IS VAGINAL DELIVERY HARMFUL TO PATIENTS WITH PSEUDOXANTHOMA ELASTICUM?

BACKGROUND/PURPOSE: To investigate the effect of a vaginal delivery (VD) on retinal pathology in patients with pseudoxanthoma elasticum.

METHODS

Retrospective case series. All 14 consecutive women with pseudoxanthoma elasticum who visited the ophthalmology department during pregnancy and after delivery between 2010 and 2018 were included. Prepartum and postpartum imaging consisted of color imaging, near-infrared imaging, and optical coherence tomography and was assessed on occurrence of (sub)retinal hemorrhages and change in angioid streaks.

RESULTS

Fourteen patients (15 deliveries) were included, of whom 11 patients (79%) had a VD and three patients (21%) a secondary caesarian section. Data of three patients with VD (four deliveries) could not be assessed for (sub)retinal hemorrhage within 10 weeks postpartum. The median age at delivery was 31 years (IQR 29-37). One patient with VD (9%) had a choroidal neovascularization and was treated with anti-VEGF injections before assisted delivery. All patients had angioid streaks in the central 5,500 µ m of the posterior pole of both eyes. After delivery, no patient in the VD or caesarian section group presented with progression of angioid streaks or (sub)retinal hemorrhage.

CONCLUSION

Pushing during the expulsion phase of VD seems safe in pseudoxanthoma elasticum patients without active choroidal neovascularization, and the presence of angioid streaks alone should not be an indication for elective caesarian section.
