摘要:

In 93 phakic eyes – 52 eyes with primary open-angle and 41 eyes with exfoliation glaucoma – with increased intraocular pressure, argon laser trabeculoplasty was performed. Fifty to sixty burns were made over 180° of the lower trabecular meshwork. During the follow-up period, visual acuity, intraocular pressure, medication changes and the need for surgery were studied. In 25 eyes a second laser treatment was performed over 180° of the upper trabecular meshwork. Intraocular pressure control was obtained in 81 % of the eyes with primary open-angle glaucoma and 71% of the eyes with pseudoexfoliation glaucoma. The average reduction of pressure obtained after laser trabeculoplasty was 9.22 mm Hg for the group of eyes with primary open-angle glaucoma and 13.42 mm Hg for the group of eyes with pseudoexfoliation glaucoma (p < 0.001). Reduction in medical treatment was obtained in 27 eyes from the 71 eyes with successful reduction of the intraocular pressure. In 6 eyes with successful results after argon laser trabeculoplasty, cataract extraction was performed. The intraocular pressure remained normal in all eyes after the operation.

摘要:

In a planned, randomized, double blind study ocular perfusion pressures were measured before and after a 3-day regimen of 2% carteolol hydrochloride or 0.5% timolol maleate. A pressure tolerance test was also carried out. The results of this test revealed the critical pressure: it is the artificially increased intraocular pressure at which the visual function (monitored by visually evoked cortical potentials) is reduced to 20% of its initial value. The ocular prefusion pressures are affected by both drugs. They are more clearly reduced by carteolol than by timolol. The critical pressure is affected by both drugs too. After application of carteolol, the critical pressure is clearly lower than after application of timolol. The difference is statistically significant (p < 0.05).

摘要:

A 54-year-old woman with a history of bilateral central retinal vein occlusion, probably due to an inflammatory process, developed a hemispheric retinal vein occlusion with cystoid macular edema in her only seeing eye. Five months later, in the absence of improvement in vision and macular edema, she received on two occasions a 2-weekly course of twice daily 100% hyperbaric oxygen. After each course retinal leakage, as assessed by vitreous fluorophotometry, decreased from abnormal to the normal range while visual acuity improved by two lines. The possible implications are discussed.

摘要:

The records of 297 patients with intraocular foreign body (IOFB) injuries were analyzed in a retrospective study ranging from 1956 to 1985, and the data of the three decades were compared. 62% of the IOFB were located in the vitreous, 13.5% in the posterior sclera. There was no significant difference between Haab’s and Hirschberg’s methods in removing the IOFB. In 6.7% an enucleation followed the primary operation, half of these due to postoperative infection. The number of injuries with IOFB has declined. The postoperative improvement of visual acuity has doubled in the last decade compared to the first. The importance of removing the IOFB is stressed, as an unsuccessful attempt considerably worsens the prognosis. 5 of the 297 cases were female, which emphasizes the causative occupational factor. Hammering was the commonest cause of IOFB (80%). None were wearing protective goggles. The importance of wearing protective goggles should be stressed in health education programs.

摘要:

The investigations included 20 aphakic patients. Relations were established between visual acuity, refraction and the pattern reversal visual-evoked cortical potentials (PRVECP). Close correlations were found between the three values. The optimum correction for obtaining best visual acuity, the skiascopic value, and the correction value for obtaining the largest PRVECP amplitude at minimum peak time differ by an average of 0.5 dptr.

摘要:

The investigation comprised 16 patients with verified myotonic dystrophy. The patients were examined ophthalmologically, by electroretinography (ERG) and pattern visual-evoked potentials (VEPs). The results were compared to those of a normal control group. More than 50% of the patients had changes in their lenses or retinas, and the ERGs and VEPs were frequently abnormal. No statistical relation was found between the clinical and electrophysiological findings, and the pattern of abnormalities seemed to vary at random. The number of abnormal clinical and electrophysiological findings increased slightly with the age of the patients, but no statistically significant relation was found either to the patients’ age or the duration of the disease.

摘要:

A rare case of metastatic carcinoid tumour of the choroid is presented. Techniques used to identify the nature of the neoplasm (immunohistochemical or histochemical stains) and the numerous substances possibly secreted by the neoplastic cells (PAP immunocytochemical technique) are discussed.
