A new robotic system could perform delicate eye surgery
Retinal vein occlusion (RVO) is a severe disease that occurs when a vein in the light-sensitive layer at the back of the eye (i.e., the retina) becomes blocked, which results in a loss of vision. There are currently a few medical interventions that address RVO, including the periodic injection of medications that block the abnormal growth of blood vessels or of steroids, which reduce swelling and inflammation.

Retina-on-a-chip offers promising perspectives for rare eye diseases
Researchers at the University of Twente and Radboudumc are developing a promising new model to enhance understanding of the human retina. They are developing a retina-on-a-chip, in which the three main layers of the retina will eventually be combined. The first two layers have now been successfully integrated, and work on the third is underway.

Sleeping Without Pillows may Lower Harmful High Internal Eye Pressure in People with Glaucoma
Sleeping without pillows may help lower high internal eye pressure, the build-up of which causes optic nerve damage and glaucoma-the leading cause of irreversible blindness worldwide-in people with the condition, suggests preliminary research, published online in the British Journal of Ophthalmology.

How diabetes affects your eyes
The eye contains a sensitive layer called the retina, the light-sensitive tissue at the back of the eye, which plays a vital role in vision. The blood vessels in the retina can be affected by diabetes, leading to a condition known as diabetic retinopathy. It can develop in anyone with type 1 or type 2 diabetes.

AI-powered mobile retina tracker screens for diabetic eye disease with 99% accuracy
A novel AI-powered retina tracker can analyze retinal images with near-perfect accuracy in under one second, according to a study being presented Monday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. The researchers say the findings offer hope for sight-saving screenings for diabetic retinopathy and other eye diseases that are fast, affordable and accessible worldwide.
