[Consequences of extraocular rectus muscle myotomy in rabbits--in vivo and pathomorphologic studies].

The aim of investigations was to evaluate the changes in the eyeball, after extraocular rectus muscles myotomy. In 16 rabbits two muscles and in 17 four muscles were cut in one eye; the opposite eye was control. In early postoperative period intraocular pressure was statistically significantly lower, as compared with the control eyes and it depended on the number of cut muscles. In histopathological examination, the most constant changes were dilatation of conjunctival vessels and pigment migration in the anterior uvea. Decreased intraocular pressure and pigment migration in iris and ciliary body were considered to be the symptoms of anterior segment ischemia.

[Tumor metastasis to the eyeball].

Clinical observations of 7 patients with metastatic intraocular tumors are presented. The primary sites of neoplasms were breast cancer in 4 women, pulmonary cancer in 2 men and in 1 cancer of prostate. In 4 patients metastases were observed also in the anterior segment of uveal tract. Secondary retinal detachment was found in 6 cases, central retinal artery occlusion in one and ciliary artery occlusion in another one. In spite of radio--and chemotherapy 5 patients died during 1-9 months and 2 remained under clinical observation.

[Obliteration of vessels growing into the cornea with the help of laser energy].

The vessels proliferating into cornea cause epithelium biotransformation and lipid keratopathy, decreasing corneal transparency. In 9 patients (10 eyes) argon laser obliteration of these vessels was performed. In 8 eyes improvement of corneal transparency and visual acuity was achieved, in other two the neovascularization was restrained. The best results were observed in lipid keratopathy.

[Stickler's syndrome].

Stickler's syndrome or congenital, progressive arthro-ophthalmopathy refers to disturbances of the connective tissue of the organism but mainly the osteoarticular and visual systems. In the visual system one discovers a congenital high myopia, pathological changes in the vitreous in the form of membranes and proliferative bands as well as retinal detachment. A metabolic defect concerning the hyaluronic acid and the collagen of the 2-d type is assumed to be the cause of this syndrome.

[Our results of laser trabeculoplasty in simple glaucoma].

In 24 patients with simple glaucoma in whom the IOP did not normalize under the conservative treatment the authors checked--between others--the Po, the outflow coefficient (C) and calculated Po/C. Laser trabeculoplasty was performed subsequently. The enumerated indexes were examined the day after surgery, then after the 1-st and 2-nd week, after a month and 2 months. In the majority of cases the coefficient C showed an improvement and normalization of the IOP distinctly seen till the 1-st month after operation. In subsequent observations 5 persons showed a renewed deterioration of the hydrodynamic conditions and the intervention was repeated leading to an improvement in 3 cases. In consideration of the lack of normalization of the IOP in 2 persons it was necessary to subject them to a surgical procedure.

[Effects of petroleum derivatives and psychological stress on eye changes in prospective studies].

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.

[State of the eyes in welders of Division M-5, Brown Coal Mine in Bełchatow].

Sight organ impairments have been compared in a group of M-5 Division welders, Brown Coal Mine in Bełchatów, and control group of randomly selected administration workers. In the group of welders statistically more frequent were degenerative changes in the eye macula, melanomatosis and conjunctivitis. Those with changes in the area of the macua lutea and melanosis conjunctivae should undergo periodic ophthalmological control (dispensary groups).

[Function studies of the organ of sight in welders of the M-5 Division at the brown coal mine in Bełchatów].

The results of functional examinations of the sight organ (vision acuity, colour differentiation, ability to differentiate shapes in darkness at lowest luminances, glare test, stereometry), both in welders and controls, were not significantly changed after eight-hours' work. On the other hand, a statistically significant difference was found between the groups as regards colour differentiation, visual capability within the lowest luminations, and glare test.

[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].

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.

[The state of the organ of vision in workers in the petrochemical industry. I. Results of ophthalmological examinations].

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.
