Xerophtalmia is the name for a group of symptoms due to vitamin A deficiency (VAD). It includes night blindness, Bitot’s spots, corneal ulceration, and eventually keratomalacia which leads to blindness.
The primary treatment is oral or injection vitamin A. The dosage is based on age and general health status. The doctor also asks the patient to eat yellow-coloured fruits and vegetables with ample beta-carotene as well as green leafy vegetables, meat and dairy.
Symptoms
Xerophthalmia (zeer-of-THAL-mă-uh) is the general term for a group of eye conditions caused by lack of vitamin A, which helps your eyes see well. Your body can’t produce vitamin A, so you need to get it through the foods you eat. Xerophthalmia can lead to blindness, especially in children. It’s the leading cause of blindness worldwide for people under the age of 5 years.
Symptoms include a dull or gritty feeling in the eyes, blurred vision, and itching. If left untreated, xerophthalmia can worsen to the point of causing pain or periods of temporary blindness. It can also damage the cornea, a clear outer layer of the eye that covers the front part of your eyeball. The damage is caused when your eye doesn’t produce enough tears or produces tears with abnormal levels of water, oil, and mucus.

The condition usually develops in young children who don’t have enough of a healthy diet or who are exposed to dry air or sunlight. But it can affect people of any age. It’s more common in poor countries and among children who have a disease or condition that reduces their tear production, such as AIDS, cirrhosis of the liver, or Sjogren’s syndrome (an immune system disorder).
If you think you have xerophthalmia, talk to your doctor. He or she will do a physical exam and ask questions about your symptoms and your diet. You may need a blood test to measure the level of vitamin A in your body. If your symptoms are severe, such as night blindness, the doctor can start treatment immediately.
The primary treatment for xerophthalmia is vitamin A therapy or supplementation, which you can take by mouth or injection. The dosage varies depending on your age and the severity of the symptom. You may also need other medications, such as antibiotics to prevent eye infections. The doctor can give you dietary advice, such as eating yellow-colored fruits and vegetables that are high in beta-carotene, to help you maintain a healthy diet. The underlying cause of the xerophthalmia will need to be treated, too.
Diagnosis
Xerophthalmia is a leading cause of preventable blindness among children worldwide. It develops when the body lacks vitamin A, also known as retinol. This eye nutrient is essential for vision, and it helps maintain healthy skin. If left untreated, the condition can lead to severe dryness of the cornea and conjunctiva, and it may even cause permanent blindness. During a physical examination, doctors will look for signs of xerophtalmia, such as dry eyes and scaly skin around the nose and lips. They may also request a blood test to check the level of vitamin A in the body.
A diet rich in foods containing vitamin A is the mainstay of treatment for xerophthalmia. A variety of foods, including liver, eggs, dairy products, green leafy vegetables, and yellow-colored fruits and vegetables, can provide adequate amounts of this eye-health nutrient. Poverty, malnutrition due to poor diet, and certain illnesses and disorders, such as celiac disease, cirrhosis of the liver, chronic diarrhoea, and radioiodine treatment for thyroid cancer, can affect vitamin A absorption and cause deficiency.

The diagnosis of xerophtalmia is made by conducting a physical examination and asking the patient questions about his or her symptoms, medical history, and eating habits. A doctor may also recommend a serum retinol test to confirm the diagnosis.
Severe xerophthalmia can lead to conjunctival xerosis with Bitot’s spots, corneal xerosis with ulceration, and even keratomalacia, which is irreversible. Xerophtalmia is most commonly seen in children from developing countries. The condition is associated with poverty, a diet deficient in animal products, and certain medical conditions, such as chronic diarrhoea, hepatitis, and radioiodine therapy for thyroid cancer, which interferes with the body’s ability to absorb vitamin A.
Getting comprehensive health insurance is an important way to prevent and treat Xerophtalmia. A well-designed plan should cover all areas of healthcare, including ophthalmology, and ensure that individuals have access to prompt and appropriate care without the burden of out-of-pocket expenses. In addition, a plan that offers a health care savings account provides an additional layer of protection for individuals against financial stress that can result from the onset of illness and disease.
Treatment
Xerophthalmia is usually not a serious condition, but it can cause pain and blurred vision. It can be caused by many things, including vitamin A deficiency; certain medicines; and diseases such as arthritis and Sjogren’s syndrome (an immune system disorder). Fortunately, there are treatments that can help treat xerophthalmia.
Symptoms of xerophthalmia usually get better after treatment starts. But the disease can progress to corneal ulceration or melting (keratomalacia), which can lead to permanent loss of vision if not treated quickly.
Doctors can diagnose xerophthalmia by taking your medical history and doing a physical exam. They may also order a standard blood test to check your vitamin A levels.
Vitamin A, or retinol, helps keep your eyes and skin healthy, and it is a vital nutrient. If you don’t have enough vitamin A, your eyelids and the surface of your cornea become dry. Eventually you can develop night blindness and white spots, called Bitot’s spots, on your eyeball. In extreme cases, the cornea can melt away if it’s not treated right away.

The most common way to treat xerophthalmia is with vitamin A supplements. The dose depends on your age and the severity of your symptoms. Your doctor can also advise you to eat yellow-coloured fruits and vegetables rich in beta-carotene, as well as green leafy vegetables, meat, and dairy products. They can also work with you to address any underlying causes of xerophthalmia.
People who are at high risk of xerophthalmia include those who have chronic diarrhea, which can rapidly deplete vitamin A stores; children who don’t receive enough calories from food; and people with diseases that prevent the body from absorbing vitamin A, such as pancreatitis or inflammatory bowel disease. Vitamin A supplements can be delivered as capsules, and they are inexpensive to produce. They can save the lives of children who would otherwise die of xerophthalmia, night blindness, and other diseases. Providing these capsules to children is an easy and effective way to prevent unnecessary suffering and deaths in the developing world. Adding the nutrient to foods like cereals, bread, and processed vegetable oils is another good way to ensure that children and adults have enough vitamin A.
Prevention
The best way to prevent xerophtalmia is to ensure that the body is getting enough Vitamin A. This can be accomplished by consuming yellow-colored fruits and vegetables rich in beta-carotene. You can also increase the amount of meat and dairy in your diet, as well as add leafy green vegetables to your meals. If you are unable to get enough Vitamin A in your diet, your doctor may prescribe vitamin A supplements.
Severe Vitamin A deficiency can lead to a constellation of eye problems, including xerophtalmia and night blindness. It is a major cause of preventable blindness in children, particularly in poverty-stricken areas, and it can lead to permanent blindness.

Vitamin A is essential for the health of the conjunctiva and cornea. Without sufficient amounts of Vitamin A, the cornea can become thick and dry. The conjunctiva may develop a dark spot in the corner of one eye called Bitot spots, and this can progress to a thickened cornea, known as xerosis.
Xerophtalmia is usually due to severe vitamin A deficiency, and it can progress to a progression of the corneal epithelium that leads to a ramollissement or ulceration. This can then cicatrise, or in the absence of treatment, lead to secondary infections that can be very serious. Xerophtalmia is the leading cause of preventable childhood blindness, and it is associated with malnutrition.
Global health organizations are working to eliminate Vitamin A deficiency in order to reduce cases of preventable blindness and illness among children. They are also focusing on improving the health of individuals by providing them with better access to healthy foods, as well as healthcare that can help to address the underlying causes of their condition. Having a health insurance policy that includes coverage for medical emergencies and other conditions can ensure that you are able to get the care that you need, even if you have a serious disease like xerophtalmia. Health insurance can also cover the costs of medications and specialist consultations, which can help to alleviate some of the financial burden. This can give you the peace of mind that you need to focus on getting the best health care possible for yourself and your family members.
