“…6,7 Visual symptoms are reported in approximately 40% of patients with preeclampsia and can include decreased acuity, field defects, increased central corneal thickness and curvature, decreased corneal sensitivity, and decreased intraocular pressure. [8][9][10] Preeclampsia is associated with changes in the blood-eye barrier, choroidal thickness, and circulation, leading to varying degrees of ocular pathology.

Purpose/ObjectiveThis study aimed to investigate two‐dimensional ultrasound and shear‐wave elastography (SWE) in evaluating optic neuropathy in preeclampsia.MethodsNinety‐one singleton pregnant women (51 with preeclampsia [observation group]; 40 without complications [control group]) admitted between January 2022 and April 2022 participated in this study.Optic nerve sheath diameter (ONSD) and optic nerve stiffness measurement (ONSM) were measured using two‐dimensional ultrasound and SWE, respectively, and compared between the two groups. Receiver operating characteristic curves were employed to evaluate the performance of ONSD, ONSM, and combination (ONSD + ONSM) for diagnosing preeclampsia.ResultsThe observation (preeclampsia) group ONSD and ONSM were significantly higher than those in the control group (p < 0.05). Optimal diagnostic values for ONSD and ONSM were 4.10 mm and 11.20 kPa, respectively. Areas under the curve for diagnosing preeclampsia were 0.958 (95% confidence interval [CI], 0.926–0.990) for ONSD, 0.939 (95% CI, 0.894–0.985) for ONSM, and 0.982 (95% CI, 0.962–1.000) for ONSD + ONSM. There was no significant difference between ONSD and ONSM in diagnosing preeclampsia (p = 0.436). However, ONSD + ONSM was significantly advantageous over ONSD or ONSM alone in diagnosing preeclampsia (p = 0.033; p = 0.014).ConclusionsUltrasonic evaluation of the optic nerve can quantitatively assess optic nerve changes in pregnant women with preeclampsia.

“…To accommodate stress, pregnant women must undergo several physiological changes. Pregnancy can also cause decreased corneal sensitivity, increased central corneal thickness, increased corneal curvature [5, 6], decreased intraocular pressure [7], and changes in vision and ocular blood flow [8]. …”

Purpose: To compare the choroidal thickness (CT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in preeclamptic, healthy pregnant, and healthy nonpregnant women. Methods: Studies that focused on the CT evaluation of pregnant women were retrieved by searching PubMed, Embase, Ovid, Cochrane, and Web of Science. We used Stata 14.0 SE for the meta-analysis and presented the results as the weighted mean difference (WMD) with a corresponding 95% CI. Results: A total of 14 studies with 1,227 participants were included in our meta-analysis. The CT of the healthy pregnancies (μm, WMD = 34.19, 95% CI: 20.63–47.76) was significantly higher than that of the nonpregnancies (Test of WMD = 0: z = 4.94, p = 0.000), but the CT of the preeclampsia (μm, WMD = 54.30, 95% CI: –13.40 to 122.01) was not significantly different from the nonpregnancies (Test of WMD = 0: z = 1.57, p = 0.116). In the preeclampsia versus healthy pregnancy group, 3 studies found that the choroid was thinner with preeclampsia, only one study found the CT increased. Conclusions: This meta-analysis suggested that the CT of the healthy pregnant women was significantly higher than that of the nonpregnant women. The presence of preeclampsia might complicate this situation. Most studies found that the CT decreased in the preeclamptic patients because of the increases in the systemic vasospasm and the blood pressure, which led to no significant difference compared with the nonpregnant women.

This study aimed to evaluate the correlation between ophthalmologic factors and the serologic indicator soluble fms-like tyrosine kinase 1 (sFlt-1): placental growth factor (PlGF) ratio in patients with preeclampsia using optical coherence tomography (OCT) and OCT angiography (OCT-A). A total of 52 pregnant patients (104 eyes) diagnosed with preeclampsia were recruited during their hospital stay. The associations between the sFlt-1/PlGF ratio and chorioretinal measurements, including the choroidal thickness (CT), foveal avascular zone, vascular density, and ganglion cell layer+ were evaluated. Central and nasal subfield CT of the left eye (p = 0.039; p = 0.010) and nasal subfield CT of the right eye (p = 0.042) were lower in the high sFlt-1/PlGF ratio group (≥38). Pearson’s correlation test showed a negative correlation between the sFlt-1/PlGF ratio and central subfield CT; however, this was not statistically significant (p = 0.648). Linear regression analysis revealed a significant association between the sFlt-1/PlGF ratio and central subfield CT (β coefficient, -6.66; p = 0.01) and between sFlt-1 and central subfield CT (β coefficient, -5.65; p = 0.00). Thus, an increase in the sFlt-1/PlGF ratio resulted in a decrease in central subfield CT.
