Voretigene neparvovec-rzyl (Luxturna, Spark Therapeutics) was approved in December 2017 for the treatment of patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy. Clinical trial results and patient selection issues for this gene therapy are discussed.

Maurice B. Landers III, MD, presents an argument that in an era when pharmacological therapy has become the mainstay for the treatment of diabetic macular edema (DME), pars plana vitrectomy (PPV) deserves consideration as a reasonable alternative for early DME in appropriate patients.
Results of the prospective TREX-DME study provide an evidence base for using a treat-and-extend protocol for administering anti-VEGF injections for eyes with diabetic macular edema.
Suprachoroidal triamcinolone acetonide (CLS-TA, Clearside Biomedical) injection resulted in visual and anatomic improvements in eyes with diabetic macular edema, particularly in those that were treatment-naïve. Multiple injections of the investigational treatment were well-tolerated and associated with a low incidence of IOP elevation.
The presence of vitreomacular adhesion (VMA) is associated with poorer, short-term anatomic, and functional outcomes in eyes with diabetic macular edema (DME) receiving anti-VEGF therapy, according to Márcio B. Nehemy, MD, PhD.
The efficacy of intravitreal bevacizumab (Avastin, Genentech) for improving vision in patients with center-involving diabetic macular edema (DME) has been demonstrated in several clinical trials.
All three anti-vascular endothelial growth factor (anti-VEGF) agents that are commercially available have demonstrated efficacy for the treatment of diabetic macular edema (DME). However, it is clear from the results of clinical trials that outcomes with bevacizumab are not as good as those obtained using ranibizumab or aflibercept, according to Jean-François Korobelnik, MD.
Analyses of data collected in the RISE/RIDE and VIVID/VISTA clinical trials provide important messages about the efficacy and safety of ranibizumab (Lucentis, Genentech) and aflibercept (Eylea, Regeneron) for treatment of diabetic macular edema (DME).
