Objective: To compare ophthalmic arterial velocimetry in normotensive and preeclamptic gravidas with and without photophobia.

Methods: Ophthalmic arteries were studied by color-flow Doppler ultrasonography in 118 normotensive pregnant women, 20 gravidas with preeclampsia and no visual symptoms, and 11 with preeclampsia, photophobia, and retinal edema.

Results: The ophthalmic arterial pulsatility index (PI) correlated negatively with gestational age (y = -0.01x + 1.84, r = -0.41, P < .01). Pulsatility index in preeclamptics with photophobia (0.71 ± 0.17) was lowest among the three groups (P < .01) and was highest in normotensive pregnant women (1.41 ± 0.21, P < .01). Mean velocity in normotensive pregnant women (0.19 ± 0.05 m/second) was highest among the groups (P < .01) and was not significantly different in preeclamptic women with no visual symptoms (0.27 ± 0.03 m/second) and with photophobia (0.30 ± 0.02 m/second).

Conclusion: Preeclamptic women, especially those with photophobia, have orbital vascular vasodilation or hyper-perfusion, or both.
