The pupil of the eye allows light to reach the retina, and a number of vision disorders are related to irregularities in the iris that surrounds the pupil. People with aniridia, for example, have some or all of the iris missing, exhibiting a large pupil that results in unfocused vision. Now, a collaboration between Imec, […]

Novel Solutions to Maintain Glaucoma Care During COVID-19
In-person visits are fraught with concern, but virtual replacements won’t cut it either. Dr Shuchi Patel looks at some potential alternatives. Medscape Ophthalmology
Origami Surgical Manipulator to Perform Microsurgeries
Robotic surgical assistants, such as the da Vinci systems from Intuitive Surgical, are now routinely used during laparoscopic procedures to improve operative precision, flexibility, and to manipulate multiple tools at once. Such devices can be quite complex inside and so they tend to be quite large, often taking up much of the space of an […]
How Prevalent Are Adverse Effects in LASIK and PRK?
Dr Christopher Rapuano comments on the compelling case for modern laser vision correction techniques made by a recent database analysis. Medscape Ophthalmology
Anticipating the Long-term Ocular Effects of COVID-19
A picture of COVID-19’s acute ocular symptoms is emerging, but the long-term effects are not clear. Dr Brianne Hobbs explains what we know. Medscape Ophthalmology
Macular Edema Treatments Less Effective in the Real World
Anti-VEGF drugs preserved vision in patients treated for diabetic macular edema after 5 years, but not as well as when the patients were part of a clinical trial. Medscape Medical News
AI Could Help Track Response to Anti-VEGF Therapy for Diabetic Macular Edema
Artificial intelligence analysis of imaging data could help monitor treatment response in patients with diabetic macular edema undergoing treatment with anti-VEGF, a new study shows. Reuters Health Information
eSight 4 Vision Assistive Glasses Unveiled
eSight, a company based in Toronto, Canada, is releasing the latest version of its vision-improving electronic glasses for people with poor eyesight and even legal blindness. The eSight 4 sports two 1280×960 screens that display images captured and processed from the forward facing camera on the glasses. It’s indicated for people with all kinds of […]
Cardio Risk Increases With Diabetic Retinopathy Progression
The strong correlation between severity of diabetic retinopathy and cardiovascular events could help ophthalmologists motivate affected patients with type 2 diabetes to see a primary care provider. Medscape Medical News
OCT Angiography a Good Way to Detect Diabetic Retinopathy
Wide-field swept-source optical coherence tomography angiography can detect key features of diabetic retinopathy, in a much less-invasive manner than common alternatives, researchers report. Medscape Medical News
As Ophthalmology Clinics Reopen, New Questions Abound

Curved-Field OCT for Unprecedented View of The Cornea
Optical coherence tomography (OCT) is an imaging technique regularly utilized by ophthalmologists to view multiple layers of the cornea and count the nerves and cells within. It’s important for diagnosing a variety of corneal conditions as well as when preparing for cataract surgery. The problem is that, as anyone who has tinkered with macro photography […]
Ophthalmologists Called to Catch Cancers Earlier
Advances in the management of common eye cancers have highlighted the need for early treatment, experts say. Medscape Medical News
Rubber Bullets, Tear Gas: What Doesn’t Kill Can Still Blind
Use of rubber bullets and tear gas during the recent protests has led to significant eye injuries. Dr Ann Murchison offers guidance on appropriate ocular management in the midst of a pandemic. Wills Eye Hospital
Should We Treat or Observe DME With Good Vision?
Treating all patients with central-involved diabetic macular edema, regardless of their vision quality, may not be a clinically effective strategy. Medscape Ophthalmology
COVID-19 Status Should Influence Noninfectious Uveitis Treatment Decisions
In patients with noninfectious uveitis, the individual’s COVID-19 status should influence decisions regarding immunomodulatory therapy, according to a survey-based study. Reuters Health Information
Nanoparticles for Large Gene Therapy to Cure Common Eye Diseases
Wet age-related macular degeneration and a number of other eye diseases, including congenital conditions, are related to mutated genes that result in blood vessel abnormalities. These can be treated with gene therapy, but delivering genetic material has proven to be difficult when dealing with large gene sequences that are common in retinal conditions. Viruses have […]
Injectable Liquid Prosthesis to Treat Retinal Diseases Developed
Retinal prostheses promise the restoration of vision to people with age-related macular degeneration, retinitis pigmentosa, and other conditions that lead to the loss of functional photoreceptors. A number of technologies are already in existence that mimic the functionality of the retina by stimulating the inner retinal network, but most of these rely on wearable cameras, […]
Artificial Intelligence Passes Macular Degeneration Test
A deep-learning system accurately diagnosed age-related macular degeneration in a real-life population in a prospective clinical trial. Medscape Medical News
AI for Comprehensive Annotation of Retinal Lesions
Researchers at Radboud University Medical Center in The Netherlands have developed a new AI algorithm for detecting diabetic retinopathy and age-related macular degeneration. The algorithm’s iterative approach identifies greater lesions than non-iterative approaches, and boosts specificity by approximately 10%, with diagnostic accuracy of about 80%. The algorithm annotates images to depict which lesions it finds […]
