Filter by:The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
31 patients were included in the study,15 cases with ERM in silicone filled eyes and 16 eyes with idiopathic ERM
Objective: to evaluate anatomical and visual outcomes of 23-gauge vitrectomy for retinal detachment with silicone oil injection in fifty cases. The rate of recurrence, the incidence of proliferative vitreoretinopathy (PVR) and the value of risk factors. Participants and Methods: fifty cases with RD with mixture of epiretinal and subretinal membranes were collected. Pars plan vitrectomy, 23gauge vitrectomy were done to these cases, then silicone oil removed 6 weeks after primary surgery. Main Outcome Measures: The anatomical success rate,the failure rate ,the rate of retinal breaks in both groups, and reproliferation rate.
Purpose To evaluate the efficacy of perfluorocarbone liquids (PFCLs) for tamponading lower retinal breaks to achieve retinal reattachment in eyes of retinal detachment with proliferative vitreoretinopathy (PVR) and inferior breaks. Patients and methods The study was prospective non comparative interventional study. It included thirty eyes of 30 patients suffering from retinal detachment with proliferative vitreoretinopathy and inferior breaks attending the ophthalmology department at Minia University Hospital. The mean age was 50.2± 10.63 years, 18 females and 12 males. Double retinal tamponade procedure were done and the patients were followed for one year. The primary outcome was to achieve successful retinal reattachment and the secondary outcome is to achieve improvement in the postoperative visual acuity.
Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments (RRDs) especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. There is no study in the scientific literature comparing the rate of retinal displacement and its association with visual function, including metamorphopsia, in patients undergoing different procedures for RRD repair. Based on the recently published PIVOT trial, patients who underwent Pneumatic Retinopexy (PnR) had less vertical distortion at 12 months than patients who had Pars Plana Vitrectomy (PPV). It is hypothesized that PnR will cause less retinal displacement than PPV for patients with macula-off primary retinal detachment.
Internal limiting membrane peeling is performed during vitrectomy for macular diseases such as macular holes, macular edema due to diabetic retinopathy and retinal vein occlusion. The incidence of epiretinal membrane formation after vitrectomy for rhegmatogenous detachment has been reported to range from 4.4% to 12.8%. In this study, the efficacy and safety of internal limiting membrane peeling will be studied in vitrectomy for rhegmatogenous retinal detachment and if it is essential to peel it in those cases or not.
To compare the efficacy and safety outcomes of scleral buckling (SB) and drainage-injection-pneumoretinopexy (DIP), a modified pneumatic retinopexy technique, in which, before injecting the gas, the drainage of the subretinal fluid is performed with a simultaneous injection of balanced salt solution (BSS) in the vitreous chamber, for the treatment of severe superior bullous rhegmatogenous retinal detachment (SBRD).
Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye. The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many microstructures of the eye: photoreceptors, vessels, nerve bundles in the retina, cells and nerves in the cornea. The use of a high-speed acquisition imaging system makes it possible to detect functional measurements such as the speed of blood flow. The combination of data from multiple imaging systems to obtain multimodal information is of great importance for improving the understanding of structural changes in the eye during a disease. The purpose of this project is to observe structures that are not detectable with routinely used systems.
Scleral depression is an important technique used to examine the peripheral retina but often causes patient discomfort. The goal of this study was to compare levels of discomfort during scleral depression with a Schocket scleral depressor and cotton tipped applicator.
This is a prospective cohort study, comparing the functional outcomes and the retinal displacement rates between two techniques for primary rhegmatogenous retinal detachment repair: Pars Plana Vitrectomy (PPV) and Pneumatic Retinopexy (PnR).
