AIM To report the results of combined vitrectomy, lensectomy and silicone oil (SO) tamponade in treating primary rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD). METHODS A retrospective, consecutive and case series study of 21 subjects with concurrent RRD associated with CD was conducted. All subjects underwent a standard three-port 20G pars plana vitrectomy ...

Biofilm formation is one of the main obstacles in membrane treatment. The non-oxidizing biocide ethyl lauroyl arginate (LAE) promising for mitigating biofilm development on surfaces. However, operating conditions LAE and their impact detachment are not comprehensively understood. In this study, a real-time vitro flow cell system was utilized to observe dispersal caused by shear rate, concentrat...

A single kinesin molecule can move for hundreds of steps along a microtubule without dissociating. One hypothesis to account for this processive movement is that the binding of kinesin's two heads is coordinated so that at least one head is always bound to the microtubule. To test this hypothesis, the motility of a full-length single-headed kinesin heterodimer was examined in the in vitro micro...

PURPOSE To compare the surgical results of vitrectomy and scleral buckling for uncomplicated superior retinal detachment caused by flap tears. METHODS Included in the study were 225 patients (225 phakic eyes) undergoing primary surgery by three surgeons between January 1990 and December 1996 for superior retinal detachment caused by flap tears (138 eyes by scleral buckling, 87 eyes by vitrect...

To evaluate the efficasy of primary vitrectomy for uncomplicated rhegmatogenous retinal detachment associated with posterior hyaloid separation, a series of 63 eyes were reviewed retrospectively. The criteria for vitrectomy included not only eyes with posterior retinal breaks but also those with multiple peripheral retinal breaks. The reattachment rate was 92.1% (58 eyes) after the initial surg...

PURPOSE To use Fourier-domain anterior segment optical coherence tomography (AS-OCT)) to evaluate the main clear corneal incisions (CCIs) in microcoaxial and biaxial cataract surgery, the effects of incision enlargement, and the probable reasons for problematic healing. SETTING Atatürk Training and Research Hospital, 2nd Ophthalmology Department, Ankara, Turkey. DESIGN Cohort study. METHO...

PURPOSE To evaluate the visual outcome of combined phacoemulsification, intraocular lens implantation, and vitrectomy for macula-sparing rhegmatogenous retinal detachment. METHODS The results of combined vitrectomy with cataract extraction were retrospectively analyzed in patients with preexisting cataracts and new-onset rhegmatogenous retinal detachment. To qualify, patients must also have h...

PURPOSE To report the efficacy of 23-gauge (G) pars plana vitrectomy with silicone oil injection in rhegmatogenous retinal detachment. METHODS Retrospective chart review of consecutive patients with retinal detachment who underwent pars plana vitrectomy by one of two surgeons using distinct and consistent methods. All patients undergoing 23-G pars plana vitrectomy did not have scleral bucklin...

PURPOSE To report the clinical features and surgical outcomes of retinal detachment in mentally retarded patients. METHODS Retrospective review of records of mentally retarded patients who had retinal reattachment surgery at the authors' institutions between February 1994 and February 2000. There were 8 patients with 13 surgically treated eyes. Demographic and clinical data were abstracted fr...
