussed here: Services / Ophthalmological procedures / Intravitreal injections


  • The procedure is almost painless, as a local anesthesia is performed beforehand.
  • During the procedure, the patient may be in a standing or lying position.
  • After disinfecting the skin of the lower eyelid, the patient is instructed to look upward. The doctor then inserts a needle into the area of the inferior-lateral orbital angle and directs it toward the top of the orbit. The drug is injected after aspiration (to ensure the medication is not inadvertently delivered into a blood vessel).
