Statement of the BVA, the DOG, and the RG on treatment of choroidal neovascularization in diseases other than neovascular age-related macular degeneration; Stellungnahme des BVA, der DOG und der RG zur Therapie chorioidaler Neovaskularisationen bei anderen Erkrankungen als der neovaskul?ren altersabh?ngigen Makuladegeneration (Englische Version);
摘要： Choroidal neovascularizations (CNV) occur not only in age-related macular degeneration (AMD), but also in numerous other macular and retinal disorders of varying etiology and, if left untreated, can cause irreversible visual loss. The diagnosis of CNV as well as the indication for treatment should be made in the same way as in neovascular AMD: On initial diagnosis: best-corrected visual acuity, fundus examination, optical coherence tomography (OCT), and fluorescein angiography. At follow-up: best-correct visual acuity, fundus examination, OCT, and, depending on findings, fluorescein angiography. Active CNV should be treated with intravitreal operative medication (IVOM) using vascular endothelial growth factor (VEGF) inhibitors if patients have visual acuity of at least 0.05 or if there is sufficient reason to assume that visual acuity could increase to over 0.05 under treatment. Underlying disorders can include, e.g., high myopia, angioid streaks, central serous chorioretinopathy, active and inactive uveitis of varying etiology, including retinochoroiditis, chorioretinitis, and choroiditis, eye injuries, retinal dystrophies, e.g., best disease and pattern dystrophies, idiopathic CNV, subretinal masses (osteomas, hamartomas, nevi). If CNV is not present as a complication in the above-mentioned disorders, IVOM with VEGF inhibitors should not be performed. Ranibizumab and aflibercept are approved in Germany for the treatment of CNV secondary to pathologic myopia. Ranibizumab has been approved in Germany since 12/2016 for the treatment of CNV in disorders other than neovascular AMD and pathologic myopia irrespective of the underlying disease. The other VEGF inhibitors, aflibercept and bevacizumab, can be used off-label. Due to its overall significantly poorer treatment results, photodynamic therapy (PDT) should only be used in exceptional cases and extrafoveal localization. After one initial intravitreal administration of VEGF inhibitors, further CNV activity should be monitored monthly for the first 6 months (see point 2). In the case of persisting or recurrent activity, repeated IVOM should be performed. Depending on disease course, the follow-up interval might be extended 6 months after the last IVOM. In individual justified cases (e.g., patients requiring frequent re-injections), a different treatment regimen (e.g., treat and extend) can be considered in the further course. If visual acuity drops below 0.05 on anti-VEGF treatment, or no further positive treatment outcome is expected (e.g., in the presence of atrophy and/or fibrosis), treatment should be discontinued, unless there is a clear possibility that visual acuity could increase again to over 0.05 under treatment. If no improvement is seen under therapy with a certain VEGF inhibitor, or if deterioration occurs, one can consider switching to an alternative VEGF inhibitor.

[Laser Institute of America ILSC? 2019: Proceedings of the International Laser Safety Conference - South Kissimmee, Florida, USA (March 18–21, 2019)] International Laser Safety Conference - Reducing hazards of consumer laser pointer misuse
摘要： This paper begins with a review of significant laser pointer news since ILSC 2017. These include new laws in the U.K., Canada and Switzerland; an MIT-developed laser pointer detection system, the SAE-published ARP6378 with pilot mitigation recommendations, a review of 111 laser pointer eye injuries worldwide, the status of FDA’s 2016 proposal to allow only red laser pointers, and the new LaserIncidents.com website that lists known databases that compile laser incidents and accidents. The paper then looks at methods for reducing the number and severity of laser pointer incidents. For example, Australia and New Zealand have laws severely restricting ownership of laser pointers over 1 mW. In Australia, aircraft incidents increased significantly after the 2008 ban and currently are roughly equal to U.S. incidents on a per capita basis. In New Zealand, aircraft incidents increased after a ban went into effect in 2014. The ARP6378 document cites pilots as the last line of defense. Pilot education, training and protective eyewear/windscreens are discussed in the document. Changes in labeling are suggested. The usefulness of prosecuting laser offenders is discussed. A summary is given of a Jan. 2019 symposium in Tokyo, seeking new laws and ideas for reducing aircraft incidents, consumer eye injuries, and injuries from laser cosmetic devices. Finally, suggested directions for future research are given.
