INTRODUCTION: @entity10 and @entity2516 are very common conditions in the general population, and those with @entity10 often attribute their @entity158 to a visual problem. The International @entity10 Society (IHS) criteria for the classification of @entity10 includes an entity of @entity10 ( @entity10 ), but indicates that its importance is widely overestimated. OBJECTIVES: To compare overall @entity10 frequency and @entity10 frequency in healthy subjects with uncorrected or miscorrected @entity2516 and a control group. METHODS: We interviewed 105 individuals with uncorrected @entity2516 and a control group of 71 subjects (with properly corrected or without @entity2516 ) regarding their @entity10 history. We compared the occurrence of @entity10 and its diagnosis in both groups and assessed its relation to their habits of visual effort and type of @entity2516 . RESULTS: @entity10 frequency was similar in both subjects and controls. @entity10 associated with @entity2516 was the only @entity10 more common in subjects with @entity2516 than in controls (6.7% versus 0%). It was associated with @entity3467 and was unrelated to visual effort or to the severity of @entity227 . With adequate correction, 72.5% of the subjects with @entity10 and @entity2516 in their headaches, and 38% had complete remission of @entity10 . Regardless of the type of @entity10 present, @entity10 frequency was significantly reduced in these subjects (t = 2.34, P =.02). CONCLUSIONS: @entity10 associated with @entity2516 was rarely identified in individuals with @entity2516 . In those with chronic @entity10 , proper correction of @entity2516 significantly improved @entity10 complaints and did so primarily by decreasing the frequency of @entity10 episodes.
