Dry eye syndrome associated with traumatic keratitis

Abstract

Dry eye syndrome (DES) is an urgent problem in healthcare practice worldwide. Various diseases of the eye are of particular importance for the development of this syndrome. A special place among the diseases leading to symptomatic DES with ocular surface lesion belongs to corneal injuries of traumatic origin. The frequency of post-traumatic complications of the eye, especially the cornea, remains high due to its anatomical location. And often these patients are at risk of secondary DES. For the pathogenesis of DES after ke­ratitis, ultrastructural changes in the cells of different corneal layers and the toxic effect on the tear film layers of preservative-containing drugs used in the treatment of keratitis are important. The purpose of the study was to assess the severity of secondary DES in patients after traumatic keratitis and the effectiveness of hyaluronic acid combined with antioxidants in the treatment of this pathology. An ophthalmological examination, functional tests were made, and the Ocular Surface Disease Index was used to evaluate the symptoms and severity of the disease. The criteria for the effectiveness of the therapy with hyaluronic acid in combination with vitamins A and E four times a day were: reduction of corneal syndrome, increase in the tear film break-up time, a decrease in subjective discomfort. Clinical observation of patients with DES after traumatic keratitis showed that the use of hyaluronic acid can result in a significant reduction or complete disappearance of subjective symptoms of the disease, sustained improvement in vision and increased stability of the tear film. The use of these eye drops makes it possible to reach compliance and shorten the treatment period.
