The majority of dental trauma involves anterior teeth, especially the maxillary central incisors. A mandibular incisor fracture with or without pulp tissue involvement is considerably less common. Different approaches for treating these fractured teeth have been reported in the literature. The type of treatment rendered depends mainly on the extent of fracture, pulp involvement, radicular fract...

BACKGROUND To evaluate the postoperative results and efficacy of retinectomy in the treatment of severe proliferative vitreoretinopathy (PVR). METHODS The study involved 38 individuals with rhegmatogenous retinal detachment initially diagnosed with PVR grade C3 who had undergone pars plana vitrectomy combined with scleral buckle and silicone oil as a tamponade. A standard three-port pars plan...

Purpose. To report the safety and efficacy of adjustable postoperative position for rhegmatogenous retinal detachment (RRD). Methods. Retrospective review of 536 consecutive RRD eyes that underwent vitrectomy surgery for retina repair from year 2008 to 2014. The retinal breaks were divided into superior, lateral (nasal, temporal, and macular), and inferior locations, according to the clock of b...

BACKGROUND AND OBJECTIVE To compare pneumatic retinopexy (PR) and scleral buckle for the repair of primary rhegmatogenous retinal detachment. PATIENTS AND METHODS Retrospective analysis of 90 patients undergoing surgery for primary rhegmatogenous retinal detachment, with 46 patients undergoing PR compared with 44 patients undergoing scleral buckle procedure (SBP). RESULTS Both groups had si...

BACKGROUND The prolongation of survival of patients with herpesvirus retinitis and AIDS has been associated with a rise in the incidence of retinal detachment. In such cases, however, retinal reattachment may be difficult to achieve, and postoperative visual acuity may be poor despite anatomically successful surgery. METHODS In order to examine factors affecting the visual outcome of surgery,...

Aim: To study the functional and anatomic outcomes of retinectomy of 180° or more in eyes with rhegmatogenous retinal detachment (RD) with advanced proliferative vitreoretinopathy (PVR) Grade D. Materials and methods: A retrospective analysis of 51 eyes that underwent pars-plana vitrectomy (PPV) with 180° or more of retinectomy for RD with PVR Grade D was done. Main outcome measures included re...

PURPOSE To describe the characteristics and surgical outcomes of pediatric rhegmatogenous retinal detachment. METHODS A retrospective study of pediatric patients (15 years old or younger) who had undergone primary surgery for rhegmatogenous retinal detachment was conducted. Patients were divided into five groups according to the predisposing factors: trauma (group 1), myopia (group 2), atopic...

Our purpose is to explore a family of specific dynamical methods that support the contrasting goals of presence and independence in collaborative virtual environments. We pose for ourselves the basic tasks of “tethering” — keeping a collaborator close to a group or leader, and of “reattachment” — returning to a collaborative virtual activity after a period of independent exploration. We first p...

PURPOSE The authors used perfluorocarbon liquid (PFCL) and a wide-angle viewing system (WAVS) to evaluate their efficacy on tractional and combined tractional/rhegmatogenous retinal detachment (RD) secondary to proliferative diabetic retinopathy (PDR). METHODS In a prospective, noncomparative, interventional study, 76 consecutive cases of severe PDR with tractional and combined tractional/rhe...
