What is the suspected diagnosis based solely on color observation in the corners of the eyes?

The suspected diagnosis of Heart Fire is associated with the observation of color changes in the corners of the eyes, typically appearing red or inflamed. In Traditional Chinese Medicine (TCM), the color red is often indicative of heat conditions. The Heart is linked to the blood and is thought to be influenced by emotional states. When there is an excess of heat, particularly associated with the Heart, it can manifest as redness in the areas around the eyes.

The corners of the eyes are significant in TCM diagnostics, as they are considered to reflect the health of the organs, including the Heart. If there is a suspected Heart Fire, one might also anticipate additional signs such as irritability, thirst, and a red tongue with a yellow coating, which further supports this diagnosis.

In the context of the other options, while conditions like Lung Wind Heat and others could present with different symptoms and colors, the specific association of redness in the corners of the eyes aligns most closely with the characteristics of Heart Fire. Understanding these connections is crucial in TCM diagnostics, as it assists practitioners in forming a holistic view of the patient's condition.
