[The use of Soviet-made flexible ophthalmic endoscopes during surgical interventions on the "closed" eye].

Possibilities of the usage of different models of flexible ophthalmic endoscopes in diagnosis and treatment of intraocular eye pathology have been studied. The paper presents data about the usage of endoscopes at the time of intraocular operations in the "closed" eye of 25 patients with pathologic changes of different etiology in the posterior segment of the eye (25 eyes). Comparative analysis of possibilities of the usage of different models has revealed advantages of endoscopes with combined observation and illumination channels and with a wide-angle objective. Different methods for the usage of flexible ophthalmic endoscopes are described. It is pointed out that ophthalmic endoscopy, by giving a surgeon additional information about intraocular changes, allows the operation of a closed type in vitreoretinal pathology to be much more effective.
