DRCR.Net Aflibercept vs. Bevacizumab + Deferred Aflibercept for the Treatment of CI-DME

Both aflibercept and bevacizumab have been shown to improve vision in eyes with DME. In eyes with DME and at least moderate vision loss, both aflibercept and bevacizumab were also shown to be successful in many eyes. However, aflibercept was shown to be more effective at improving vision, on average, at 1 year and at 2 years. Due to the large cost difference between the two drugs, many clinicians and patients are choosing to initiate treatment with bevacizumab and then switch to aflibercept depending on the eye's response to bevacizumab treatment. However, there is no scientific evidence that this treatment strategy is as effective at improving vision as initiating treatment with aflibercept. Patients and clinicians do not know if this approach ultimately has deleterious effects on visual acuity. If starting with aflibercept is not better than starting with bevacizumab and switching to aflibercept if needed, the potential cost savings to future patients and the health care system would be substantial. However, if starting with aflibercept is better, then patients, clinicians, and health care providers can make informed decisions for how to best treat patients with DME and at least moderate vision loss. Study Objectives To compare the efficacy of intravitreous aflibercept with intravitreous bevacizumab + deferred aflibercept if needed in eyes with CI DME and moderate vision loss

Assessment of EyeCheckup as an Automated Diabetic Retinopathy Screening Tool

The duration of diabetes is directly related to eye complications. Diabetic retinopathy affects 80 percent of those who have had diabetes for 20 years or more. At least 90% of new cases can be reduced with proper treatment and monitoring of the eyes. The longer a person has diabetes, the more likely it is to develop diabetic retinopathy. Each year in the United States, diabetic retinopathy accounts for 12% of all new cases of blindness. It is also the leading cause of blindness in people between the ages of 20 and 64. The most important complication of diabetes leading to vision loss is diabetic retinopathy. Depending on this, macular edema, bleeding into the retina and vitreous,neovascular glaucoma can cause blindness. Diabetic retinopathy (DR) is a leading cause of vision-loss globally. Of an estimated 285 million people with diabetes mellitus worldwide, approximately one third have signs of DR and of these, a further one third of DR is vision-threatening DR, including diabetic macular edema (DME). Diabetic retinopathy is a retinal disease that can often be stopped with early diagnosis, but if neglected, it can lead to severe vision loss, including permanent blindness. Diabetes has high morbidity and there are millions of people who should be screened for diabetic retinopathy (DR). Annual eye screening is recommended for all diabetic patients since vision loss can be prevented if DR is diagnosed in its early stages. Currently, the number of clinical personnel trained for DR screening is less than that needed to screen a growing diabetic population. Therefore, the automatic DR screening system will be able to screen more diabetic patients and diagnose them early. EyeCheckup is an automated retinal screening device designed automatically analyze color fundus photographs of diabetic patients to identify patients with referable or vision threatening DR. This study is designed to assess the safety and efficacy of EyeCheckup. The study is a single center study to determine the sensitivity and specificity of EyeCheckup to diabetic retinopathy. EyeCheckup is an automated software device that is designed to analyze ocular fundus digital color photographs taken in frontline primary care settings in order to quickly screen for diabetic retinopathy (DR).

Validation Study of RETINA-AI Galaxy™, an Automated Diabetic Retinopathy Screening Device

Diabetes affects approximately 35 million Americans, each of whom needs at least one retinal exam per year. However, majority do not get their eye exam due to multiple prohibitive factors such as cost, transportation, difficulty of taking time off from work, and inconvenience, amongst others. The standard of care in diabetes requires at least an annual eye exam to detect onset of diabetic retinopathy and to treat when indicated. This is important as diabetes is the most common cause of visual impairment and blindness in working age adults in the United States. There are too few trained professionals to diagnose diabetic retinopathy, this prompted the development of RETINA-AI Galaxy an automated software as a medical device which screens for diabetic retinopathy in the primary care setting. This observational study is designed to validate the safety and efficacy of the device.

Aflibercept in Recurrent or Persistent CNV

Age-related macular degeneration (AMD) and diabetic retinopathy are among the most common disorders causing visual disability in elderly people. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process. The purpose of the study is to evaluate the effect of switching from ranibizumab therapy to the current routine therapy using aflibercept in eyes with treatment naive, recurrent or persistent nAMD, treatment naive diabetic retinopathy and pretreated diabetic retinopathy. 20 patients with recurrent or persistent nAMD, previously treated with intravitreal ranibizumab for up to one year will be included in this trial. Patients will be examined in monthly intervals over 12 months follow-up. Examinations carried out will include: Best-corrected visual acuity (BCVA) using ETDRS charts at 4m distance, Reading Performance (RP), Standard ophthalmic examinations (SOE incl. funduscopy and applanation tonometry), Optical coherence tomography (OCT), Autofluorescence fundus image (AF) & red-free autofluorescence fundus image (RF), Color fundus photography (CFP), Fluorescein angiography and indocyaningreen angiography (FLA/ICG), Microperimetry (MP), as well as Non-invasive OCT based optical angiography (AngioVue).

Prophylactic Effect of Conbercept Intravitreal Injection at the Conclusion of Cataract Surgery for Diabetic Macular Edema

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.

Diabetic Macular Edema - Obstructive Sleep Apnea Relationship Study

The purpose of this study is to evaluate the relationship between DME and obstructive sleep apnea (OSA). OSA impacts millions of North Americans, many of whom are undiagnosed. The investigators aim to evaluate if a relationship exists between the two diseases, whether or not the severity of OSA impacts the severity of DME, and whether treating OSA results in better treatment outcomes for DME. The study will involve the standard of care provided for both DME (involving anti-VEGF injections) and OSA (involving continuous positive airway pressure [CPAP] machine).Approximately 150 subjects are expected to be enrolled in this study. In summary: Question 1: Is there a correlation between DME and OSA? Question 2: Is there a relationship between the severity of DME (CRT and vision) and OSA (AHI index)? Question 3: Does treating OSA result in improving DME metrics, and does it neutralize the outcomes at 1 year compared to OSA negatives.
