Background: Computer vision syndrome (CVS) is a group of eye problems that result from using the computer for a long time, it became a health problem. This syndrome is characterized by several symptoms including eyestrain, headaches and neck pain. The aim of the study was to investigate the knowledge, attitude, and practice of faculty members' about computer vision syndrome, Majmaah University, Saudi Arabia.Methods: The present study is cross-sectional study, which was conducted in Majmaah city in Sudair area in the north of Riyadh region. The study included faculty members of the College of Medicine and medical science college, Majmaah University.Results: There were 86 (74.8%) males, and 29 (25.2%) females participated in this study. The mean±SD of years using a computer by participants was 14.78±5.69 years and the mean±SD of hours spent using a computer daily was 5.25±2.2. There were 91.3% knew the bad effects of computer on the eyes, the most common symptoms resulted from long period of using computer were eyestrain 28.7% and headache 14.8%. The mean±SD score of attitude was 67.75±7.72.Conclusions: There is good knowledge, attitude and practice among faculty members about computer vision syndrome.
Jaundice is a yellowish pigmentation of the skin, the conjunctiva, and other mucous membranes caused by increased levels of bilirubin in blood beyond normal levels (hyperbilirubinemia). Jaundice occurs in neonates in 2 forms: Pathological and Physiological Jaundice. In Pathological Jaundice, high bilirubin levels can result in severe neurotoxicity, brain damage, hearing loss, muscular disorders and physical abnormalities. So measuring the exact level of bilirubin in blood in neonates is very crucial. In the past, serum bilirubin has been the preferred method of detecting hyperbilirubinemia in newborns. The ordering of serum bilirubin in neonates is based on visual evaluation by either physicians or nursing staff. Skin puncture collection of blood exposes the neonate to trauma and risk of infection. A noninvasive device for predicting serum bilirubin levels in newborns diminishes the need to do skin punctures. There are numerous studies demonstrating the transcutaneous bilirubin measurements reasonably close to serum bilirubin performed by clinical laboratories. These devices use spectrophotometry (light absorption measurements at standardized wavelengths of light) to calculate measurements. All existing methods involve transcutaneous detection of bilirubin, which is not error free, as there are various factors affecting its accuracy, like presence of hemoglobin and melanin, and maturity of skin tissue and fibres. So this gave an urge for us to develop a new technique of quantitating bilirubin level noninvasively. This study was done by analyzing conjunctival images that would imitate the blood level of bilirubin by calculating the intensity of yellow color. Machine learning techniques were applied in order to develop a system capable of predicting the bilirubin level.
BACKGROUND Visual disability is one of the most significant global health concerns. One of the studies conducted in northern part of Saudi Arabia showed that the prevalence of visual disability in adult population of 23.5 %. Very few studies have been conducted in Saudi Arabia to determine the prevalence of visual disability in the younger population. We wanted to determine the prevalence of visual disability in students studying at Qassim University. We also wanted to study and compare the utilization of compensatory rehabilitation by the students of urban and rural areas and the subjective response of beneficiaries. METHODS This study was done from September 2011 to May 2012, in the Department of Optometry in Qassim University, Buraidah, Kingdom of Saudi Arabia. A crosssectional retrospective review from the records of 642 male students referred by the deanship of student’s affairs to the optometry clinic were studied. RESULTS The prevalence of visual disability in this study was found to be 2 %. Out of the total 642 students, a significant number of students [541 (84 %)] benefited from the scheme and 101 (16 %) were declared normal. Those who were declared visually disabled (2 %) were getting compensation on monthly basis and the remaining 82 % with mild to moderate visual problems benefitted with spectacles. More number of urban students were suffering from visual abnormalities (87.6 %) as compared to rural students (45.1 %). CONCLUSIONS Though visual disability among young population at Qassim University was found to be low as compared to adult population is Saudi Arabia, it is recommended to conduct regular check-ups for visual acuity and plan to reduce the magnitude of the problem. A significant number of students utilized the compensation and rehabilitation program provided by the department of optometry. KEY WORDS Refractive Error, Blindness, Student Compensation, Qassim University, Saudi Arabia
