Phacoemulsification and Vitrectomy with the Erbium: or Neodymium:YAG-Laser

2002

Summary There are an increasing number of applications for Erbium:YAG and Neodymium:YAG lasers in opthalmology. Laser phacoemulsification and Erbium-laser vitrectomy are of major interest. We report the underlying technology and more than 1-year-experience using the PHACOLASE (Carl Zeiss Meditec, Jena, Germany, 10–100 Hz frequency, 5–50 mJ single pulse energy) for phacoemulsification and pars plana vitrectomy and the Lyla-Dodick laser photolysis (A.R.C. Laser, Eckental-Forth, Germany, 1–20 Hz, up to 8 mJ single pulse energy). The Erbium:YAG laser and Neodymium:YAG laser enabled us to extract lenses with up to medium hard nuclei. Moreover, the Erbium laser enabled fast vitrectomy with little…

Preoperative, Intraoperative and Postoperative Corticosteroid Use as an Adjunctive Treatment for Rhegmatogenous Retinal Detachment

2020

The treatment for rhegmatogenous retinal detachment (RRD) is surgery, including pars plana vitrectomy (PPV) and scleral buckling (SB). Despite surgical advances, degeneration of the photoreceptors and post-operative complications, such as proliferative vitreoretinopathy (PVR), often occurs as the result of inflammation, preventing complete visual recovery or causing RRD recurrence. There is increasing evidence that in the presence of RRD, the activation of inflammatory processes occurs and the surgery itself induces an inflammatory response. This comprehensive review focuses on the use of different formulations of corticosteroids (CCS), as an adjunctive treatment to surgery, either PPV or S…

Endogene Candida-Endophthalmitis bei Patienten mit schweren Allgemeinerkrankungen

2005

Background: Endogenous Candida endophthalmitis is a rare disease with increasing frequency and poor prognosis. Patients and Methods: The course of endogenous Candida endophthalmitis in 7 eyes of 5 patients (age 2 months to 76 years) was evaluated. Underlying general diseases were diagnosed as colon cancer, diverticulitis, pancreatic insufficiency (with subclavian catheter), ileus and diabetes mellitus. Diagnosis was based on the very typical ocular feature combined with a positive blood or vitreous culture. Intensive antimycotic drug therapy was initiated and pars plana vitrectomy performed as soon as possible. Results: The delay between onset of ocular symptoms and diagnosis amounted to on…

Pars-Plana-Vitrektomie bei diabetischen Traktionsamotiones mit Foramen

2000

PURPOSE: To evaluate results and prognostic factors of pars-plana vitrectomy (ppv) using membrane peeling and C2F6-gas for diabetic traction retinal detachments with a hole. METHODS: We retrospectively reviewed the healing course of 84 eyes, which were treated in this way consecutively (follow-up 6-32 month). C2F6 was always used in case of a retinal hole at the posterior pole or in the upper part of the eye. The influence of HBA1c, type of diabetes, preoperative visual acuity, preoperative laser-coagulation and macular status over treatment results and rate of complications were studied using multivariate logistic regression analysis. RESULTS: Preoperatively 56% of the eyes showed premacul…

Vitrectomía enzimática por inyección intravítrea de plasmina autóloga como tratamiento inicial de las membranas epirretinianas maculares y el síndrom…

2009

espanolObjetivo: Determinar si la inyeccion intravitrea de plasmina es efectiva en el tratamiento de las membranas epirretinianas maculares (MEM) y el sindrome de traccion vitreomacular (STVM), sin necesidad de asociar vitrectomia quirurgica. Material y metodo Diseno: Estudio piloto prospectivo, de intervencion, serie de casos. Pacientes: Siete pacientes, cuatro con membrana epirretiniana macular y tres con sindrome de traccion vitreomacular. Tratamiento: Inyeccion intravitrea de 0,2 ml de plasmina autologa bajo anestesia topica. La plasmina fue obtenida por un metodo simplificado modificado por adiccion de uroquinasa. Principales medidas: Grado de separacion de la membrana epirretiniana de…

Vascular changes after vitrectomy for rhegmatogenous retinal detachment: optical coherence tomography angiography study

2020

Purpose: To analyse the postoperative foveal avascular zone (FAZ) area, superficial vessel density (SVD) and deep vessel density (DVD) and their correlation with functional (best-corrected visual acuity, BCVA) and anatomical outcomes (foveal macular thickness, FMT) after surgery for rhegmatogenous retinal detachment (RRD) repair. Method: Patients with RRD eyes, successfully treated with a single pars plana vitrectomy (PPV) with gas tamponade and a minimum 12 months follow-up, were re-examined. Foveal avascular zone (FAZ) area, SVD, DVD and FMT were evaluated by using optical coherence tomography angiography (OCTA) and compared to fellow eye. Results: Fifty-six patients with macula-on and 37…

Ultramicro-trauma in the endometrial-myometrial junctional zone and pale cell migration in adenomyosis

2015

Objective To determine if ultrastructural tissue trauma occurs in the junctional zone in uteri in adenomyosis. Design A case-control experimental study. Setting Endometriosis research center. Patient(s) Twelve uteri with adenomyosis, and 9 uteri without adenomyosis, were gained during laparoscopy-assisted vaginal hysterectomy. Intervention(s) Transmission electron microscopic study of the junctional zone, as well as immunohistochemical staining for epithelial cadherin, and van Gieson staining and immunofluorescence for CD45 and CD68. Main Outcome Measure(s) Analysis of the electron microscopy photos and the immunoreactive scores of the staining. Result(s) The inner myometrial muscle fibers …

Wertigkeit der Abradathistologie von Endometriumkarzinomen

2002

Objective: We compared immunohistological examination of endometrium biopsy specimen with the results of the immunohistological examination of tumor specimen to analyse the valence of this preoperative examination according to the clinico-pathological findings and overall-survival. Material and Method: Between 1985 and 1995 193 women were treated of an endometrial carcinoma at the University hospital Mainz. In this group we evaluated 41 patients with enough preoperative endometrial biopsy material for a retrospective immunohistochemical analysis and complete follow-up data. The materials from diagnostic curettage were stained and analysed for oestrogen and progesterone receptor status and f…
