Muscae Volitantes (Floater) - Treatments In Traditional Chinese medicine perspective

Muscae volitantes or Floater is defined as a condition of pathol moving black specks or threads seen before the eyes, as results of opaque fragments floating in the vitreous humour or a lens defect due to degeneration of the vitreous humour.  Floater as it suspends in the vitreous humour, it tends to drift  and follows the rapid motions of the eye as a result of damage of the eye that causes material to enter the vitreous humour.

The clinical manifestations are said to range from mild cases with black shadows floating up and down like flying flies (but no other change in vision) to severe cases, where the eyes seem to be covered by a membrane. There are three categories of causation listed: 
1.  Accumulation and steaming up of damp-heat and attack of turbid qi a. This corresponds to the disorder of the gallbladder described above.  b. A recommended formula is modified San ren Tang (Three Seed Decoction), which have a function to clear damp-heat. Ingredients includes b.1. Xing Ren (Apricot Seed or Kernel) b.2. Bai Dou Kou (Round Cardamom Fruit) b.3. Hou Po (Magnolia Bark) b.4. Ban Xia (Pinellia Rhizome) b.5. Yi Yi Ren (Seeds of Job's Tears) b.6. Tong Cao (Rice Paper Pith, Tetrapanax) b.7. Dan Zhu Ye (Lophatherum Stem and Leaves) b.8.Hua Shi (Talcum)
2. Stagnation of liver qi, resulting in blood stasis and extravasation of blood

3. Deficiency of kidney and liver, resulting in flaring up of deficiency fire
