摘要:

Progress in the treatment of vitreoretinal proliferation has led ophthalmic surgeons to combine vitrectomy, peeling of the epiretinal membrane and silicone oil injection with surgery on the retina. The intervention consists either of a circular subtotal retinectomy leaving only the retina of the posterior pole and a retinal crown of two papillary diameters in width at the periphery of the temporal vessels; or, when the upper retina is already reapplied by silicone oil, of a semicircular lower retinotomy that suppresses the tractions against which the silicone oil is powerless. The sectioning is preceded by an endodiathermy that must be very precise, in order to avoid hemorrhages which are the major complication of the intervention. These preliminary studies will be followed by a detailed study when a larger number of cases is available.

摘要:

A historical recall and an attempt to simplify the numerous terms used to designate laser treatments for primary open-angle glaucoma (POAG) are presented. There are two main types of laser treatment for POAG involving two entirely different procedures. The first one, contemporary with the beginning of laser photocoagulation, imitates the action of the scalpel, namely goniotomy ab interno or trabeculotomy ab externo. The goal of this early procedure was to produce a through and through trabecular hole but instead of the cutting edge of the knife, it uses the explosive effect of the laser. This procedure has been given numerous names. Among the most frequent ones, we find: ‘laser trabeculopuncture’, ‘laseropuncture’, ‘goniopuncture’, ‘laser trabeculectomy’, ‘laser trabeculotomy’, ‘laser trabeculopexy’. We prefer to gather them under an explicit generic term: ‘laser trabeculoperforation’. The results of this procedure have been very disappointing until now, particularly with conventional lasers, e.g. continuous-wave argon laser, owing to the predominance of their thermal effect over their explosive effect and also to the great scarring property of the trabecular meshwork. In the second type of glaucoma laser treatment, instead of trying to make a patent hole in the trabecular meshwork, the surgeon seeks to reshape the inner trabecular surface by means of argon laser microscars in order to produce a reversal of the trabecular collapse, which is now considered to be one of the major etiologies of POAG. Since our first attempts in 1981, we have chosen to describe this procedure with the term: ‘laser trabeculoretraction’ because this presents a triple advantage: it accurately localizes the site to be photocoagulated, i.e. the trabecular meshwork; it illustrates clearly the theoretical mechanism of action which is essentially mechanical and backed up by an increasing number of arguments; lastly, it contrasts without ambiguity with the early procedure which seeks to produce a completely patent through and through trabecular hole, i.e. laser trabeculoperforation. In the English literature, the term laser ‘trabeculoplasty’, more widely used to describe the technique of Wise seems less precise to us. Furthermore, it can lead to confusion with trabeculoperforation procedure. There is also a difference in the efficacy of these procedures: laser trabeculoretraction has been considered ‘a real quiet revolution in the treatment of POAG’.

摘要:

The authors present some guidelines on laser therapy (Argon and/or Yag) application on the different types of glaucomatous pathology. These therapeutic guidelines are the result of a 3-year experience of constant laser therapy application on glaucoma. The case reports include 196 A-laser trabeculoplasties, 34 A-laser iridotomies, 158 Yag-laser iridotomies, 31 gonioplasties, plus numberless combined treatments (iridotomy-trabeculo-plasty, gonio-trabeculoplasty, gonioplasty-ciliary body photocoagulation, and so on). The authors conclude by reaffirming the considerable reliability of these techniques, given a prolonged follow-up; they also advance some new therapeutic hypotheses on laser operation in glaucomas.

摘要:

The differences were studied between retrospectively calculated emmetropizing intraocular lenses and lenses estimated from different methods and formulas, either with or without the use of ultrasonic biometry. A number of 201 eyes was involved. The results show that ultrasonic biometry is an indispensable tool for the prediction of the power of intraocular lenses, which would produce emmetropia. The best results were obtained when using biometry and the simple empirical SRK formula.

摘要:

The PAP-(peroxidase-antiperoxidase)-immunohistochemical method was tested for rapid diagnosis on corneal specimens in clinically suspected herpetic disease. The method proved accurate, easy and useful in rapid diagnosis of corneal specimens from epithelial keratitis. Corneal buttons after keratoplasties for herpetic lesions were similarly tested for the presence of herpetic antigen. In a total of five corneal buttons, antigen was found in two corneas with necrotizing keratitis, whereas it was not noted in the three corneas opacified by disciform edema.

摘要:

By skin testing, 21 patients with uveitis were more reactive to Candida extracts than a control group of patients during the same 15-year follow-up period. Skin testing with candidin induced an obvious and transient change of the course of the ocular disease in 19 patients and led to systemic symptoms in 15 patients; 11 were atopic, 17 had intermediate uveitis. Antifungal treatment and/or desensitization improved the ocular condition in 16 patients. The real pathogeny of these uveitides remains hypothetical.

摘要:

The ultrastructural study of a case of snail track degeneration shows the presence of lipid inclusions in both the glial and the macrophage cells in every layer of the retina, and the existence of intraretinal fibers different from collagen fibers appearing to be glial filaments similar to those found in astrocytic gliomes and to the Rosenthal fibers observed in senile nervous cells. Other features were thinning of the retina and absence of blood vessels in the retina. There are no abnormalities of the vitreo-retinal juncture. All the lesions are in agreement with those observed by Daicker [Ophthalmologica, Basel 165: 360–365, 1972; Klin. Mbl. Augenheilk. 172: 581–583, 1978] with some differences, however. They are different from those found in lattice degeneration, they show that snail track degeneration is a specific from of peripheral retinal degeneration which is quite different from lattice degeneration and must not be considered similar.

摘要:

A 22-year-old female was admitted to our department due to sudden loss of vision of her right eye. The funduscopic examination revealed a clinical picture of venous stasis retinopathy combined with macular branch artery occlusion. The physical examination and the laboratory tests confirmed the diagnosis of systemic lupus erythematosus.

摘要:

Complete and permanent amaurosis following blood loss is exceptional and occurs in elderly persons with previous circulatory disturbances. We present a case of unilateral amaurosis in an 18-year-old boy following gastric hemorrhage. To the best of our knowledge this is the first documented case of permanent amaurosis following blood loss in a young person.

摘要:

Potassium iodide (KI) passes the cornea of isolated rabbit eyes with kinetics of approximately 0.25 μmol/h/ml aqueous humor. In photodynamic reactions, simulated as light-dependent decay of S-methyl-α-ketobutyric acid in the presence of riboflavin, KI acts as an antioxidant cooperating with internal scavengers such as ascorbate. With the simple model reactions applied it may be possible to study mechanism and functions in vivo of eye-protecting factors or combinations of compounds.
