An experimental study has been carried out to characterize bubble formation, growth, and detachment mechanisms in a stagnant liquid column. Both bubble frequency and bubble detachment size were measured in different gas flow rates, injector diameters and orientations, submergence height, and liquid properties. Experiments were performed for air injection flow rate ranges between 200 mlph and 12...

BACKGROUND Retinal tears complicating the course of a posterior vitreous detachment (PVD) may be unique or multiple, and when multiple they may occur simultaneously or subsequently at different moments in the evolution of a PVD. The purpose of our study was to analyze the prevalence of subsequent retinal tears (SRT) in patients with a PVD, and to identify possible risk factors for SRT. METHOD...

BACKGROUD Choroidal detachment (CD) following primary rhegmatogenous retinal detachment (RRD) is a special type of RRD. The purpose of this study is to investigate the potential risk factors of RRD with CD in a Chinese population. METHODS All of 201 consecutive RRD with CD patients and 210 RRD without CD patients were enrolled in this case-control retrospective study. The clinical data from t...

PURPOSE We report a case of unilateral exudative retinal detachment in a patient with thrombotic thrombocytopenic purpura (TTP), without associated hypertension, successfully treated with plasmapheresis. CASE REPORT A 46-year-old woman with a medical history of TTP presented with unilateral exudative retinal detachment. Biological and radiological assessment eliminated other causes of exudati...

Is it retinal detachment? While most often the diagnosis of retinal detachment is straightforward, there could be confusion on occasions. Conditions that can be confused with retinal detachment are retinal oedema (as in Berlin’s oedema), retinoschisis, choroidal detachment, thick vitreous membranes (as in Uveitis), altered blood, etc. Evaluation should include careful slit lamp biomicroscopy, i...

We examined the effect of three clinically used antimicrobials on Streptococcus mutans UA159 biofilm detachment under flow conditions. Sodium fluoride (NaF) and chlorhexidine at MIC levels promoted biofilm detachment and inhibited detachment when concentrations were higher than the MIC and reduced detached-cell viability only at high concentrations. Ampicillin at all concentrations tested inhib...

The authors investigate the relationship between individual attributes and support for municipal detachment by analyzing a recent survey of Los Angeles voters. In this survey, San Fernando Valley residents were asked whether they favored detachment from Los Angeles and reorganization as a separate city. Multinomial logit regression results indicate that support for detachment is influenced by d...

AIM To report on the effectiveness of systemic steroid-pulse therapy in treating idiopathic choroidal detachment. CASE PRESENTATION Our patient developed idiopathic choroidal detachment after cataract surgery for pseudoexfoliation glaucoma and glaucoma filtration surgery. Systemic steroid-pulse therapy was performed, and the choroidal detachment resolved completely. CONCLUSION We suggest sy...

PURPOSE To describe iris atrophy, serous detachment of the ciliary body, and ocular hypotony in a patient with chronic phase of Vogt-Koyanagi-Harada (VKH) disease. METHODS Ocular examination and follow-up including digital infrared transillumination imaging of the iris was done in a 52-year-old woman with chronic phase of VKH disease. RESULTS Infrared transillumination imaging showed extens...
