AIM:To evaluate the predictive value of superficial retinal capillary plexus(SRCP)and radial peripapillary capillary(RPC)for visual field recovery after optic cross decompression and compare them with peripapillary nerve fiber layer(pRNFL)and ganglion cell complex(GCC).METHODS:This prospective longitudinal observational study included patients with chiasmal compression due to sellar region mass scheduled for decompressive *** estimating equations were used to compare retinal vessel density and retinal layer thickness preand post-operatively and with healthy *** regression models were used to assess the relationship between preoperative GCC,pRNFL,SRCP,and RPC parameters and visual field recovery after ***:The study included 43 eyes of 24 patients and 48 eyes of 24 healthy *** RPC and SRCP vessel density and pRNFL and GCC thickness were lower than healthy controls and higher than postoperative *** best predictive GCC and pRNFL models were based on the superior GCC[area under the curve(AUC)=0.866]and the tempo-inferior pRNFL(AUC=0.824),and the best predictive SRCP and RPC models were based on the nasal SRCP(AUC=0.718)and tempo-inferior RPC(AUC=0.825).There was no statistical difference in the predictive value of the superior GCC,tempo-inferior pRNFL,and tempo-inferior RPC(all P>0.05).CONCLUSION:Compression of the optic chiasm by tumors in the saddle area can reduce retinal thickness and blood *** reduction persists despite the recovery of the visual field after decompression ***,pRNFL,and RPC can be used as sensitive predictors of visual field recovery after decompression surgery.

The metabolic process of chiral drugs plays a significant role in clinics and in research on drugs. Here, we experimentally demonstrate by all-optical means that the chiral molecules can be quickly discriminated and monitored with the ultrahigh- order modes excited in a metal cladding optofluidic chip, achieving over 5 times sensitivity with a low-dosage sample. We show that the varying concentration of the chiral drugs can be monitored both in cell and animal experiments, presenting a significant difference between chiral enantiomers at the optimal function time and the effect of the reaction. To our knowledge, this approach provides a new way to achieve important chiral discrimination for the pharmacokinetics and the pharmacodynamics and may present opportunities in indicating the health status of humans.
