[Follow-up of children after toxoplasmosis infection in pregnancy]. / Nachuntersuchung von Kindern nach Toxoplasmosefrischinfektion in der Schwangerschaft.

A vival toxoplasmosis infection was diagnosed in 188 cases (3,8%) out, of 49,582 pregnant women routinely screened. 4 children live with congenital toxoplasmosis. Follow-up studies showed that 33 children have specific antibodies, 5 are with suspect clinical findings. Therefore is the conclusion that more late signs of connatal toxoplasmosis are to be detected by follow-up investigations.

[A case of papillophlebitis]. / Ein Fall von Papillophlebitis.

A case history of a young man with recurrent papillophlebitis. The fluorescein angiogram showed an extensive hyperfluorescence of the disk and surrounding retinal veins in the venous and late phase. The electro-ophthalmological findings were normal in both eyes, while computerized perimetry demonstrated an enlarged blind spot in the bad eye but was normal in the other. The paper concludes with a description of the differential diagnosis of papillophlebitis, papillitis and papilledema caused by vascular occlusive disease or increased intracranial pressure.

[Light and electron microscopy results following photocoagulation of ciliary processes with argon lasers]. / Licht- und elektronenmikroskopische Ergebnisse nach Photokoagulation der Ziliarkörperzotten mit dem Argonlaser.

The authors' own clinical observations have shown that a pressure-lowering effect in secondary glaucomas resistant to therapy can be obtained by photocoagulation of the pars plicata of the ciliary body using an argon laser. In order to be able to estimate the damaging effect of photocoagulation and thus to be able to administer it in a sensible dose, the authors applied this technique to four patients with tumorous eyes that had to be enucleated, with a subsequent histological and electron-microscopical scrutiny. The laser energy was varied from 750 to 2000 mW at a constant exposure time of 0.2 s and a dot size of 100 micrograms. With clear-refracting media an energy of 1000 mW brought about coagulative effects without any substantial side-effects. Damage was then generally restricted to the aqueous humorproducing formation, i.e., the ciliary epithelium and the adjacent stromal part.

[Assessment of lesions in various sections of the visual pathway]. / Die Beurteilung von Läsionen im Sehbahnbereich.

The suitability of ultrasonography, computer tomography and Octopus perimetry is illustrated with reference to an investigation carried out in 60 patients. First, the characteristic symptoms are described, depending on the localization of the lesion in the visual pathway. Then the advantages and disadvantages of the various examination methods are compared. In the orbita, echography is the most accurate method in the anterior segments, while the balance shifts increasingly in favor of CT toward the retrobulbar region. As far as intracranial tumors are concerned, there is good correlation between CT and VF findings in the case of sellar processes and pathologic changes of the midline and occipital lobe. In the frontotemporal region, on the other hand, VF defects are found in only one-half of the cases, while in the case of vascular lesions there is no apparent correlation between perimetry findings and the size of the lesion demonstrated on the computer tomogram. The importance of the Octopus for early recognition of such lesions is discussed.

[Surgical method for the treatment of irreversible angle-closure glaucoma and aphakic glaucoma. Direct ciliary body coagulation with partial cyclodialysis]. / Operationsmethode zur Behandlung des irreversiblen Winkelblockglaukoms und des Aphakieglaukoms. Direkte Ziliarkörperkoagulation mit partieller Zyklodialyse.

Among 16 patients aged from 31 to 86 there were 13 cases of hemorrhagic glaucoma, three cases of secondary glaucoma from iritis and one case of secondary angle-closure glaucoma after trauma. Reduction in intraocular pressure was achieved by a surgical method which primarily aims to improve the outflow of aqueous humor. The ciliary body is laid bare by preparation of a scleral flap, a partial cyclodialysis is attached on both sides and the ciliary body is induced to stricture by coagulation, so that a large enough cleft is created. Before the operation, pressure ranged from 34 to 64 mm Hg; after the operation, during postoperative periods of observation lasting from two to 32 months, there were 14 cases in which the pressure was below 25 mm Hg and two cases with 30-40 mm Hg respectively. In view of the good results and the few complications, this method of operation can be recommended for treatment of both irreversible angle-closure glaucoma and aphakic glaucoma.

[Sjögren's reticular pigmentary dystrophy (author's transl)]. / Die retikuläre Pigmentdystrophie nach Sjögren.

An examination of two families with reticular pigmentary dystrophy of the retina is reported, and typical findings are reviewed. Visual actuity, visual fields, dark adaptation and color vision were normal; the photopic ERG was normal or subnormal, while the scotopic ERG was normal. Only the EOG findings were pathologic in all of the subjects examined. A description of the various forms of reticular dystrophy and of its differential diagnosis is followed by a discussion concerning the classification of all varieties of this disease as patterned dystrophies of the pigment epithelium.

[Electroophthalmological, Fluorescence angiographical and computer perimetrical examinations in cases of contusio bulbi (author's transl)]. / Elektroophthalmologische, fluoreszenzangiographische und computerperimetrische Untersuchungen bei Bulbuskontusionen.

In seven patients with diminished visual acuity, caused by oedema of the retina after contusio bulbi, the EOG, the photopic and the scotopic ERG as well as the VECP, elicited by luminance (H-EP) on the one hand and by pattern reversal-stimulation (M-EP) on the other hand, were registered. These registrations were made both during and after the acute phase. The results were then compared with the results of the normal fellow eyes. Additional fluorescence-angiographic and computer-perimetric examinations were performed. All EOG and ERG components studied showed a significant reduction in the acute phase and a significant increase -- with the exception of the photopic b-wave -- in the regression of the oedema of the retina. However, the values of the affected eyes never reached the values of the normal fellow eyes. The different behaviour of the H-EPs and the M-EPs is striking. While the medium values of the H-EPs showed little reduction in all examinations, the M-EPs showed a highly significant decrease or increase, with the visual acuity and the M-EP showing corresponding behaviour.

[A case of unilateral retinitis pigmentosa]. / Ein Fall von einseitiger Retinopathia pigmentosa.

A case of unilateral retinitis pigmentosa observed over a period of 15 years is reported. The affected eye showed all typical pathologic manifestations, while in the healthy eye all findings--including ERG and EOG-- were normal. In spite of the unequivocal ophthalmological diagnosis the condition should be regarded as a tapetoretinal degeneration with the clinical picture of unilateral retinitis pigmentosa so long as there is no evidence that it is hereditary.
