xerophthalmia

Children were screened for signs of xerophthalmia every 4 months.

Confirmed xerophthalmia cases were excluded from the date of diagnosis.

Some other ocular changes are referred to as xerophthalmia.

They showed, for example, that a lack of Vitamin A in the diet led to xerophthalmia.

Nonetheless, there was evidence that vitamin A supplementation reduced the incidence of xerophthalmia.

Xerophthalmia usually affects children under nine years old and "accounts for 20,000-100,000 new cases of childhood blindness each year in the developing countries."

For example, vitamin A deficiency causes symptoms such as xerophthalmia (dry eyes) and night blindness.

Xerophthalmia is estimated to affect 5 million children each year; 500,000 develop active corneal involvement, and half of these go blind.

When xerophthalmia (a major cause of blindness) persists for a long time, it results in keratomalacia.

To investigate xerophthalmia, the Schirmer test of lacrimal flow may be indicated.

Vitamin A deficiency (retinal and carotenoid precursors) causes xerophthalmia or night blindness.

"Definition of Xerophthalmia."

All children with confirmed active xerophthalmia or its sequelae (corneal scars) were withdrawn from the trial at diagnosis.

Xerophthalmia (dry eyes).

This reverses the growth-stunting effects of vitamin A deficiency, as well as early stages of xerophthalmia.

Goblet cells are responsible for secretion of mucus, and their absence results in xerophthalmia, a condition where the eyes fail to produce tears.

Without other support programmes to improve dietary and general health and hygienic conditions, capsule distribution has had poorer results than anticipated in controlling xerophthalmia.

"Xerophthalmia: A World-wide Drive for Prevention."

Xerophthalmia, keratomalacia, and complete blindness can also occur since Vitamin A has a major role in phototransduction.

Dry mouth (xerostomia) and dry eyes (xerophthalmia) can become irritating long-term problems and severely reduce the patient's quality of life.

Life was difficult following World War I, and Gerty suffered from xerophthalmia caused by severe malnutrition due to food shortages.

Causes include idiopathic, congenital alacrima, xerophthalmia, lacrimal gland ablation, and sensory denervation.

Xerophthalmia caused by a severe vitamin A deficiency is described by pathologic dryness of the conjunctiva and cornea.

VAD is responsible for 1-2 million deaths, 500,000 cases of irreversible blindness and millions of cases of xerophthalmia annually.

The prevalence of xerophthalmia at baseline was 0.7% in the Survival Study children and 1.5% in the Health Study children.
