Arjuna ↔ Subconjunctival Haemorrhage

Arjuna's classical picture -- a sudden, painless, sharply demarcated red patch that resolves like a bruise over one to two weeks -- maps well onto isolated subconjunctival haemorrhage, usually the most benign finding in this unit. The clinically load-bearing content here is not the correspondence itself but the trauma-related red flags (open globe, orbital fracture, retrobulbar haemorrhage) and the systemic recurrence workup that the classical account, focused on the local finding, does not independently supply a framework for.

IN PLAIN LANGUAGE

A sudden bright red patch on the white of the eye, usually painless and discovered on waking, caused by a small burst blood vessel under the conjunctiva. It is usually harmless and resolves on its own over one to two weeks, changing colour as it heals, much like a bruise on the skin.

Both classical Ayurveda and modern medicine recognize this as usually benign and self-resolving, needing only reassurance. Modern medicine's specific contribution is a codified list of red flags after trauma that distinguish a harmless bleed from a genuine orbital emergency, and a systematic workup (blood pressure, anticoagulants, bleeding disorder) for recurrence that the classical account does not detail independently.

WHEN TO SEEK CARE

After any injury, seek emergency care immediately if you cannot see the back edge of the blood, if the blood goes all the way around the eye, or if there is bulging of the eye, painful or restricted eye movement, reduced vision, or pain out of proportion to a simple bruise. Without injury, recurrent or bilateral episodes should prompt a blood-pressure check and a review of any blood-thinning medication.

🔴 REFER IMMEDIATELY

An extensive haemorrhage whose posterior margin cannot be visualised, or a full 360-degree haemorrhage, after trauma
Associated proptosis, restricted or painful eye movement, or reduced visual acuity after trauma
Pain clearly out of proportion to what a simple subconjunctival bleed should produce
Recurrent or bilateral spontaneous haemorrhage without a trauma history
Haemorrhage accompanied by discharge, photophobia, rapid bilateral spread, or preauricular lymphadenopathy (suggests viral haemorrhagic conjunctivitis, not isolated Arjuna)
Any red-flag feature after trauma listed above
Recurrent or bilateral spontaneous episodes
Any accompanying discharge, photophobia, or systemic signs suggesting viral haemorrhagic conjunctivitis

Never do this

Do not stop or adjust a patient's anticoagulant or antiplatelet medication unilaterally based on a subconjunctival haemorrhage finding -- that decision belongs to the physician who prescribed it. Do not reassure away a post-traumatic haemorrhage with any of the listed red-flag features without urgent evaluation for open globe injury, orbital fracture, or retrobulbar haemorrhage.

🟢 SUITABLE FOR ROUTINE / COLLABORATIVE CARE

AYURVEDA SCOPE

Reassurance, cooling Rakta-Pitta pacifying local measures, and lubrication for an isolated, trauma-negative episode with none of the red-flag features listed above.

MODERN MEDICINE SCOPE

The trauma red-flag examination excluding open globe injury, orbital fracture, or retrobulbar haemorrhage; the blood pressure, anticoagulant-review and bleeding-disorder workup for recurrent or bilateral episodes.

COLLABORATIVE SCOPE

Reassurance and observation for isolated benign episodes can be delivered by either system; any trauma history or recurrence pattern should trigger the modern workup described here before either system's local, reassurance-based approach is used.
