Retinopathy is a condition that affects the eyes, specifically the retina, which can lead to vision problems or even blindness if not treated. But what exactly is retinopathy, and why should you care? Retinopathy occurs when the blood vessels in the retina become damaged, often due to diabetes or high blood pressure. This damage can cause the vessels to leak fluid or blood, leading to vision issues. Diabetic retinopathy is one of the most common forms, affecting millions worldwide. Early detection and treatment are crucial to prevent severe vision loss. Understanding the symptoms, causes, and treatments can help you take better care of your eyes. Ready to learn more? Let's dive into 31 essential facts about retinopathy that everyone should know.
