The article presents a case of Urrets-Zavalia syndrome development in a patient after a subtotal penetra ting keratoplasty, carried out for corneal opacity. Since this syndrome was diagnosed in time, it was possible to avoid further complications and worsening of visual functions in 25-year-old patient.

Primary endothelial dystrophy of the cornea is a fairly common disease in people older than 50 years. Well-developed methods of conservative treatment, as a rule, do not lead to improvement or stabilization of the functional state of the cornea. The choice of tactics of surgical treatment from the existing variety of techniques is complicated. There are isolated reports of the restoration of corneal transparency after descemet membrane removal. The author's method of endothelial corneal dystrophy treatment addressed in this particular clinical case - a combination of isolated descemetorhexis and collagen cross-linking - resulted in impressive increase in visual acuity and significant improvement in objective criteria for the morpho-functional state of the cornea.

The article reviews the literature on the classification of endothelial-epithelial dystrophy (EED) of the cornea. The description of endothelial structure, etiology and pathogenesis of the corneal EED are described. Based on own multiple observations and modern methods of corneal tissue imaging, a new modification of the EED classification by V.V. Volkov and M.M. Dronov was created and is presented in the article. This classification makes it possible to more accurately determine the etiopathogenesis of changes in corneal layers and to choose a most rational and effective treatment method.

Introduction. Mechanical conjunctivitis is a rare form of eye surface inflammatory condition. One of its types, a mucus fishing syndrome, leads to a chronic eye surface trauma. Purpose. To review the available literature data on the mechanical conjunctivitis prevalence, and to describe the diagnosis and treatment methods of its rare type, the mucus fishing syndrome. Materials and methods. The article describes the case of the mucus fishing syndrome development in a patient suffering from this type of mechanical conjunctivitis for about 3 years. Results. The correct diagnosis was not established in our patient for a long period of time that is why an improper treatment had been prescribed, which led to complications and to the need for surgical treatment. Conclusions. The prevalence of mechanical conjunctivitis is low, and in the available literature, there are only 4 publications on the topic. The mucus fishing syndrome should be treated in cooperation with a psychiatrist, since the usual use of topical reparative and lubricating therapy is not enough.
