Fire gān

A red granule, like a pomegranate seed in shape, bulging forward from deep within the white of the eye, and growing gradually larger. Fire gān is associated with redness, pain, tearing, aversion to light, and unclear vision. In some cases, it can affect the pupil, leading to loss of sight. In the latter stages, pain and redness abate to leave purple-blue or blue-gray patches.

Medicinal therapy: Clear heat and resolve toxin; clear the blood and disperse binds. Use formulas such as Heart-Washing Powder (洗心散 xǐ xīn sǎn). Formulas containing biles may be applied topically. See gan.
