To the Editor:Anterior chamber(AC)paracentesis is a commonly performed procedure to lower intraocular pressure(IOP),and to sample aqueous humor(AH)for clinical and research purposes.As suggested by an international collaboration team,an immediately performed AC paracentesis before an intravitreal injection can also prevent post-injection IOP spike.[1]While IOP could immediately be reduced by AC paracentesis,the procedure of obtaining an AH sample(liquid biopsy)is more complicated.Several methods have been developed to facilitate AH collection and transfer,[2-7]among which a vacuum-based AH collector(SnovoDAHC I-50,Sightnovo Medical Technology Co.,Beijing,China)has better performance than the commonly used insulin syringe in accurate sampling of about 50μL AH in rabbits by one hand.[7]The current clinical trial aimed to evaluate the performance and safety of this product in human subjects.
