Abstract:The article discusses the effectiveness of accelerated collagen crosslinking in the treatment of patients with corneal diseases, a common basic pathogenetic link of which is endothelial corneal decompensation. This method was used to treat patients with bullous keratopathy and endothelial dystrophy of Fuchs’ cornea with a long postoperative follow-up. In connection with the controversial results of researchers, reflecting the positive dynamics of the postoperative period, the question of the expediency of acce… Show more
BACKGROUND: Degenerative changes of cornea after transection of the trigeminal nerve were first described by F. Magendie in 1824. Neurotrophic keratopathy is considered to be an orphan disease which lately has been recognized more and more often. According to literature data, neurotropchic keratopathy affects 5 individuals in 10,000. The diagnosis is difficult due to the lack of information about this condition, the rare occurrence and the presence of a large number of etiological factors.
AIM: To determine the causes of the neurotrophic keratopathy development and the treatment tactics in a patient with a neurological disease. The article presents a case of neurotrophic keratopathy in a patient with Wallenberg Zakharchenko syndrome.
Because of the fact that neurotrophic keratopathy was diagnosed late and the correct treatment did not start in time, further progression of the pathological process in the cornea could not be avoided. Periodic recurrence of neurotrophic keratopathy is associated with an underlying chronic neurological disease.
CONCLUSIONS: Neurotrophic keratopathy requires early diagnosis. In certain clinical cases, for the successful treatment of this pathology, it is necessary to prescribe systemic therapy.

Infectious crystalline keratopathy (ICK) is a rare cornea disease, manifested by gray-and-white tree-like or needle-like stromal opacities with minimal signs of inflammation. The disease is caused by the colonization of microorganisms on the corneal stroma and their formation of biofilms, making them extremely resistant to treatment with antibiotics and to the immune response of the patient. Typically, the most important risk factor for ICK development is the presence of an immunodeficiency cornea condition with long-term topical steroid therapy, which is normally prescribed after keratoplasty. Two clinical cases of ICK are discussed in which the reduction of topical glucocorticoids and the intensive use of antibiotics did not result in positive clinical changes. Only after an accelerated crosslinking procedure (PACK-CXL), needlelike opacities disappeared in the area of microbial invasion and signs of infiltration appeared, indicating the restoration of the local immune response. This phenomenon is likely due to the destruction of the biofilm and the microbial agents themselves, which afterwards contributed to a more effective impact of the antibacterial drug. This combined treatment led to resorption of the inflammatory focus with the formation of local opacification. The effectiveness of PACK-CXL in infectious processes is explained by the effects of both riboflavin and ultraviolet radiation. No literature references on the use of cross-linking in the treatment of ICK are available. In our opinion, cross-linking in early ICK patients after keratoplasty is justified by the inability, in some cases, to completely discontinue glucocorticosteroid therapy, as this will greatly increase the chances of rejection and graft jailure. PACK-CXL can be an effective way of destroying the biofilm in the corneal stroma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
