Intraocular pressure is called the pressure inside the eyeball. Fluids join the eyeball to provide food to preserve the shape of the eye while they are normal physiologic. A dysfunctional eye drainage system often causes the fluid to increase, leading to pressure in the eye (ocular hypertension).The growth of glaucoma also results in chronic greater intraocular pressure an eye condition where persistently elevated eye pressure affects the optic nerve and contributes to loss of vision. In comparison to glaucoma with optic nerve damage and vision disorder, ocular hypertension is typically asymptomatic.
Science has shown that approximately 10% of people with untreated eye hypertension experience primary open-angle glaucoma over five years. For these people, it is therefore important to periodically control the eye pressure so that they are unable to develop glaucoma.
What causes ocular hypertension?
The eye constantly makes a clear fluid called watery humor, which enters to provide nutrients in the front portion of the eye. Simultaneously an equal volume of fluid flows out to hold an eye pressure. The fluid builds up and the intraocular pressure increases, leading to ocular hypertension, as this drainage system fails to operate correctly.
Ocular hypertension is typically caused by a blockage in the drainage channels of the eye or the overproduction of aqueous humor. Ocular hypertension can also be caused by eye injuries or some diseases of the eye. Some medicines can also increase intraocular pressure, such as steroids.
What are the symptoms and signs of Ocular Hypertension?
There are no signs in most people with ocular hypertension. Regular eye exams by an ophthalmologist are also very important to avoid high-pressure damage to the optic nerve.
What are the ocular hypertension risk factors?
Eye blood pressure may grow at any age but with age the prevalence increases. People 40 years of age or older are more prone to eye hypertension.
High risk is identified by African Americans and Hispanics. Non-white is a major indicator for glaucoma, according to the Collaborative Initial Glaucoma Treatment Study, CIGTS.
People who are very close-sighted (myopic) or have certain disorders such as diabetes or high blood pressure are more vulnerable to ocular hypertension. In addition, individuals with a pigment scatter syndrome (an eye condition that occurs in the aqueous humor when iris cells float) and exfoliation syndrome, which are caused by an accumulation in the ocular tissues of an irregular extracellular fibrillar material, are at risk. A significant risk factor is often a family history of hypertensive eyes or glaucoma.
Interestingly, although the risk of ocular hypertension increases through systemic hypertension (high blood pressure), low blood pressure can induce glaucoma by reducing the eye’s infusion and blood supply to the eye and optic nerves.
Ocular Hypertension Treatment
Ocular Hypertension will put you at risk for glaucoma. For those with eye hypertension, diligent and regular monitoring is recommended.
Medication (eye drops) medication such as a Careprost can be used to reduce the pressure in your eye.
Your eye doctor should prepare follow-up consultations with the specific prescription you are taking, as it can take 6-8 weeks to make those medications e.g. latanoprost, travoprost, bimatoprost truly effective.
Are Home Ocular Hypertension Remedies Effective?
It’s extremely important for your ophthalmologist to correctly apply for the medicine and to obey your doctor’s instructions to help lower your eye pressure (see Medical Care and Medications). Further intraocular pressure could not lead to optic nerve damage and irreversible vision loss. This is not the case (for example, glaucoma).
