Schematic diagram of the human eye showing. Subconjunctival injection is a type of periocular route of injection for ocular drug administration by administration of a medication either under the conjunctiva or underneath the conjunctiva lining the eyelid.. Using the subconjunctival injection bypasses the fatty layers of the bulbous conjunctiva and putting medications adjacent to sclera …

Choose the site for the injection in the lower or upper fornix and, as appropriate, raise or lower the eyelid. Ask the patient to look in the opposite direction and fix his/her gaze. Tell the patient to expect a slight pressure sensation and keep reassuring him/her.

Subconjunctival injections. Injections may be administered under the conjunctiva. The subconjunctival medication gains access to the eye by absorption into the bloodstream by the episcleral and conjunctival vessels. Subconjunctival injections are used primarily in the treatment of intraocular infection. Continuous-release delivery

2022年8月26日 · For a few hours, you may have some eye irritation. You could also have a spot of blood on the eye (called a subconjunctival hemorrhage) at the injection site. This happens rarely and usually clears up within a week. Fortunately, complications after eye injections are rare.

2012年1月15日 · The types of injections used for conditions of the eye and adnexa include intramuscular, intradermal, subcutaneous, subconjunctival and sub-Tenon’s, intravitreal, intravenous and intracameral injections. Let’s look at each in turn.

Subconjunctival injections can be given either under the eyeball conjunctiva (epibulbar) or underneath the conjunctiva lining the eyelid (subpalpebral). Subconjunctival injections are indicated for treatment of lesions in the cornea, sclera, anterior uvea and vitreous.

2023年5月7日 · Subconjunctival injection of local anesthesia involves direct infiltration of anesthetic under the conjunctiva. This local infiltration technique may be used in a variety of procedures, including intravitreal injections, cataracts, glaucoma, and pterygium surgery.

Alternatively, subconjunctival injection is a minimally invasive and straightforward technique frequently used in ophthalmology. It enables performance of local treatments using high cell doses.

2001年10月12日 · Subconjunctival injections are easier and generally safer to perform than sub-Tenon’s. In the former, you create a “tent” with toothed forceps at the superior or inferior temporal conjunctiva, and administer the injection beneath the conjunctiva.

2021年1月13日 · Subconjunctival injection, the focus of the present review, is a straightforward technique that is frequently used in the daily ophthalmologic practice to administer different drugs. This approach employs a simple, safe, and minimally invasive technique to deliver locally high cell doses in a low volume [13].
