Objective: The aim of the present study was to compare the performance of positron emission tomography (PET) component of PET/computed tomography (CT) with new emerging PET/magnetic resonance (MR) of the same vendor.
Methods: According to National Electrical Manufacturers Association NU2-07, five separate experimental tests were performed to evaluate the performance of PET scanner of General Electric GE company; SIGNATM model PET/MR and GE Discovery 710 model PET/CT. The main investigated aspects were spatial resolution, sensitivity, scatter fraction, count rate performance, image quality, count loss and random events correction accuracy.
Purpose: The purpose of this study was to document clinical findings and management of a patient with bilateral globe luxation and optic nerve transection.
Materials And Methods: A 25-year-old female patient was admitted to the emergency department with bilateral traumatic globe luxation following a motor vehicle accident.
Results: Visual acuity testing showed no light perception.
Purpose: To evaluate the effects of a mid-viscosity mucomimetic lubricant eye drop containing hydroxypropyl guar (HPG) as a gelling agent on computerized perimetry FASTPAC test results of primary open-angle glaucoma (POAG) patients with trachomatous dry eye.
Methods: Both eyes of 33 patients with bilateral POAG and trachomatous dry eye were included in the study. They were treated with the same antiglaucomatous eye drop and underwent computerized perimetry.
Purpose: The purpose of this study was to evaluate the efficacy of topical cyclosporine A (CsA) treatment in patients with severe trachomatous dry eye.
Methods: Sixty-four severe trachomatous dry eye patients who had undergone Schirmer testing with topical anaesthetic measured 5 mm or less and a tear film break-up time (TFBUT) of 5 s or less were included in the study. Thirty-two patients were treated with CsA 0.
Purpose: The purpose of the present study was to evaluate the effect of topical cyclosporine A (CsA) treatment on corneal thickness (CT) in patients with trachomatous dry eye.
Methods: Sixty-four patients with trachomatous dry eye with a Schirmer test showing 5 mm or less and a tear film break-up time (TFBUT) of five seconds or less were included. Thirty-two patients were treated with twice daily application of CsA (0.
