Abstract: FIELD: medicine, ophthalmosurgery. SUBSTANCE: at ruptures stage I one should perform radial scanning of macular area by performing not less than 6 hourly scans, moreover, the center of each scan should be fixed in foveola's projection. Then scanning data: the presence of posterior hyaloid membrane (PHM)detachment, degree of PHM manifestation (higher, lower) and PHM fixation with fovea should be plotted onto eyeground scheme of corresponding eye having identical hourly marking and according to data of the highest PHM manifestation and, simultaneously, fixation with fovea one should conclude upon location and duration of prerupture area. One should mark this area at scheme. Then one should plot straight line from the middle of marked prerupture through faveola to make a mark at this straight line behind area of vascular arcades. During vitrectomy a surgeon mentally projects this mark from scheme onto eyeground and starts from this site PHM isolation towards prerupture center. At ruptures stage II one should perform radial scanning of macular area by carrying out not less than 6 hourly scans, moreover, the center of each scan should be fixed in foveola's projection. Then scanning data: the presence of macular rupture, the presence of PHM detachment and site of PHM fixation with fovea should be plotted onto eyeground scheme of corresponding eye having identical hourly marking. According to these data one should conclude upon location and duration of rupture, finally mark it upon scheme and plot straight line from the middle of rupture through foveola and on this straight line behind area of vascular arcades surgeon mentally projects the mark from scheme onto eyeground, and from this site starts to isolate PHM towards rupture's center.

After shell's flying out of the bore of the barrel due to accumulative energy in the storage cavity in the space behind the shell the stern of the shell is extended by attaching to it a conic form. The shell's device for increasing its range is made in the shape of a stern telescopic extender which has a hollow fairing firmly fixed on the stern section and a mobile cap located in it with possibility for axial travel with follow-on fixation with the help of an expanding spring ring. The hollow fairing and the cap are made in the shape of cylinders connected with truncated cones of the same obliquity. In the center of the cap there is a throttle opening connecting the space behind the shell with storage cavity formed by the shell's bottom shear and the mobile cap.
