Purpose:
To present a technique of surgical reposition of the Ex-PRESS miniature glaucoma device when dislocated in corneal limbus.
Methods:
A 54-year-old woman diagnosed with glaucoma, with a 3-month history of Ex-PRESS miniature implant, was referred to our department because of progressive intraocular pressure (IOP) rise. Slit-lamp biomicroscopy showed the posterior flange of the implant located in the corneal limbus; IOP was 34 mmHg. Surgical technique consisted of reopening of the conjunctiva and the scleral flap, excision of the corneal tissue covering the flange, and stitching the implant to the sclera with polyprolene suture.
Results:
Postoperatively, IOP rapidly reduced to 5 mmHg and was balanced to 10 mmHg in the follow-up.
Conclusions:
Corneal dislocation of the Ex-PRESS implant, when associated with ocular hypertension, needs surgical treatment. Before considering a trabeculectomy, it could be valuable to attempt an implant reposition.
