Presurgical Evaluation
Vitreous surgery has been applied successfully to a wide spectrum of ocular diseases. The complex set of biologic, systemic risk, technique, and technology considerations confronting the surgeon creates a difficult…
Vitrectomy for Retinal Detachment
Figure 14.1 Bipolar diathermy is used to mark the site prior to making drainage retinotomy to facilitate finding the site after retina reattached by internal drainage of SRF and fluid-air…
Treatment of Choroidal Neovascular Membranes
The management of choroidal neovascular (CNV) membranes in age-related macular degeneration (AMD), ocular histoplasmosis syndrome, myopia, and uveitis has advanced greatly in the past few years. In general terms, there…
Pediatric Traction Retinal Detachments
RETINAL DETACHMENTS Diverse disease processes may create traction retinal detachments in the pediatric age group. Special approaches are required to manage these difficult problems. These young patients have many years…
Constellation Architecture
The Constellation is the culmination of over three decades of evolutionary development of vitreous cutters and fluidics, new and improved tools, illumination sources, phaco technology, systems integration, efficiency systems, and…
Giant Breaks
Giant retinal breaks are traditionally defined as breaks extending for greater than 90 degrees. Because of the propensity of the retina to fold over, surgical management of these detachments was…
Macular Holes
Until 1991, it was thought that macular holes were untreatable and their pathogenesis was unknown. In that year, Kelly and Wendel developed the concept of using vitrectomy and fluid-gas exchange…
Membranes and Vitreomacular Traction Syndrome
Membranes on the macular surface can result from several pathogenic mechanisms with the common theme of tissue damage and subsequent repair (1–5). Epimacular membranes (EMMs) are hypocellular, largely collagen structures….
20-Gauge Sutured Wound Construction and Closure
Whereas 25-gauge vitrectomy is usually performed transconjunctivally with trocar-cannula systems, 20-gauge vitrectomy usually requires conjunctival incision, exposure of the anterior sclera, and sclera closure and conjunctival reapproximation with sutures. Despite…
Management of Suprachoroidal Hemorrhage
Suprachoroidal hemorrhage is a devastating complication of intraocular surgery. This complication is very difficult to anticipate, prevent, and manage (1–5) (Fig. 30.1). Intraoperative management is complex, as is the decision…
