Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [1] [2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg.
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye. [1] [3] In hypertensive encephalopathy, generally the blood pressure is greater than 200/130 mmHg. [1] Occasionally it can occur at a BP as low as 160/100 mmHg. [4]
Hypertensive retinopathy is damage to the retina and retinal circulation due to high blood pressure (i.e. hypertension).
The body is affected in different ways depending on the type of exposure. Central nervous system toxicity is caused by short exposure to high partial pressures of oxygen at greater than atmospheric pressure. Pulmonary and ocular toxicity result from longer exposure to increased oxygen levels at normal pressure.
The combination of anemia and low blood pressure means that the blood is carrying less oxygen to the tissues. The optic nerve can be at very high risk for damage from insufficient blood supply due to swelling (from lack of oxygen) in a confined bony space resulting in a compartment syndrome .
