To determine the causes of any vision change reported during pregnancy.
An obstetrical practice in Southampton, New York.
Two hundred forty pregnant women were asked whether they had any alteration in vision. Those who agreed to take part in the study (83) and who complained of vision changes (12) were matched with the next patient seen in the practice who was asymptomatic. OBSERVATION. All patients underwent a complete ophthalmic examination, including refraction. Those who had alterations in vision status were seen again after delivery.
Changes in visual acuity and refractive error during pregnancy.
All women who complained of visual changes were found to have experienced a myopic shift from pre-pregnancy levels. (0.87+/-0.3 diopters in the right eye ( P<0.0001) and 0.98+/-0.3 diopters in the left eye ( P<0.0001). Post partum, all subjects returned to near pre-pregnancy levels of myopia.
This report links worsening of myopia to pregnancy. The causes of this myopic shift are not readily evident and merit further investigation.
确定孕期报告的任何视力变化的原因。
纽约南安普敦的一家产科诊所。
询问了240名孕妇是否有视力改变。同意参与研究的人（83名）以及主诉视力变化的人（12名）与诊所中下一位无症状的患者进行匹配。观察：所有患者均接受了包括验光在内的全面眼科检查。视力状态有改变的患者在产后再次接受检查。
孕期视力和屈光不正的变化。
所有主诉视力变化的女性均出现了从孕前水平的近视性偏移。右眼为0.87±0.3屈光度（P<0.0001），左眼为0.98±0.3屈光度（P<0.0001）。产后，所有受试者的近视程度均恢复到接近孕前水平。
本报告将近视加重与怀孕联系起来。这种近视性偏移的原因尚不明确，值得进一步研究。
