Additionally, cells contained densely packed tonofilaments in the cytoplasm, numerous vesicular structures, and disappearance of dyskratosis desmosomes and interdigitations [16]. Topical management alone has not shown to reduce plaque size in the majority of cases [15] [14].

The corneal plaques in these patients were larger and led to severe neovascularization bilaterally, as well as total opacification in dyskeartosis eye.
