purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...

I read with great interest the article by Liu et al. on the comparison of time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT) on the treatment decision-making in the management of diabetic macular edema (DME) by repeat anti-VEGF medications. The authors find that SD-OCT does not appear to change the ultimate treatment decision or increase the level of certainty of the r...

PURPOSE To evaluate the vitreoretinal relationship in eyes with idiopathic macular disorders putatively caused by vitreomacular traction associated with early stages of age-related posterior vitreous detachment (PVD). METHODS Retrospective observational case series of 43 eyes of 40 patients diagnosed with one of several idiopathic vitreomacular conditions. Included patients had no biomicrosco...

PURPOSE To describe the clinical features and to present results of new diagnostic methods to help define the cause of the clinical syndrome of intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage (IHAPSH). DESIGN Retrospective review of patients with IHAPSH at presentation seen in 3 centers in Hawaii and Japan. METHODS We analyzed data including patient demographics,...

background with increasing incidence of traumatic fractures, the use of orthopedic intervention such as traction has increased. inappropriate traction care may cause substantial morbidity and delay the patient rehabilitation. objectives this study was conducted to evaluate the quality of care for patients with traction in the orthopedic unit of kashan's shahid beheshti hospital, kashan, iran. p...

this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...
