- BookAndrew Chang, William F. Mieler, Masahito Ohji, editors.Summary: Recent technological advances in the diagnosis of macular disorders have enhanced our understanding of these diseases. At the same time, advances in small-gauge vitrectomy instrumentation and techniques have improved the safety and efficiency of surgery, allowing macular conditions that would have otherwise resulted in blindness to be treated effectively, preserving patients' sight. Macular surgery continues to evolve rapidly, thanks to exciting future technology trends. This book provides a detailed and up-to-date overview of the field. It begins with essential information on macular anatomy and pathophysiology, examination techniques, and surgical instrumentation. In turn, it discusses a broad range of disease processes, including macular holes, epiretinal membrane, vitreomacular traction and myopic maculopathy. The role and benefits of advanced vitrectomy techniques including submacular surgery, prosthetic vision, robotic surgery, and stem cell and gene therapy are addressed in detail. A review of perioperative care and potential complications rounds out the coverage.

- ArticleWoodward A.Int J Health Serv. 1978;8(3):491-507.The health insurance industry in the U.S. can be characterized as a concentrated industry. It has evolved into its current structure as a result of certain historical conditions, particularly those following the Great Depression. The structure of the industry has had an effect on the manner in which the industry functions and the cost increases in the health care sector. Specifically, the pricing mechanism is that of a price leader setting a limit price; health premium prices are higher than would be expected under a competitive structure. Regulation has been ineffective, because it has been dominated historically by health care providers and insurers. The costs of health care in general, and hospital care in particular, have increased beyond what would be expected as a result of "cost-pass-through."
