Evaluation and Treatment of Subconjunctival Hemorrhage
Subconjunctival hemorrhage requires no specific treatment and will resolve spontaneously within 1-2 weeks in most cases. Observation and patient reassurance are the primary management approaches for this common and benign condition 1.
Evaluation
Clinical Presentation
- Sudden onset of painless, bright red blood patch on the white of the eye
- Usually unilateral but can be bilateral
- No visual changes
- May be accompanied by mild irritation or foreign body sensation
- Often noticed upon waking or after episodes of coughing/straining
Risk Factors to Assess
Trauma - most common cause in younger patients 2
- Direct eye injury
- Foreign body
- Vigorous eye rubbing
Contact lens wear - common in younger patients 2
- Extended wear
- Improper insertion/removal
Systemic conditions - more common in elderly 2
- Hypertension
- Diabetes
- Arteriosclerosis
Medications
Other factors
- Valsalva maneuvers (coughing, vomiting, straining)
- Conjunctival vessel fragility
When to Consider Further Workup
Further evaluation is warranted only in specific circumstances:
- Recurrent or persistent subconjunctival hemorrhages
- Bilateral extensive hemorrhages
- Associated with other bleeding manifestations
- Suspicion of child abuse
- Suspected ocular or orbital malignancy
Treatment
Primary Management
- Observation - most cases resolve spontaneously within 1-2 weeks
- Patient reassurance about the benign nature of the condition
- Artificial tears for mild irritation (preservative-free formulations)
- Cold compresses for the first 24-48 hours to reduce discomfort
Specific Scenarios
For Traumatic Subconjunctival Hemorrhage
- Assess for associated ocular injuries (corneal abrasion, hyphema, etc.)
- Rule out globe perforation if high-velocity trauma
- Consider protective eyewear to prevent recurrence
For Contact Lens-Related Hemorrhage
- Temporary discontinuation of contact lens wear until resolved
- Review proper contact lens hygiene and handling
- Consider changing lens type or wearing schedule
For Medication-Related Hemorrhage
- Do not discontinue anticoagulants without consulting the prescribing physician 1
- Benefits of anticoagulation typically outweigh the risk of benign subconjunctival hemorrhage
For Hypertension-Related Hemorrhage
- Blood pressure measurement
- Referral to primary care for hypertension management if elevated
Follow-up
When to Return
- Routine follow-up is not necessary for simple subconjunctival hemorrhage
- Patients should return if:
- Vision changes develop
- Pain develops or worsens
- Hemorrhage doesn't resolve within 2-3 weeks
- New hemorrhages develop while the initial one is resolving
Patient Education
- Explain the benign nature of the condition
- Advise that the blood will gradually change color (like a bruise) before clearing
- Warn that the hemorrhage may appear to worsen before improving as blood spreads
- Reassure that vision is not affected
Special Considerations
Recurrent Subconjunctival Hemorrhage
For patients with recurrent episodes, consider:
- Blood pressure monitoring
- Coagulation studies (though studies show bleeding disorders are rarely the cause) 5
- Evaluation of medication effects
- Assessment for systemic vascular diseases
Extensive or Bilateral Hemorrhage
May warrant investigation for:
- Severe hypertension
- Blood dyscrasias
- Anticoagulant overdose 3
- Systemic bleeding disorders (though these are rare causes) 5
Pediatric Patients
- Consider non-accidental trauma in unexplained cases
- Evaluate for connective tissue disorders in recurrent cases
Common Pitfalls to Avoid
- Unnecessary antibiotic prescriptions (not effective for subconjunctival hemorrhage)
- Discontinuing necessary anticoagulants without medical consultation
- Failing to recognize when hemorrhage is a manifestation of serious systemic disease
- Overlooking associated ocular trauma in traumatic cases
- Excessive testing in isolated, non-recurrent cases
Remember that while alarming in appearance, subconjunctival hemorrhage is typically a benign, self-limiting condition that resolves without specific intervention.
