Purpose. To report the anatomic and visual results of a new sutureless illuminated macular buckle designed for patients with macular hole retinal detachment related to high myopia (MMHRD). Design. Prospective nonrandomized comparative interventional trial. Methods. Twenty myopic eyes of 20 patients (mean age, 51.4 years; range, 35-65 years) presenting with MMHRD with a posterior staphyloma, in ...

A 76-year-old patient experienced a car accident several years earlier that resulted in the loss of his right eye (ocular prosthesis) and retinal detachment left eye, treated with scleral buckle. computed tomography scan head (Fig A) showed bilobed globe separated by ring hyperdensity (scleral buckle). Ultra-widefield fundus imaging B) demonstrated major circular indentation delimiting anterior...

Knowledge of thermal conductance of carbon nanotubes under mechanical deformation is important to characterize the robustness of carbon nanotube heat conduction. In this study, using molecular dynamic simulations, we have calculated thermal conductance of an elastically buckled single-walled carbon nanotube. A local buckle was formed by mechanically bending a carbon nanotube at an angle of 60°,...

When a thin elastic sheet crumples, the elastic energy condenses into a network of folding lines and point vertices. These folds and vertices have elastic energy densities much greater than the surrounding areas, and most of the work required to crumple the sheet is consumed in breaking the folding lines or "ridges." To understand crumpling it is then necessary to understand the strength of the...

Electrically conducting fluids can generate a magnetic dynamo when layers of fluid slide past one another, often at different rates. Known as shear, this is how the Earth and the Sun produce magnetic fields. But exactly how large-scale spatial coherence over the entire surface of the Sun can arise at high magnetic Reynolds numbers, as lines of magnetic field are dragged along by fluid flow, has...

PURPOSE To describe the clinical evolution of cases with avulsed retinal vessels without retinal detachment treated with laser or scleral buckle. METHODS Retrospective analysis of cases with avulsed retinal vessels treated between 2001-2003. Laser photocoagulation or scleral buckle was used. The minimum follow-up was 6 months. Average age was 53.6 years. RESULTS Of 13 patients, 8 were photo...
