H11.433 Conjunctival hyperemia, bilateral

ICD10CM code

#### 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)
