Structures of the eyes

Itchy eyes are a typical feature of allergic conjunctivitis. Individuals often accompany with other eye symptoms like redness, tearing, soreness, burning or painful sensations, excess discharges, sensitivity to light and swollen eyelids. The intensity can vary from person to person. When itchy eyes appear at certain period of year such as in spring and fall seasons, seasonal allergic conjunctivitis is diagnosed, and the allergens are likely to be pollen from grasses, weeds, and trees. Perennial allergic conjunctivitis is referred to itchy eyes that happen all year around, which usually indicated a constant exposure to household allergens such as dust mites, mold or pet dander. Some individuals may also be sensitive to contact lens solution, makeup, smoke, or eye cream. It is not uncommon for individuals to have other allergic symptoms, such as nasal congestion, runny nose and sneezing.

The eyes rely on essence of the organs for nourishment, when the organs are under-functioning and fail to nourish the eyes, normal eyesight will be affected, and it may even result in eye diseases. During an eye consultation, TCM physicians will check different parts of the eyes, and correlate them with particular organs, which is a unique eye diagnostic method.

Based on these relationships between the eyes and organs, physicians can identify what organ has involved in an eye problem. Then they will combine other diagnostic routine to get a comprehensive evaluation for patients and guide the clinical treatment.

Syndrome differentiation treatment for itchy eyes

In TCM understanding, allergic conjunctivitis is regarded as a "qi wheel problem" of the eyes that may develop in the following ways:
Protective qi of lungs is weak that leads to external wind and heat pathogens attacking the eyes.
Stomach and spleen dysfunctions that lead to damp-heat accumulation internally. Meanwhile external wind pathogens take advantage to attack the eyes and trigger the itchy symptom.
Liver blood insufficiency that generates wind pathogens internally to attack the eyes.

Generally, TCM believes that development of allergic conjunctivitis is mainly determined by constitutional factor, external or environmental factors are merely the triggers.
