摘要:

The clinical symptoms and signs in 154 cases of ruptured intracranial aneurysms are reviewed. It is demonstrated that retinal haemorrhage is one of the most important and most common signs (32.4% — confidence limits 25–40).It is suggested that fundal haemorrhages be classified on a descriptive basis, grade I being mild retinal haemorrhage, grade II moderately severe cases of pronounced retinal haemorrhage, and grade III severe cases of preretinal or vitreous haemorrhages.A finding of even small retinal haemorrhages in patients who suddenly lose consciousness, with or without neck rigidity, indicates cerebral angiogra

摘要:

A 66‐year‐old man developed bilateral vitreous haemorrhage in connection with a ruptured left‐sided carotid aneurysm. The less severe haemorrhage in the left vitreous cleared in 4 weeks without sequelae, the profuse right‐sided haemorrhage not until 7 months later. The patient was left with a permanent visual impairment due to macular degenerative changes, possibly due to the breakdown products of haemoglobin (iron). Vitreous haemorrhage in subarachnoid haemorrhage must be more common than has been generally

摘要:

Some results of satisfactory operations for the extraction of intumescent cataract lenses after their dehydration with a 50% solution of glycerol are described. The advantages of this technique, which facilitates expeditious and optimal seizing of the capsule of the lens, are outlined and discussed.

摘要:

In 211 eyes pertaining to 125 autopsy cases, 21 retinal breaks were found in 12 eyes of 11 cases. Retinal tears were associated with vitreous adherence while retinal holes were due partly to intraretinal processes and partly also to vitreous traction. The choroid underneath the retinal tears showed areas of thinning and atrophy in some of the eyes, and was normal in others. Chorioretinal adhesions were detected around oral tears and some of the oral and equatorial holes. These adhesions as well as solid vitreous covering the peripheral holes may have been the reason for these retinal breaks having remained silent up to the death of the individual. The reason why other, in this way not protected breaks had not caused detachment, neither the macroscopic nor the microscopic study could reveal.

摘要:

A report is presented of a 56‐year‐old woman with a history of some months of protrusion of the left eye, slight swelling of the upper lid, and decreasing vision. Preoperative examinations indicated an intracranial destructive process around the left optic foramen, and at operation a small tumor was removed. Histological examination showed a typical eosinophilic granuloma, which is most unusual at that age, occurring almost exclusively in children and adolesce

摘要:

Two methods for removal of the vitreous body are described. The efficacy of the methods is discussed and evaluated by an investigation of ten rabbits with14C labelled mannitol infused intravenously through an ear‐vein catheter.The results show that removal of the vitreous body by means of perscleral puncture is more inaccurate compared to removal by means of enucleation, freezing with liquid nitrogen and dissection. The explanation of the lower applicability of the perscleral puncture method is probably the different distribution of mannitol in the vitreous body after 90 minutes constant plasma concentration. The perscleral puncture is thus only applicable when we are sure that a diffusion balance of the examined compounds is present between the central and the peripheral parts of the vitreous bod

摘要:

Feeding of galactose to albino rats results in the development of subcortical and nuclear cataract. The time for cataract formation was highly correlated with the dose of galactose, the minimum time for development of subcortical cataract being four days and for that of nuclear cataract, 45 days.Nuclear cataract did not develop in any case during the 75 days of observation when galactose was given as 15% of the calories. No effect of simultaneous ethanol feeding could be demonstrated.Galactose was found to reduce ATP level of the lens after one week, whereas ADP and AMP levels were constant.

摘要:

The constricting effect of sphincter, and the dilating effect of dilatator, vary inversely proportionally to the size of the pupil.The forces of dilatator and sphincter, which determine the size of the pupil, may be considered as analogous to the forces determining the caliber of a cylindrical elastic vessel, namely the pressure in the vessel and the tension of its wall. The equation S=d · r is analogous to the law of Laplace T=P · r.The pupil is at rest when the force of dilatator is 2π times the force of sphincter. This relationship is the condition of equilibrium.If from a state of equilibrium the force of one or both muscles is changed, the pupil contracts or dilates until the condition of equilibrium, as stated above, is again establish

摘要:

Three cases of Morning Glory syndrome are described, two of which were unilateral, one bilateral. Ophthalmoscopy revealed an enlarged optic disc, surrounded by a typical elevated zone showing scattered pigmentations. Vascular anomalies were observed in and around the optic disc as well as more peripherally. Both narrow and larger abnormal blood vessels were seen. The narrow pathological vessels were better demonstrated by fluorescein angiography than by ophthalmoscopy. No pathognomonic vascular changes were discovered. In one eye the retinal pigmentation was sparse peripherally, with a distinct demarcation against the more normal pigmentation seen posteriorly. All affected eyes were myopic, which seems to suggest that this error of refraction may be a characteristic of the Morning Glory syndrome. The anomaly does not necessarily cause marked diminution of vision. Ectatic portions of the bulb were discovered ophthalmoscopically. The Morning Glory syndrome appears to be a malformation involving not exclusively the blood vessels and optic disc.

摘要:

The release of fibrinolytic agents from human cornea was studied by culturing foetal corneal explants in the presence of a standard fibrin clot and measuring the fibrin degradation products formed in the culture medium. Cultures of cornea were found to invariably release a significant amount of fibrinolytic agents, probably fibrinolytic activators, since Tranexamic acid, an inhibitor of plasminogen activation into plasmin, completely blocked the dissolution of the clot in the culture system. The function of these fibrinolytic activators is presumably to keep the cornea free from fibrin deposits which may occur after injury or inflammation.
