In order to determine which layers of the corneal stroma bear the stress of the intraocular pressure, 6.0-mm nonpenetrating trephine incisions were made centrally in one eye of each of 16 adult albino rabbits. After epithelial healing, the central corneal thickness was measured over 3 hr at 50 mmHg intraocular pressure in both eyes of the anesthetized rabbits. The animals were then killed and t...

The literature on combined surgery in the treatment of patients with cataract and primary open-angle glaucoma was comprehensively studied, and all aspects and variations of the combined procedure were assessed. Phacoemulsification has improved the success rate and reduced the complication rate previously associated with extracapsular cataract extraction combined with trabeculectomy. A mean redu...

A number of armed assaults on public officials occurred in the early 1970s, which prompted the Lightweight Soft Body Armor Program to develop modern, concealable, soft body armor. Methodology needed to be developed to (1) determine the effectiveness of the soft body armor to stop bullet penetration and (2) assess the potential injury from nonpenetrating blunt impacts to the body. Extensive rese...

Tricuspid regurgitation (TR) caused by nonpenetrating trauma of the chest is rare. It has been seen more frequently in recent years, presumably because of the increase in automobile accidents and the availability of better diagnostic facilities. Since the first description by Williams in 1829, 31 cases have been reported, but surgical or necropsy proof of the condition was obtained in 23 only.1...

introduction: focused assessment with sonography for trauma (fast) is a highly effective first screening tool for initial classification of abdominal trauma patients. the present study was designed to evaluate the outcome of patients with blunt abdominal trauma and positive fast findings. methods: the present prospective cross-sectional study was done on patients over 7 years old with normal ab...

Posttraumatic hematoma of the face is common and usually self-limiting in nature. We report an unusual massive expanding hematoma of the chin within 9 h following a blunt trauma with no associated injuries or fracture.
