What Helps with High Eye Pressure?

The fundamental approach for managing elevated eye pressure is adherence to the treatment determined through examination, and regular monitoring. No food, herbal product, or exercise can replace glaucoma treatment. If there is severe eye pain, sudden blurred vision, and nausea, an urgent evaluation for an eye pressure attack is required.

Elevated eye pressure is a serious condition that can affect eye health and may lead to permanent vision loss if neglected. It is encountered more frequently after the age of 40 and can be managed when identified early. Because it may progress without obvious symptoms, some people experience vision loss before realising there is a problem.

Ocular pressure, also known as intraocular pressure, is the pressure created by the balance between the production of aqueous humor, a clear fluid that fills the anterior chamber of the eye, and its elimination from the eye. Aqueous humor is continuously produced in the ciliary body and maintains the anterior chamber, which is essential for nourishing the cornea and lens. Once this fluid performs its function, it is eliminated from the eye through a drainage system called the trabecular network. If the balance between the amount of fluid produced and the amount eliminated is maintained, ocular pressure remains within normal limits. However, if a blockage occurs in the drainage canals or if the production of fluid increases, ocular pressure rises, and this is referred to as elevated ocular pressure. Elevated ocular pressure can exert pressure on the optic nerve, which is located in the posterior part of the eye, and can lead to damage to nerve fibers.

Elevated intraocular pressure is a major risk factor for glaucoma, a serious eye disease sometimes described in Turkish as “göz tansiyonu hastalığı” or “karasu”. Glaucoma is a leading cause of irreversible blindness worldwide. High pressure does not always lead to glaucoma: some people have elevated pressure without optic nerve damage, a condition called ocular hypertension. Conversely, optic nerve damage may occur despite pressure within the usual range; this is called normal-tension glaucoma. Regular monitoring is therefore important for early detection. The ophthalmologist determines follow-up intervals according to age, family history, individual risk factors and examination findings.

One of the most dangerous aspects of ocular hypertension, and glaucoma, is that in many cases, it progresses silently for a long time without any symptoms. Specifically, in what is known as chronic open-angle glaucoma, which is the most common type of glaucoma, patients may not experience any complaints for years. Vision loss typically begins in the periphery, i.e., the peripheral visual field, and central vision is usually the last area to be affected, so a person may not notice any problems during their daily activities. The fact that a person does not experience any changes when reading books or using a phone, for example, can mislead them. Because peripheral vision loss progresses slowly, people often do not realize the condition has advanced until it reaches later stages. Therefore, high ocular pressure and glaucoma are referred to in medical literature as “silent thieves.” The absence of symptoms underscores the importance of regular eye examinations.

With that being said, serious symptoms may arise when there is a sudden and significant increase in eye pressure. This condition, known as acute angle closure glaucoma, can cause eye pressure to rapidly reach dangerous levels in a very short period. In this type of presentation, severe eye pain, intense headache on the same side, nausea and vomiting, noticeable redness in the eye, seeing colored halos around light sources, and sudden, severe blurred vision may occur. The eye may become hardened, and sensitivity may increase when touched. This type of attack requires urgent medical intervention, and delays in treatment may lead to permanent vision loss. Apart from acute attacks, some patients in chronic conditions may occasionally describe mild eye fatigue, headaches, or a vague feeling of discomfort in the eye area, but these symptoms are often overlooked because they are not specific to eye pressure. Seeking immediate consultation with an eye doctor is the most accurate step for early diagnosis, in any eye complaint.

The factors that can cause elevated intraocular pressure are quite diverse, and often multiple factors play a role simultaneously. The most fundamental cause is dysfunction within the eye’s drainage system. The structure known as the trabecular meshwork, which is responsible for expelling fluid from the eye, can naturally lose its effectiveness with age. In this situation, the fluid begins to accumulate within the eye, leading to an increase in pressure. Genetic predisposition also plays a significant role in elevated intraocular pressure; individuals with a family history of glaucoma or intraocular pressure are at a clearly higher risk of experiencing this condition. The progression of age, particularly being over 40, is a significant risk factor in itself. In addition, ethnic origin can also have an effect on the risk; it is known that the frequency of glaucoma is higher in some populations.

Systemic diseases are among the important factors that can affect eye pressure. Diabetes, systemic hypertension (high blood pressure), and cardiovascular diseases can increase the risk of elevated intraocular pressure. Advanced myopia (difficulty seeing distance) or hyperopia (difficulty seeing near) are also associated with an increased risk of glaucoma. The use of medications can also have a direct effect on eye pressure, especially long-term use of corticosteroids (cortisone), whether in the form of eye drops, oral medication, or inhaler. Eye injuries, previous eye surgeries, intraocular inflammation (uveitis), and certain eye tumors are also other reasons that can lead to an increase in eye pressure. Furthermore, studies have shown that long periods of holding the head in a downward position, excessive caffeine consumption, and wearing very tight ties can also temporarily increase intraocular pressure.

Intraocular pressure is generally considered to be within the normal range at 10 to 21 mmHg (millimetres of mercury). Goldmann applanation tonometry is a commonly used method of measurement. However, this range does not mean the same thing for everyone. Corneal thickness affects interpretation: measurements may underestimate pressure in a thin cornea and overestimate it in a thick cornea. Measuring corneal thickness, called pachymetry, is therefore an important part of assessment. Pressure also fluctuates naturally during the day and may be higher in the morning and lower in the evening. Repeated measurements at different times can provide more reliable information than a single reading.

In ophthalmology evaluations, it is not sufficient to simply look at the pressure readings; the eye doctor considers this value together with the condition of the optic nerve, results from visual field testing, measurements of the retinal nerve fiber layer thickness (OCT), and the patient’s overall risk profile. In some individuals, even when the eye pressure is above 21 mmHg, there may be no damage to the optic nerve; this condition is referred to as ocular hypertension, and treatment may not be initiated for all of these patients, but close monitoring is essential. On the other hand, in some individuals, even when the eye pressure is below 21 mmHg, and even within the normal range, damage to the optic nerve may develop. This condition, known as normal tension glaucoma, is the clearest evidence that eye pressure alone is not a sufficient indicator. The eye doctor evaluates all of this data together to determine an individualized target pressure value for each patient. The goal during the treatment process is to reduce the pressure to a level that will stop any progression of damage in the optic nerve, and to maintain that level.

Methods such as drops, laser, or surgical procedures can be used to lower intraocular pressure. The initial method and treatment will be determined according to the type of glaucoma, its stage, the target pressure, and the patient’s condition. It is not necessarily required to use drops or to expect drops to be ineffective before considering laser in every patient. The prescribed drops should be used regularly and should not be discontinued without the advice of a physician.

In addition to medical treatment, changes in lifestyle can contribute to the control of glaucoma. Several studies have shown that regular and moderate aerobic exercise, such as walking, swimming, or cycling, can temporarily reduce intraocular pressure. However, it is necessary to avoid exercise in heavy lifting or in positions where the head is held downwards, as these movements can temporarily increase intraocular pressure. Obtaining sufficient and quality sleep, managing stress, and avoiding excessive caffeine intake can also be factors that help control glaucoma. Regarding water consumption, there is a point that should be considered: consuming a very large amount of liquid in a short period of time can cause a temporary increase in intraocular pressure, therefore, it is recommended to spread liquid intake throughout the day. In all cases, changes in lifestyle should not replace medical treatment recommended by a physician; these applications are supportive of the treatment.

Balanced nutrition is beneficial for overall health; however, it should not be assumed that a specific food will reduce eye pressure to a level that treats it, or reverse nerve damage caused by glaucoma. A dietary pattern including vegetables, fruits, and other food groups is evaluated in conjunction with an individual’s health status.

Herbal products and vitamin supplements do not replace prescribed drops, laser treatment or surgery. Tell the doctor about supplements because they may interact with medication. Glaucoma follow-up relies on monitoring target intraocular pressure, the optic nerve and visual field together.

Elevated intraocular pressure, if left untreated, can lead to serious and irreversible consequences over time. Persistent high pressure exerts constant pressure on the optic nerve, resulting in the gradual damage of nerve fibers. This damage typically begins with a narrowing of the peripheral visual field; a person may gradually begin to lose their vision to the sides, above, or below. This condition, also known as tunnel vision, can significantly impact daily life. This may manifest as an inability to perceive vehicles approaching from the sides while driving, collisions with obstacles while walking, and difficulty navigating stairs. As the process progresses, the visual field continues to narrow, and central vision also begins to be affected. Untreated glaucoma can ultimately lead to complete and permanent blindness. Damage to the optic nerve cannot be reversed using current medical practices; the lost visual field cannot be regained. Therefore, early diagnosis and treatment are of paramount importance in preserving existing vision.

The effects of leaving eye pressure untreated are not limited to vision function; it also significantly reduces a person’s quality of life. Vision loss diminishes the ability to perform independent movements, increases the risk of falls and accidents, and makes reading and daily activities more difficult. Progressive vision loss in one or both eyes can also negatively affect a person’s psychological state, potentially leading to depression and social isolation. Untreated acute angle closure glaucoma is an emergency situation that can lead to permanent vision loss within hours. Considering all these risks, it is of great importance that individuals with elevated eye pressure or a risk of glaucoma adhere to the treatment process and continue with regular checkups. The aim in treating eye pressure is not to completely eliminate the disease, but to preserve existing vision and stop its progression. This goal can only be achieved through early diagnosis, regular monitoring, and continuous treatment.
