Purpose:
To evaluate the clinical efficacy and safety of the Ex-PRESS miniature glaucoma device placed under scleral flap for the treatment of ocular hypertension in eyes that underwent vitreoretinal surgery.
Methods:
Vitrectomized patients who required glaucoma surgery for persistent ocular hypertension were included. The Ex-PRESS miniature glaucoma device was implanted under scleral flap. Postsurgical clinical outcomes and intraocular pressure (IOP) was monitored for 6 months after surgery.
Results:
At 6 months, all the patients had an IOP lower than 18 mmHg, 3 of them without topical therapy.
Conclusions:
The use of the Ex-PRESS implant under scleral flap in eyes that underwent vitreoretinal surgery was effective for lowering IOP.
