THE WAYS OF OPTIC NEUROPATHY PREVENTION IN MILD TRAUMATIC BRAIN INJURY
Introduction: Traumatic brain injury affects the most active part of population. Ocular pathology is a frequent complication of traumatic brain injury. Revealing ocular signs in acute stage of traumatic brain injury is still disputable. Goal of the research: Investigating clinical and functional disorders of fundus and visual analyzer, elaboration and substantiation of pathogenetic direction of prevention of optic nerve atrophy with estimation of its efficiency in the acute period of mild skull brain injury. Material and methods: 110 patients with mild skull brain injury. The age of injured persons was from 17 to 82 years. Males about 77 persons (77.0%), females - 23 (23.0%). Results: The normal borders of visual field were determined in 84.4% at isolated severe skull brain injury and in 69.1 % - in combination with mild skull brain injury. The data of research of cerebral and orbital hemodynamics showed that the injured patients with mild skull brain injury register the true (p<0.05) increase of resistance index, especially in the group of patients with optic neuropathy. Conclusion: Optic neuropathy in acute period of traumatic brain injury diagnosed in 19.6% cases, optic disc congestion in 9.8% и retinal angiopathy in 25.5% cases. Improvement of visual acuity, decreasing of resistance index and increasing of blood stream linear velocity in cerebral and ophthalmic arteries as a result of mild traumatic brain injury complex management considering ocular pathology have been achieved.
