2. night blindness vitamin Review – VITAMIN HISTORY, THE EARLY YEARS

night blindness vitamin REVIEW – IMAGE SOURCE AMAZON

Casimer Funk 101 years ago first used the term ‘vitamine’ in 1912. What were later to be known as vitamin-deficiency diseases, such as scurvy, beriberi, night blindness, xerophthalmia and rickets, had plagued the world at least since the existence of written records. Records of medical science from antiquity attesting to human association of certain foods(e.g. liver) with either the cause or prevention of diseases are considered the nebulious beginnings of the concept of these essential nutrients. The concept of a vitamin or ‘accessory growth factor’ was developed in the early part of the 20th Century and for almost five decades there was an exciting era of isolation, identification and synthesis of the vitamins. The present book contains 10 chapters and methodically traces each vitamin from an unidentified factor to its discovery and synthesis. In relation to history of nutrition, vitamins are by far the most interesting class of nutrients. Following the clues of the existence of each vitamin is similar to a good mystery story. The early beginnings of the vitamin theory relate to reports that animals did not survive on diets of only carbohydrares, fats, protein and salts. Beriberi was the earliest documented deficiency disorder (2697 B.C.). High incidence of beriberi in Asian countries was due to over milling rice( polished rice). The subsequent research in this disease led to the discovery of vitamins and helped to establish some of the principal features of deficiencies in general. Vitamin A deficiency results the in two eye diseases of night blindness and xeropthalmia. According to some of the oldest records, liver cured these diseases. Rickets, the devastating bone disease of young children is a vitamin D deficiency. The vitamin is referred to as the ‘sunshine vitamin’ as it can be synthesized in the body. Rickets was common in northern cities and was more rampant in industrial cities as industrial pollution prevented children from sunlight exposure. Pellagra, a niacin deficiency, is a devastating disease that brought pain, suffering and death and resulted when corn was the main food source. Symptoms of the disease were referred to as the 4 D’s, dermatitus, diarrhea, dementia and death. Scurvy which had been feared since ancient times resulted from diets devoid of vitamin C-rich foods of fruits and vegetables. Scurvy was the vitamin deficiency disease that caused the most death and suffering in recorded history. A fatal anemia, pernicious anemia, was a vitamin B-12 deficiency. The disease resulted by only consuming plant foods, or lack of a factor produced by the stomach needed for absorption of the vitamin.

The book contains pictures of very serious consequences and magnitude of vitamin deficiency diseases. Likewise, the book contains levity by illustrating humorous situations on causes and cures of these diseases. The purpose of the present publication is to present an in depth review of the early history of vitamins to illustrate the devastation of these diseases and also provide some levity.

Author Bio: The author of the book, Dr. Lee McDowell is a nutritional professor at the University of Florida. In nutrition research he has published over 1500 scientific articles and has written 7 books. Five different nutrition courses have been taught, with a graduate vitamin nutrition course offered over 25 years. During this time period he wrote two editions of a vitamins textbook for his graduate class and for courses at other universities. Dr McDowell is a ‘Fellow’ of two International Societies and has won many awards in teaching and research. From one society he won the highest award available for research (Morrison Award). Internationally Dr. McDowell is well known having made 271 different country visits since 1971. He has given over 500 major talks in 42 different countries. ‘Early Vitamin History”, presented in a humorous way, is his most favorite topic.

3. night blindness vitamin Review – A Simple Guide to Night Blindness and Causative Diseases (A Simple Guide to Medical Conditions)

night blindness vitamin REVIEW – IMAGE SOURCE AMAZON

Night Blindness is defective vision at night or in conditions of lowered illumination.

The rod cells in the retina are responsible for our ability to see at night.

This is why any loss of peripheral vision such as in glaucoma often results in night blindness.
People suffering from night blindness not only see poorly at night.
They also require some time for their eyes to adjust from brightly lit areas to dim ones.

What are the causes of Night Blindness?

The main causes of Night Blindness are classified into 2:

A. Congenital Night Blindness:

This is a simple congenital defect of:

1. Dominant trait

2. Recessive trait

3. Recessive sex linked trait

B. Acquired Night Blindness:

This pathological state occurs when the rod function (which recognizes the light at night) of the retina cells are reduced:

1. Vitamin A deficiency
– Prolonged deficiency can affect marked degenerative changes in the rods, then cones and subsequently in the neuronal layers of the retina

Causes of Vitamin A deficiency are:
a. Inadequate dietary intake

b. Impaired absorption in celiac disease, tropical sprue or liver cirrhosis

2. Retinitis pigmentosa
– A degenerative disease of the retina affecting the cones and rods starting in the equatorial region and then spreading to the macular region

3. Cataracts
– A degenerative opacity of the lens which affects vision in day and night

4. Rare mucopolysaccharidase deficiencies
– group of lysosomal storage disorders due to defective metabolism of glycosaminoglycans, causing their accumulation and excretion and affecting the bony skeleton, joints, liver, spleen, eye, ear, skin, teeth, and the cardiovascular, respiratory, and central nervous systems.

5. Neuronal ceroid lipofuscinosis (NCL)
– Part of the group of neurodegenerative lysosomal storage disorders as above

6. Refsum disease:
– present with neurologic damage, cerebellar degeneration, and peripheral neuropathy.
Often have eye problems such as cataracts and poor night vision

7. Choroideremia:
Progressive atrophy of the choroid -very rare

8. Abetalipoproteinuria
Diffuse Night Blindness is inflammation in all areas of the uvea.

Night Blindness affects both eyes and is more common in the elderly:

What are the symptoms of Night Blindness?

Symptoms are:

1. Inability to see well at dusk or in dim light

2. Worse after long phases in bright sunlight

How is the diagnosis of Night Blindness made?

Diagnosis:

1. History, physical examination and family history eliminates the rarer causes of night blindness.

2. Measurement of Vitamin A or carotene levels

3. An early clinical sign of Vitamin A deficiency is conjunctival prexerosis associated with triangular areas of keratinized epithelium at the temporal limbus.

These are called Bitot’s spots.

4. Slit lamp examination of the retina

5. ElectroRetinoGraphy (ERG) of the eyes

What is the treatment of Night Blindness?

Treatment:

1. Most genetic causes of night blindness and retinitis pigmentosa cannot be cured

2. Vitamin A deficiency:

a. High doses of Vitamin A of 50,000 to 100,000 units per day up to 14 days.

Longer treatment may cause Vitamin A toxicity and damage the liver.

b. Maintenance dose of 2500 units of Vitamin A (or 750mg) is recommended daily.

What is the prognosis of Night Blindness?

Prognosis:
Depends on the cause – There is no cure for genetic causes

Poor when due to secondary causes such as glaucoma

Excellent in early treatment of Vitamin A deficiency

What are the preventive measures for Night Blindness?

Prevention:
1. Knowledge of family history

Genetic counseling may prevent genetic causes of night blindness

2. Avoid prolonged bright lights

3. Take natural forms of Vitamin A such as carotene in carrots, tomatoes, papaya and other vegetables and natural vitamin A in fish liver oils, liver and meat.

4. night blindness vitamin Review – A Simple Guide To Night Blindness, (Nyctanopia) Diagnosis, Treatment And Related Conditions (A Simple Guide to Medical Conditions)

night blindness vitamin REVIEW – IMAGE SOURCE AMAZON

Night Blindness (nyctalopia) is the medical symptom of defective vision at night or in situations of lowered lighting.
Night blindness or Nyctalopia (from Greek – ‘night’
‘blind, not seeing’, and ‘eye’) is a medical disorder indicating difficulty or impossibility to see in relatively low light.
Night blindness is the failure to see well at night or in poor light.
It is not a disease in itself, but rather a symptom of an underlying problem, normally a retina problem.
While the term “night blindness” suggests that the patient cannot see at night, this is not the case.
The patient may just have more difficulty seeing or driving in darkness.
It is frequent for patients who are myopic to have some trouble with night vision, but this is not due to retinal disease, but rather to optical disorders.

There are two forms of photoreceptors, rods and cones.
The rod cells in the retina are accountable for the ability to see at night.
The outer area of the retina is composed of more rods than cones, loss of peripheral vision often leads to night blindness.
This is why any loss of peripheral vision such as in glaucoma often leads to night blindness.
Rods have a receptor-protein called rhodopsin.
The body makes rhodopsin from vitamin A, which is why a deficiency in vitamin A produces poor night vision.
People affected by night blindness not only see poorly at night.
They also need some time for their eyes to adapt from brightly lit areas to dim ones.
Night blindness may produce difficulty with driving at night.
People with night blindness often have problem seeing stars on a clear night or passing through a dark room, such as a movie theater.
These troubles are often worse just after a person has been in a brightly lit environment.
Retinitis pigmentosa is the most frequent cause of night blindness
This is a degenerative disease of the retina involving the cones and rods.
Cataract is a degenerative opacity of the lens which affects vision in day and night.

Symptoms are:

1. Failure to see well at dusk or in dim light
2. Worsen after long durations in bright sunlight

Diagnosis of Night Blindness is made:
1. Slit lamp examination of the retina
2. ElectroRetinoGraphy (ERG) of the eyes
3. Measurement of Vitamin A or carotene levels
4. Bitot’s spots

Treatment for Night Blindness are:
1. Most genetic causes for night blindness and retinitis pigmentosa cannot be cured
2. Vitamin A deficiency:
a. High doses of Vitamin A of 50,000 to 100,000 units per day up to 14 days.
b. Maintenance dose of 2500 units of Vitamin A (or 750mg) is advised daily.
3. New prescription for the spectacles
4. Changing glaucoma medications,
5. Surgery may be required in cases of cataracts
Night blindness induced by nearsightedness, cataracts, or vitamin A deficiency is treatable.
Corrective lenses, such as eyeglasses or contacts, can enhance nearsighted vision both during the day and at night
Vitamin A can effectively treat night blindness in persons who have a deficiency of this nutrient.
Vitamin A may prevent night blindness and slow the progression of eye conditions, such as macular degeneration, which cause night blindness.
Wearing sunglasses during the day can prevent eye damage.
Natural forms of Vitamin A such as carotene in carrots, tomatoes, papaya and other vegetables and natural vitamin A in fish liver oils, liver and meat should be taken.
The diabetic patient properly monitors the blood sugar levels and eats a balanced diet to make night blindness less likely
Prolonged bright lights should be avoided.
