গ্লুকোমা is a collective term for a group of eye diseases that can lead to progressive damage of the optic nerve and cause irreversible blindness if left untreated. গ্লুকোমা can slowly and steadily compromise vision without showing any warning signs.
Medical intervention is needed to lower the intraocular pressure to manage গ্লুকোমা. However, integrating certain lifestyle changes may help mitigate its impact.

What Is Low-Tension Glaucoma?
Low-tension গ্লুকোমা, also known as normal tension গ্লুকোমা, is a characteristic glaucomatous optic neuropathy with intraocular pressure in the range of normal limits. It is a common eye condition and can lead to bilateral blindness.
The optic nerve transmits visual signals that allow light to pass. Unfortunately, in most cases, high intraocular pressure triggers damage. The exact cause is unknown, but experts believe that vascular dysregulation and genetic predisposition might play a role.
Lowering intraocular pressure is standard care for low-tension গ্লুকোমা.
Causes of Low-Tension Glaucoma
The exact cause of low-tension গ্লুকোমা or normal tension গ্লুকোমা remains unclear. Unlike other types of গ্লুকোমা, it occurs without high intraocular pressure. However, several factors can contribute to optic nerve damage, including:
- Poor Blood Circulation: A reduced blood supply in the body may deprive the optic nerve of oxygen and nutrients, leading to gradual deterioration.
- Vascular Disorders: Conditions such as migraine, Raynaud’s disease, obstructive sleep apnoea (OSA), along with low blood pressure, can affect the blood supply to the optical nerve.
- Structural Optic Nerve Weakness: Some individuals are born with a fragile optic nerve, making them more susceptible to damage, even with normal intraocular pressure.
- জেনেটিক্স: Family history plays a major role in increasing the likelihood of developing low-tension গ্লুকোমা.
Signs and Symptoms of Low-Tension Glaucoma
In its early stage, low-tension গ্লুকোমা may not show any signs, and in some cases, the symptoms may not appear until the condition causes irreversible blindness.
Some of the low-tension glaucoma signs and symptoms to look out for are:
- চোখের ব্যথা বা চাপ
- মাথাব্যথা
- আরক্ত চোখ
- ডবল দৃষ্টি
- ঝাপসা দৃষ্টি
- Gradually developing low vision
In a particular type of গ্লুকোমা, angle closure গ্লুকোমা, symptoms may appear suddenly and require immediate medical attention. These symptoms include:
- Blood gathering in front of the iris
- Bulging eyeballs
- বমি বমি ভাব এবং বমি
- Rainbow colored halos around light
- হঠাৎ দৃষ্টিশক্তি হ্রাস
Treatment Options for Low-Tension Glaucoma
The damage caused by low-tension গ্লুকোমা cannot be reversed, but treatment and regular check-ups can slow down the progression and prevent vision loss, especially if this is caught in the early stage.
Low-tension glaucoma treatment is based on lowering intraocular pressure. Treatment options include medications, laser therapy and surgical treatments.
ওষুধ
The remedy frequently starts with eye drops. Drugs to reduce eye pressure include prostaglandin analogues, beta-blockers, alpha agonists, and carbonic anhydrase inhibitors.
In case the pressure is already normal, it can be reduced further to help prevent further damage to the optic nerve.
লেজার থেরাপি
Selective laser trabeculoplasty (SLT) may be offered if medications do not sufficiently lower pressure or cause side effects. SLT improves the drainage of aqueous fluid from the eye, helping to reduce IOP without the need for incisions.
Laser treatment can be repeated if necessary and is considered safe, although its effectiveness may vary among individuals with normal tension গ্লুকোমা.
অস্ত্রোপচার চিকিত্সা
Surgery is usually considered when medications and laser therapy fail to control the disease. Trabeculectomy and গ্লুকোমা drainage devices are common surgical options to lower IOP further.
ন্যূনতমরূপে আক্রমণকারী গ্লুকোমা surgeries (MIGS) may be appropriate in selected cases. However, the choice of procedure depends on the severity of the disease and patient-specific factors.
Lifestyle Changes to Manage Low-Tension Glaucoma
Making some significant lifestyle changes plays a supportive role in managing low-tension গ্লুকোমা. However, they should not be considered a replacement for medical therapies.
Diet and Nutrition
It is possible to prevent damage to the optic nerve caused by low-tension গ্লুকোমা by maintaining a balanced diet. The diet should include a balanced mix of antioxidants, vitamin A, C, and E, as well as omega-3 fatty acids.
Eye function can be supported with vegetables in shades of green, oily fish and nuts. It is also recommended to avoid excessive caffeine, which can temporarily increase eye pressure, and to limit salt intake to help maintain normal blood pressure levels.
Eye Care and Regular Checkups
Even when you do not have any symptoms, frequent monitoring by reputable eye specialists, such as Dr Agarwal’s, is essential. Eye pressure, visual field, and optic nerve imaging must be monitored to detect progression early.
Using prescribed medications regularly, avoiding over-the-counter eye drops without consulting a doctor, and wearing sunglasses to protect the eyes against the impact of UV rays can contribute to the long-term preservation of the eyes.
Stress Management and Physical Activity
Poor sleep patterns and chronic stress can influence the ocular blood flow. Vascular health can be maintained by including stress reduction measures, such as yoga, meditation, and breathing exercises.
Light aerobic activity, such as walking or swimming, can be performed to enhance blood circulation and may also help the eye nerve. Activities that use the inverted position (such as headstands) or any that involve heavy lifting should, however, be performed with caution.
When to See a Doctor for Low-Tension Glaucoma
You should see a specialist for low-tension গ্লুকোমা if you:
- Have a family history of গ্লুকোমা
- Experience vision changes, even if minor
- Have been diagnosed with sleep apnea, autoimmune conditions, or vascular disorders
- Are over 40 years old and haven’t had a recent comprehensive eye exam
Early detection is important, especially in low-tension গ্লুকোমা, where typical signs like high eye pressure may not be present.
উপসংহার
Managing low-tension গ্লুকোমা requires a proactive approach along with regular monitoring, personalized medical treatment and lifestyle changes. With early detection and adherence to prescribed medical treatment plans, many patients with normal tension গ্লুকোমা can preserve vision and lead a healthy life.
Making certain lifestyle changes plays a crucial role in the long-term management of low-tension গ্লুকোমা. These changes include adopting a healthy diet, regular eye care, and managing health conditions, especially diabetes.
