Hypertension is a very common condition where there is an elevation in blood pressure which can lead to changes in the retina. The retina is the complex, light-sensitive, neural tissue in the back of the eye that contains highly-specialized photoreceptor cells called rods and cones. Leakages of blood and other fluids from hypertension can disrupt the retina and how it works resulting in potentially permanent vision loss, called hypertensive retinopathy.
Since this disease can cause partial blindness, early diagnosis and treatment is essential. That's one reason why it is important to have your eyes examined periodically by an eye doctor. Another reason is that Hypertension is a major risk factor for developing glaucoma. If you have hypertension or if you have a family history of hypertension, you should have your eyes checked yearly.
