Question 54: What is the cause of blurred vision in pregnant women?
Answer: This is due to blood failing to nourish the eyes. During pregnancy, blood is primarily used to nourish the fetus and does not adequately nourish the Liver (Zang organ associated with vision). Consequently, Liver Qi becomes deficient and weak, leading to blurred vision. It is appropriate to administer Fuling Bulgan San (Poria Decoction for Nourishing the Liver), Xuxiao San (Deficiency-Dispelling Powder), or Jiaohong Wan (Red Pepper Pill).
Question 55: What is the cause of blurred vision after childbirth?
Answer: This results from excessive blood loss postpartum, causing both Ying (Nutritive Qi) and Wei (Defensive Qi) to become deficient. The Shen Guang (spiritual light/vision function) thereby becomes depleted, leading to blurred vision. It is appropriate to administer Juhua San (Chrysanthemum Powder), Renshen Jiaohong Wan (Ginseng and Red Pepper Pill), Danggui Huoxue Jian (Angelica Sinensis Blood-Invigorating Decoction), or Siwu Tang (Four Substances Decoction).
Question 56: What is the cause of redness and ulceration of both eyes in infants under one year of age?
Answer: This is caused by fetal toxins. Before birth, turbid pathogens condense between the eyelids of the eyes. After birth, if bathing and wiping are not thorough, residues remain inside the eyes. Combined with invasion by Wind pathogenic factors, this leads to redness and ulceration of both eyes. It is appropriate to administer Huanglian San (Coptis Powder) or Huapi Nanxing Tang (Birch Bark and Acorus Decoction).
Question 57: What is the cause of chickenpox/rash invading the eyes in children?
