Chapter 243 – Complications of Glaucoma Surgery and Their Management

Chapter 243 – Complications of Glaucoma Surgery and Their Management   J. WILLIAM DOYLE M. FRAN SMITH   INTRODUCTION In the ideal world, surgery proceeds smoothly and outcomes are uncomplicated. Unfortunately, in the real world, despite a surgeon’s best efforts, complications may occur. This is especially true in the field of glaucoma—glaucoma surgery, unlike many […]

Chapter 241 – Antifibrotic Agents in Glaucoma Surgery

Chapter 241 – Antifibrotic Agents in Glaucoma Surgery   1596   PENG TEE KHAW LYDIA CHANG   INTRODUCTION One of the major areas of advance in the surgical management of glaucoma over the past 20 years has been the use of antimetabolites to prevent scarring after glaucoma filtration surgery. Antimetabolites have gone from occasional use […]

Chapter 240 – Trabeculectomy

Chapter 240 – Trabeculectomy   RONALD L. FELLMAN           DEFINITION • Trabeculectomy, a guarded filtration procedure, remains the “gold standard” for long-lasting intraocular pressure reduction in uncontrolled primary glaucoma.   KEY FEATURES • Patients expect a “quick fix” but glaucoma surgery is high in risk and requires exhaustive preoperative counseling and […]

Chapter 238 – Goniotomy and Trabeculotomy

Chapter 238 – Goniotomy and Trabeculotomy   JAMES D. BRANDT   INTRODUCTION Congenital and pediatric glaucomas are generally regarded as surgical, not medical, disorders because medical therapy alone is rarely effective for these conditions and current techniques of surgery on the anterior chamber angle (goniotomy and trabeculotomy) enjoy a high degree of success. In this […]

Chapter 237 – Cyclodestructive Procedures in Glaucoma

Chapter 237 – Cyclodestructive Procedures in Glaucoma   UNDRAA ALTANGEREL MARLENE R. MOSTER TAREK M. EID   INTRODUCTION The goal of glaucoma surgery is to lower the intraocular pressure (IOP) predictably, either by maximizing outflow (as in filtration and tube-shunt surgery) or by decreasing inflow (as with cyclodestructive procedures). The destruction of the ciliary body […]
