H11.43 Conjunctival hyperemia

Name of the Condition

• Conjunctival hyperemia

Summary

Conjunctival hyperemia is the medical term for redness of the conjunctiva, the clear tissue covering the white part of the eye and the inside of the eyelids. This condition occurs when small blood vessels in the conjunctiva become more visible due to increased blood flow. It is a common sign of ocular irritation or inflammation.

Causes

Conjunctival hyperemia can result from various factors, including infections (bacterial or viral), allergic reactions, dry eye syndrome, exposure to irritants like smoke or dust, and eye strain. Underlying conditions such as conjunctivitis or uveitis may also cause this symptom.

Risk Factors

• History of allergies or asthma
• Use of contact lenses
• Frequent exposure to environmental irritants (e.g., smoke, dust, chemicals)
• Pre-existing eye conditions like dry eyes or blepharitis
• Prolonged screen time or eye fatigue

Symptoms

• Redness in the white of the eye
• Mild irritation or discomfort
• Watery eyes
• Itching or burning sensation
• Sensitivity to light (in some cases)

Diagnosis

Diagnosis typically involves a physical examination of the eye by a healthcare professional. A slit-lamp examination may be used to assess the conjunctiva and rule out other conditions. Additional tests, such as conjunctival swabs or allergy assessments, might be performed if an underlying cause is suspected.

Treatment Options

Treatment depends on the underlying cause:

• For infections: Antibiotic or antiviral eye drops
• For allergies: Antihistamine or mast cell stabilizer drops
• For dry eyes: Artificial tears or lubricating eye drops
• For irritation: Avoidance of triggers and warm compresses

Prognosis and Follow-Up

Prognosis is generally good, especially when the underlying cause is identified and treated. Most cases resolve with appropriate management. Follow-up may be recommended if symptoms persist or worsen, particularly if an infection or chronic condition is present.

Complications

In rare cases, untreated or severe conjunctival hyperemia may lead to corneal damage, vision changes, or spread of infection. Chronic redness could indicate an underlying condition requiring further evaluation.

Lifestyle & Prevention

• Avoid known allergens or irritants
• Practice good eye hygiene (e.g., clean contact lenses properly)
• Use lubricating eye drops for dry eyes
• Take breaks during prolonged screen use
• Wear protective eyewear in dusty or smoky environments

When to Seek Professional Help

Seek medical attention if redness is severe, accompanied by pain, vision changes, discharge, or light sensitivity. Persistent symptoms lasting more than a few days also warrant evaluation.

Tips for Medical Coders

When coding for conjunctival hyperemia (H11.43), ensure documentation specifies the condition and any associated factors (e.g., laterality, underlying cause). Verify that the diagnosis aligns with clinical findings and that the code is used appropriately for billing and record-keeping purposes.
