purpose: to evaluate the anatomical and functional outcomes of using heavy silicone oil as an internal tamponade for complicated cases of retinal detachment associated with proliferative vitreoretinopathy involving inferior retinal quadrants methods: 55 eyes from 55 patients with complicated retinal detachments enrolled in this interventional case series study. all eyes underwent standard three...

background: abnormal placental invasion has increased parallel with persistent rise in caesarean delivery. management relies on accurate diagnosis and delivery should be planned at an institution with appropriate expertise and resources for managing this condition.   case: we present a case of a placenta invasion anomaly which is the major risk factors of peripartum deaths. in this case we try ...

BACKGROUND Myopic foveoschisis (MF) is among the leading causes of visual loss in high myopia. However, it remains controversial whether internal limiting membrane (ILM) peeling or gas tamponade is necessary treatment option for MF. METHODS PubMed, EMBASE, CBM, CNKI, WANFANG DATA and VIP databases were systematically reviewed. Outcome indicators were myopic foveoschisis resolution rate, visua...

The purpose of this study was to determine if respiratory variation and/or absolute size of echocardiographically measured right or left ventricular internal dimension at end-diastole (RVIDd or LIVIDd) are accurate indicators of the presence or severity of cardiac tamponade. We measured RVIDd or LVIDd by echocardiography in nine closed-chest, spontaneously breathing dogs in control and during h...

Central venous catheter (CVC) insertion rarely causes cardiac tamponade due to perforation. Although it is a rare complication, it can be lethal if not identified early. We report a case of cardiac tamponade caused by internal jugular (IJ) central venous catheter (CVC) insertion using a soft J-tipped guide wire which is considered safe and rarely implicated with cardiac tamponade. A bedside tra...

Delayed cardiac tamponade after a penetrating chest injury is a rare complication. The clinical diagnosis of tamponade is facilitated with imaging. We present a case report of a 23-year-old male who was brought to emergency after multiple stab wounds to the chest. After resuscitation and repair of laceration of right internal mammary artery and right ventricle, he was discharged but later retur...

We analysed the nitrous oxide composition of the intraocular gas bubble following vitrectomy and fluid-air exchange in 12 patients. Samples were taken under standardised conditions at 20 minutes after completion of the fluid-air exchange. Analysis was conducted by a Medishield MS2 mass spectrometer. The percentage composition of nitrous oxide in the samples varied between 4 and 21% (mean 9%). T...

diagnosis of cardiac tamponade has been mainly based on clinical features and echocardiography. however, ct may be an initial tool for the evaluation of cardiac tamponade because cutting edge ct is increasingly being installed in the emergency room, and presentation of cardiac tamponade can be nonspecific. importantly, ct has better spatial resolution compared with echocardiography. thus, ident...

The purpose of this study is to evaluate the anatomic and visual outcomes, as well as the complications, of macular hole surgery with SF6-gas tamponade versus silicone-oil tamponade. Fifty-four (54) eyes with idiopathic macular hole underwent vitrectomy and peeling of the internal limiting membrane (ILM) around the hole. Nineteen (19) eyes were treated with SF6-gas tamponade (group 1) and the o...
