Fungal keratoconjunctivitis is one of the more serious forms, and even with medication 15-27% of patients still have uncontrolled disease because the fungus is very aggressive and can enter the anterior chamber from the cornea, which will make endophthalmitis more difficult to control. The current antifungal drugs have poor sensitivity, poor permeability, and the antifungal drugs themselves have toxic effects. Typical corneal lesions in fungal keratitis can be seen as fungal tesserae, pseudopods, satellite foci, immune rings, endothelial spots, anterior chamber pus, etc. Having anterior chamber pus means that the infection has reached the corneal stroma, and some have penetrated the posterior elastic layer. The pus in the anterior chamber is 15%-30% before the corneal perforation, the pus has mycelium, most of it is reactive pus accumulation, when the corneal perforation after the anterior chamber pus up to 90% has fungal mycelium appear, endophthalmitis is very difficult to control, so fungal conjunctivitis is really terrible.
