Eye spot

Introduction Normal people's white eyeballs have no other colors, generally white and radiant. If the internal organs are ill, a color change occurs in the white eye. On the white eyeballs of young children, there are often blue, gray, or dark gray spots, single or scattered, the realm is clear, the spots around are normal, and more confirmed to have tsutsugamushi. Need to pay attention to the prevention of eye spots: strengthen publicity and education, popularize health knowledge, pay attention to food hygiene and personal hygiene, wash hands before and after meals, do not eat unwashed vegetables and fruits, do not drink raw water, prevent food Insect eggs are added to reduce the chance of infection.

Cause

The cause of eyeball spots may be caused by ascariasis. See blue, gray, or dark gray spots, single or scattered multiple, clear boundaries, normal around the spots. If you find such spots, go to the hospital to check if there are any mites in the stool. Necrotic liver tissue and eggs in the abscess can still flow into the hepatic vein to cause hepatic vein inflammation and thrombosis, and even enter the lung through the right heart, causing pulmonary infarction and suppuration symptoms. Liver aphid granuloma is a female mites that invade the liver and cause a large number of eggs. In the early stage, it is an eosinophilic abscess and forms a granuloma later. If the internal organs are ill, a color change occurs in the white eye.

Tear lactate dehydrogenase:

LDH (EC 1.1.1.27) and MDH (EC 1.1.1.37) in tears are mainly derived from the corneal epithelium of the eye. Their concentration in tears is about 20 times that of the enzyme in serum. The tear LDH mainly contains the M subunit, with the highest content of LDH5 and LDH4. The MDH isoenzyme of tears can be separated from MDHs and MDHm by electrophoresis of vinegar membrane. The tears of healthy people are mainly MDHs.

Tears lactoferrin:

LF is named for its ability to be first found in cow's milk and has a strong ability to bind high iron. It is a glycoprotein with an isoelectric point of about pH 7.8, a molecular weight of 75 to 86 kD, and a protein moiety consisting of a polypeptide chain. LF can inhibit the growth of a variety of bacteria, and can also promote the antibacterial effect of lysozyme, synergistic with SIgA, the antibacterial activity is stronger than when both exist alone. LF is present in various body fluids and secretions such as milk, tears, saliva, semen, urine, pancreatic juice, bile and respiratory secretions. LF in various body fluids of the human body has the same immunological properties.

Differential diagnosis

Symptoms of eyeball spots that are confusing:

Normal people's white eyeballs have no other colors, generally white and radiant. If the internal organs are ill, a color change occurs in the white eye. On the white eyeballs of young children, there are often blue, gray, or dark gray spots, single or scattered, the realm is clear, the spots around are normal, and more confirmed to have tsutsugamushi.

Differential diagnosis of eye spots:

1. Black spots on the white of the eye: It may be the passage of the blood vessels in and out of the eye wall. Since the blood vessel is perpendicular to the wall of the eyeball, we see its cross section, so it is like a black spot (the blood vessels are very thin). This is a normal physiological phenomenon.

2, the yellow spots on the conjunctiva: generally are pigmentation fat droplets and other pigmentation.

3, corneal dry spots: refers to the corneal epithelium accumulation of corneal dry spots, mainly seen in vitamin A deficiency.

4, conjunctival dry spots: Bi-spotted spots, also known as conjunctival dry spots, vitamin A deficiency. Children lack the most important clinical signs of vitamin A. The patient is close to the cornea and the outside of the conjunctiva due to dryness and wrinkles, and the keratinized epithelium accumulates, forming white spots of varying sizes resembling foam.

See blue, gray, or dark gray spots, single or scattered multiple, clear boundaries, normal around the spots. If you find such spots, go to the hospital to check if there are any mites in the stool.
