Subconjunctival Hemorrhage in Patients with Hypermobile EDS

Subconjunctival hemorrhage can be alarming when it appears as a bright red patch on the white of the eye. For people with hypermobile Ehlers-Danlos syndrome (hEDS), this condition may occur more frequently or with less obvious triggers. Understanding why subconjunctival hemorrhage happens in hEDS, what it means, and how to manage it can help patients and caregivers respond calmly and effectively.
Subconjunctival hemorrhage happens when a tiny blood vessel breaks just beneath the clear surface covering the white part of the eye (the conjunctiva). Blood leaks out and becomes trapped, creating a red or dark patch. It looks dramatic but usually does not cause pain, vision changes, or serious damage.
Common causes include:
Sudden increases in pressure from coughing, sneezing, or straining
Minor eye trauma or rubbing
High blood pressure or blood-thinning medications
In most cases, the hemorrhage resolves on its own within one to two weeks.
Hypermobile EDS is a connective tissue disorder that affects collagen, a protein that provides strength and elasticity to skin, joints, blood vessels, and other tissues. In hEDS, collagen abnormalities make blood vessels more fragile and prone to rupture.
This fragility means that even minor stresses can cause blood vessels in the eye to break, leading to subconjunctival hemorrhage. Some factors that increase risk in hEDS include:
Frequent joint dislocations or injuries that increase strain on blood vessels
Easy bruising and fragile skin indicating overall vascular fragility
Use of medications like aspirin or NSAIDs that affect clotting
Episodes of intense coughing or vomiting, which raise pressure inside blood vessels
Patients with hEDS may notice subconjunctival hemorrhages appearing without clear injury or strain, which can be unsettling but is often part of the condition.
The hallmark sign is a bright red patch on the white of the eye. It may cover a small or large area and sometimes looks like a blood blister. Other symptoms are usually absent, but some people report mild irritation or a scratchy feeling.
Important points to watch for:
No pain or vision changes usually means the hemorrhage is harmless
If the redness spreads or is accompanied by pain, vision loss, or discharge, seek medical care immediately
Recurrent hemorrhages should be discussed with a healthcare provider to rule out other causes
Treatment focuses on reassurance and protecting the eye while the blood is reabsorbed naturally. Here are practical tips:
Avoid rubbing or touching the eye to prevent further irritation
Use lubricating eye drops if the eye feels dry or scratchy
Apply a cold compress briefly if there is mild swelling or discomfort
Monitor blood pressure and manage any underlying conditions that increase bleeding risk
Discuss medication use with a doctor, especially blood thinners or supplements affecting clotting
Most hemorrhages clear up within 7 to 14 days without treatment. If bleeding recurs frequently or lasts longer, a healthcare provider may recommend further evaluation.
While subconjunctival hemorrhage is usually harmless, certain situations require prompt attention:
Sudden vision changes, pain, or discharge from the eye
Hemorrhages that do not improve after two weeks
Frequent or large hemorrhages without clear cause
Signs of systemic bleeding or bruising elsewhere on the body
In people with hEDS, it is important to maintain regular follow-ups with healthcare providers familiar with the condition. They can help monitor vascular health and adjust treatments to reduce bleeding risks.
Taking care of eye health can reduce the chance of subconjunctival hemorrhage and other complications:
Protect eyes from injury by wearing sunglasses or protective eyewear during activities
Manage allergies and avoid rubbing eyes excessively
Maintain good hydration and nutrition to support tissue health
Control blood pressure and avoid smoking, which can weaken blood vessels
Inform all healthcare providers about hEDS to ensure safe medication choices
