ABSTRACT
@#AIM: To evaluate the prevalence of trachoma in Shaanxi Province and provide basic data for the prevention and treatment of trachoma.<p>METHODS: Four suspected areas with high prevalence of trachoma including Kengzhen in Jiaxian Yulin, Luochuan of Yan'an, Nanzheng county of Hanzhong, Shangzhou distract in Shangluo, were selected by Blindness Prevention Office of Shaanxi Province. A random sample of 200 pupils aged 6 to 8 was examined by ophthalmic officers using the World Health Organization(WHO)simplified clinical grading system.<p>RESULTS: No infection of active trachoma was detected in 200 pupils.<p>CONCLUSION: No epidemic areas of active trachoma were found. Based on the data of this study,trachoma is no longer considered as a public health problem in Shaanxi Province.
ABSTRACT
To identify communities with high rate of active trachoma for prioritizing interventions, the sampling method of ASTRA (Acceptance Sampling Trachoma) was applied in this study in order to find the active trachoma rate among pupils at primary schools in Binh Xu yen district, Vinh Phuc province. The results showed that 3 out of 13 communes had high rates of active trachoma among primary school children. The mean rate of active trachoma among these pupils was 8.2% (95%CI: 6.5%. 9.9%). Some risk factors of active trachoma among these subjects include unsafe water for face washing, sharing face cloth, children with dirty face, unsanitary latrines, high density of home flies, and low family income.

With the support of the World Vision, in June 2004, the district Chi Linh Health Centre (Hai Duong province) co-operated with Institute of Ophthalmology to survey on blindness and some eye diseases in 3,370 people. Objectives: identify the situation of blindness and some eye diseases in Chi Linh in the year 2004; identify the trachoma prevalence after 4 years implementing the project of trachoma control in Chi Linh. Methods: cross sectional study; Target population: all people. Results of survey has shown the prevalences of blindness and some eye diseases are so high compared with the figures of country survey, the leading causes of blindness are cataract, glaucoma, corneal opacity and pterigium. Conclusion: Thank to project of trachoma control supported by WV conducted in Chi Linh from 1999, the prevalence of active trachoma now has dropped to level under the criteria of WHO on active trachoma elimination. However, the rate of trichiasis is very far from criteria of WHO. Results of survey has shown also the serious situation of blindness. That is the big challenge for health workers and ophthalmologists in Hai Duong province and Chi Linh district in order to reduce the blindness prevalence in the next years.
