The degree of redness varies from mild to pronounced. People may also experience tearing or discomfort. Exam findings help determine the underlying cause.
read more about injected conjunctiva ...Dryness, allergies, and viral infections are common triggers. Bacterial infections can produce thicker discharge along with redness. Chemical irritation or foreign bodies also increase surface vessel dilation. Conditions such as uveitis create a deeper pattern of redness. Identifying irritants or recent exposures helps pinpoint the cause.
Redness is the primary sign. People may feel burning, stinging, or grittiness. Watery discharge often appears in viral and allergic cases. Light sensitivity may increase if deeper structures are involved. Vision is usually clear unless swelling or discharge affects the surface.
A slit lamp exam evaluates vessel patterns, discharge type, and surface staining. Doctors assess whether redness is superficial or deeper. History clarifies exposure, onset, and associated symptoms. Additional tests may be done if inflammation is suspected. Diagnosis depends on linking findings with patient history.
Treatment focuses on the cause. Lubrication helps dryness-related redness. Allergic cases respond to antihistamine drops. Viral infections resolve with supportive care. Bacterial infections require antibiotic drops. Persistent or painful redness needs prompt evaluation.
No. Many cases relate to irritation or dryness.
Yes. Allergies produce prominent surface vessel dilation.
Usually not, unless swelling or discharge covers the surface.
Seek care for pain, light sensitivity, or worsening redness.
