“Normal-Tension” Glaucoma: Hidden Threat in Philippines

Normal-Tension Glaucoma: Hidden Threat in the Philippines


Glaucoma is often referred to as the \”silent thief of sight\” due to its stealthy nature. Among the various types of Glaucoma, Normal-Tension Glaucoma (NTG) is an even more elusive threat, affecting the Filipino population with little to no early warning signs. This article aims to shed light on this hidden danger, to inform and encourage Filipinos to prioritize their eye health and take necessary preventive measures.

What is Normal-Tension Glaucoma?

Normal-Tension Glaucoma is a form of primary open-angle Glaucoma, where the optic nerve gets damaged even though the eye pressure remains within a normal range. It differs from other types of Glaucoma in that the high pressure often associated with Glaucoma is absent. The underlying causes of NTG are not yet fully understood, but factors like reduced blood flow to the optic nerve may contribute to its development.

Prevalence and Risk Factors in the Philippines

Recent statistics have shown a steady increase in the number of Glaucoma cases in the Philippines. Among these, NTG remains a significant contributor to the overall cases. Risk factors like increasing age, a family history of Glaucoma, and high myopia (nearsightedness) may increase the likelihood of developing NTG. Certain lifestyle and environmental factors specific to the Philippines, such as a high prevalence of smoking and pollution, may also exacerbate the risks.

Symptoms and Early Detection

Normal-Tension Glaucoma is particularly dangerous due to its lack of noticeable symptoms. Signs such as tunnel vision, loss of peripheral vision, or blurry vision may only become apparent in the later stages of the disease, resulting in irreversible vision loss. This underscores the importance of early detection through regular eye examinations and consultations with eye care professionals. Comprehensive eye exams can help detect potential risk factors and enable timely intervention to prevent further deterioration.

Treatment and Management Options

Although there is no cure for Normal-Tension Glaucoma, proper treatment can help manage the condition effectively. The primary goal of treatment is to slow down or halt the progression of the disease by reducing eye pressure. This can be achieved through:

  1. Eye drops: The first line of treatment, these help lower the pressure in the eyes.
  2. Laser therapy: To improve fluid drainage in the eyes and subsequently alleviate pressure.
  3. Surgical procedures: An option for those who do not respond well to eye drops or laser therapy.

In the Philippines, several clinics and hospitals specialize in Glaucoma treatment, offering state-of-the-art facilities and expert guidance. Adopting a healthy lifestyle, avoiding smoking, and maintaining a balanced diet can also help manage the condition and prevent further damage.


Normal-Tension Glaucoma is a hidden threat in the Philippines, deserving of greater awareness and attention. By understanding the risks and symptoms of this silent menace, Filipinos can take the necessary steps towards proactive eye care and timely prevention. Do not take your eyesight for granted – make eye health a priority and seek regular check-ups for early detection and treatment.
