摘要:

The posterior annular compression test aims at estimating the aqueous outflow facility as well as at detecting the predisposition to the closure of the anterior chamber angle. An annular compressor weighing 50 g is placed on the globe in a posterior position to the iris‐lens diaphragm for 3 min. In 115 normal eyes the intra‐ocular pressure dropped after the test by 22 % or even more and the volume of the eyeball decreased not less than 5.5 mm3designing the limits for a negative test. In patients with open‐angle glaucoma the test was positive in 86 % of the 58 eyes examined. However, in all these cases a decrease of the intra‐ocular pressure occurred. The tension and the volume of the globe increased or remained unchanged in 35 eyes of the total of 52 with chronic closed‐angle

摘要:

The ophthalmological findings in 16 children with infantile type of neuronal ceroid lipofuscinosis are presented. All patients showed signs of a progressive encephalopathy with onset at the age of 8–18 months. Visual failure, ataxia, muscular hypotonia, microcephalia and myoclonic jerks were typical findings. Fluorescein angiography showed narrowing of the retinal vessels and pigmentary dystrophy as well as optic atrophy. The site of the primary defect was thought to be the pigment epithelium and receptor cells. The ERG was abolishe

摘要:

The cataractogenic effect of exposure to microwaves has been reported by several authors. Effects on the central nervous system also have been discussed. Whether the effect is thermal in origin or nonthermal is not known. In this paper the authors show that in a factory where radar‐and other microwave equipment was tested, an overrepresentation of lens opacities could be observed in personnel in the lower age groups. Furthermore, it was noted that changes in the retina resembling chorioretinal scars were present in a significant number of worker

摘要:

The eye movements of patients with latent nystagmus were recorded during monocular gaze intention following acoustic stimulation in complete darkness and in a series of experiments with the aid of the katoptric pseudoscope of Ewald. It appears to be the intention of “looking‐with‐one eye” which elicits latent nystagmus. Moreover, it can be shown that the moment of appearance and the direction of the nystagmus are determined not by the illuminated retina but by the act of “pointing” an object with one eye. The preponderance of motor over sensory factors, and especially of intentional motor behaviour, is clearly demonstrated. The possible central mechanism of latent nystagmus i

摘要:

An extensive electronystagmographical examination was made of 25 members of a family with Åland eye disease (Forsius‐Eriksson syndrome). It appears that the nystagmus belongs to the syndrome of latent nystagmus. Out of seven investigated male subjects with Åland eye disease, five showed classical latent nystagmus and two had slight manifestations of latent nystagmus. Of nine investigated female subjects, only two revealed a very slight latent nystagmus. According to our studies we can postulate two modes by which latent nystagmus could have been inherited in this family:1an X‐chromosomal dominant type of transmission with decreased or lack of penetrance in a number of female carriers;2a recessive X‐chromosomal transmission with slight nystagmus as a sign of heterozygosity in the female carriers.The combination of latent nystagmus with the X‐chromosomal Åland eye disease may be explained by pleiotropic g

摘要:

In a double‐blind study, 10% oxyphenbutazone (Tanderil®) eye‐ointment was compared with bibrocathol eye‐ointment in the treatment of superficial foreign bodies in the cornea of 100 patients. Pain and redness were more quickly alleviated with oxyphenbutazone, whereas there was no difference in the effects of the two kinds of treatment on corneal edema and corneal erosion. No ill‐effects or complications we

摘要:

Factors thought to affect the accuracy of Schiötz readings (age, sex, refraction and systemic blood pressure) were studied by means of a multiple regression analysis in a material of paired Schiötz and Goldmann readings derived from a general ophthalmic population survey. Age was found to be the most important source of variation in the relationship between applanation and impression tonometer readings. The change with age was confined to a relatively short period ‐ from the late fifties to the late sixties. The direction, amplitude and timing of the age effect are such that one important sign of early glaucoma ‐ a rapid rise in ocular tension ‐may well pass unnoticed by impression tonometry. We conclude that the advisability of Schiötz tonometry for any kind of “follow up” studies on persons in their sixties shoul

摘要:

The instillation of 0.2 % 9α‐fluoro‐16α‐methylprednisolone twice daily in the left eye of rabbits for 30 days induced significant biochemical changes in the vitreous body. Actually, a marked acidification accompanied by a decrease in the buffer base, a notable increase in osmotic pressure and a reduction in the ascorbic acid content were observed. These changes are compared with those evidenced in the blood and aqueous humor. An interpretation of the data obtained is suggested on the basis also of the close relationship existing between the vitreous and the

摘要:

The colour vision of 12 patients with tobacco amblyopia and 12 normal controls matched for age and sex was tested with the Pickford‐Nicolson anomaloscope and the Farnsworth‐Munsell 100‐Hue test. The results of the two tests were correlated (ϱ = + 0.768,P<0.01) in that the higher the matching range on the P‐N anomaloscope, the greater is the error score on the 100‐Hue test in tobacco amblyopia. The matching range (t = 9.78,P<0.001) and the 100‐Hue test (t = 5.43,P<0.001) score were significantly higher than those of the controls. The acquired colour defect in tobacco amblyopia with the P‐N anomaloscope is of extreme protanomalous type ‐ the mean mid‐matching point being shifted towards the red by more than the 3 × s.d. limits for

摘要:

The colour vision of 10 patients with successfully treated unilateral retinal detachment with macular involvement was tested with the Farnsworth‐Munsell 100‐Hue test. A method has been described for inter‐eye comparison on the 100‐Hue test error scores. In seven affected eyes the error scores were significantly worse at the 0.01 level of significance than those of their contralateral normal eyes. Three of the affected eyes had normal colour vision; two showed a Red‐Green colour defect; three showed a Yellow‐Blue colour defect and two were nonspecific. It is concluded that a retinal lesion can cause a RG colour defect in addition to the generally accepted YB and nonspecific colour defects. The uniocular dyschromatopsia is found to impair significantly (P<0.01) the binocular vision when the patients' affected eye error scores and binocular error scores were compared with the uniocular and binocular error scores of age matched norm
