Objective: To describe results of barrier laser photocoagulation in preventing progression of recurrent retinal detachment. Methodology: Prospective review of five patients with recurrent retinal detachment confined to the peripheral inferior retina. Three rows of barrier argon laser photocoagulation of moderate intensity white burns were performed. Patients were observed carefully after laser ...

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...
