[Effects of petroleum derivatives and psychological stress on eye changes in prospective studies]. / Wplyw pochodnych ropy naftowej i stresu psychicznego na zmiany w narzadzie wzroku w badaniach prospektywnych.

Prospective study of workers exposed to simultaneous action of petroleum derivatives and psychic stress proved statistically remarkable differences between the first study and control study (after two years) as related to macular degeneration and opacification of the lens. So far, the results do not seem to point to these phenomena as related to the differences of age and training period between the two groups. For the ultimate assessment of the effect of simultaneous intoxication with petroleum derivatives and psychic stress, it is necessary to confront the results of the study with those obtained after examining the control group including persons of the same age.

[The state of the organ of vision in workers in the petrochemical industry. I. Results of ophthalmological examinations]. / Ocena stanu narzadu wzroku pracowników petrochemii. I. Wyniki badan okulistycznych.

The ophthalmological examinations of petrochemical plant workers that have been carried out so far did not enable working out a simple method of rapid ophthalmological evaluation of subclinical aromatic hydrocarbons poisonings. Neither the results of our own studies nor the experience of other authors explained fully the pathogenesis of the described spot lesions. Further observations are advisable to account for that issue.

[Evaluation of the organ of sight in workers at the Masovian Refinery-Petrochemistry Plant. II. Correlation of the results of ophthalmological tests with the results of specialized and laboratory tests]. / Ocena stanu narzadu wzroku pracowników MZRiP. II. Korelacja wyników badan okulistycznych z wynikami innych badan specjalistycznych i laboratoryjnych.

Basing on the results of examinations of 752 workers of the Refinery-Petro-chemistry Plant, correlations have been searched for between changes in the macula region of retina and disturbances found due to other specialist tests (internal, laryngological, dermatological), as well as laboratory--and toxicological investigations. A statistically significant correlation was found between changes in the macula and dysgeusia at the water-sewage division as well as the level of triglycerides at the phenol-and-total cholesterol division. A strict correlation was found between an increase in arterial hypertension and the rate of macula changes.

[Corneal sensitivity in workers in contact with petroleum products]. / Czucie rogówki u pracowników majacych kontakt z pochodnymi ropy naftowej.

Evaluation of the corneal sensitivity was carried out in 251 workers who have had a direct contact with petrol and its derivates and in 45 persons of a control group. It was established that the corneal sensitivity--especially in its central region--was distinctly lowered in persons employed in the department of asphalt oxidation and cleaning of sewages. This concerned particularly the workers with a long-lasting, many years service.
