Filter by:Verify the reliability of VA measured every week at home, by the patient using a TC, compared to the reliability of VA also measured by the patient using a TC but every 2 month at the hospital, during standard DME follow-up visits
This prospective study aims to validate if NeoRetina, an artificial intelligence algorithm developped by DIAGNOS Inc. and trained to automatically detect the presence of diabetic retinopathy (DR) by the analysis of macula centered eye fundus photographies, can detect this disease and grade its severity.
Diabetic macular edema (DME) is an important cause of central vision impairment among people with diabetic retinopathy (DR), which can have a significant adverse effect on daily activities and quality of life. Diabetic patients with preexisting DME are at increased risk of worsening edema following cataract surgery. Previous studies also reported progression of DR after cataract surgery. Clinically significant DME is now classified into center-involved DME (CI-DME) and non center-involved DME (non-CI DME). Randomized clinical trials have established intravitreal antivascular endothelial growth factor (VEGF) therapy as first-line treatment for visual impairment from CI-DME and studies have addressed the influence of anti-VEGF therapy among patients with DME undergoing cataract surgery. However, for patients with non-CI DME before cataract surgery, whether anti-VEGF therapy is necessary at the end of surgery to prevent CI-DME is still clinically controversial. In order to evaluate the prophylactic effect of Conbercept (a recombinant fusion protein with high affinity to all VEGF isoforms and PIGF) intravitreal injection at the conclusion of cataract surgery for DME in patients with DR, the investigators will prospectively recruit 40 cataract patients with DR and non-CI DME and randomly assign these subjects into the study group (combined cataract surgery and intravitreal Conbercept injection, 20 cases) and the control group (cataract surgery alone, 20 cases). The primary outcomes include mean changes in central retinal thickness (CRT) and in diabetic retinopathy severity score (DRSS). The secondary outcomes include changes in best corrected visual acuity (BCVA), foveal avascular zone (FAZ), retinal vessel density (VD), the aqueous concentrations of VEGF, PIGF, interleukin- (IL-) 2, IL-5, IL-6, and IL-8.
To investigate ranibizumab's benefit on prevention of early postoperative vitreous haemorrhage in PDR-DME patients receiving vitrectomy.
Eyes with diabetic macular edema requiring conbercept treatment will be followed up for one month. Before treatment, one week after treatment and one month after treatment, the eyes will be examined by optical coherence tomography (OCT) and optical coherence tomographic angiography (OCTA). The changes of macular edema will be observed and analyzed by OCT leakage mapping software, and the relationship between the changes of macular edema and visual acuity will be analyzed.
This study will be a retrospective analysis of vitrectomy results in patients suffering from diabetic macular edema.
Diabetic macular edema is one of the major causes of visual impairment in diabetic retinopathy patients especially in the working age group. The problem is likely to increase in the future with statistics showing a growing number of the diabetic population especially in the Middle East . .
To demonstrate the safety and tolerability of suprachoroidal CLS-TA alone or in combination with intravitreal aflibercept in subjects with diabetic macular edema associated with diabetes mellitus.
Diabetic macular edema refers to swelling (fluid accumulation) in the center of the retina. The retina is like the film of a camera and is located in the back of the eye. This condition can develop in diabetics where swelling results from leaking of fluid from the blood vessels of the eye, into the center of the retina, the macula. If left untreated, this can affect central. The current standard treatment for diabetic macular edema includes medications injected directly into the eye (intravitreal injections) and laser eye treatment. The drugs that are injected directly into the eye are known as anti-VEGF agents which help to reduce the leaking. This includes bevacizumab (Avastin®) and ranibizumab (Lucentis®). However, some patients do not respond well to these anti-VEGF treatments and will be given the option of switching to an another newer anti-VEGF medication, called aflibercept (Eylea®) that is approved to treat DME. A recent large study has demonstrated that aflibercept was as efficacious as other anti-VEGF therapies listed above and was even superior in patients with worse vision (Diabetic Retinopathy Clinical Research Network, Wells JA, Glassman AR, et al. Aflibercept, Bevacizumab, or Ranibizumab for Diabetic Macular Edema. N Engl J Med. 2015:150218140025008-150218140025008). The purpose of this study is to determine what factors affect the treatment response to aflibercept (amount of swelling reduction) for patients with diabetic macular edema, who were previously unresponsive to ranibizumab injections.
The purpose of this study is explore if a partnership and screening program put in place between a busy retina practice and their referring diabetes care offices can improve diabetic retinopathy and diabetic macular edema diagnosis, care and overall diabetes control in patients with diabetic eye disease.
