Red blood spots in the corners of the patient’s eyes are most often caused by subglobular conjunctival hemorrhage, which can be associated with a history of trauma, hypertension, and other related conditions.
Subconjunctival hemorrhage can result when the patient’s subconjunctival blood vessels rupture and permeability increases. Because of the loose connective tissue underneath, the hemorrhage tends to turn into a flaky erythema that is initially bright red and can gradually change to brown.
Relevant medical history leading to subconjunctival hemorrhage includes trauma (e.g., head crush injuries, ocular trauma), hypertension, conjunctival inflammation, atherosclerosis, blood disorders (e.g., hemophilia), nephritis, etc. Subconjunctival hemorrhage can also be caused by the patient’s coughing violently.
Patients with significant subconjunctival hemorrhage are advised to seek prompt medical attention to evaluate their condition and follow medical advice.
