AIM: Familiar with the treatment of various forms of Browns syndrome and its success. To document preparation of the expander own design. MATERIAL AND METHODS: In the years 1996-2016 was operated 33 pacients with congenital Browns syndrome by using an extension of its tendon expander at the Eye Clinic of the University Hospital Vinohrady in Prague. Author proves photographs preparing expander own design and modified surgical technique. It was also operated on 10 patients for accompanying Y-exotropia. Eleven patients with acute form of Brown´s syndrome in the pulley of upper oblique muscle applied Betamethasoni. RESULTS: The using expander own design - non-resorbable Ethibond 5-0 cauted silicone cannula - held at congenital form of Browns syndrome, without a weighty complication or its exclusion in the period. The result of the performance was determined age of patients at the time of implantation of the expander. Preschoolers postoperative condition was fully compliant, this expander standardized vertical mobility. The vertical alignment motility is reduced with advancing age, especially in adulthood. Optimal surgical procedures at Y-exotropia were antepozice with recession of the inferior oblique muscle possibly supplemented by retroposition ipsilateral external rectus. The application efficiency of Betamethasoni for acute form of Brown´s syndrome in the pulley of upper oblique muscle was successful in only two weeks after the initial symptoms vertical diplopia. CONCLUSION: Expander own design which represented non-resorbable Ethibond cauted silicone cannula was very effective in dealing with congenital form of Browns syndrome. The application of glucocorticoids in the pulley of upper oblique muscle should always be a quantity result.Key words: Browns syndrome, Betamethasoni, expander, Ethibond, silicone cannula, Y - exotropia.
