Anemia does not usually cause high intraocular pressure. 1. Anemia is a state in which the total volume of red blood cells in the peripheral blood is below the normal range. When anemia occurs, the eye tissue will have insufficient blood volume, microcirculation disorders and a decrease in oxygen content, so the patient with anemia will have dry eyes, astringent eyes, and vision loss, lid conjunctiva pale symptoms. There is also a decrease in albumin, which may be accompanied by edema of the eyelid tissue. Anemia can be seen in aplastic anemia, iron-deficiency anemia, leukemia, systemic lupus erythematosus, liver disease, and so on. 2. However, anemia does not usually lead to elevated intraocular pressure (IOP). High intraocular pressure is affected by many factors, such as mood swings, long reading time, endocrine disorders, high myopia, glaucoma, vascular diseases, etc. For patients with high intraocular pressure, they should have a regular work and rest schedule and avoid staying up late to avoid aggravating the situation of high intraocular pressure. If you have anemia and high intraocular pressure, you should consult a physician to find out the cause of the anemia.
