Difference Between Injected Conjunctiva and Sclera
Here is a detailed overview of the differences between injected conjunctiva and sclera in table format.
|
Feature |
Injected Conjunctiva |
Injected Sclera |
|
Definition |
Injected conjunctiva refers to redness and inflammation of the bulbar conjunctiva, often caused by increased blood flow to the area. |
Injected sclera refers to redness and inflammation of the sclera, usually due to underlying conditions affecting the deeper layers of the eye. |
|
Location |
The redness affects the thin, transparent membrane covering the white part of the eye and lining the eyelids. |
The redness is localized to the white part of the eye, specifically the fibrous outer layer beneath the conjunctiva. |
|
Appearance |
Appears as diffuse redness or pinkness of the conjunctiva, sometimes with visible blood vessels. |
Appears as deeper, more pronounced redness of the sclera, often with a more intense color change compared to conjunctival injection. |
|
Causes |
Can be caused by conjunctivitis (viral, bacterial, or allergic), exposure to irritants, dryness, or foreign bodies. |
Can be caused by scleritis (inflammation of the sclera), episcleritis, trauma, or severe systemic conditions. |
|
Symptoms |
Symptoms may include redness, irritation, itching, and discharge. There may be discomfort but not necessarily pain. |
Symptoms may include pronounced redness, pain or tenderness, light sensitivity, and sometimes blurred vision. |
|
Diagnosis |
Diagnosed through a visual examination of the conjunctiva and sometimes a slit-lamp exam to check for signs of infection or inflammation. |
Diagnosed through a thorough eye examination, including a visual and slit-lamp assessment to differentiate from conjunctival injection and identify underlying conditions. |
|
Treatment |
Treatment may involve topical antibiotics or antihistamines, lubricating eye drops, and avoiding irritants. |
Treatment varies based on the underlying condition and may include anti-inflammatory medications, immunosuppressants, or specific therapies for associated systemic diseases. |
|
Prognosis |
The prognosis is generally good with appropriate treatment, often resolving with minimal complications. |
The prognosis depends on the underlying cause; early treatment of the underlying condition is crucial for preventing complications and preserving vision. |
