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 […]
Chapter 236 – Laser Filtration Procedures
Chapter 236 – Laser Filtration Procedures MARTHA MOTUZ LEEN INTRODUCTION Laser energy can be delivered either internally (ab interno) or externally (ab externo) to produce a direct opening into the anterior chamber through limbal tissue to achieve filtration. The laser energy may be delivered using a probe (contact) or a gonioscopy lens (noncontact). […]
