Treatment for Moderate Subconjunctival Hemorrhage Secondary to Trauma
Moderate traumatic subconjunctival hemorrhage requires no active treatment beyond observation and reassurance, as it resolves spontaneously within 1-3 weeks; however, a thorough examination to exclude associated serious ocular injuries is mandatory. 1, 2
Immediate Management Approach
Primary Assessment Requirements
Visual acuity must be documented immediately in every patient with traumatic subconjunctival hemorrhage, as visual acuity less than 20/40 increases the probability of additional serious ocular injuries by more than 5-fold (OR 5.27). 1
Perform a comprehensive ocular examination to identify coexisting injuries, as 42.7% of eyes with traumatic subconjunctival hemorrhage have additional damage, rising to 66.2% when visual acuity is reduced. 1
Specifically evaluate for:
Treatment Protocol
No active intervention is required for the subconjunctival hemorrhage itself. 3, 4 The blood reabsorbs spontaneously without treatment.
Artificial tears or lubricating drops may be used for symptomatic relief if the patient experiences foreign body sensation or discomfort. 3
Cold compresses can be applied in the first 24-48 hours if there is associated periocular swelling, though this does not accelerate hemorrhage resolution. 3
Avoid aspirin and NSAIDs unless medically necessary, as these may theoretically prolong bleeding, though evidence is limited. 4
Critical Pitfalls to Avoid
Never dismiss traumatic subconjunctival hemorrhage without measuring visual acuity and performing a complete examination, as this is the most common error leading to missed serious injuries. 1 Eyes with normal visual acuity (20/20-20/40) still have a 27.1% rate of additional injuries requiring specialized care. 1
Do not assume the hemorrhage is the only injury based on its dramatic appearance—the bright red blood often distracts from more serious underlying pathology. 1, 2
Recurrent or persistent hemorrhages beyond 2-3 weeks warrant investigation for underlying systemic conditions (hypertension, coagulopathy) or, rarely, occult malignancy. 5, 4
Follow-Up Strategy
Routine follow-up is unnecessary for isolated subconjunctival hemorrhage with normal examination findings and normal visual acuity. 3, 4
Ophthalmology referral is indicated if:
Patient education should emphasize that the hemorrhage will worsen in appearance over 24-48 hours as blood spreads, then gradually fade from red to yellow-brown over 1-3 weeks. 3
Special Considerations in Pediatric Trauma
In children of all ages, including infants, 94-97% of traumatic subconjunctival hemorrhages are due to accidental trauma or ocular surface inflammation. 2 However, all children with subconjunctival hemorrhage must be examined for other signs of trauma (ocular and non-ocular) to identify potential non-accidental injury. 2
