PURPOSE To evaluate the frequency, characteristics, causes, and risk factors of late recurrent retinal detachments (LRRD). METHODS The authors retrospectively analyzed 445 eyes operated consecutively for rhegmatogenous retinal detachment between 1990 and 2003 by the same surgeon. Only eyes with complete reattachment after a minimum follow-up of 6 months were included. The authors defined LRRD...

Abstract The paper examines the effect of acoustic excitation at broadband frequency range (100 - 650 Hz) on separated boundary layer developing a flat plate subjected to an adverse pressure gradient. experiment was conducted with low inlet turbulence intensity level (Tu < 1%) in order provide cleaner environment that magnifies effects frequency. It shown sound levels: SPL=125 and 135 dB, ca...

the purpose of this study was to compare the anatomic and visual outcome of primary vitrectomy with scleral buckling in patients with retinal detachment following cataract surgery. fifty-six consecutive patients with retinal detachment after cataract surgery were randomly assigned to two treatment groups: standard scleral buckling and standard three-port deep vitrectomy. successful treatment wa...

Recent evidence suggests that the adult mammalian retina is far more plastic than was previously thought. Retinal detachment induces changes beyond the degeneration of outer segments (OS). Changes in photoreceptor synapses, second- and even third-order neurons may all contribute to imperfect visual recovery that can occur after successful reattachment. Changes that occur in Müller cells have ob...

Functional, esthetic and biologic restoration of a fractured incisor often presents a daunting clinical challenge. The outcome of conventional composites, prosthodontic restorations in a young patients result in an uncertain longevity of the same. Reattachment of the fractured fragment of a tooth helps in maintaining both morphology and esthetics in a growing child until the permanent long last...

BACKGROUND Pars plana vitrectomy (PPV) is preferred surgical procedure for the management of complex rhegmatogenous retinal detachment (RRD). The purpose of this study was to evaluate the anatomical results of primary PPV for the treatment of primary complex RRD and to determine the influence of lens status, tamponading agent, preoperative proliferative vitreoretinopathy (PVR) and axial length ...

This retrospective observational case series on eyes from three patients was done to elucidate the developmental mechanism of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). The study eyes of each patients showed evidence of retinal break and diffuse retinal pigmentary change. Ultrasound biomicroscopic examination revealed vitreous fibers attached to the area around the r...

AIMS The long-term results of office-based pneumatic retinopexy (PR) using only filtered air were evaluated in a case series of rhegmatogenous retinal detachments with more than 3 years of follow-up, on average. METHODS 77 cases of primary rhegmatogenous retinal detachments arising from superior tears (mean=1.6 tears) were treated with cryopexy (n=61) or laser (next day, n=16) and intravitrea...

The presence of circulating tumor cells (CTCs) in blood predicts poor patient outcome and CTC frequency is correlated with higher risk of metastasis. Recently discovered, novel microtubule-based structures, microtentacles, can enhance reattachment of CTCs to the vasculature. Microtentacles are highly dynamic membrane protrusions formed in detached cells and occur when physical forces generated ...

Experiments are performed in a Mach-6 shock tunnel to examine the laminar-to-turbulent transition process associated with sudden increase surface angle on slender body. A cone/flare geometry 5 $^\circ$ frustum and compression angles ranging from 15 allow range of mean flow configurations, spanning an attached shock-wave/boundary-layer interaction fully separated one; unit Reynolds number is als...
