摘要:

15 patients with glaucomatous field defects in at least one eye were subjected to computerized perimetry and IOP, systemic blood pressure and pulse rate measurements before and after timolol or placebo instillation in both eyes. A significant decrease of IOP and pulse rate was found 2 h after timolol. The visual fields were not improved, the correlation between IOP and visual field performance being (though not significantly) positive. The lack of improvement could not be attributed to the decrease in pulse rate.

摘要:

A comparative study comprising 30 patients with glaucoma and 11 ocular hypertensives showed that pilocarpine 2%–4% and metoprolol 3% lowered the intraocular pressure to the same extent over a 4‐week period. The magnitude of effect corresponded to 29.0% of the untreated pressure level in the pilocarpine group and to 31.9% in the metoprolol group. No statistically significant difference in the pressure lowering effect was found between glaucoma and ocular hypertension. Sufficient control of the intraocular pressure could not be achieved in approximately 35% of the patients with metoprolol single therapy and a tendency towards fading efficiency of metoprolol was noted, but no significant tachyphylaxis appeared during a 5‐month follow‐up period. Local irritation was the predominant side‐effect of metoprolol treatment. Objective adverse reactions recorded were transient, epithelial keratopathy (3 patients) and exanthema (1 patient). Deterioration of a pre‐existing visual field defect was observed

摘要:

In a region where both simple and capsular glaucoma are common, the observed prevalence of glaucoma with glaucomatous visual field defects based on hospital records is presented. The prevalence increased with increasing age to a maximum of 4.5% of the age group 81–85. Capsular glaucomas accounted for two thirds of the glaucomatous visual field defects. A comparison with previous population surveys indicates that the frequency of simple glaucoma is of the same magnitude as elsewhere. The high frequency of glaucomatous visual field defects can be due to the occurrence of capsular glaucoma. This supports the hypothesis that capsular glaucoma has its own epidemiolog

摘要:

Retinal nerve fibre layer (RNFL) photographs taken with a wide‐angle fundus camera (Canon CF‐60Z) and its built‐in blue interference filter (SE‐40) of 495 nm wavelength were compared with pictures taken with the same camera and a red‐free absorption filter (Wratten No. 58) as well as with photographs taken with a 30° fundus camera and Wratten No. 58 filter. Comparison showed that the best visualisation of the RNFL and its defects was achieved with the 60° picture angle of the Canon camera and SE‐40 filter. With a smaller picture angle (30°) and a filter of longer wavelength quality of reproductio

摘要:

The effect of eserine on the IOP on conscious rabbits has been measured with a pneumatic tonometer. The IOP has been recorded to increase 29.4% which is statistically significant.

摘要:

Experiments with VEP to checkerboard stimulation in 4 subjects with normal stereoscopic vision showed that binocular interaction was the same for fused images and for linear pattern displacement induced by horizontal and vertical prisms, as long as the patterns were projected on the macular areas of both eyes. Also in a stereo‐blind subject the impaired binocular VEP interaction remained unchanged during linear displacement of the patterns. Thus the previously reported differences in binocular VEP interaction between stereo‐normal and stereoblind subjects cannot be explained by binocular stimulation with unfused patterns in the latter group. With patterns displaced to different hemifields in the 2 eyes, no binocular interaction was recorded. Experiments with black‐and‐white gratings of different orientations to the 2 eyes showed that binocular VEP reactions remained the same even with patterns perpendicular to each other. However, the binocular interaction was disrupted when the subject viewed the perpendicular patterns through coloured

摘要:

VECPs to checkerboard pattern reversal (12 Hz reversal) at different contrast levels were measured in normal subjects and in patients suffering from diabetes mellitus, with visual acuities above 0.8. VECP contrast threshold was obtained by extrapolating VECP amplitude vs contrast on a log scale to zero μV. Results were compared with psychophysical thresholds. It was shown that both VECP and psychophysical contrast thresholds were significantly higher in the diabetic patients than in the normal subjects

摘要:

Anterior eye segment features were investigated longitudinally by ultrasound and keratometry in 70 low‐birth‐weight subjects (LBW<2000 g) and 67 full‐term controls, at the ages of 10 and 18 years. Concerning the changes during adolescence, a slight significant deepening of anterior chamber and lens position is found (about 0.1 mm), while lens thickness, corneal curvature radius and corneal astigmatism have remained stable. Differences between BW‐groups indicate a permanent influence of LBW on ocular development, as evident from a presumed early environmental (LBW) arrest of corneal growth, given by a significantly lower value of corneal curvature radius, just as zonular slackness due to a smaller suspension ring may explain a thicker lens. Further a LBW disturbance of correlation between refraction and anterior eye segment parameters is suggested. Besides the documented occasional posterior eye segment damage of LBW (retinopathy of prematurity), the present study indicates a more general restraining influence also on anterior eye segment deve

摘要:

The present report on vitreous and axial length completes an analysis of changes in eye size during adolescence. The sample is divided into 70 with low birth weight (<2000 g) and 67 full‐term controls (FT). 1) Contrary to classical statements regarding early arrest of eye growth, a basic ‘pubertal’ axial growth of about 0.4– 0.5 mm is found in refractively static eyes. Eyes with progressive myopia elongate even more, due mainly to vitreous elongation. 2) The previously reported 10‐year LBW ocular size deficit remains an adult feature, even in seemingly normal eyes. There is a parallel permanent lack of catching‐up also regarding height, head circumference, and some other anthropometric parameters. 3) Two classical rules of thumb are discussed: a) 1 mm axial length change coincides with 3 D refractive change, and b) that of 24 mm as the emmetropic eye length. Although tenacious, bot statements have to be modified – according to biological variation and the weak correlation between most refracti

摘要:

Subretinal neovascularization observed over an elevated, pigmented choroidal lesion is usually considered evidence in favour of the benign nature of that lesion, a nevus. Histologic verification of malignant melanoma with choroidal neovascularization has never appeared in the literature. In this report, we present a case of subretinal neovascularization documented by fundus photography, fluorescein angiography, and histology in an eye containing a malignant choroidal melanoma.
