[Detection of early cataract changes in the crystalline lens by using in vivo spectrophotometry of the eye]. / Wykrywanie wczesnych zmian zacmowych w soczewce przy pomocy przyzyciowej spektrofotometrii galki ocznej.

The aim of the paper was to study with the use of in vivo spectrophotometry of the eye the threshold values of the registered light above which one can observe clinically visible opacities of the lens. The performed experiments did not however show any major differences in the values of the registered light between persons with early cataract and control group because of considerable scattering of the results in both these groups. In order to explain the prognostic value of the in vivo spectrophotometry of the eye it is necessary to perform long-term observations of the further fate of persons with high values of the registered light.

[Effect of cataract extraction on the results of in vivo spectrophotometry of the eye]. / Wplyw usuniecia soczewki na wyniki przyzyciowej spektrofotometrii galki ocznej.

The authors compared the results of in vivo spectrophotometry of the eye in persons with a normal lens, in patients with aphakia and after an operation of intraocular lens implantation. The results received show that in the range of 400-500 microns half of the light registered by the spectrophotometer is connected with the lens in the eye. This speaks for the assumption that in vivo spectrophotometry in this range of the wave length may be one more method enabling an objective evaluation of the transparency of the lens. In the case of patients after operation of implantation of an intraocular lens the quantity of of the light reaching the retina is only slightly larger than in persons with a normal lens.

[Studies of the changes in crystalline lens transparency in rabbits with experimental cataract]. / Badania nad zmianami przezroczystosci soczewek ocznych w doswiadczalnej zacmie u królików.

Changes of the transparency of lenses were checked by means of in vivo spectrophotometry of the eye ball and by light transmission through extracted lenses in the course of experimental early cataract in rabbits caused by naphthalen. The results of investigations show that changes of lens transparency evaluated by means of in vivo spectrophotometry of the eye appear earlier than the clinically seen opacity. It speaks for the advisability of undertaking of further studies on the possibility of utilizing this method for detection of precataractous conditions in humans.

[Studies of the changes in crystalline lens transparency in subjects at risk of developing cataract]. / Badania nad zmianami przezroczystosci soczewek u osób zagrozonych rozwojem zacmy.

The aim of the survey was a comparison of transparency of the lenses examined by means of in vivo spectrophotometry of the eye in metalurgists threatened by development of cataract--with the results obtained in persons not engaged in metalurgy and selected by chance from the population. The investigations showed that the transparency of the lenses was lower in the group of the metalurgists than in the control group in spite of the fact that the ophthalmological examination did not detect any lens changes. The results of this study show that the in vivo spectrophotometry may find some employment for detection of changes in the lens which may occur in persons threatened by development of cataract.

[Retinal detachment as a complication of lensectomy in post-traumatic cataract]. / Odwarstwienie siatkówki jako powiklanie po lensektomii w zacmie urazowej.

Presented were personal observations concerning 76 patients with traumatic cataract who underwent lensectomy. In 12 patients the retina detached in a various postoperative period. Causes and mechanisms of this complication were discussed.

[Our observations concerning the use of low temperature in the treatment of glaucoma]. / Obserwacje wlasne zastosowania niskiej temperatury w leczeniu jaskry.

Cyclocryoapplication in glaucomatous patients is performed since 1983 by the method settled on the basis of results of experimental investigations. Observations concern 174 persons with various forms of glaucoma. Best results were obtained in patients with glaucoma in the course of uveitis, with secondary glaucoma after perforating injuries and after intracapsular cataract extraction. Fewest favourable results were observed in patients with closed angle glaucoma.

[Results of trabeculectomy combined with intrascleral iridencleisis in the treatment of glaucoma]. / Wyniki trabekulektomii polaczonej ze sródtwardówkowym wkleszczeniem teczówki w leczeniu jaskry.

Surgical technique and clinical results of a new antiglaucomatous operation--so called trabeculectomy connected with an intraseleral iridencleisis are presented. The lowering of the intraocular pressure after the operation was obtained in 96% of the operated patients, in 88% of them without any additional pharmacological treatment. The complications rate was comparable with those which are occuring after trabeculectomy or iridencleisis. The obtained results indicate that trabeculectomy with iridencleisis should be an effective antiglaucomatous procedure.

[A new early symptom of maculopathy in juvenile diabetes?]. / Ein neues Frühsymptom der Makulopathie bei juvenilem Diabetes?

This report presents results of fluorescein angiography performed in 37 patients aged from five to 25 years and treated for diabetes for periods varying from two months to 17 years. Symptoms of microangiopathy were found in eight patients; in 18 others, functional disturbances of the macular pigment epithelium appeared in the form of "window defects." The authors stress the possibility of the occurrence of these initial signs of maculopathy even in the first years following onset of diabetes.
