Purpose: To evaluate the histopathological changes of the cornea in rabbit corneas after accelerated collagen cross-linking. Methods: Right eyes of 7 adult New Zealand albino rabbits weighing 1.5 to 2.0 kg were studied. Right eyes of all animals were in the treatment group and left eyes were in the control group. The epithelium of all right eyes was removed and was crossed-linked with riboflavi...
Background and Objective: Keratoconus is a disorder in cornea characterized by constant thinning and prominence that can result in vision defect. Due to ultrasonic changes in the corneal structure caused by keratoconus disease, its rigidity and biomechanical properties are subject to some changes. In this regard, the present study was conducted to determine the correlation of biomechanical feat...
Introduction: Intravitreal Avastin (bevacizumab) injection is reportedly accompanied by ocular and systemic side-effects. Our enquiry assesses whether there are any differences between intraocular pressure (IOP) in baseline and on the day after injection in patients treated for retinal disease. Methods: In this experimental study, 82 eyes with retinal diseases that had indication for anti-VEGF...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: to investigate the reasons for p ostvitrectomy diabetic vitreous hemorrhage (pdvh), and to analyze the time of pdvh onset, the treatment of pdvh, the visual outcome of the treatment, and factors that affect visual acuity after treatment. materials and methods: overall, 292 eyes from 236 patients with proliferat...
Background and Aim: Although combined "Chemotherapy and Focal therapy" is very efficient in the treatment of the low grade forms of Retinoblastoma (Rb), more effective therapeutic measures are required to control the spread of the disease into vitreous and subretinal areas.This study was conducted with the aim of evaluating the effectiveness of chemotherapy combined with perioricular inject...
Conjunctival microbial flora is the main source of organisms causing postoperative endophthalmitis. Therefore this study has been performed to evaluate this flora in patients undergoing intraocular surgery. This nonselective study was done prospectively on 251 eyes of 211 patients who underwent intraocular surgery during 1378-1379 (1999-2000 AD) in Hazrat Rasul-e Akram hospital, Tehran, Iran...
Objectives: The authors of this paper hypothesized that vibration stimulation applied by a vibratory orthosis improves balance in patients with Parkinson’s disease (PD). In this study we evaluate this hypothesis. Methods & Materials: Fourteen PD patients (12 male and 2 female) with mean age of 59.9±9.1 (±SD) years were participated in this cross- sectional study. Using Biodex balance system,...
Objectives: Researchers have focused their attention on balance in the elderly because there is a significant correlation between balance and fall. Therefore, it is very important to identify the factors that can affect elderly balance. The aim of this study was to investigate relation between sustained attention and balance in elderly. Methods: This cross sectional study was conducted in 20...
Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...
