It some cases, the infection can then group around corneal nerves, producing radial deposits (radial keratoneuritis), and causing extreme pain. These are features also seen in viral and bacterial keratitis, and may be misleading.[13][11][10] The organism is also capable of invading deeper into the cornea; using metalloproteases it is able to penetrate deep into the stroma of the cornea.[11] As the disease progresses, it may penetrate through cornea but very rarely causes infection inside the eye (endophthalmitis) due to a robust neutrophil response in the anterior chamber.[11][14]
