H11.433 Conjunctival hyperemia, bilateral

Name of the Condition

• Conjunctival hyperemia, bilateral
• Also known as red eye, ocular injection

Summary

Conjunctival hyperemia, bilateral, is characterized by the redness of both eyes caused by increased blood flow in the conjunctival vessels. This condition often results in a bloodshot appearance and is commonly associated with irritation or infection.

Causes

• Allergies (e.g., pollen, pet dander)
• Viral or bacterial infections (e.g., conjunctivitis)
• Dry eyes
• Eye strain or fatigue
• Exposure to irritants (e.g., smoke, dust)

Risk Factors

• Seasonal allergies
• Frequent use of contact lenses
• Extended screen time
• Poor eyelid hygiene
• Exposure to polluted environments

Symptoms

• Redness in both eyes
• Tearing or watery eyes
• Itchiness or burning sensation
• Swollen eyelids
• Sensitivity to light

Diagnosis

• Physical examination by an eye care professional
• Reviewing medical history and symptoms
• Slit-lamp examination to assess the extent of redness
• Possible allergy testing, if allergies are suspected

Treatment Options

• Artificial tears or lubricating eye drops to soothe irritation
• Antihistamine or mast cell stabilizer drops for allergies
• Antibiotic eye drops if bacterial infection is present
• Warm compresses to alleviate discomfort

Prognosis and Follow-Up

• Generally good, especially when underlying causes like allergy or infection are treated.
• Most cases resolve without complications if properly managed.
• Regular eye exams to monitor eye health in persistent cases.

Complications

• Chronic discomfort if left untreated
• Potential vision changes due to untreated underlying conditions

Lifestyle & Prevention

• Maintain good eye hygiene
• Limit screen time and take regular breaks
• Use protective eyewear in dusty or smoky environments
• Manage allergies with antihistamines during high pollen seasons

When to Seek Professional Help

• Severe or sudden eye pain
• Significant vision changes
• Redness that doesn’t improve with standard treatments
• Signs of an eye infection (e.g., thick discharge, severe swelling)

Tips for Medical Coders

• Ensure bilateral presentation is accurately documented.
• Verify linkage to specific etiological factors for precise coding.
• Double-check for any coding overlaps with primary conditions like conjunctivitis.
