Abstract. Attempts to noninvasively quantify the oxygen saturation of blood within the retinal vasculature date back to the 1950s. This article discusses the various approaches that have been taken to estimate the oxygen saturation in the retinal vasculature. Advantages and limitations of each are discussed. Data from human and animal subjects are also presented. [Ophthalmic Surg Lasers Imaging 2003; 34:152-164.]

After completion of this article, the reader will be able to list the various ocular changes that occur during pregnancy, summarize the ocular disturbances that occur with preeclampsia and diabetes, and describe the management of some ocular problems during pregnancy.

The diurnal variation in IOP between the 2 eyes in GS and NTG is largely concordant in approximately 90% of the time.
