Evaluation of visual system morphologic and functional characteristics in patients after chiasmal sellar region tumors removal in postoperative period
We analyzed visual functions in patients with visual disorders, who underwent operations on chiasmal sellar region tumors removal in late postoperative period. 39 patients (78 eyes) were evaluated. Preoperatively in anamnesis all patients had the diagnosis of optic nerve partial atrophy. Patients were divided into two groups: 25 individuals (50 eyes) made Group I, who accepted basic therapy combined with semax at treating visual disorders, Group II were made of 14 patients (28 eyes), who had only basic therapy. Ophthalmologic research, which included computer (static) perimetry and optic nerve scanning laser retinal tomography, was provided for every patient. After the treatment fulfilled obvious increase of visual acuity and positive dynamics of perimetric characteristics was revealed in both groups, as well as stereometric parameters of optic nerve disk improvement and stabilization tendency. However, the treatment effectiveness in patients of Group I was higher. It was established that the research showed that semax, being included into complex therapy of optic nerve diseases treatment after chiasmal sellar region tumors, leads to visual functions improvement.
