Abstract Glaucoma is a blinding disease if no! properly diagnosed and managed. Management of glaucoma involves both medical alia surgical treatment Glaucoma filtering surgery is indicated in some cases 10 lower intraocular pressure and preserve optic nerve from damage. This type of urgery is designed to interrupt tbe iruegrity or the globe because il involves creation of a fistula. between anterior chamber and subcouj mctival space. Compllcations may lead to early OJ late failure oflhe procedure. Eftrly Failure May Resut: From: 1- Iris, vitreous, blood clot, ciliary process or lens plugging sclerostomy. 2- Retained viscoelastic substance. 3- Imperforate Descemet’s membrane. 4- Scleral flap 100 lightly sutured. 5- Ciliary or pupillary block. (Hoskins and Kas::i< J 989). Wound healing and scarring of the filtration site is responsible for the majority of late failures Ann-neoplastic dmgs like 5-tluorouracil and mitomyciu arc used to modulate wound healing in an effort 10 reduce scarring of tissues and improve success rare of filtrauon surgery, Recently advances ill laser technology enabled ophthalmic surgeons 10 perf 01111 filtration surgery with minimal tissue manipulations which may in tum result ill less scarring and better outcome of glaucoma surgery. |
