摘要:

A description is given of a test for determining the ouflow of the aqueous humour. The test consists of compressing the eyeball with a metal funnel attached near the limbus of the cornea by suction. The intraocular pressure increased in this way is kept constant during the test by increasing the suction. The inraocular pressure value is continuously conrolled by an applanation tonometer. The results are based on the amount of extra suction that is necessary to keep the inraocular pressure consant.

摘要:

Keratectomy followed by conjunctival keratoplasty is described in several modifications of the method used originally by Gundersen.Of 60 patients, 44 were seen at follow‐up. The great majority were satisfied with the operation which is distinguished, in particular, by promptly relieving pai

摘要:

Very little is known about the most early stages of retinal angiomatosis. In two patients with advanced angiomatosis in one eye, incipient lesions were found in the other eye. The morphologic characteristics and the findings in fluorescein angiography are described.

摘要:

Vital staining of cornea and conjunctiva with a mixture of tetrazolium and alcian blue effected a permanent green colouring of connective tissue or precipitation of red crystals in 0.6 %>of 1,828 eyes. This colouring subsided in the course of weeks or months.Tattooing can be avoided by omitting vital staining with tetrazolium‐alcian blue in eyes with connective tissue left uncovered by epithelium (from corrosion or deep keratitis, or resulting immediately after removal of sutures or during operation

摘要:

The aqueous humor production is suppressed during the perilimbal pressure cup technique. This effect can be diminished if the intraocular pressure prior to the test is decreased by tonography or bulbar‐pressure test. When such combined procedure was employed the suction cup technique showed a 1.5‐fold increase of the values of aqueous inflow in 91 normal eyes and a 1.3‐fold increase in 25 glaucomatous eyes. In another series of 243 normal eyes, 113 eyes with open angle glaucoma and 91 eyes with chronic closed angle glaucoma, either suction cup test or combined technique was performed. The mean values of aqueous inflow were significantly greater if tonography or bulbar‐pressure technique was performed prior to the suction c

摘要:

A family, with three members affected by a central retinal angiopathy, is reported. The fundus changes consisted of tortuous arterioles, ectatic capillaries, microaneurysms, small retinal haemorrhages and tiny white dots. The changes were demonstrated by colour fluorescein angiography. The retinal changes simulate those described in hereditary haemorrhagic teleangiectasia (Rendu‐Osler‐Weber's disease) and in familial retinal arteriolar tortuosity, both showing dominant inheritance.Although none of the three patients had other stigmata of hereditary haemorrhagic teleangiectasia, it is proposed to consider the presently reported cases, as well as those reported under the diagnosis of familial arteriolar tortuosity, as a localized manifestation of a disorder which in other families may give the clinical picture of Rendu‐Osler‐Weber's

摘要:

Conjunctival lymphocytosis was followed after penetrating corneal transplantations. Examinations were made of scrapings taken with the spatula and stained according to May‐Griinwald‐Giemsa. In a series of 22 ABO compatible transplantations a semi‐quantitative correlation was found between the HL‐A compatibility and the degree of lymphocytosis in the second to fifth postoperative month. It is suggested that conjunctival lymphocytosis reflects immune processes in the cornea. Clinical use of the method could probably be made in the second or third month when strong lymphocytosis would contraindicate a reduction or indicate an initiation of immunosuppressive

摘要:

A method for determination of the venous pressure in the conjunctival and episcleral vessels is described. The external pressure needed for the vessels to collapse is achieved by means of a stream of air directed against the vessel. As the eye is untouched by the instrument, local anaesthetics usually are not needed. The method is fast and easy to perform. The measurements indicate that the pressure of the aqueous‐conveying episcleral veins often is 3–4 mmHg higher than that of the conjunctival ve

摘要:

The four factors, applanating force, applanated area, intraocular pressure and displaced intraocular volume were measured simultaneously and independently in enucleated human eyes. The experiments were carried out at constant intraocular pressure.The relationship between applanating force, intraocular pressure and applanated area was in good agreement with a straight line, but the applanated area was smaller than expected on the basis of the Imbert‐Fick law. The displaced intraocular volumes were larger than would be expected from the corneal applanation alone calculated as spherical segments and indicated additional deformation of the eyeball. The displaced intraocular volume can also be estimated directly from applanating force and intraocular pressure without including applanated area

摘要:

Eine klinische Untersuchung von 126 Augen mit sogenanntem Exfoliations‐syndrom ergab in 90 %>das Vorhandensein einer zentralen Scheibe als Teilaspekt dieser Erkrankung. Bisher konnte die klinisch oft sehr deutliche Veranderung histologisch entweder nicht dargestellt werden oder es wurden Strukturen beschrieben, die dem Spaltlampenbild nur unvollkommen entsprachen. Raster‐ und transmissionselektronenmikroskopische Unter‐suchungen an 4 Kataraktlinsen mit Kapselabschilferung sicherten nunmehr die Existenz einer zentralen Lamelle von charakteristischem Aufbau als morphologisches Substrat fur die klinisch schon lange bekannte zentrale Sc
