In older adults, subconjunctival hemorrhages can happen due to increased fragility of blood vessels or due to minor trauma, such as rubbing the eye or sneezing.Age-related changes in blood vessel elasticity and the thinning of tissues can also make older adults more susceptible. Other triggers include sudden increases in blood pressure, heavy lifting, or taking certain medications that affect blood clotting.
4. When a Red Eye Patch Is a Sign of High Blood Pressure or Blood Thinner Issues
High blood pressure can increase the risk of subconjunctival hemorrhages by putting extra pressure on blood vessels, making them more likely to break. A sudden spike in blood pressure, even if temporary, can lead to these types of eye hemorrhages.
Similarly, people taking blood thinners may experience these hemorrhages more frequently. Blood thinners can affect how blood clots, making it easier for bleeding to occur even with minor vascular trauma.
5. Red Flag Symptoms That Mean You Should Go to the ER Right Now
While most subconjunctival hemorrhages are benign, certain symptoms warrant immediate medical attention. If the red patch is accompanied by pain, vision changes, or if the hemorrhage is very large, it is advisable to seek emergency care.
Additionally, if your partner experiences severe headaches, dizziness, or other neurological symptoms along with the hemorrhage, these could be signs of more serious underlying conditions such as a stroke or significant trauma.
