What does conjunctival injection indicate?
Conjunctival injection or hyperemia is a nonspecific response with enlargement of conjunctival vessels induced by various diseases. Conjunctival injection is an important diagnostic clue for infection or inflammation and can be utilized for the monitoring of the disease progression and response to treatment.
What is Circumcorneal congestion?
Circumcorneal congestion may be seen due to enlargement of the episcleral vessels in the region of the ciliary body. Keratic precipitates (KPs) are cellular deposits on the corneal endothelium.
What is episcleral injection?
Episcleral injection is an external sign of intraocular disease, such as anterior uveitis and glaucoma (Figures 3 and 4). Occasionally, episcleral injection may occur in diseases of the sclera, such as episcleritis or scleritis.

The sclera is a tough, opaque, fibrous tissue. This connective tissue helps to maintain the shape of your eyeball, while the conjunctiva is a mucous membrane covering the outer part of your sclera.
What does ciliary injection mean?
Ciliary injection involves branches of the anterior ciliary arteries and indicates inflammation of the cornea, iris, or ciliary body. Conjunctival injection mainly affects the posterior conjunctival blood vessels.
What is ocular congestion?
The symptoms of viral conjunctivitis are variable but usually feature an intensely red eye and excessive watery discharge that is not green or yellow. Viral cold-like symptoms, such as nasal congestion and runny nose, may also be present. The eyelids may be swollen and the eyes sensitive to bright light.
How do conjunctival and ciliary congestion differ?
The key is recognizing cases requiring ophthalmological consultation by differentiating between ciliary and conjunctival injection. Ciliary injection indicates inflammation of the cornea, iris, or ciliary body, whereas conjunctival injection mainly affects the posterior conjunctival blood vessels.
What does injection mean for eye?
More specifically, ophthalmologists inject medication directly into your eyeball to treat certain conditions. Ophthalmologists call these shots intravitreal injections, and they can save your sight. Diabetic eye disease, AMD and retinal vein occlusion respond well to medication injections.
What causes redeye?
Red eyes usually are caused by allergy, eye fatigue, over-wearing contact lenses or common eye infections such as pink eye (conjunctivitis). However, redness of the eye sometimes can signal a more serious eye condition or disease, such as uveitis or glaucoma.
What does conjunctival mean?
Conjunctival: Pertaining to the conjunctiva, the clear moist membrane that covers the inner surfaces of the eyelids and the front of eyeball.
What is Circumcorneal zone of conjunctiva?
Medical Definition of circumcorneal injection
: enlargement of the ciliary and conjunctival blood vessels near the margin of the cornea with reduction in size peripherally.
What is the cornea part of?
The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye).
What is Hypopyon corneal ulcer?
Hypopyon is a medical condition involving inflammatory cells in the anterior chamber of the eye. It is an exudate rich in white blood cells, seen in the anterior chamber, usually accompanied by redness of the conjunctiva and the underlying episclera.
How do adults get conjunctivitis?
Viral conjunctivitis is highly contagious. Most viruses that cause conjunctivitis spread through hand-to-eye contact by hands or objects that are contaminated with the infectious virus. Having contact with infectious tears, eye discharge, fecal matter, or respiratory discharges can contaminate hands.

How is Proptosis diagnosed?
Tests and Diagnosis of Proptosis (Bulging Eye)- A blood test to make sure the thyroid gland is functioning properly.
- Examination with an exophthalmometer, to measure the degree of protrusion.
- Imaging scans to examine the eye socket and orbit.
- An MRI or CT scan of the brain to assess its structure.
What is ciliary epithelium?
The ciliary epithelium of the ciliary processes produces aqueous humor, which is responsible for providing oxygen, nutrients, and metabolic waste removal to the lens and the cornea, which do not have their own blood supply.
What is the difference between scleritis and Episcleritis?
Episcleritis is inflammation of the superficial, episcleral layer of the eye. It is relatively common, benign and self-limiting. Scleritis is inflammation involving the sclera. It is a severe ocular inflammation, often with ocular complications, which nearly always requires systemic treatment [1,2].
Does Conjunctivochalasis go away?

Does sclera cover cornea?
The sclera is the white part of the eye that surrounds the cornea. In fact, the sclera forms more than 80 percent of the surface area of the eyeball, extending from the cornea all the way to the optic nerve, which exits the back of the eye. Only a small portion of the anterior sclera is visible.
Does conjunctiva cover the cornea?
The conjunctiva is the membrane that lines the eyelid and loops back to cover the sclera (the tough white fiber layer covering the eye), right up to the edge of the cornea (the clear layer in front of the iris and pupil—see Structure and Function of the Eyes.
