The objective: comparison of some characteristics of visualization of the operating field with the use of fiber-fiber and lens fetoscopes.
Materials and methods. A comparison was made between the characteristics of a classic lens fetoscope with a diameter of 2.0 mm, a lens fetoscope with a diameter of 2.0 mm, and flexible fiber optics 1.0 mm in diameter.
Results. It was revealed that the use of ultrathin optics allows to significantly reduce the size of the holes in the amniotic membranes without reducing the visualization area, however with a noticeable loss of image quality.
Conclusion. The use of ultrathin fetoscopes is a promising direction in fetal medicine, because despite the relatively poor image quality, the area of visualization of the operating field is identical. Correct juxtaposition of the surfaces of the fetoscope and trocars, as well as the adjustment of the intensity of the light beam, can prevent negative optical effects.
Key words: fetoscope, amniotic membranes, invasive procedures.
