Vitrectomy in Open Globe Injuries
Correct management of traumatized eye is a complicated task needing a sound evaluation of the extent of trauma. An initial history, physical examination and judicious use of Para clinical techniques to determine the extent of injury and construct a prognostic view in mind, are a prerequisite to correct surgical approach to a traumatized globe. The vitreoretinal surgeon is usually not the first ...
متن کاملPerformance Comparison of High-Speed Dual-Pneumatic Vitrectomy Cutters during Simulated Vitrectomy with Balanced Salt Solution.
PURPOSE To measure flow rate of balanced salt solution and IOP during simulated vitrectomy using two sets of high-speed dual-pneumatic probes. METHODS A closed-model eye system measured IOP and flow rate of a balanced salt solution through infusion cannula. The Constellation Vision System was tested with two sets of high-speed dual-pneumatic probes (UltraVit 23-gauge and enhanced 25+-gauge 50...
متن کاملVitreous Incarceration in Sclerotomies after Valved 23-, 25-, or 27-gauge and Nonvalved 23- or 25-gauge Macular Surgery
PURPOSE To study the patterns of vitreous incarceration at sclerotomy sites by ultrasound biomicroscopy in patients subjected to valved or nonvalved small-gauge pars plana vitrectomy. METHODS A prospective comparative study of 88 eyes affected by epiretinal membrane and macular hole. Patients were divided into four groups: valved or nonvalved 23-gauge (16 eyes each) and valved or nonvalved 25...
متن کاملNon-trocar related major retroperitoneal bleeding during laparoscopic appendectomy
Most of the reported vascular injuries in laparoscopic appendectomies occur during trocar or Veress needle insertions. As laparoscopy continues to evolve, it is essential that surgeons report unusual complications in an effort to raise awareness and guide management of any iatrogenic injury incurred during minimally-invasive procedures. We report the case of a patient who sustained a major non-...
متن کاملModified Curved Aspiration Cannulas and End-gripping Forceps for 25-gauge Vitrectomy on Highly Myopic Eyes
Pars plana vitrectomy in highly myopic eyes with an axial length (AL) of over 27.00 mm using instruments with the standard length is more challenging than surgery on eyes with an average length of 22.00 mm to 24.00 mm. One of the most difficult maneuvers is to reach the posterior pole of the eye, especially in the case of posterior staphyloma. To reach the posterior retina, the long AL of myopi...
