Some laser pointers available for less than €20 exceed the legal limits on their power by as much as 127 fold, according to Australian researchers. They have called on regulators to consider a ban on green laser pointers.

The transcription factor XBP1 appears to have an expanding role in endothelial cell survival and retinal vascular degeneration as it relates to aging and diabetes.

Oxidative stress stemming from a growing accumulation of visual cycle adducts may play an important role in the pathogenesis of AMD, suggest new findings.

Retinal changes might serve as a marker for Parkinson’s disease, an experiment in mice suggests. And the therapy also points to a potential treatment.

Intas Pharmaceuticals of Ahmedabad, India, seems to have overcome the manufacturing problems that led to ocular inflammation in 10% of the patients injected with the first three batches of razumab, a biosimilar for ranibizumab, according to two ophthalmologists who have administered the drug.

As a physician passionate about treating and helping patients with retinal disease, I continuously seek out and study new treatment modalities. It can be a very scary time for patients when faced with retinal conditions, such as macular degeneration, retinal detachments, and diabetic macular edema (DME).

Home monitoring of patients with age-related macular degeneration results in earlier detection of choroidal neovascularization with the ForeseeHome device resulted and increased preservation of vision.

Surgery might not be the go-to option for suprachoroidal hemorrhages and detachments–they may resolve on their own. But when needed, a less invasive procedure can produce a quality outcome.

Spectral-domain optical coherence tomography facilitates detailed evaluation of foveal disorders even in the very earliest disease stages.

Non-invasive photobiomodulation may help dry age-related macular degeneration by causing regression of drusen and improving retinal function with benefits in visual acuity and contrast sensitivity.

J. Michael Jumper, MD, a retina specialist, described how retina treatments relate to glaucoma–not only injections, but also vitrectomy and laser treatments can trigger glaucoma.

A new analysis of an old study suggests that early response to agents that block vascular endothelial growth factor can predict longer-term improvement in visual acuity in patients with DME.

The first clinical trial of lentiviral gene therapy in ophthalmology met its primary objective, demonstrating safety and tolerability of subretinal administration of a lentiviral vector expressing anti-angiogenic proteins in patients with advanced exudative age-related macular degeneration.

Evidence suggests more ophthalmologists should perform aqueous sampling and viral testing in hypertensive anterior uveitis cases.

The first randomized, controlled phase III gene therapy trial that is investigating treatment with adeno-associated viral vector delivery of human RPE65 in patients with RPE65 mutation-associated inherited retinal dystrophies is discussed.

Sonepcizumab alone or in combination with anti-VEGF does not provide any short-term benefit to the visual acuity in patients with wet AMD, who were considered to be subresponders to anti-VEGF therapy. However, a combination of therapies may have different results.

Lesions appear in both outer and inner retinal layers in the early onset of glaucoma, with the most pathological change in neurophysiological processes affecting the photoreceptors cells of the outer layer. Such findings could aid in early diagnosis of the disease.

Clinicians should recognize the symptoms of West Nile virus, Dengue fever, and Chikungunya that are spread by mosquitos and can have ocular manifestations.

Single-spot lasers used in photocoagulation usually deliver about 100 milliseconds of laser energy in a single burn. Although effective, they can cause peripheral visual field loss affecting the patient’s ability to drive.

In DME patients with worse baseline visual acuity, aflibercept and ranibizumab provided more of a quality-of-life improvement-yet aflibercept had an associated higher cost.

The debate over pharmacologic therapy versus laser treatment for diabetic eye disease is back. The players are different–anti-VEGF agents and panretinal laser photocoagulation instead of anti-VEGF agents and macular laser photocoagulation.

Investigators in Israel have discovered a retinitis pigmentosa-causing mutation for which unaffected individuals can be mosaic, followed by autosomal dominant inheritance in successive generations.

Results from TIME-2, a phase IIA study, support further development of combination treatment with subcutaneous injection of the Tie2 activator, AKB-9778 (Aerpio Therapeutics), plus intravitreous (IVT) anti-VEGF injection for diabetic macular edema.

Intravitreous injection with ranibizumab (Lucentis, Genentech) is well-tolerated, safe, and improves the functional and anatomic status in patients with visual impairment due to choroidal neovascularization (CNV) associated with rare diseases, according to findings from 6 months of follow-up in the phase III MINERVA study.

Real-world evidence confirms the benefits of intravitreous ranibizumab (Lucentis, Genentech) for treatment of neovascular age-related macular degeneration (nAMD)-regardless of polypoidal choroidal vasculopathy (PCV) status.

Results from a phase I study of KVD001 (KalVista Pharmaceuticals) for the treatment of central involved diabetic macular edema (CIDME) show that this plasma kallikrein inhibitor was well-tolerated, not associated with any ophthalmic or systemic safety signals, and led to fairly long-lasting improvements in visual acuity (VA) and central retinal thickness (CRT) after a single intravitreous injection.

International thought-leaders in retina education will have a new forum with the inaugural Retina World Congress (RWC), Feb. 23 to 26, 2017, in Fort Lauderdale, FL.

Modern combination antiretroviral therapy (cART) has transformed the AIDS epidemic and the management of cytomegalovirus (CMV) retinitis.
