Minimal Differences Between Anti-VEGF Drugs on IOP Over Time
Patients on anti-VEGF therapy may have a small decrease in intraocular pressure (IOP) over time, but with minimal differences between aflibercept, ranibizumab, and bevacizumab, a new large study suggests. Reuters Health Information
For Monitoring Glaucoma, OCT Bests Visual Field Testing
Optical coherence tomography (OCT) is more sensitive than visual field (VF) testing at detecting progression in early glaucoma, new research reports. Reuters Health Information
Interview With Director of Biomaterials Research Innovation Center, Prof. Ali Kadhemhosseini
The fields of tissue engineering, regenerative medicine, and drug delivery are burgeoning due to the development of new technological advancements in engineering, material science, and chemistry. At the confluence of such diverse fields lies the Biomaterials Innovation Research Center. Located in the hub of Boston, in the Brigham and Women’s Hospital, the center is directed […]
Cognitive Decline, Increased Visual-Field Variability in Glaucoma
Cognitive decline is associated with increased visual-field variability over time in patients with glaucoma, suggesting a need to screen and monitor for cognitive dysfunction, according to a new study. Reuters Health Information
Doctors Perform First Robot-Assisted Surgery Inside Eye
A team of surgeons has successfully performed what they say is the world’s first robotic-assisted surgery inside the human eye.

Purdue Developing Self-Cleaning, Magnet Powered Implantable Catheters
Implantable drainage catheters, such as those used to drain cerebrospinal fluid in patients with hydrocephalus, tend to eventually get plugged up with fibrin, bacterial biofilms, blood, or as a result of the body’s immune system attacking them. New surgeries are often required to replace the devices, potentially causing serious complications and costing a lot of […]
Diabetic Macular Edema Rates Increase After Cataract Surgery
The rates of treatment-requiring diabetic macular edema (DME) increase sharply in the year after cataract surgery, according to new findings from the U.K. Reuters Health Information
Screen Eye Clinic Patients for Depression: Study
Eye clinic patients with low vision or blindness, and those who smoke or have diabetes, are at increased risk of being depressed and should be screened for depression, new research reports. Reuters Health Information
Laser-Induced Graphene Showing Promise as Implant Material
Scientists from Rice University and Israel’s Ben-Gurion University of the Negev have identified that laser-induced graphene, a material designed on purpose to have imperfections, both prevents the buildup of organic materials on its surface and can be used to electrically kill bacteria that comes in contact with it. While typical graphene is simply a flat sheet […]

Abbott received Euroepan CE Mark of approval for its TactiCath Contact Force Ablation Catheter, Sensor Enabled for treatment of atrial fibrillation. The device features a pressure sensor that provides feedback on the contact force applied to cardiac tissue, helping to make sure that an appropriate amount of ablation takes place. Coupled with the company’s EnSite Precision […]
R.I.P. – Scanadu Scout – 01/30/15-05/15/17
The infamous, but greatly-hyped Scanadu Scout prematurely departed this Earth shortly after midnight on May 15 in the year of our Lord 2017, to join the likes of Google Glass, Amazon Fire Phone, and the Nintendo Virtual Boy in Gadget Flop Heaven. It was just over 27 months old. The Scanadu Scout was conceived in […]
Biological Supercapacitors to Power Medical Implants
Patients with cardiac pacemakers and other implantable electronic medical devices end up requiring re-implantations when the batteries run out. While we’ve seen the slow but steady progress of battery technology, there’s a great deal of opportunity for harvesting electrical energy from the body and using it to power implants. To this end, scientists at the […]
Bevacizumab Effective for Macular Edema Due to Central Retinal Vein Occlusion
