Ocular changes during pregnancy and their effects on refraction

24 June 1985


The differences between the findings obtained during two complete optometric exams conducted 3 months apart with 38 non-pregnant, and 93 pregnant subjects (divided equally into three groups based on the trimester of pregnancy in which their exams were done) were compared by single factor analyses of variance, and t-tests. Refractive error, corneal curvature and thickness, accommodative amplitude, ACA ratio and fusion break ranges were not found to be significantly affected by pregnancy.
