Abstract Details

Purpose:

To highlight precautions that should be taken for a better intraocular pressure (IOP) control with Collagen matrix implant (CM) in different gflaucoma surgeries during and after the operation

Setting:

Magrabi eye hospital, Cairo,Egypt

Methods:

Thirty-five cases of glaucoma were treated surgically with adjunctive CM a) Fifteen trabeculectomies (SST): for adult Primary Open Angle Glaucoma(POAG), b)five SST for Primary congenital glaucoma(PCG) c) fifteen Phaco-trabeculectomies for advanced POAG with cataract. Number and tightness of 10/0 nylon stitches to close the scleral flap , method of conjunctival closure, Na hyaluronate injection in AC at the end of surgery were evaluated. Postoperatively: anterior chamber(AC) depth, need for ocular massage, additional medications and additional topical steroids were assessed.

Results:

Better IOP control was obtained with slightly shallow AC postoperatively and tight conjunctival closure. Ocular massage may be needed and medications for tight closures of the scleral flap. Four SST´s and four phaco-trabeculectomies needed supplemental medications after surgeries. Failure in one SST and two phacotrabeculectomy was due to presence of additional risk factors in the patients. The rest of cases went successfully with IOP < 17 mm Hg without medications.

Conclusions:

CM is a successful adjunct to glaucoma surgeries, intraoperative and postoperative precautions should be taken to maintain proper aqueous drainage and functioning blebs and improve the degree of success. FINANCIAL INTEREST: NONE
