Filter by:Characterization of Retinal vascular disease in eyes with mild to moderate NPDR in Diabetes type 2, using novel non-invasive Imaging methods, in a longitudinal, prospective and interventional clinical Study with 2 years of duration (CORDIS).
Purpose: To evaluate the clinical efficiency, safety and painfulness of retinal laser photocoagulation employing a pattern scanning laser system Pascal given in a single-session versus conventional laser multiple-session treatment of the same patient with diabetic retinopathy. Methods: The cohort included 60 eyes in 30 patients treated at the Ophthalmology Clinic, Faculty Hospital Ostrava, from 2008 to 2013. Panretinal laser coagulation was performed on one eye using the multispot panretinal photocoagulation given in a single-session system Pascal (SSP) (OptiMedica, Santa Clara, California). On the other eye laser treatment was carried out by the classic conventional multiple-session method (MSM).
This study is conducted to evaluate the safety of a single intravitreal injection of THR-687.
Subjects receiving 16% C3F8 gas tamponade during vitrectomy will have better visual acuity and similar postoperative complications to subjects who receive silicone oil tamponade during vitrectomy.
Subjects undergoing ILM peeling during vitrectomy will have better visual acuity and lower rates of DME to control subjects
Treatment-naïve subjects with center-involved diabetic macular edema undergoing pars plana vitrectomy with internal limiting membrane peeling will have similar visual outcomes but better anatomical outcomes compared to subjects undergoing intravitreal bevacizumab monotherapy at one year.
Diabetes mellitus is a leading cause of death and disability. Diabetic Retinopathy (DR) is an eye disease that affects the eyesight of about 21.3% persons with diabetes in Bangladesh in a way that is irreversible because of the nature of the disease. According to International Diabetes Federation Diabetes Atlas (5th Edition), in 2011 there were approximately 8.4 million people in the age bracket 20-79 suffering from diabetes in Bangladesh, and this number is projected to double to 16.8 million by 2030. Based on these statistics, and also according to a nationally published report, the number of persons with DR is estimated to be about 1.8 million in Bangladesh. Taking measures to delay vision loss in persons with diabetes is more cost-effective than its treatment. Timely and effective referral of DR cases to an Ophthalmologist is very important in the prevention of this disease. The objective of this study is to identify reasons of DR referral procedure compliance and non-compliance among registered persons with diabetes in a diabetic clinic and recommend effective strategies to enhance the referral system. The first phase of study is cross-sectional. Second phase of study is a Randomized Controlled Trial (intervention group to receive home-based health education and control group to receive standard care). It is expected that the number of registered persons with diabetes of Barishal DAB hospital who were referred to an Eye Consultant at a tertiary hospital from September 2017 - August 2018 will be N=300. All 300 participants will be eligible for inclusion in the first phase of the study. This group (est. N=300) will be categorized into compliant (est. N=120) and non-compliant participants (est. N=180). Both groups will be interviewed to understand motivation factors for compliance and de-motivation factors for non-compliance. In the second phase of the study, the non-compliant group will be categorized further into intervention and control groups following Randomization. The intervention group will receive relevant health education messages on Diabetic Retinopathy and information about the days and times when eye care services are provided at the tertiary hospital (i.e. service availability information). They will be provided with telephonic reminders at Days 7, 30 and 90 after the health education. Then, after a gap of one month from the last telephonic reminder, both control and intervention groups will be interviewed again. In this way this study will conclude whether the health education intervention is an effective way of improving compliance rate of referred DR persons. All questionnaires will be pre-tested in the study location. All participants will have to sign a detailed Bengali informed consent form. SPSS software will be used for data entry and analysis. Multiple Logistic Regression, along with other tests, will be used to identify variables that significantly influence successful referrals.
To assess the safety and efficacy of two subthreshold parameters (5% and 15% duty cycle (DC)) compared to standard ETDRS (early treatment of diabetic retinopathy study) continuous wave (CW) laser
The PRIME trial will assess the safety of 2 mg intravitreal aflibercept injections (IAI) to achieve and maintain DRSS improvements (2 or more steps) in patients with a baseline DRSS level of 47A to 71A inclusive through 104 weeks as determined by reading center determined DRSS gradings on OPTOS fundus photos and leakage index on OPTOS WF-FA.
Diabetic retinopathy(DR) is one of the most common and serious microvascular complications of diabetes,which is the primary cause of vision loss of diabetic patients. The risk of blindness is 25 times that of healthy people.Fundus fluorescein angiography (FFA) is the gold standard for diagnosing the stage of diabetic retinopathy.However,FFA is an invasive examination which requires the patient to be in good physical condition and is not suitable for large-scale screening.Therefore, it is important to build up an evaluation system for early diagnosis of DR,which is more convenient, safer, and non-invasive.Firstly, this study will retrospectively analyze the FFA images of DR to find the earliest and most frequently occurring fundus quadrant.Secondly,based on the retrospective analysis results, a prospective comparative study will be conducted,which combines the fundus photography with optical coherence tomography angiography(angio-OCT) and physical indicators to find out whether it has consistency, sensitivity and specificity with FFA in diagnosing the stage of DR in order to build up a more effective,safer and faster evaluation system and clinical application for DR.
