Background
- Bleeding of the conjunctival vessels into the subconjunctival space
- Can be spontaneous or related to trauma
- Spontaneous can be secondary to anticoagulation, bleeding diathesis, etc.
- If large and associated with trauma, need to maintain suspicion for occult globe rupture (obscured by hemorrhage)[1]
- Bilateral and recurrent subconjunctival hemorrhage should have bleeding diathesis workup
Clinical Features
- Painless
- No effect on vision
- May recall a history of mild trauma or valsalva
- Examination
- Fresh red blood on a white sclera with clear borders[1]
- Masks the conjunctival vessels

^Emergent diagnoses ^^Critical diagnoses
Evaluation
- Clinical diagnosis
- Consider fluorescein staining to evaluate for corneal injury if suggested by history or if patient complains of pain[1]
Management
- Reassurance (will generally resolve within 10-14d)[1]
