Night Blindnessaccording to TCM

What is Night Blindness?

Night blindness, or nyctalopia, refers to difficulty in seeing in low-light conditions. It is not a disease but rather a symptom of an underlying condition affecting the retina, where rod cells that assist in low-light vision are compromised. This visual impairment can lead to challenges in navigating or driving at dusk or dawn and can significantly affect the quality of life.

How does TCM view Night Blindness?

In Traditional Chinese Medicine (TCM), a 'pattern' is a comprehensive analysis of a person's health issues, encompassing not just the symptoms but also the underlying disharmony causing them. Recognizing a pattern is crucial because it guides the practitioner to a tailored treatment strategy.

For night blindness, identifying whether the pattern stems from a Blood Deficiency or a Yin Deficiency, for instance, is vital. This diagnosis informs the choice of acupuncture points, herbal formulas, and lifestyle adjustments. It's this nuanced approach that allows TCM to address not just the symptom of night blindness, but to nurture the body's overall well-being, aiming for long-term improvement and prevention.

Root Causes of Night Blindness in TCM

TCM discerns several patterns that might lead to night blindness. A prevalent cause is Blood Deficiency, particularly of the Liver and Heart, which can manifest symptoms such as pale complexion and dizziness, alongside vision issues.

Another common pattern is Liver Yin Deficiency, where a lack of vital Body Fluids affects the eyes, causing symptoms like dry eyes and poor night vision. These patterns reflect a deeper disharmony within the body that TCM seeks to address through a holistic approach to restore equilibrium.

Detailed description of the cause

Blood Deficiency

Blood Deficiency in TCM is like when your body's tank runs low on the vital energy that blood provides. It's not exactly the same as anemia in modern medicine, which is about having too few red blood cells. Instead, Blood Deficiency in TCM is about your body not having enough of the life-giving qualities that blood brings, like nourishment and moisture. This can make you feel tired, look pale, and even feel dizzy or have blurry vision. It's like a garden not getting enough water to stay lush and vibrant. TCM sees this as an imbalance where the body isn't being nourished as it should be, impacting overall health and well-being.... see more

Yin Deficiency

Yin deficiency in TCM is a pattern of disharmony characterized by a depletion of the body's Yin energy, which represents the cooling, moistening, and nurturing aspects of our physiology. This condition often arises from factors like chronic stress, overwork, insufficient rest, or prolonged illness. Symptoms of Yin deficiency can include a sensation of heat, especially in the afternoon or evening, night sweats, insomnia, a dry mouth or throat, and a red tongue with little coating. There might also be a general feeling of restlessness or irritability. Since Yin is essential for balancing the body's active and warm Yang energy, its deficiency leads to a relative excess of Yang, manifesting as heat or dryness symptoms.... see more

Blood Stasis

Blood Stasis in TCM is a concept where the blood flow in the body is not as smooth or efficient as it should be. Imagine a river that's supposed to flow freely, but instead, it's getting blocked or moving too slowly in some parts. This can lead to various health issues, like pain that feels sharp or stabbing, dark bruises, and a complexion that looks purplish. TCM believes that good health relies on the smooth and vibrant flow of Qi and blood throughout the body, so when blood gets stuck, it's like a traffic jam in your body, leading to discomfort or health problems.... see more

Liver

In TCM the Liver is viewed as the organ responsible for the smooth flow of Qi, Blood, and emotions throughout the body. It plays a key role in regulating mood, storing blood, supporting digestion, and ensuring the health of tendons and eyes. When the Liver malfunctions or is imbalanced in TCM, it can lead to a range of issues such as irritability, mood swings, menstrual irregularities, eye problems, and muscular stiffness or pain. A malfunctioning Liver in TCM reflects not only physical disturbances but also emotional and mental disharmony, emphasizing the holistic approach of TCM in addressing health and wellness.... see more

Heart

In TCM the Heart is considered the "emperor" of all organs, primarily responsible for governing Blood and housing the mind, known as "Shen." It plays a crucial role in maintaining mental-emotional equilibrium and controlling the circulation of Qi and blood throughout the body. When the Heart is imbalanced or malfunctions in TCM, it can lead to a range of issues like heart palpitations, insomnia, dream-disturbed sleep, anxiety, and a flushed complexion. Emotional disturbances such as excessive joy or lack of joy are also seen as signs of Heart disharmony. These symptoms reflect not just physical heart conditions but also the state of one's Shen, indicating the interconnectedness of physical and emotional well-being in TCM.... see more

Spleen

In TCM the Spleen plays a vital role in digestion and transformation, converting food into energy and nutrients, and overseeing the distribution of Qi and Blood. It's also crucial in maintaining the health of muscles and limbs and ensuring the blood remains within the vessels. When the Spleen malfunctions in TCM, it can lead to a variety of issues such as digestive disorders, fatigue, weak muscles, bloating, and a feeling of heaviness. It can also cause a pale complexion, poor appetite, and a tendency to bruise easily. Emotionally, a Spleen imbalance is often associated with excessive worry or overthinking, reflecting its role in the interplay between physical and mental health.... see more

Acupoints for Night Blindness

TCM also employs acupoint therapy to address night blindness. Points along the Gall Bladder Channel like Fengchi GB-20, Guangming GB-37, and Tongziliao GB-1 are chosen for their proximity to the sensory orifices and their reputed ability to benefit the eyes by subduing Liver Yang and clearing Wind.

Additionally, Bladder Channel points such as Jingming BL-1 and Shenshu BL-23 may be utilized to nourish and strengthen the Kidneys, which in TCM are believed to provide essential support to the eyes.
