RESUMEN
Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.

A new triterpenoid saponin, named segetoside B, showing inhibition of luteal cell activity, has been isolated from the seeds of Vaccaria segetalis. On the basis of chemical reactions and spectral analyses, its structure has been established as 28-O-[beta-D-xylopyranosyl-(1 --> 4)-alpha-L-rhamnopyranosyl-(1 --> 2)]-[alpha-L-(5-O-acetyl)arabinofuranosyl-(1 --> 3)]-beta-D-(4-O-acetyl)fucopyranosyl-gypsogenin-3-O-beta-D-galactopyranosyl-(1 --> 2)-beta-D-(6-O-methyl ester)-glucuronopyranoside.
