Optical Coherence Tomography Findings in Parkinson's and Alzheimer's Disease -Retinal Changes in Neurodegenerative Disease.

Introduction: To investigate retinal nerve fiber layer (RNFL), macular, foveal and parafoveal thickness in patient with early stage Parkinson's (PD) and Alzheimer's disease (AD) by optical coherence tomography (OCT) and to compare results with healthy control group and between both disease.

Methods: Participants with AD dementia (n: 15) and PD (n: 15), besides 15 age-sex matched controls were enrolled in the study and received OCT assessments. Clinical disability grade in PD was determined by the Unified Parkinson's Disease Rating Scale and Hoehn Yahr (H-Y) Scale was used to determine the stage of PD.

Frequency of left atrial dilatation in ischemic stroke.

Objective: The study aimed to evaluate the frequency of left atrial dilatation in cases of first-ever acute ischemic stroke with or without atrial fibrillation in a cohort of patients hospitalized for ischemic stroke.

Methods: Files of 120 patients admitted to our hospital with the diagnosis of acute ischemic stroke were investigated. All patients had at least one brain imaging.
