[Ultrasonography in the combined modality diagnosis of intraocular tumors]. / Ul'trazvukovoe issledovania v kompleksnoi diagnostike vnutriglaznykh novoobrazovanii.

The paper is concerned with the description of potentialities of radiation methods (ultrasound B-scanning, computerized and MR-tomography) in combined diagnosis of intraocular tumors. Ultrasound investigation was performed in 62 patients, 42 of them were subjected to computerized tomography, 18--to MR-tomography. A leading role of ultrasound investigation was shown in the diagnosis of eyeball abnormalities and in the control of efficacy of eye tumor therapy. Ultrasound investigation plays a special role in abnormalities, accompanied by opacity of eye optic media. Computerized tomography is an adjuvant method of investigation to specify tumor spreading beyond the eyeball.

[The choice of the radiation parameters in the laser reconstruction of the pupil]. / K vyboru parametrov izlucheniia pri lazernoi rekonstruktsii zrachkovogo otverstiia.

The phenomenon of a "local punch" of tissues in the zone of nano- or picosecond impulses of neodymium: YAG-laser radiation focusing allows to increase energy in the pulse by one order as compared with traditionally used energy. At this, in order to achieve the initial effect it becomes possible to reduce the number of shots by two orders and thus to increase the spot of radiation. The summary energy of action absorbed in the eye remains the same and that's why the number of complications doesn't increase. The widening of possibilities to choose a laser source for micro- and macroperforations allows, when prescribing the treatment, to more reliably consider clinical peculiarities in each concrete case.
