[Detection of early cataract changes in the crystalline lens by using in vivo spectrophotometry of the eye].

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].

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.

[Examination of the visual system in boxers].

Ophthalmological examinations were performed in 139 boxers. They showed that the injuries concerned most frequently the ocular adnexa and not the eye globe itself. Only two contestants who practiced boxing for more than 10 years exhibited peripheral opacities of the lens and pale foci with shifting of the pigment at the fundus periphery connected with a deepening of the filtration angle; this could be caused by a contusion of the eye. It was demonstrated that the introduction of safety helmets distinctly reduced the number of eye injuries in boxing.

[Experimental studies of using highly fluorinated alkane in the surgical treatment of retinal detachment].

Fluids which are heavier than the vitreous fluid find recently their application in retinal detachment surgery. They fall down to the bottom of the eye and exerted pressure on the retina. Experimental investigations have been carried out on the possibility of application of these highly fluorinated alkane for operation. It has been demonstrated that this compound was very well tolerated by the tissues. It did not provoke any inflammatory or toxic reaction and did not cause any opacification of the optic media. On the spot of adherence it filtered in small quantities to the internal retinal layers. It could find probably its application in ophthalmic surgery.

[Color vision in patients with juvenile onset diabetes mellitus].

A considerable dependence was revealed between the occurrence of disturbances of color vision and the advancement of diabetic retinopathy. The examination of color vision represented in a great part the degree of the functional damage of the cones, a damage which was a consequence of increasing vascular changes at the eye fundus.
