Purpose:
To report here a case of uncontrolled glaucoma during third-trimester of pregnancy that was treated successfully with bilateral Xen gel stent insertion.
Observations:
A 35-year-old woman presented during the third trimester of pregnancy with bilateral uncontrolled primary open angle glaucoma. Her disc examination and visual fields were consistent with advanced glaucoma. After failed Selective Laser Trabeculoplasty and maximal medical treatment, including Acetazolamide, she was treated with bilateral consecutive Xen stent surgery with successful control of her intraocular pressure.
Conclusions And Importance:
The use of Xen implant may have advantages over traditional trabeculectomy, especially during pregnancy, as the procedure is shorter, with less dependence on on-table antimetabolite and being minimally invasive with sparing of the conjunctiva.
