[To the prevention of recurrent dacryocystitis after surgical treatment].

The efficacy of collagenase KK was evaluated in the treatment of 121 patients with lacrimal duct diseases. Collagenase KK used to prevent recurrent lacrimal duct disease contributed to a significant relief of an inflammatory process (by an average of 2.04+/-0.

[Experience with endoscopy used in surgery for complicated cataracts].

The paper describes a procedure for intraoperative diagnosis of Zinn's zonula defects in intraocular lens (IOL) implantation. Studies were made during treatment of 14 patients (14 eyes) with complicated cataract, in whom intraoperative endoscopic diagnosis of dislocation of the lens was made. The diagnosis of third-degree lenticular subluxation was verified in 9 patients; in 5 patients who were biomicroscopically diagnosed as having second-degree lenticular subluxation, its third-degree was revealed by intraoperative endoscopy.

[Experimental determination of a safe dose of the enzyme collagenase agent for subconjunctival and retrobulbar administration].

The authors carried out two series of experiments using 32 eyes of 16 rabbits. The enzyme collagenase agent was daily injected, by increasing doses up to 25, 50, 75, and 100 units for subconjunctival ocular (Series 1) and retrobulbar (Series 2) injections. The control groups included 3 rabbits in both series (6 eyes).

[Comprehensive ultrasound diagnosis of orbital tumors and preudotumors].

A comprehensive ultrasound examination was made in 37 patients with orbital tumors and pseudotumors. The basic differential diagnostic sonographic and Doppler signs were defined in capillary hemangioma, vasculitis at the stage of infiltration and malignancies of the orbit.
