摘要:

251 eyes underwent the combined procedure of perforating keratoplasty and intracapsular cataract extraction from 1968 to 1983. The preoperative preliminaries as well as the intraoperative details are described. The histological diagnoses were Fuchs’ endothelial-epithelial dystrophy, keratoconus, leukoma adherens and different kinds of keratitis. 89% of the grafts were clear, 11% irreversibly cloudy. Visual acuity was improved in 88%. Postoperative high intraocular pressure was no special problem and not affected by the combined procedure. Vitreal complications were seen in only 14%. The diameter for transplant and patient’s cornea can be reduced to 7.3 mm for both.

摘要:

The proposed method allows to discover and quantify small changes in series of fundus photographs which are normally not directly comparable. The principle of geometric conformality of small parts between the fundus and its photographs is developed into a practical method of stereoscopic measurement, numerical adjustment and quantitative evaluation. Very high accuracy is possible without special conditions on repeated fundus photography. The aim is to create a theoretical and methodical basis for ophthalmoscopic change detection with image-processing computers

摘要:

Indocyanine green angiograms of the macular region in 40 human eyes were evaluated in order to demonstrate the characteristics of the circulatory patterns of the submacular choroid. During both the early and the late phases of choroidal fluorescence nonuniform fluorescence was found. This implies the existence of watershed zones between choroidal arteries and between choroidal veins. A horizontal line running through the fovea was found to form a boundary between arterial systems, and also, in the majority of cases, between venous system.

摘要:

The choroidal circulation was studied in 27 eyes with choroidal neovascular diseases by means of fluorescein and indocyanine green (ICG) angiography. In 10 of the cases the disciform response was seen to be associated with either watershed zones of the choroidal circulation or with areas of choroidal circulatory disturbance. This is consistent with the theory that hypoxic regions of the choroid are the underlying cause of macular disciform response.

摘要:

Miotic-induced retinal detachment (RD) is a condition that is not recognized as such by common consent. Clinically it has been shown that all miotic agents, whether strong or weak, can precipitate an RD, if there are additional contributing factors like high myopia, peripheral lattice degeneration of the retina, pathological vitreoretinal changes and previous history of an RD in the other eye, which all increase the basic risk of RD. Pilokarpin lameller 11 mg® represents a form of miotic therapy having initially only a moderate accommodative and miotic effect, which further declines to a level of steady state during the next hours. Because the time interval after which a new Pilokarpin lameller unit is required lasts up to 1 week, the total amount of accommodation and miosis is much smaller than when applying daily 2% pilocarpine drops. However, it seems important, before the start of any kind of miotic therapy, to perform a careful examination and management of virtually all detachment-prone patients. This case report deals with an RD which occurred after 2 days of treatment with Pilokarpin lameller (Ocusert®) 11 mg in a myopic patient who had a juvenile type of glaucoma and previous history of an RD in the other eye.

摘要:

Conjunctival biopsies of 11 patients with sicca syndrome were studied under light and transmission electron microscopy. The notable findings were vasculitis of the conjunctival vessels. There were severe changes in the microvilli, namely a loss of microvilli and decrease in their height, measuring approximately 1,000–2,000 A, in comparison with microvilli of the control conjunctiva, measuring 4,000 Å in height. There was no branching yet or fusion of microvilli.

摘要:

A 71-year-old patient died 4 weeks after the occurrence of incomplete occlusion of the central retinal vein. Histology of the two bulbi was compared with the photographic and fluorescenceangiographic findings of the fundus. Histologic evaluation showed that the occlusion had been caused by a thickening of the vein wall due to proliferation of fibrocytes and histiocytes just behind the lamina cribrosa. There were no signs of phlebitis or thrombosis.
