Filter by:Background: One of the most difficult refractory glaucomas in treatment is the neovascular type and its association with dense cataract add to this difficulty. This study aimed to provide results of triple surgical treatment of such conditions. Methods: A total of 12 eyes of 12 patients with dense cataractus NVG patients were included in this study. The patients mean age was 57.25 ± 5.9 years. The mean pre-operative intraocular pressure (IOP) was 47.25 ± 4.04 mmHg with maximum antiglaucoma therapy. The mean best corrected distant visual acuities (BCDVA) in log MAR was 2.13 ± 0.38. All the patients received intra-vitreal injection of 1.25 mg (0.05 ml) bevacizumab followed by phacoemulsification, pars plana vitrectomy (PPV) including pan-retinal photocoagulation (PRP), and assisted trabeculectomy with Mitomycin c (MMC). Mean IOP and BCDVA changes were the main outcome results of this study.
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
A Phase III, Multinational, Multicenter, Investigator-Masked, Randomized, Active-Controlled Trial, comparing the efficacy and safety of DE-130A with Xalatan® in Patients with Open-Angle Glaucoma or Ocular Hypertension over a 3-Month period, followed by a 12-Month Follow-Up with Open-Label DE-130A Treatment.
Background: Diabetic retinopathy (DR) is one of the most important causes of blindness worldwide, especially in developed countries. In diabetic patients, periodic examination of the back of the eye using a nonmydriatic camera has been widely demonstrated to be an effective system to control and prevent the onset of DR. Convolutional neural networks have been used to detect DR, achieving very high sensitivities and specificities. Hypothesis It is possible to develop algorithms based on artificial intelligence that can demonstrate equal or superior performance and that constitute an alternative to the current screening of RD and other ophthalmic pathologies in diabetic patients. Objectives: - Development of an artificial intelligence system for the detection of signs of retinal pathology and other ophthalmic pathologies in diabetic patients. - Scientific validation of the system to be used as a screening system in primary care. Methods: This project will consist of carrying out two studies simultaneously: 1. Development of an algorithm with artificial intelligence to detect signs of DR, other pathologies of the central retina and glaucoma in patients with diabetes. 2. Carrying out a prospective study that will make it possible to compare the diagnostic capacity of the algorithms with that of the family medicine specialists who read the background images. The reference will be double-blind reading by ophthalmologists who specialize in retina. Cession of the images began at the end of 2018. The development of the AI algorithm is calculated to last about 3 to 4 months. Inclusion of patients in the cohort will start in early 2019 and is expected to last 3 to 4 months. Preliminary results are expected to be published by the end of 2019. The study will allow the development of an algorithm based on AI that can demonstrate an equal or superior performance, and that constitutes a complement or an alternative, to the current screening of DR in diabetic patients
PURPOSE: To study circumferential trabeculotomy for congenital glaucoma using Glaucolight illuminated microcatheter. Setting: Ophthalmology department, Faculty of Medicine, Minia University, 61519, El-Minia, Egypt. DESIGN: Prospective, randomized, consecutive interventional study METHODS: This was a prorospective study of 25 eyes of 25 patients with primary congenital or juvenile glaucoma those underwent circumferential trabeculotomy done with an illuminated microcatheter through a period of 24 months. Patients data of 12 months follow-up were recorded. The primary target was mean intraocular pressure (IOP) study in which unqualified (complete success) was defined as an IOP ≤21 mm Hg and at least a 30% reduction without the use of antiglaucoma drugs and a qualified success when medications were used to reach this aim. The secondary target was studding the corneal diameter (CD) and cup disc ratio (C/D) change.
The general purpose of the study is to evaluate the potential beneficial effects of PEA 600 mg supplementation on RGCs function in subjects with glaucoma by pattern electroretinogram after three months of therapy. Secondary objectives are to assess effects on intraocular pressure (IOP) values, if any; to record visual acuity, visual field, central corneal thickness (CCT), and Optical coherence tomography (OCT) (ganglion cell complex - GCC) changes, if any and to follow quality of life (QL) perception (general vision -GV and general health - GH of national eye instutute visual functioning questionnaire 25 items - NEI VFQ25)
The study is a prospective observational study where participants will be recruited from the Ophthalmology department (Outpatient department, Eye Casualty). Only one research visit will be required. Participants will be asked to fill in a set of questionnaires (Visual Functioning Questionnaire-15(61), Low Luminance Questionnaire(62)) assessing their quality of life and vision and their full medical history will be collected. Then they will have their contrast sensitivity tested under various light conditions. If a recent visual field test is not available, that might be performed as part of the study.
Glaucoma is a group of diseases that damage the eye's optic nerve, result in progressive visual field defect and blindness. The aim of glaucoma management is to reduce IOP, and glaucoma implant surgery is the alternative treatment that can be chosen. The effectiveness of the implant on the end stage glaucoma patients was evaluated by the reduction of intra ocular pressure (IOP) and well formed blebs that were evaluated clinically and by using anterior scanning optical coherence tomography (AS-OCT). The safety of the implant was determined by the regression of the clinical symptoms and there were no severe complications such as implant extrusion. Two patients developed improvement of the visual acuity. This was an unpredictable positive result.
The purpose for the study consists in the assessment of the role of Neurotidine® (citicoline oral solution) on the dopaminergic pathway and particularly its potential implications on psychophysical performance and quality of life. Other objectives are the assessment of the tolerability and safety of Neurotidine®.
This is an open-label trial of 20 study participants with glaucoma or ocular hypertension. Participants with qualifying study eye(s) after screening and baseline evaluations will receive the Balance Goggles System. After a baseline evaluation (prior to negative pressure application through the BGS), study eyes will be treated for one hour in the clinic and be evaluated again. They will then use the BGS for the next 3-6 weeks and be evaluated again. The goal is to determine whether the intraocular pressure (IOP)-lowering effects of BGS is accompanied by changes in retinal thickness measured by optical coherence tomography (OCT), retinal vascular density measured by OCT-angiography, or retinal fluorescence measured by a fundus camera.
