In the past two decades, many advances have been made in vitrectomy instrumentation, surgical techniques, and the use of different tamponade agents. These agents serve close retinal breaks, confine eventual retinal redetachment, and prevent proliferative vitreoretinopathy (PVR). Long-acting gases and silicone oil are effective internal tamponade agents; however, because their specific gravity i...

purpose: to evaluate the success rate of vitrectomy in giant retinal tears (gtr) and factors influencing it. methods: in an interventional case series, hospital records of 68 eyes of 63 patients operated for grt were reviewed. standard three port vitrectomy plus placement of an encircling band, retinopexy, and internal tamponade was performed for all eyes. possible influencing factors including...

Cervical pregnancy can be complicated by perfuse vaginal bleeding. Mechanical compression directed at tamponing the cervical vessels can control hemostasis. There are several types of balloon catheters that have been described for cervical compression. However use of a double balloon catheter is a novel approach for cervical tamponade, as one balloon is positioned below the external cervical os...

PURPOSE Two cases with optic disc pit associated maculopathy, treated with vitrectomy surgery with internal limiting membrane peeling (ILM) and gas tamponade, are presented. METHODS Interventional case reports. RESULTS Two patients with serous macular detachment associated with a congenital optic pit underwent vitrectomy surgery, induction of posterior vitreous detachment, peeling of the IL...

Despite treatment advances, rhegmatogenous retinal detachment (RD) can have poor visual outcomes even with prompt and appropriate therapy. Pars plana vitrectomy is a leading management modality for the treatment of RD. This procedure is generally accompanied by the use of internal tamponade. Various gases and silicone oils may yield beneficial outcomes. Heavy silicone oils have been approved in...

AIMS To report a prospective two centred non-comparative interventional pilot study of a solution of perfluorohexyloctane and silicone oil (Densiron-68) as a heavier than water internal tamponade. METHODS 42 consecutive patients were recruited. The indications include proliferative vitreoretinopathy, retinal detachments arising from inferior retinal breaks, and inability to posture. RESULTS...

Objective: Cardiac tamponade is a life-threatening clinical entity that requires an emergency treatment. Cardiac tamponade can be caused both by benign and malignant diseases. A variety of methods have been described for the treatment of these cases from needle-guided pericardiocentesis, balloon-based techniques to surgical pericardiotomy. The Authors report their experience in...

We studied the hemodynamic effects of surgically induced regional cardiac tamponade in anesthetized dogs. Tamponade restricted to either the right or the left ventricle was compared with tamponade of either ventricle and both atria. Intrapericardial pressures were elevated to approximately 20 mm Hg. With tamponade of the right ventricle alone, aortic pressure rose from 161 + 3.8 to 164 + 3.4 mm...

PURPOSE The aim was to evaluate outcomes and predictors for anatomical success in macular hole (MH) surgery. MATERIALS AND METHODS This was a prospective cohort study of patients operated for idiopathic MH with stages II, III or IV. Patients underwent pars plana vitrectomy with internal limiting membrane (ILM) peeling, internal gas tamponade, and postoperative face down positioning. The prima...

PURPOSE To report the surgical outcome in seven cases of optic disc pit associated maculopathy. METHODS This was a retrospective case-note analysis of presenting features, pre- and postoperative visual acuities, surgical procedures, complications, and follow-up. The principal treatment in all the cases was pars plana vitrectomy, posterior hyaloid peel, endolaser to the papillomacular bundle t...
