a role of methods of visualisation in diagnostics of a malignant glaucoma

The additional valuable diagnostic information various techniques of visualisation, first of all, give ultrasonic research. The ultrasound A-mode allows to measure perednezadnjuju an eyeball axis; at a malignant glaucoma it makes less than 22,0 mm [2, 35, 51, 113, 125].

At V-scanning additional chambers in a vitreous [13, 51, 113, 115, 121] are taped forward rotation tsiliarnogo a body and an irido-lenticular diaphragm (fig. 8-10 see).

Fig. 4. A rotation UBM-PICTURE tsiliarnogo bodies and iridohrustalikovoj diaphragms. The angle of the forward chamber is closed [41].

At last, by means of UBM it is possible to receive images of a forward segment of an eye, a cornea, an iris, a lens and tsiliarnogo bodies in a cross-section section at the permission 25-50 microns and getting ability on depth of 5 mm. This method helps to differentiate various anatomic mechanisms of a pathogenesis of various forms of a glaucoma [82, 113].

Ivanov D.I. allocates a number of UBM-SIGNS of a malignant glaucoma (tab. 2 see) [15].

From other methods of diagnostics it is necessary to mention fljuorestseinovyj the test [44, 55, 76] which allows to define report presence between forward and back chambers of an eye. Its technique consists in the following. Into an ulnar vein enter 10 ml of 10 % of an aqueous solution fljuorestseina and after a while carry out biomicroscopy
With the dark blue filter. Fljuorestsein gets from the back chamber into a lobby to what its occurrence in the field of a pupil or a basal coloboma (in case of pupil blockade) testifies. Then concentration fljuorestseina in the forward chamber quickly accrues. Occurrence fljuorestseina in the forward chamber of both eyes should occur through identical time intervals (as it is surveyed as diagnostic criterion).
