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.
Generally, conjunctivitis does not affect the pupils. With acute angle-closure glaucoma , the pupil is generally fixed in mid-position, oval, and responds sluggishly to light, if at all. Shallow anterior chamber depth may indicate a predisposition to one form of glaucoma (narrow angle) but requires slit-lamp examination or other special ...
The new guidelines recommend monitoring intraocular pressure both pre- and post-injection. This recommendation stemmed from new evidence showing that routine intravitreal administration of anti-VEGF therapies may increase intraocular pressure for a sustained time period. [21] The 2014 guidelines addressed bilateral injections done in the same ...

An intracameral injection is usually of an antibiotic into the anterior chamber of the eyeball to prevent endophthalmitis caused by an infection of the eye that can occur after cataract surgery. The Food and Drug Administration (FDA) has not approved antibiotics for this use and it is considered 'off-label'.
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
Vaccination of dogs is the practice of animal vaccination applied to dogs. Programs in this field have contributed both to the health of dogs and to the public health . In countries where routine rabies vaccination of dogs is practiced, for example, rabies in humans is reduced to a very rare event.
Sub-Tenon injection is an ocular route of drug administration. It involves administration of a medication to the area between the sclera and the Tenon's capsule. [1] Posterior sub-Tenons steroid injections (PSTSI) is used in the treatment of posterior ocular inflammation, such as chronic uveitis. [2]
