Ocular disorders among schoolchildren in Khartoum State, Sudan

From December 2005 to June 2007, a total screening of all 1418 government primary schools in Khartoum State, Sudan, was performed to estimate ocular problems among children aged 6-15 years. We screened 671 119 children [56.7% males] for significant refractive error and other eye ailments. Ocular problems were found in 20 321 [3.03%] children. The 3 localities with highest ocular pathology were Karary [26.2%], Ummbada [21.0%] and Jabal Awlia [15.7%]. The overall prevalence of refractive error was 2.19%. Myopia was found in 10 064 [1.50%] children while 4661 [0.70%] were hyperopic. Other ocular problems included vernal keratoconjunctivitis, vitamin A deficiency, microbial conjunctivitis, strabismus and corneal opacity. Only 288 [0.04%] children were diagnosed with active trachoma: 86.5% of these were from Ummbada locality, on the periphery of the State, where transportation facilities are poor and poverty is widespread. Overall, 99% of the eye ailments identified are either treatable or preventable. To reduce these and to achieve the goals of Vision 2020, an effective and efficient school health programme is needed

Prevalence and risk indicators of myopia among schoolchildren in Amman, Jordan

We aimed to identify the prevalence and risk factors of myopia among secondary-school students in Amman. Thus 1777 [1081 males and 696 females] students aged 12-17 years old were recruited from 8 schools randomly selected from 8 different geographic locations in Amman. Data were collected by questionnaire, and self-reported myopia was checked against school medical records. The prevalence of myopia was 17.6%, with no significant difference between males and females after adjusting for other possible variables. Myopia was significantly associated with age, family history of myopia, computer use, and reading and writing outside school. Playing sports was inversely associated with myopia but there was no association with watching television
