Specific growth rate of bifidobacteria cultured on different sugars.

The ability of six bifidobacterial strains (3 of human origin and 3 isolates from fermented milk products) to utilize glucose, lactose, melezitose, sucrose, raffinose, and stachyose was determined. Dairy-related bifidobacterial strains were identified as Bifidobacterium animalis (2 strains) or as B. pseudolongum (1 strain). Human strains included B. longum (2 strains) and B. breve (1 strain). All strains fermented lactose, sucrose, raffinose, and stachyose. Melezitose was utilized only by B. longum. B. pseudolongum did not ferment either glucose or melezitose. All isolates had a higher specific growth rate on raffinose and stachyose than on glucose. Dairy strain grew slowly on glucose compared to human strains.

[Initial experience with toric intraocular lenses].

The aim of cataract extraction with implantation of intraocular lens is the astigmatically neutral result. This neutral cataract incision is reached by the method of phacoemulsification with a small incision and implantation of foldable intraocular lens. In case of preoperative astigmatism is an effective method the implantation of a toric intraocular lens. The authors evaluate the first results of pre and postoperative refraction after implantation of ten toric intraocular lenses.

[Laser trabeculoplasty--present and future perspectives].

Laser trabeculoplasty has been used in the treatment of various types of glaucoma for nearly 20 years. It's intraocular pressure lowering effect through enhancement of aqueous outflow is well documented. In spite of this, the precise effect of laser trabeculoplasty in the trabecular meshwork is only partially understood. It is related to laser wave length, laser power, burns location, number of shots etc. The effectiveness of laser trabeculoplasty diminishes over time, but can be renewed with re-treatment. Laser trabeculoplasty has connected with minimum complications and it is most effective in patients with primary open-angle glaucoma, pigmentary glaucoma and the exfoliation syndrome glaucoma, though the long-term results of this microsurgery laser treatment are not quite indisputable.

[Results of implantation of endocapsular distance rings].

Endocapsular distance ring increases possibilities of extraction subluxated cataract. Its importance consists of stabilisation of capsular bag and with the possibility of implantation posterior intraocular lens. In the group there are 20 patients with implanted 21 distance rings. The period of follow up was 4-24 months. We used of a polymethyl methacrylate distance ring from firms Erilens, Morcher and IOLTechnology. Indication for the implantation of a distance ring was dialysis less than 2 quadrants, it depends on size and type of distance ring. The authors evaluate complications during the operation and early and later results after operation.

[Treatment of postoperative astigmatism after perforating keratoplasty using the LASIK method].

The problem of postoperative astigmatism after perforating keratoplasty is complicated. Several possible methods of correction exist. The time and approach to correction of astigmatism after perforating keratoplasty is important. The authors present an account on a group of 10 eyes treated by the LASIK method on an apparatus Keracor 117. In four instances hyperopia with astigmatism was involved and in six eyes myopia with astigmatism, the mean age of the patients being 46.25 years. The mean values of the preoperative spherical hyperopic componenent was +1.37 D and of the myopic spherical component -2.12 D. The preoperative hyperopic astigmatism was +4.5 D and the myopic astigmatism -5.84 D. The follow up period was 9.5 months (1-25 months). The authors evaluate the postoperative natural vision, the resulting postoperative refraction, the incidence of complications and changes of endothelial cells before and after surgery. The resulting mean postoperative hyperopic astigmatism was +0.5 D and the myopic astigmatism -2.4 D. The reduction of values of hyperopic astigmatism was 88.9% and of myopic astigmatism 58.9%, the reduction of the spherical hyperopic component was 100% and of the myopic component 75%. On account of the stabilization of the postoperative refraction, low incidence of peroperative and postoperative complications and the insignificant decrease of endothelial cells the LASIK method is evaluated as effective.

[ProVisc--a new viscoelastic material for surgery of the anterior segment. A multicenter clinical study].

Within the framework of a multicentric clinical study which was implemented at nine selected departments a new viscoelastic material ProVisc of Alcon company was tested during extracapsular extraction of cataract with implantation of posterior chamber intraocular lenses. A total of 100 eyes of 100 patients were operated and all pre- and postoperative data were recorded in uniform protocols. The selection of suitable patients and the type of surgical procedure was within the responsibility of the surgeon. The type and frequency of surgical and postoperative complications was similar as when other viscoelastic material ProVisc can be recommended as safe and effective in modern surgery of cataract.

[Implantation of retropupillary intraocular lenses in post-traumatic conditions of the eye].

The investigation comprises the results of post-traumatic artephakias. In the course of 15 months the authors treated 15 patients with traumatic cataract after previous perforating or blunt eye injuries. In 12 patients after extracapsular extraction a retropupillary IOL was implanted. In three patients implantation was not performed. Retropupillary pseudophakia is the optimal correction of aphakia even in patients with previous serious eye injuries. A higher incidence of postoperative complications may be expected.

[Accuracy of ultrasound measurements of the axial length of the eye].

Ultrasonic assessment of the axial length of the eye provides important baseline data for the calculation of the dioptric power of an artificial intraocular lens. The accuracy of ultrasonic biometry performed by an OPHTASCAN B apparatus is discussed based on evaluation of a group of repeated measurements of the axial length and depth of the anterior chamber in 592 bulbi.

[Injuries of the orbit caused by foreign body].

Four cases of injury of the orbit by a big foreign body without damage to the bulbus are described. The bodies were extracted and the healing was without complications. Two of these bodies penetrated into the brain and in one case surgical intervention was necessary. In both instances vision was lost because of damage to the optic nerve.

[Combined use of ultrasound and radiodiagnostic methods in the diagnosis of posterior dislocation of the lens].

In a case record the authors present an account on a patient with an opaque media of the left eye on account of seclusion and occlusion of the pupil. The cause of the unilateral chronic uveitis was elucidated by ultrasonic examination with visualization type A. The cause was a calcified lens dislocated into the vitreous body and fixed to the posterior wall of the eye. The finding was confirmed by a negative X-ray picture and positive finding of a small foreign body with high density on CT. Dislocation of the lens occurred after a blow on the left eye during boxing 15 years before the patient sought medical assistance on account of a painful practically blind eyeball.

[Comparison of the predicted and actual refraction of the eye after intraocular lens implantation].

After previous assessment of the dioptric potency (by means of a SRK formula) the authors implanted the appropriate intraocular lenses. After 4-18 months following implantation the calculated refraction calculated before the intervention was compared with the postoperative reality. In 85% the difference was not greater than +/- 1.5 Dsf. The calculation of aniseiconia was made only in case of preoperative ametropia greater than +/- 2 Dsf.

[Reconstruction of the facial skeleton using Pallacos R].

Defects of the facial skeleton cause frequently severe aesthetic facial changes with negative repercussions also on the patient's mental state. The skeleton may be affected by injury, a neoplastic disease and iatrogenically when it is necessary to remove a part of the skeleton during operation. One possible way how to replace and reconstruct the skeleton is to use bone cement Pallacos R. This method was used in 8 patients with skeletal affections. The use of Pallacos R has the advantage that it can be used quickly, that it is easy to work with directly at the site of the defect and that its tolerance is satisfactory. It permits also to preserve the physiological shape of the paranasal sinuses. The method is one approach to individually indicated reconstruction.

[Complications of intraocular lens implantation].

The authors analyze the causes of per- and postoperative complications of implantations of intraocular retropupillary lenses. In a group of 132 extracapsular extractions of cataract with implantation of an intraocular lens no marked decentering was found. The most frequent postoperative complication were transitory striae and fibrin exudates in the pupil. Only once the "toxic lens syndrome" was encountered. The fine cilia of the posterior capsule, pigment dispersion and changes in the width of the pupil did not affect markedly the visual functions of the organ. The authors did not observe regenerating cataracts, or fibroses of the posterior capsule (mainly because of the short follow up period).

[Delayed extraction of an intraocular foreign body].

The authors describe two cases of siderosis of the bulbus which developed as a consequence of late diagnosis of intraocular foreign bodies. The character of siderosis differed, however, in the two patients. In the first patient the picture of generalized siderosis confirmed also by electroretinographic examination permitted the assumption of an adverse course of the disease already on admission, as was confirmed by the progression of the disease even after removal of the intraocular foreign body. In the second patient probable encapsulation of the foreign body led to focal siderosis and a favourable course of the disease.
