PPIB and fungal infection of eye: MNs are emerging as a minimally invasive method to enhance ocular drug delivery with no irritation [29]. However, most studies had either used model drugs [44, 45] or drug-like pilocarpine [46]. Only one study was published recently, which used liposomal AMP-B, and pure AMP-B encapsulated PVP/PVA MNs to treat ocular fungal infection [35].
