Four diet prescriptions for night blindness caused by vitamin A deficiency

Abstract: night blindness is an eye disease caused by vitamin A deficiency. Patients have poor vision or can’t see at all in dark environment or at night. There are cone cells and rod cells in the retina of normal people. Cone cells are responsible for sensing strong light and distinguishing color, while rod cells can sense weak light but have no ability to distinguish color., If you can’t see it in the dark for five minutes, you may be suffering from night blindness and need to go to the hospital for examination in time. Vitamin A affects people’s visual ability at night. If there are symptoms of night blindness, taking a large amount of vitamin A can be improved within a few hours, but taking a large amount of vitamin A must be approved by the doctor., Night blindness is an eye disease caused by vitamin A deficiency. Children with some kind of congenital night blindness can see things in a well lit environment, but they can hardly see anything in the dark. Without exception, these children are extremely afraid of the dark. Remind parents that if children are afraid of the dark, don’t take it for granted that it’s just because they are timid and should consult a doctor., Night blindness is an eye disease caused by lack of vitamin A. patients have poor vision or can’t see at all in dark environment or at night. There are cone cells and rod cells in the retina of normal people. Cone cells are responsible for sensing strong light and distinguishing color, while rod cells can sense weak light but have no ability to distinguish color. Rod cells contain rhodopsin, which will be destroyed and faded by light in bright places. In dark places, it can be recovered by depending on opsin and vitamin A in blood., If the human body is deficient in vitamin A, the resynthesis of rhodopsin is impaired and dark adaptation is reduced, night blindness will appear., There are three symptoms of night blindness: 1. Iron filings night blindness. In production and labor, when iron filings pop into the eye, it will immediately produce serious irritation symptoms; If the iron filings are not completely removed, chemical changes will slowly occur in the eye to produce iron oxide, which will affect the function of rod cells in the retina and cause night blindness. It is characterized by a history of foreign body popping into the eye; Most of them are unilateral. Due to the compensatory effect of the healthy side, it is often difficult to find their night blindness, which is often found when the healthy side’s eyes are ill or during physical examination. This kind of night blindness cannot be treated with va. the only way is to remove the iron filings in the eyes, which are the symptoms of night blindness., If you can’t see

in the dark for five minutes, you may be suffering from night blindness and need to go to the hospital for examination in time. Vitamin A affects people’s night vision ability. If there are symptoms of night blindness, taking a large amount of vitamin A can be improved within a few hours, but taking a large amount of vitamin A must be approved by the doctor.

children with some kind of congenital night blindness. Although these children can see in a well lit environment, they can hardly see anything in the dark. These children are extremely afraid of the dark without exception. Remind parents that if children are afraid of the dark, don’t take it for granted that it’s just because they are timid and should consult a doctor.

if the human body lacks vitamin A, the resynthesis of rhodopsin is impaired, and the dark adaptation is reduced, night blindness will appear.

three symptoms of night blindness

1. Iron filings night blindness

in production and labor, when iron filings pop into the eye, it will immediately produce serious irritation symptoms; If the iron filings are not completely removed, chemical changes will slowly occur in the eye to produce iron oxide, which will affect the function of rod cells in the retina and cause night blindness. It is characterized by a history of foreign body popping into the eye; Most of them are unilateral. Due to the compensatory effect of the healthy side, it is often difficult to find their night blindness, which is often found when the healthy side’s eyes are ill or during physical examination. This kind of night blindness cannot be treated with va. the only way is to remove the iron filings in the eyes, which are the symptoms of night blindness.

2. Extensive old choroiditis

choroid is a kind of tissue close to the retina, which is covered with rich blood vessels to supply the nutrition of the retina. When the choroid produces extensive old inflammation, it can shrink and affect the blood supply of the retina. It can not only denature and destroy the rod cells on the retina and cause night blindness, but also reduce vision due to the blood supply disorder of pyramidal cells, and the visual function of patients is also poor during the day. These are the symptoms of night blindness.

3. Retinitis pigmentosa

the disease is an eye disease with genetic factors. It usually involves the rod cells on the retina first, resulting in night blindness. The degree of night blindness is gradual. With the development of the lesion, it can affect pyramidal cells, resulting in a decline in daytime vision. Therefore, patients with retinitis pigmentosa often have night blindness first. The lesions are bilateral and easy to be found. Then, the field of vision can be reduced, and even a “tubular field of vision” can be generated, resulting in blindness. Diet therapy below
