Basics of Vitrectomy

Basics of Vitrectomy

It is a handbook of vitreoretinal surgery and may be useful for fellows, senior residents, or junior practitioners in a retina care center. There are 14 chapters in the book. The first chapter is on the history of vitreous surgery which explains the evolution of vitreous surgery in terms of instruments and developments of techniques in simple language. In the following chapters, techniques such...

Performance of a Modified Vitrectomy Probe in Small - gauge Vitrectomy

S mall-gauge sutureless pars plana vitrectomy reduces postoperative inflammation at the sclerotomy sites in comparison with conventional 20-gauge sutured pars plana vitrectomy, thus decreasing patient discomfort postoperatively and hastening recovery.1-5 Despite the clinical advantages of smaller diameter vitrectomy systems, they pose significant challenges in vitreous removal as they decrease ...

VITRECTOMY IN CHRONIC UVEITIS

Vitrectomy was performed on 25 eyes in 21 patients with chronic uveitis from various etiologies. Postoperative follow up averaged 22.8 months with visual improvement in 24 of 25 eyes. In this retrospective study, the techniques employed and the beneficial effect of vitrectomy alone or vitrectomy combined with cataract surgery (Iensectomy in most cases) on improving vision and decreasing th...

Basics of Surface Reconstruction

In this chapter we introduce some of the properties of surfaces and their samples in three dimensions. The results developed in this chapter are used in later chapters to design algorithms for surface reconstruction and prove their guarantees. Before we talk about these results, let us explain what we mean by smooth surfaces. Consider a map π : U → V where U and V are the open sets in R2 and R3...
