Subconjunctival Injection
About the procedure
A subconjunctival injection involves administering medication, such as antibiotics or steroids, directly beneath the conjunctiva. This method delivers high local concentrations of drugs to treat severe ocular infections, inflammation, or as adjunctive therapy. The procedure is performed under sterile conditions after topical anaesthesia, with a small volume injected into the subconjunctival space. Clinical examination determines the indication, and cultures may be obtained if infection is suspected. Post-procedure care focuses on monitoring for discomfort or local reactions while continuing systemic or topical therapy as prescribed.
Care before the procedure
- Avoid rubbing eyes prior to the injection procedure.
- Inform the doctor about allergies and current medications.
- Remove contact lenses before the procedure if worn.
- Ensure no active eye infection is present unless being treated.
Care during the procedure
- Sit still while topical anaesthetic is applied to the eye.
- Keep eyes open or as instructed during the injection.
- Avoid sudden movements to prevent injury during needle placement.
- Notify the clinician immediately if experiencing sharp pain.
Care after the procedure
- Mild discomfort or redness may occur at the injection site.
- Avoid rubbing or pressing the injected eye.
- Continue prescribed systemic or topical medications as directed.
- Monitor for increased pain, swelling, or vision changes and report promptly.
Eligibility
- Patients with severe ocular infections requiring a high local antibiotic concentration.
- Individuals with intraocular or periocular inflammation needing steroid delivery.
- Patients requiring adjunctive therapy for conditions not responsive to topical drops alone.
- People with targeted ocular conditions where systemic therapy may be insufficient or slow-acting.
