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.

Wide-field imaging has become an integral tool in the diagnosis and management of patients with retinal disease.

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.

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.

A retinal exam system improves access for patients with diabetes to detect eye disease early and refers them to an eye-care specialist for further evaluation and treatment.

Though much has been learned about non-arteritic ischemic neuropathy since the earliest studies, no effective treatment is currently available. An update on research progress is highlighted.

Macular degeneration and diabetes appear to be playing smaller roles in sight impairment in England and Wales, according to the National Institutes for Health Research (NIHR).

Experience with en face OCT shows its value for following disease progression in wet and dry age-related macular degeneration and in diseases that disrupt the inner segment/outer segment/ellipsoid zone.

Take-home: Evidence is accumulating documenting that intraoperative OCT improves surgeon decision-making and outcomes of patients undergoing vitreoretinal procedures.

Ultra-widefield retinal imaging is a user- and patient-friendly technique that is showing promise for improving clinical care.
