Resistance to fluoroquinolones impacts retina casesAntibiotic resistance against fluoroquinolones is increasing, and that may adversely impact patients with retinal disorders. The introduction of intravitreal injections (IVT) to treat retinal diseases has increased from about 1 million in 2007 to an expected 6 million in 2016 (up from only 4,000 in 2001).
SHRM characteristics impact visual acuity in wet AMDSubretinal hyperreflective material (SHRM) is a morphologic component seen on optical coherence tomography (OCT) images as hyperreflective material that is external to the retina and internal to the retinal pigment epithelium (RPE), said Jaya B. Kumar, MD.
Priming syringe before injection associated with lower frequency of silicone oil dropletsAnother adverse effect associated with the compounding process of bevacizumab (Avastin, Genentech)—i.e., the presence of silicone oil droplets in the vitreous cavity—has surfaced within the past year and seems to be related to the preloading of the drug in insulin syringes.
Dye from açai fruit safe, effective for use during chromovitrectomy
Dye from açai fruit safe, effective for use during chromovitrectomyA dye made from the açai fruit (Euterpe oleracea) is safe for use in human eyes and effective for identifying the posterior hyaloid and internal limiting membrane (ILM) during vitreoretinal surgery, according to phase I preliminary study results.
Paracentral retinotomy facilitates closure of large, resistant macular holeRecognition of this problem resulted in an innovative approach for closing persistent macular holes after the primary surgery has failed by creating a separate paracentral retinotomy in the nasal macula. Michael S. Tsipursky, MD, described the rationale for trying this treatment approach. “
B+L next-generation surgical platform features advanced retina capabilities
Multisensory art the focus of exhibition at London's Science MuseumA three-day exhibition that shows how people with visual impairments can appreciate a wide range of art forms was unveiled at the Science Museum on 8th August 2017.
Laser retains limited role for management of RVO-related MEIn the current era where pharmacologic therapy is the preferred treatment for macular edema secondary to retinal vein occlusion (RVO), there is still a role for laser, according to Francesco Bandello, MD.
Anti-angiogenic agent, platform planned for human trialFindings from preclinical studies show that a novel intravitreal depot of an anti-angiogenic drug releases the medication over a period of at least 6 months, is well-tolerated, and prevents VEGF-induced retinal vascular leakage.
Scleral buckle technique using PPV, laser photocoagulation
Scleral buckle technique using PPV, laser photocoagulationScleral buckles and vitrectomy are the two main procedures used today to treat retinal detachments, with many surgeons performing a combination of the two.
