Key PointsQuestionWhat is the efficacy of phacoemulsification combined with goniosynechialysis compared with phacoemulsification without goniosynechialysis in lowering of intraocular pressure after 1 year?
FindingsIn this randomized clinical trial of 78 patients with synechial primary angle-closure disease, lowering of intraocular pressure of approximately 7 to 8 mm Hg was achieved by both phacoemulsification alone and phacoemulsification with goniosynechialysis after 1 year.
MeaningThis randomized clinical trial was unable to show that goniosynechialysis with phacoemulsification provided additional lowering of the intraocular pressure compared with phacoemulsification without goniosynechialysis.

Key PointsQuestionIs bilateral voretigene neparvovec-rzyl cost-effective compared with standard care for treating RPE65-mediated inherited retinal disease in the United States over a lifetime horizon?
FindingsIn this economic analysis of data from 70 patients with genetically confirmed RPE65-mediated inherited retinal disease, voretigene neparvovec-rzyl was associated with lower total costs and higher quality-adjusted life-years compared with standard care. In addition, voretigene neparvovec-rzyl was cost-effective over a lifetime horizon using a threshold of $50 000 to $150 000 per quality-adjusted life-year, assuming that the health states across patients in year 3 subsequently did not change over a lifetime.
MeaningThese findings, with their assumptions and using a lifetime horizon, suggest that bilateral voretigene neparvovec-rzyl is cost-effective given its efficacy and the quality-of-life decrement associated with the natural course of inherited retinal disease.
