Случай успешного хирургического лечения трофической язвы роговицы

Abstract

Purpose. To present the results of clinical outcomes of modern high-tech surgical treatment of a patient with unilateral neurotrophic keratitis using layered keratoplasty, which helps to prevent the development of further irreversible complications. Material and methods. A 45-year-old patient, after a course of radiation therapy for a brain tumor with the development of numbness on the upper left-side of her face, conjunctiva and cornea underwent six months later cataract phacoemulsification with IOL implantation in the left eye. After 2 months the patient’s vision decreased significantly, the examination showed that she developed neurotrophic keratitis on the operated eye, followed by progression and transformation into a trophic corneal ulcer with descemetocele. Results. In order to prevent further complications in the form of corneal perforation, anterior deep layered keratoplasty with a small diameter graft was performed. Extremely slow epithelialization was noted, and therefore a successful and effective biopsy of the cornea with an amniotic membrane was carried out. Conclusion. Cataract extraction in patients after radiation therapy with further loss of corneal sensation is extremely risky and can lead to serious consequences, in particular, the development of neurotrophic keratitis and corneal trophic ulcers. The use of the surgical technique of anterior deep layered corneal transplantation is an effective method of treating trophic ulcers, and the technique of performing the operation has certain features compared to the classical technology and requires extensive experience of the surgeon. However, the use of this method of surgical treatment for corneal trophic ulcers with descemetocele due to neurotrophic keratitis developed on the basis of radiation therapy does not always lead to success. In this case, the additional use of the amniotic membr ane for therapeutic purposes contributed to the r elief of the pathological process, paving the way for subsequent surgical interventions to restore high visual acuity i n the future.
