double eyelashes
Introduction
Double line eyelash introduction The double-lined eyelashes are the other side of the root of the lashes, which is equivalent to the growth of another row of eyelashes, also called the secondary eyelashes. For congenital malformation dysplasia, it may be dominant inheritance. There are 3-5 minor eyelashes and more than 20. It is common in both eyes and squats, but it also occurs in the eyelashes or monocular eyes. Diseases are caused by abnormal development of congenital eyelashes and may be dominantly inherited. Dominant inheritance is controlled by dominant genes. On the homologous chromosome, two homologous dominant genes are paired, or the dominant and recessive gene alleles are present. This type of inheritance is called dominant inheritance. If the secondary conjunctiva is small and soft, and there are not many corneas, and the symptoms are not serious, often apply eye ointment or soft corneal contact lens to protect the cornea. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: trichiasis
Cause
Double line of cause
Diseases are caused by abnormal development of congenital eyelashes and may be dominantly inherited. Dominant inheritance is controlled by dominant genes. On the homologous chromosome, two homologous dominant genes are paired, or the dominant and recessive gene alleles are present. This type of inheritance is called dominant inheritance.
The so-called dominant genetic disease refers to the fact that fathers and/or mothers carry certain genes and develop clinical manifestations, and their genes are passed on to the next generation. The autosomal hereditary polycystic kidney disease is the case. The upper generation carries the cyst gene. And the clinical changes of polycystic kidney disease occur, and polycystic kidney changes occur after the offspring are inherited. Dominant inheritance is the genetic pattern exhibited by dominant genes.
Prevention
Double line eyelash prevention
1. Avoid infection.
2. Take care to protect your eyes.
Complication
Double line eyelash complications Complications
If the secondary eyelashes are soft, the stimulation of the cornea is not heavy. If the secondary eyelashes are thick and hard, it often causes corneal irritation, and the crease examination can find the fluorescein staining in the lower part of the cornea.
Symptom

Generally, the auxiliary eyelashes are short and soft, and have less pigmentation, but they are also the same as normal eyelashes. Arrange the rules, erect or tilt backwards. If the secondary eyelashes are soft, the stimulation of the cornea is not heavy. If the secondary eyelashes are thick and hard, it often causes corneal irritation, and the crease examination can find the fluorescein staining in the lower part of the cornea.
Examine
Double eyelash examination
A slit examination revealed fluorescein staining in the lower part of the cornea. The slit lamp microscope consists of an illumination system and a binocular microscope. It not only makes the superficial lesions clearly visible, but also adjusts the focus and source width to create an "optical section", so that the lesions of the deep tissue can also be clearly seen.
Diagnosis

Diagnosis can be based on the cause, symptoms and related tests.
