We previously reported on the elevated intravitreal activities of tryptase and chymase in association with idiopathic epiretinal membrane (ERM) and idiopathic macular hole (MH). In this present study. we investigated the potential intraocular production of these serine proteases. and measured and compared tryptase and chymase activities in the vitreous body and serum in ERM. https://pipingrockers.shop/product-category/avocado/
