How to lower the Ocular Pressure without the use of eye drops
Intraocular hypertension is one of the most common diseases affecting the eyes. This develops when the pressure of the aqueous humour is higher than usual. If neglected, hypertension may result in glaucoma, a more serious disease that causes a gradual loss of vision; for this reason, it is vitally important to act as soon as it is detected. It is a completely asymptomatic condition that, in general, is diagnosed during an eye examination. The first therapeutic approach consists in the instillation of eye drops, but unfortunately, they are not effective for all patients. Nutrition and Lifestyle
1) Reduce insulin levels.
People who are obese, diabetic or with high blood pressure are often resistant to insulin, which triggers greater production of this hormone. High insulin levels have been related to ocular hypertension.
To solve the problem, patients are advised to avoid certain foods that can trigger a sudden spike in insulin. These are sugars, cereals (including whole and organic ones), bread, pasta, rice and potatoes.
2) Train often.
Regular physical activity such as aerobics, running, walking, cycling and strength training allows you to lower your insulin level, thus also protecting your eyes from high blood pressure.
Insulin is a hormone that allows the passage of the sugar present in the blood (glucose) to the cells that use it as a source of energy. If you consume this energy with training, your blood sugar is reduced and your insulin levels accordingly. If insulin is low, then there is no hyperstimulation of the sympathetic nervous system of the eye and therefore does not increase intraocular pressure.
Try to train at least 30 minutes a day, three to five times a week.
3) Take food supplements of omega-3 fatty acids. 17 APRIL 2018
MAIN — 21 03 76
Docosahexaenoic acid (DHA) is a type of omega-3 that maintains healthy renal function and prevents increased pressure in the eye.
DHA and the other omega-3s are found in cold-water fats such as salmon, tuna, sardines, herring and molluscs. To increase the intake of DHA, try to eat two or three portions of these fish every week.
Alternatively, you can increase your omega-3 intake by taking fish oil capsules or algae-based supplements. To obtain good results take standard fish oil capsules of 3000-4000 mg per day or choose seaweed supplements with a dosage of 200 mg per day.
4) Eat more foods rich in lutein and zeaxanthin.
Both are carotenes that perform an antioxidant function protecting the body from free radicals. The latter weaken the immune system, resulting in a propensity to infections and damage to the optic nerve.
Lutein and zeaxanthin contribute to lower intraocular pressure by reducing oxidation damage around the optic nerve; this detail is very important because every injury to the optic nerve increases the ocular pressure.
The foods that contain a lot of lutein and zeaxanthin are cabbage, spinach, black cabbage, Brussels sprouts, broccoli and raw egg yolks. You should incorporate one of these foods into every main meal of the day.
5) Avoid trans fats.
As already described above, omega-3 fatty acids are able to reduce intraocular pressure. However, foods with a high trans fat content prevent the omega-3 from working properly and, as a result, eye pressure may increase.
For this reason, you should limit the consumption of foods rich in this type of fat, including industrial or baked goods, fried foods, ice creams, microwave-baked popcorn and ground beef.
6) Eat more antioxidant foods.
Dark-coloured berries such as blueberries and blackberries improve ocular health as a whole, strengthening the capillaries that transport nutrients to the nerves and muscles. This is because dark berries contain antioxidants that strengthen blood vessels, reducing the chances of bleeding and injury.
Try to eat at least a portion of dark berries once a day.
Lipoic acid (ALA) is an antioxidant that is used to prevent and treat many eye disorders, including glaucoma and hypertension. The standard dosage is 75 mg twice a day.
Blueberries are used to improve visual acuity and combat degenerative eye diseases, including hypertension. A study conducted on a particular product containing blueberries and pycnogenol (a pine bark extract) found that these elements are able to lower intraocular pressure.
Grape seed extract is an antioxidant that has been shown to be effective for lowering eye stress due to fixation. It is generally used to improve night vision and combat the signs of ageing.
7) Try marijuana (Cannabis), where this product is legal.
It can be taken in the form of edible, sublingual capsules, tablets or oil for vaporizers. One of the elements of marijuana, cannabidiol (CBD), has no psychotropic effects and is able to lower intraocular pressure. It has been found that a dose of 20-40 mg of CBD is effective in the treatment of ocular hypertension.
8) Learn about why surgery may be necessary.
If hypertension persists, it can damage the optic nerve by triggering a pathological condition called glaucoma. With time, glaucoma leads to blindness. Usually, this disease is treated with a combination of eye drops and oral medications. However, if these treatments do not lead to the desired results, it is necessary to use the operating room to lower the intraocular pressure.
The goal of the intervention is to improve the flow of water humour inside the eye and, consequently, lower the pressure. Sometimes just one operation is not enough to bring the pressure to normal levels and treat glaucoma. In these cases a second retouching is necessary.
There are several procedures that are put in place according to the severity of the situation.
9) Ask your ophthalmologist for some information about draining systems.
These devices are used to treat intraocular hypertension in children and patients with advanced glaucoma. During the procedure, the surgeon inserts a small tube into the eye to facilitate the outflow of the intraocular fluid and, consequently, reduce the pressure.
11) Evaluate laser surgery.
Trabeculoplasty is a procedure that uses a high-intensity laser beam to open the drainage channels blocked inside the eye, allowing the aqueous humour to flow. After surgery, the patient undergoes periodic checks to make sure the procedure has been successful.
Another procedure is called iridotomy. This type of laser is used in people with closed drainage angles. The surgeon practices a small hole in the upper part of the iris to allow the fluid to flow.
If laser iridotomy does not work, then it switches to a peripheral iridotomy. This procedure involves the removal of a small part of the iris to improve the drainage of the aqueous humour. This is a rather rare intervention.
12) Know that you may need a filtration surgery.
Trabeculectomy is a type of intervention that is used as a last resort to treat hypertension that does not respond to eye drops and laser surgery.
During surgery, the surgeon creates an opening in the sclera (the white part of the eye) and removes a small piece of tissue at the base of the cornea. This allows the aqueous humour to flow, thus reducing the pressure in the eye.
One intervenes first on one eye and, weeks later, on the other, if necessary. Sometimes you have to operate several times because the opening may stop or close again.
13) Train to blink every three or four seconds.
People have a tendency to “forget” to wink when they work on the computer, watch television or play video games. This behaviour puts pressure on the eyes.
You can relax and refresh your eyes by winking with conscious effort every three or four seconds for about two minutes. Use a clock to keep the rhythm, if necessary.
Doing so relieves some pressure on your eyes and prepares them to process new information.
14) Cover one eye with the palm of your hand.
This action allows you to relax both the eye and the mind, removing stress and allowing you to blink freely.
Place your right hand on the right eye with your fingers on the forehead and the base of the palm on the cheekbone. Do not apply any pressure.
Hold your hand in this position for 30-60 seconds while winking all the time. Then you discover the eye and repeat the exercise with the left eye.
15) Move your eyes following an imaginary “eight” trajectory.
This exercise strengthens the extrinsic musculature and improves its flexibility. In this way, the eyes are less prone to trauma and hypertension.
Imagine that on the wall in front of you there is a large 8 written horizontally. With your eyes try to outline the number without, however, move your head. Continue this way for a minute or two.
If you have any difficulty imagining a horizontal 8, try drawing it on a large sheet and hang it on the wall. At this point, you can follow the perimeter with your eyes.
16) Practice focusing on near and far objects.
In doing so, strengthen the muscles of the eye and improve your eyesight in general.
Find a quiet place to sit and where there are no distractions. Keep your thumb about 25 cm from you, in front of your eyes and fix it with both eyes.
Hold the fixation on the thumb for 5-10 seconds and then shift the focus to another object that is 3-6 m away. Toggle the fixation between the near and far object for a minute or two.
17) Try doing convergence exercises for How to lower the Ocular Pressure without the use of eye drops
This improves the ability to fix and strengthen the eye muscles.
Stretch out a hand in front of you by pushing your thumb out. Fix your finger with both eyes and move it slowly until it is 8 cm from your face.
Remove your finger again without ever losing fixation. Continue with this exercise for a minute or two.
Inquire about Intraocular Hypertension
18) Know how high intraocular pressure is diagnosed.
This is a difficult problem to recognize since it does not show obvious symptoms such as pain or ocular hyperemia. It is not possible to reach a formal diagnosis only with observation and you must then undergo a complete eye examination. The doctor has several tools to identify hypertension.
Tonometry. This procedure measures intraocular pressure and determines if it is within the normal range. The eye is momentarily desensitized, then an orange dye is instilled to help the doctor take the measurement.
A value equal to or greater than 21 mmHg, in general, indicates the presence of intraocular hypertension. However, there are other conditions that can interfere with this measurement, such as a head injury or an eye or a buildup of blood behind the cornea.
Blowing tonometry. During the procedure, the patient is asked to fix inside an instrument while the doctor illuminates the eye. The instrument sends a quick blast of air directly onto the eye, simultaneously reading the changes in the light reflected from the cornea. The machine translates these changes into a pressure value.
19) Know the causes of intraocular hypertension.
This disorder is associated with ageing, but also with other factors, including:
Hyperproduction of water humour. Aqueous humour is a transparent fluid that is produced by the eye. Its drainage is guaranteed by the structure of the trapezoid. If the eye produces too much liquid, the internal pressure increases.
Insufficient drainage of the aqueous humour. If the liquid does not flow properly, it accumulates by increasing the internal pressure.
Drugs. Some medicines (such as cortisone) can cause intraocular hypertension, especially in individuals who already have other risk factors.
Ocular trauma. Any kind of trauma or irritation to the eye can alter the balance between production and outflow of the aqueous humour and lead to an increase in pressure.
Other eye diseases. Eye hypertension is often related to other organ problems, such as pseudoexfoliation syndrome (PEX), gerontoxon and pigmentary glaucoma.
20) Become aware of the risk factors for ocular hypertension.
Anyone can develop this condition, but some studies have shown that people belonging to the categories listed below are at greater risk:
Individuals familiar with glaucoma and intraocular hypertension;
People with reduced central corneal thickness.
