What causes bleeding in the retina?

The main causes of retinal hemorrhage are as follows: 1. Eye diseases: Conditions such as retinopathy and high myopia can damage the blood vessels in the retina, leading to bleeding. 2. Systemic diseases: Systemic conditions like hypertension and diabetes can affect vascular health, causing rupture and bleeding of the retinal blood vessels. 3. Unhealthy lifestyle habits: Smoking and excessive alcohol consumption may damage blood vessels, reduce their elasticity, and increase the risk of retinal hemorrhage. 4. Medication factors: Certain medications, such as anticoagulants and penicillamine, may cause retinal hemorrhage as an adverse reaction. 5. Environmental factors: In high-altitude environments, where oxygen levels are lower, ocular blood vessels may rupture, resulting in retinal hemorrhage.
