Xerophthalmia can be associated with systemic diseases such as Sjögrens syndrome, systemic lupus erythematosus, rheumatoid arthritis, scleroderma, sarcoidosis, amyloidosis, and hypothyroidism; deficiency of vitamin A; and the use of some medications including antihistamines, nasal decongestants, tranquilizers, and anti-depressant drugs. When xerophthalmia is due to vitamin A deficiency, the condition begins with night blindness and conjunctival xerosis (dryness of the eye membranes) and progresses to corneal xerosis (dryness of the cornea), and, in the late stages, to keratomalacia (softening of the cornea). Other forms of dry eye are associated with aging, poor lid closure, scarring from previous injury, or autoimmune diseases such as rheumatoid arthritis, and these can all cause chronic conjunctivitis. ...
Purpose:To identify children aged 0-72 months with blinding xerophthalmia in the North West Frontier Province (NWFP) and its adjoining Federally Administered Tribal Areas (FATA) in Pakistan, using a new surveillance system, and to describe socio-economic and other characteristics of reported cases. Methods: All ophthalmologists in district headquarter hospitals in NWFP and agency headquarter hospitals in FATA were requested to participate in a surveillance programme for the detection of blinding xerophthalmia (corneal xerosis, corneal ulcers, keratomalacia and corneal scars related to vitamin A deficiency) for children aged 0-72 months. The surveillance included reporting of each case of blinding xerophthalmia presenting to the participating eye units over a period of 12 months and recording their socio-economic and other related characteristics. Results: Seventy six cases of blinding xerophthalmia were reported and there was almost no gender difference. Children came from 19 of 31 districts and
Background. Sjögrens syndrome (SS) is an autoimmune exocrinopathy characterised by a lymphoplasmacytic infiltration of the exocrine glands. Both xerophthalmia and xerostomia are the most common manifestations of the disease. However serious organ damage such as, pulmonary and neurological involvement, can occur. The prevalence of neurological manifestations of SS varies between 0% and 70% (average 20%), which is largely dominated by peripheral neuropathies¹. The cranial nerve involvement, especially when it is isolated, represents a rare facet of the peripheral neuropathy.. Observation. We report the case of a 62-year-old patient with no medical history, referred to the internal medicine department with a 6 years history of dry mouth and xerophthalmia. No other complaints were reported.. The mouth examination showed a fissured, smooth and left deviated tongue without evidence of atrophy or fasciculation (figure 1). The rest of the oropharyngeal examination was unremarkable with no angina or ...
To the Editor:. A 60-year-old woman was seen at the outpatient clinic of the Department of Rheumatology because of increased complaints of xerophthalmia. In 1997, she had already been diagnosed with Sjögrens syndrome (SS) based on xerophthalmia, xerostomia, bilateral salivary gland swelling, and positive sialography showing chronic inflammation without local obstruction. Antinuclear antibodies (ANA) and anti-SSA/SSB were negative. Because of persistent progressive salivary gland swelling at that time, a total bilateral submandibular gland excision was performed as development of non-Hodgkin lymphoma as a complication of SS was suspected. Histology showed sialoadenitis as seen in SS without signs of lymphoma. In 2002, a renal biopsy performed because of increased creatinine level without proteinuria revealed focal global glomerulosclerosis with interstitial nephritis due to SS or chronic ischemia. In an attempt to treat possible active interstitial nephritis due to SS, she was treated with 30 ...

Vitamin A:. The level of vitamin A in the plasma or serum is a reflection of the quantities of vitamin A and carotene ingested and absorbed by the intestine (carotene is converted to vitamin A by intestine absorptive cells and hepatocytes).. Vitamin A plays an essential role in the function of the retina (adaptation to dim light), is necessary for growth and differentiation of epithelial tissue, and is required for growth of bone, reproduction, and embryonic development. Together with certain carotenoids, vitamin A enhances immune function, reducing the consequences of some infectious diseases.. Degenerative changes in eyes and skin are commonly observed in vitamin A deficiency. Poor adaptation of vision to darkness (night blindness) is an early symptom that may be followed by degenerative changes in the retina. In developing countries, vitamin A deficiency is the principal preventable cause of blindness. Severe or prolonged deficiency leads to dry eye (xerophthalmia) that can result in corneal ...
It is necessary for low light and colour vision, as it is found in the retina of the eye. Vitamin A is used in the treatment of Rhodopsin-related diseases. Night blindness and retinitis pigmentosa are two main health conditions associated with the defficiency of Vitamin A. This particular vitamin has an essential role in the ocular system of the body, however, the rate of cone photoreceptors degenerated can be slowed as the result of the use of oral supplements[1]. Deficiency is more common within developing countries particularly during infancy when they are not getting sufficient amounts in breast milk. Common symptoms include xerophthalmia, anaemia and increased susceptibility of infection[2][3]. ...
Ocular signs of vitamin A deficiency are associated with increased mortality among children aged 6 months or older.1 Supplementation with vitamin A can significantly reduce total mortality.2-8 The impact of supplementation is only clear in children aged 6 months or older. It was assumed that breast feeding protected infants from vitamin A deficiency and that clinical signs of xerophthalmia appeared only after the onset of weaning or incorrect bottle feeding.1 Recent evidence challenges these assumptions. Infants are born withlow stores of vitamin A and depend on feeding to build body stores.9-11 If the mothers breast milk has a low concentration of vitamin A, as found in many women in developing countries, the infant will be unable to meet daily requirements and increase body reserves.12. Supplementation of women post partum can improve the concentration of vitamin A in their blood and breast milk, but data on the impact of supplementing infants early with vitamin A on survival are ...
TY - JOUR. T1 - Urinary excretion of retinol in children with acute diarrhea. AU - Alvarez, J. O.. AU - Salazar-Lindo, E.. AU - Kohatsu, J.. AU - Miranda, P.. AU - Stephensen, C. B.. PY - 1995. Y1 - 1995. N2 - Acute infections of childhood are associated with an increased rate of xerophthalmia, apparently due to depletion of vitamin A stores. The mechanism responsible for this is not known. Recently, it has been reported that severe infections in adult patients (ie, sepsis and pneumonia) result in excretion of large quantities of retinol in the urine. In 44 children hospitalized for treatment of acute diarrhea we found mean urinary excretions of 1.44 μmol retinol/24 h on day 1 of hospitalization, 0.62 μmol retinol/24 h on day 2, and 0.23 μmol/24 h on day 3. Healthy control subjects matched for age did not excrete measurable amounts of retinol in the urine. Retinol excretion was associated strongly with rotavirus diarrhea and presence of fever. Furthermore, serum retinol concentration was ...
The third goal specified in the contract is perhaps the most important. It addresses the important planning question of what we should expect in a new programme in a new setting. The response can be divided into two sub-questions: in what population setting(s) can one expect vitamin A to be effective and what is the range of effect to be expected?. Where is improvement of vitamin A status most likely to affect morbidity and mortality?. The obvious answer to this question is: Where vitamin A deficiency is now a serious problem. For the mortality trials, all of which were conducted in settings where it was assumed vitamin A was a public health problem under the WHO definition, we attempted to ask about population-level predictors of the relative effect. Statistical power was very low for these analyses of the predictors of response (mortality of control group, xerophthalmia, stunting, wasting) since study was the unit of analysis (n = 8). Individual-level data might have uncovered more subtle ...

Dr. Alfred Sommers contributions to our understanding of epidemiology and consequences of malnutrition are marked by innovation and persistence. The first, soon after completing his basic medical education, was the pioneering demonstration that simple anthropometrical measurements were closely associated with subsequent childhood death. These and other indices are now routinely employed in nutritional screening, measurement, and surveillance programs.. Dr. Sommers major, long-term continuing research interest involves the cause, magnitude, consequences, and control of vitamin A deficiency and those of related micronutrients. These investigations began in earnest in the mid1970s with a complex series of intervention trials that Dr. Sommer conducted in Indonesia (1976-1980). In addition to revealing the epidemiologic characteristics and determinants of deficiency among young children, Dr. Sommer documented the complete clinical spectrum of xerophthalmia, from mild nightblindness, retinal ...

Vitamin A is essential for normal vision as well as proper bone growth, healthy skin, and protection of the mucous membranes of the digestive, respiratory, and urinary tracts against infection. In some developing countries, vitamin A deficiency in the diet and associated keratomalacia are a major cause of childhood blindness. In such regions, vitamin A deficiency often occurs as part of nonselective general malnutrition in infants and young children.. Lack of tears causes extreme dryness of the eyes, and foamy Bitots spots appear on the bulbar conjunctiva. ...
Ophthalmic compositions having negligible side effects on the heart can be obtained by using as the active ingredient an adrenergic β receptor agonist having a high selectivity toward adrenergic β2 receptor. These compositions are usable as preventives or therapeutics for xerophthalmic disorder and keratoconjunctival disorder.
a. Number of cases.. Vitamin-A deficiency (xerophthalmia and keratomalacia). Untreated vitamin-A deficiency leads to irreversible blindness and death. Growing children are at the greatest risk of developing signs of xerophthalmia because of their higher vitamin-A requirement and also because they have a higher rate of infections. A close association between even moderate vitamin-A deficiency and increased morbidity and mortality from respiratory and gastro-intestinal infections has been reported [8].. The lead time for the signs to develop depends on the level of vitamin A stored in the body. Refugees most often arrive in camps with low vitamin-A stores after subsisting on a deficient diet prior to and during their exodus, and during initial periods in the country of asylum. Thus, the lead time for developing xerophthalmia in refugees can be expected to be shorter than in a population that suffers vitamin-A deficiency without previous malnutrition.. Iron deficiency (anaemia). Anaemia can have ...

Results Non-sicca SS patients were younger at diagnosis (45.9±14.8 vs. 61.4±15.1 years, p,0.001), had a shorter disease duration (1.1±1.5 vs. 6.9±8.9 years, p,0.001), and had a higher rate of positive anti-SS-A/Ro antibody (100 vs. 74.3%, p=0.023), and a lower rate of positive anti-centromere antibody (6.3 vs. 44.3%, p=0.005). Subjective xerophthalmia and xerostomia rates were similar between the groups, but fewer non-sicca SS patients had sicca symptoms as chief complaints (18.8 vs. 58.6%, p=0.004). There were no significant differences in focus score, leukocyte and lymphocyte counts, serum IgG levels, and positive rheumatoid factor and antinuclear antibody levels. The maximum European League Against Rheumatism Sjögrens Syndrome Disease Activity Index (ESSDAI) score during follow-up showed no significant difference (3.34±4.27 in non-sicca SS vs. 3.83±4.68 in sicca SS, p=0.30). However, more non-sicca SS patients had ESSDAI scores ≧ 1 (100 vs. 71.4%, p=0.015), a positive correlation ...

A UC Davis Health System Eye Center study found that scleral lenses, which rest beyond the limits of the cornea and cover the white part of the eye (sclera), were a good alternative for patients with corneal abnormalities whose vision could not be corrected with other types of contact lenses or glasses. The study was published in the journal Eye & Contact Lens.

Severe dry eye is a debilitating ocular disease resulting in loss of vision, reduced day-to-day function and significant discomfort. Tear substitutes are an important part of the treatment of all patients, however, even with aggressive us, the corneal(ocular)surface often remains very irregular due to poor surface healing.. The agent being evaluated in this study, Thymosin Beta 4, promotes healing of the corneal surface and has been studied in patients with recalcitrant corneal ulcers and erosions with significant success (Arch Ophthalmol. 2010;128(5):636-638., Ann of the NY Acad of Sci, May, 2010).. The study hypothesis is that Thymosin Beta 4, in its role as a modulator of corneal surface healing, may be able to promote healing of the corneal surface allowing for more conventional modalities to take over and maintain a smooth and regular ocular surface. The investigators hope to be able to demonstrate an improvement in visual acuity, surface healing and a reduction in dry-eye related symptoms. ...
Children ages 5 and under who suffer from acute malnutrition will have physiological and mental detriments that will impact them their entire lives. This limits their opportunity, as well as the opportunity for future generations. Can you see how this has a domino-effect?. What physical effects does acute malnutrition have on children? When the body isnt getting the proper nourishment, it adapts by slowing down the processes needed for proper organ function, as well as tissue and cell maintenance and reducing physical activity. Their bodies actually begin to EAT at its own tissues in search of the nutrients and energy needed to survive. The first targets? Muscle and body fat. Metablolism slows, the immune system is weakened, kidney function is impaired, and thermal regulation is disrupted.. Moderate acute malnutrition is characterized by crucial deficiencies in vitamins and minerals. Conditions such as anemia (from a lack of iron), goiter (from a lack of iodine), and xerophthalmia (from a lack ...
OBJECTIVE: To assess the prevalence and clinical and immunological significance of anticentromere antibodies (ACA) in patients with primary Sjögrens syndrome (pSS). METHODS: We retrospectively investigated the prevalence of ACA in patients with SS. We compared ACA-positive SS patients with ACA-negative pSS patients. RESULTS: The prevalence of ACA among patients with pSS was 4.7% (10/212). Among the patients with SS and an associated autoimmune disease, 10 patients had ACA and limited cutaneous sclerosis (SSc). Clinical and immunological patterns did not differ between the 10 pSS patients with ACA alone and the 10 SS patients with ACA and SSc, except for presence of limited cutaneous SSc (lcSSc). Moreover, all ACA-positive sera recognized centromere protein-B on ELISA, regardless of the presence of SSc. The entire SS-ACA group (n = 20) showed greater frequency of Raynauds phenomenon, objective xerophthalmia, peripheral neuropathy, and additional autoimmune disorders, especially primary biliary ...
Reading is a critical life skill, essential for communicating with others, keeping up with the news, understanding instructions, succeeding at work, using a computer, or simply for enjoyment. Vision problems can seriously impede reading and make these necessary tasks extremely difficult and, in some cases, impossible.. Our BostonSight® PROSE patients with moderate to severe dry eye disease know firsthand the impact of their symptoms on their ability to read the printed word. In fact, a 2010 survey conducted by Boston Foundation for Sight found that 81% of survey respondents with severe dry eye reported difficulty reading regular print newspapers, magazines, or websites. Dry eye contributes to problems with visual acuity but until recently most data with regard to the impact on reading has been self-reported by patients. In addition, the pain and photophobia (light-sensitivity) that result from dry eye also make reading a challenge. A recent study confirms what those who suffer from moderate to ...
This study aims at the development of non-contact dry eye diagnosis based on an infrared thermal imager system, which was used to measure the cooling of the ocular surface temperature of normal and dry eye patients. A total of 108 subjects were measured, including 26 normal and 82 dry eye patients. We have observed that the dry eye patients have a fast cooling of the ocular surface temperature than the normal control group. We have developed a simplified algorithm for calculating the temperature decay constant of the ocular surface for discriminating between normal and dry eye. This study shows the diagnostic of dry eye syndrome by the infrared thermal imager system has reached a sensitivity of 79.3%, a specificity of 75%, and the area under the ROC curve 0.841. The infrared thermal imager system has a great potential to be developed for dry eye screening with the advantages of non-contact, fast, and convenient implementation ...
Night blindness is a type of vision impairment that prevents people from seeing well at night. Also called nyctalopia, night blindness implies that those afflicted with the condition cannot see at all at night.

Vitamin A deficiency, which affects about 100 million young children worldwide, was long known to cause blindness. But it has become increasingly clear that even mild vitamin A deficiency also impairs the immune system, reducing childrens resistance to diarrhoea, which kills 2.2 million children a year, and measles, which kills nearly 1 million annually. And new findings strongly suggest that vitamin A deficiency is a cause of maternal mortality as well, especially among women in impoverished regions (Panel 1).. At its most basic level, malnutrition is a consequence of disease and inadequate dietary intake, which usually occur in a debilitating and often lethal combination. But many more elements -- social, political, economic, cultural -- are involved beyond the physiological.. Discrimination and violence against women are major causes of malnutrition.. Women are the principal providers of nourishment during the most crucial periods of childrens development, but the caring practices vital to ...
