How to Treat Subconjunctival Hemorrhage: Treatment Options and Eye Drops

A subconjunctival hemorrhage is a bruise on the eye’s surface that clears on its own within one to two weeks; no drop makes it fade faster.

A bright red patch on the white of the eye looks worse than it is — blood under the clear membrane behaves like a bruise and fades on a similar schedule. Treatment options and eye drops relieve the gritty, itchy surface while time does the actual clearing.

Subconjunctival Hemorrhage Treatment: What Works And What Doesn’t

An uncomplicated subconjunctival hemorrhage needs no treatment; blood is reabsorbed on its own, usually within one to two weeks, though some cases take several weeks. Most patches appear without warning or follow a cough, sneeze, strain, or eye rubbing, and can look bigger the next morning as blood spreads under the membrane overnight. Nothing sold at a pharmacy dissolves the pooled blood or shortens that timeline — these options only make the eye feel better while it heals.

• Observation: Normal activities can generally continue.
• Cold compress: May ease mild discomfort; does nothing for the bleeding.
• Lubricating gel or ointment: Helps persistent surface irritation, including overnight. Ask a pharmacist which product fits.
• Over-the-counter pain relievers: Reasonable for discomfort, with pharmacist advice when appropriate.
• An eye patch: Not required for uncomplicated cases.

Antibiotic, steroid, redness-relief, and blood-vessel-shrinking drops are not routine for an uncomplicated hemorrhage; a clinician may prescribe something different only after an exam finds a separate injury, infection, or inflammation.

Which Eye Drops Help And Which Do Nothing?

Artificial tears are the only drops that make sense, and they act on the eye’s surface rather than the blood. The American Academy of Ophthalmology is blunt: the Academy’s eyedrop guidance states that drops do not treat the hemorrhage and that time is the treatment.

Mayo Clinic points to artificial tears for an itchy feeling — the honest ceiling for any over-the-counter drop. Preservative-free single-use vials cost a little more and are worth it when you dose often or your eye surface is sensitive.

Technique matters more than the brand:

1. Wash your hands and confirm the product is an eye preparation inside its expiration date.
2. Pull down the lower lid to form a pocket and squeeze the labeled dose into it.
3. Keep the tip off the eye, lashes, and skin.
4. Close the eye gently instead of rubbing, then recap the bottle right away.
5. Never share drops, and store them per the package directions.

Choosing a product is the fiddly part. This roundup of the best eye drops for subconjunctival hemorrhage compares preservative-free picks and thicker gels.

When Does A Red Eye Need A Doctor?

A red eye needs prompt attention when it arrives with pain, vision changes, or recent injury, because the bleeding may not be the whole story. An uncomplicated hemorrhage does not hurt and does not blur vision. Have it looked at if you notice any of these:

• Pain, or vision that is reduced, blurred, or doubled
• Recent trauma, a penetrating injury, or a possible foreign body
• Symptoms that keep getting worse
• Repeated hemorrhages, or new ones in both eyes
• Easy bruising, bleeding gums, or other unexplained bleeding
• A bleeding or clotting disorder, or blood pressure that hasn’t been checked recently
• A patch still present after about two weeks

Trauma calls for extra caution, since subconjunctival blood can sit alongside scleral or orbital injury. A clinician will usually check visual acuity, examine the eye with a slit lamp, and measure blood pressure when appropriate.

One safety point outweighs the rest: never stop aspirin, warfarin, or another anticoagulant on your own. Those medicines can raise bleeding tendency, but changing them without your prescriber’s direction can create a larger risk than the red patch.

If the visit includes dilating drops, plan on roughly two to three hours of blurred vision afterward and line up a ride home.
