Researchers have identified a group of proteins that may play critical roles in causing blood vessel leakage in the eyes of people with diabetic retinopathy. CA-1, an enzyme normally found in red blood cells, was found to increase blood vessel leakage and swelling in both the eyes and brain.
A Joslin Diabetes Center-led team identified a group of proteins that may play critical roles in causing blood vessel leakage in the eyes of people with diabetic retinopathy. One of these molecules causes retinal blood vessel leakage, contributing to swelling and vision loss.
This special issue of the Journal of Rehabilitation Research investigates innovative approaches to vision rehabilitation, including surgical excision of abnormal blood vessels and resurfacing with patient-derived retinal pigment epithelial cells. Teleretinal imaging is also explored as a tool for screening patients with diabetes for di...
A six-year study found high progression rates of diabetic retinopathy in African Americans with type 1 diabetes, linked to poor glycemic control and high blood pressure. The study highlights the need for improved medical care and regular eye exams to detect vision-threatening diabetic retinopathy.
A new clinical trial has shown that the oral treatment RBX may reduce the risk of moderate vision loss caused by macular edema in patients with type 1 or type 2 diabetes. The study, led by Joslin Diabetes Center, evaluated the safety and effect of RBX on retinopathy progression and visual loss.
Researchers discovered that diabetic retinopathy occurs in people with pre-diabetes, suggesting eye changes may begin earlier than previously thought. Regular eye exams and good blood sugar control are recommended to prevent vision loss.
A recent study published in Diabetes journal found that minocycline limits retinal damage caused by microglia cells in diabetic rats. The antibiotic reduces neuroinflammation and activation of microglia, resulting in less nerve cell death and improved vision outcomes.
Researchers successfully silenced SDF-1's signal in mice with simulated retinopathy, effectively halting the growth of new blood vessels. The study could lead to a treatment option using routine injections of an antibody-blocking substance into a patient's eye.
A new technique using spectral imaging allows doctors to detect and chart eye diseases such as diabetic retinopathy and glaucoma with high accuracy. The method uses liquid crystal tuneable filters and cooled digital cameras to take images at specific wavelengths, revealing the oxygenation state of blood vessels in the eye.
A new study by USC researchers reveals high levels of visual impairment and eye disease among Latinos, with nearly one in four participants having diabetes and nearly half showing signs of diabetic retinopathy. The study also found that open-angle glaucoma and ocular hypertension were prevalent among the Latino population.
A comprehensive study found that US Latinos have high rates of diabetic retinopathy, open-angle glaucoma, and cataract, with significant disparities in healthcare access. Researchers emphasize the importance of providing culturally tailored programs to detect and manage eye diseases in this population.
The NIST-developed standards provide guidelines for capturing, storing, and interpreting images of the eye to aid in diagnosing diabetic retinopathy. This approach allows healthcare professionals flexibility in choosing equipment, while ensuring quality image capture.
A study by the Eye Diseases Prevalence Research Group found that approximately two-fifths of persons aged 40 and older with DM are affected by diabetic retinopathy, while one in twelve have reached a vision-threatening stage. The prevalence rates were estimated using data from eight population-based eye surveys.
Diabetic retinopathy, a leading eye complication in people with type 1 diabetes, affects nearly 774,000 Americans under age 30. The prevalence is highest among 40-49 year olds and older, driven by aging US population.
Two studies found a strong connection between diabetes, hypertension, and serious eye disease, particularly among black populations. Higher systolic blood pressure and poor diabetes control increase the risk of diabetic retinopathy and related conditions like open-angle glaucoma.
A landmark study conducted by the University of Southern California found that nearly two-thirds of Latino participants with diabetes were not following American Diabetes Association guidelines for vision care, leading to higher rates of diabetic retinopathy, early macular degeneration, and glaucoma among this ethnic group.
A new study from the Liverpool Diabetic Eye Study has proposed optimal screening intervals for diabetic eye disease, based on incidence data. The findings suggest that patients with no baseline retinopathy should be screened every 3 years, while those with background retinopathy can be screened annually.
Researchers seek compounds to inhibit angiogenesis, a common cause of vision loss. A new class of anti-angiogenic molecules has shown promise in pre-clinical studies, with 70% inhibition in 100% of cases.
A study found that people with type 2 diabetes experienced increased oscillatory potentials after dark adaptation, which decreased with oxygen inhalation. The researchers suggest that diabetic patients might benefit from a modified night-time illumination cycle during sleep to reduce oxygen consumption in the retina.
The DIRECT programme aims to establish whether candesartan cilexetil can prevent and treat diabetic retinopathy. The trial will investigate the effect of RAS blockade on diabetic patients with and without retinopathy.
The National Heart, Lung, and Blood Institute recommends a more aggressive approach to treating high blood pressure in patients with type 2 diabetes. This is based on studies showing significant reductions in diabetes-related strokes, small blood vessel damage, and deaths when blood pressure is brought under control.
A new telehealth technology called I-SITE is being used to fight a growing epidemic of diabetic blindness in First Nation Canadian communities. The system has successfully diagnosed and treated diabetic retinopathy, saving eyesight in patients who would otherwise have gone blind.
Researchers suggest that a significant majority of people with type 2 diabetes derive little additional benefit from annual eye screening. Instead, every other year or even every third year screening is nearly as beneficial and more cost-effective. This finding could lead to a shift in recommendations for optimal screening intervals.
African Americans with diabetes who receive health education messages are more likely to seek an eye exam, increasing the rates of dilated eye exams. Early detection and treatment can prevent vision loss in people with diabetes, with about 90% preserving their vision.
