[A case of Jodassohn-Lewandowsky syndrome].

A case of a 25-year-old female patient with reduction of visual acuity, strabismus convergence with corneal scars and paralimbal neovascularisation of her left eye with skin changes of linear skin naevus type is presented. The diagnosis of Jadassohn-Lewandowsky syndrome was based on characteristic skin and eye disturbances. There are also typical changes in mucous membranes and central nervous system. The treatment is difficult and a certain role may be played by cosmetic and repair surgery.

[Studies on oxygen content in aqueous humor of the anterior chamber of the rabbit's eye--I. Oxygen content in aqueous humor of anterior chamber and arterial blood under physiologic conditions].

The measurements of the partial pressure of oxygen pO2 in the aqueous humor of anterior chamber in both eyes and arterial blood, using the electrochemical--polarographic method, under physiological conditions, have been carried out in 20 rabbits. The mean value of pO2 oxygen partial pressure in aqueous humor was 8.48 kPa, whereas in arterial blood was higher--9.69 kPa. The processes of infiltration (diffusion) from blood-vascular system and oxygen distribution in the aqueous humor of anterior chamber of the eye have been discussed.

[Studies on oxygen content of aqueous humor in the anterior chamber of rabbit's eye--II. Oxygen content of aqueous humor in anterior chamber and arterial blood in experimentally provoked ischemia].

The ligature of the right common carotid artery has been performed in 20 rabbits. Then, the partial pressure of oxygen pO2 in the aqueous humor of anterior chamber of the both eyes and in the right and left ear artery was measured. An electrochemical polarographic oxymeter was used for this purpose. The measurements were carried out on the second day, in a week and in one month after performing the ligature. A statistically significant decrease of pO2 in aqueous humor of anterior chamber of the right eye and of ear artery on the right side was observed, especially on the second day and after a week. Blood circulation stoppage within the right common carotid artery causes, in spite of the preservation of collateral circulation, a significant pO2 decrease in aqueous humor. The pO2 measurement would be a valuable supplement to the methods applied in the measurement of ear artery blood circulation.

[Simple glaucoma--when to operate?].

An analysis of visual field changes in 105 patients treated conservatively and in 57 patients treated surgically is presented. Both groups have been observed for 5 years. It was established that the surgical procedure should be undertaken before the development of the changes in the visual field.

[Late results of the surgical treatment of primary glaucoma].

The paper presents the results of surgical treatment of 171 eyes with primary glaucoma. Evaluated was the visual acuity, the visual fields, the coefficient of the aqueous outflow and the mean values of the IOP, 5, 3 and below 3 years since operation. The pharmacological treatment was included in 18% of the operated patients.
