BACKGROUND: Although @entity989 ( @entity989 ) is a leading cause of childhood @entity1939 , its impact in lower income countries is not well documented. The World Health Organization has proclaimed that @entity1 at risk for @entity989 should have screening eye examinations and access to treatment. @entity1 AND METHODS: A prospective study was conducted from January 1 through December 31, 2001, at Tu Du Hospital in Ho Chi Minh City for premature @entity1 who weighed 1,500 g or less at birth or were 33 gestational weeks or younger. Serial examinations were used to classify @entity989 , and treatment outcomes were noted. RESULTS: Two hundred twenty-five consecutive @entity1 were included in the data analysis. Birth weights ranged from 900 to 2,000 g (mean, 1,512 g). Gestational ages ranged from 26 to 36 weeks (mean, 31 weeks). @entity989 was present in 103 (45.8%) of the 225 @entity1 . In @entity1 who weighed 1,250 g or less at birth, the @entity989 rate was 81.2% (26 of 32 @entity1 ). Threshold @entity989 was present in 9.3% of the 225 @entity1 but in 25% of the 32 @entity1 . Twenty-four eyes received treatment, whereas 16 lacked the family resources. Of the 24 treated eyes, 18 (75%) had a favorable outcome. Of the 16 untreated eyes, only 3 had a favorable outcome. CONCLUSIONS: @entity989 incidence is high in Vietnam, similar to that in the United States. However, larger, older @entity1 are at risk in Vietnam and the rate of severe @entity989 seems to be higher. This necessitates an @entity989 screening paradigm different from that currently used in the United States.

Incidence and severity of XXXX in Vietnam, a developing middle-income country.
