摘要:

All Swedish cases with the Sjögren‐Larsson syndrome (SLS) i.e. 35 patients were studied. Glistening dots of unknown nature were seen round the foveola. These foveal and parafoveal changes seem to be a cardinal sign of SLS together with congenital ichthyosis, spastic di/tetraplegia and mental deficien

摘要:

Examination of 113 eyes vital‐stained by Sudan powder revealed that fat on the skin of outer canthus may pass onto the precorneal film (in 68%), and that the most reliable staining is obtained by application on the bulbar conjunctiva below the limbus corneae at 6 o'clock.In 41%, the precorneal film had stained drops or foam, with a tendency towards an increase among pathological cases (infectious conjunctivitis and blepharitis). An increased amount of fat was found in the mucous thread of eyes affected with infectious conjunctivitis and lagophthalmos. In a small number of pathological cases fat was also detected on cornea, bulbar conjunctiva, and inferior fornix.The fatty layer on the lower lid margin was stained more frequently and more intensely than that on the superior.The secretion of the meibomian glands was stained in no more than a scant one half of the glands (on an average 44%), independently of age, sex, site, and diagnosi

摘要:

The colour discrimination of 15 subjects manifesting senile macular degeneration was investigated, over a wide range of illuminances, using the Farnsworth‐Munsell 100‐Hue test and Panel D‐15. Ten subjects of similar ages with normal colour vision were investigated concurrently to provide a control group. Colour discrimination was shown to deteriorate with decreasing illuminance this being more marked for the subjects with senile macular degeneration than for the normal subjects. It is demonstrated that the FM 100 is the preferred test for assessment of colour discrimination loss in senile macular degeneration with early visual acuity loss. The Panel D‐15 is more useful as acuity loss becomes more

摘要:

In 63 diabetic children, aged 10–14 years, with normal ophthalmoscopy, fluorescein angiography revealed slight diabetic retinopathy in maximally three, aged 12–14 years. These findings are discussed in relation to the controversial results published in a few other fluorescein angiographic studies on diabetic children.It is concluded that normal ophthalmoscopy does not exclude the presence of diabetic retinopathy and that fluorescein angiography is a valuable method in the early diagnosis of diabetic retinopa

摘要:

The present study is a fluorescein angiographic follow‐up of 60 diabetic children (aged 12–16 years).At the follow‐up, with two‐thirds of the children in pubescence, fluorescein angiography revealed diabetic retinopathy in 10 (17%) of the children.The results indicate puberty as a probable determining factor influencing the onset of the diabetic reti

摘要:

Seventy‐three diabetics with retinopathy, in whom one eye was treated by photocoagulation, and the other was left untreated, were followed‐up for 9 to 11 years. Visual acuity, visual field, dark‐adaptation curves, and intraocular pressure were recorded; biomicroscopy and photography of the fundus were carried out. Severe visual loss (<0.1) was noted in 4% of the treated and in 25% of the untreated eyes. Minor, subjectively unnoticed, scotomas were found at visual‐field examination in 18 of 40 treated eyes. Dark‐adaptation curves showed abnormal values both in the treated and in the untreated eyes, without any recordable difference. No contra‐indicating long‐term complications of the photocoagulation treatment could be

摘要:

In 10 diabetic patients with normal intraocular pressures, the effect of monocular panretinal xenon photocoagulation was recorded with the applanating suction cup tonograph applied bilaterally. One month after the treatment, the photocoagulated eyes showed an average decrease in pressure of approximately 3 mmHg, which was statistically significant (P<0.001) when compared to the untreated fellow eye. On a percentage basis the falls were of a similar magnitude (approximately 25%) as those observed by others after photocoagulation in neovascular glaucoma.

摘要:

An improved applanating suction cup for continuous recording of human intraocular pressure is described. The new cup adheres better, is easier to calibrate, and is simpler to handle, mainly due to a different curvature of the applanating surface. The interspace between the applanating and the applanated surface, in which the pressure is measured, is continuously flushed with saline from a flow system (Intraflo®) connected to the dome of the pressure transducer. The suction that attaches the cup to the cornea is — as in the previous model – provided by a saline filled tube hanging from the cup. In 51 human cadaver eyes the calibration for static pressures and pressures oscillating up to 124 cycles per min was: intraocular pressure = 0.9 × cup pressure –3 (mmHg), r = 0.995. The cup reduced ocular rigidity by 5% only and increased the intraocular pressure transiently by 4 mmHg when applied. Simultaneous bilateral recordings were obtained in 400 normo‐ or hypertensive eyes from 206 subjects. The cup was atraumatic, and the method can be strongly recommended when accurate, bilateral pressure recordings are desired for periods up to one h in supine subjects. At intraocular pressures above 35 mmHg, the tonograph may underestimate the pressure under certain, unfavourable c

摘要:

In the investigation of suspected visual disorders, ERG is of considerable value. A simplified method for clinical electroretinography by non‐corneal electrodes is presented. The latency and amplitude values were measured in 22 normal subjects. Using skin electrodes and signal averaging, we can record, without discomfort to the patient, an electroretinogram with a waveform and time relations similar to those obtained by corneal electrodes. Non‐corneal ERG is useful for infants, children as well as sensitive adult patients, and is also applicable after recent eye surgery and in cases of infection or injury of the anterior segment. Since non‐corneal electrodes do not obstruct the stimulus light or cause refractive change, they are advantageous when ERG is recorded simultaneously with visually evoked cortical response (VER). When it is important to stimulate only one eye at a time in flash VER, the adequacy of the cover is verified by the absence of an ERG from the covere

摘要:

The occurrence of carbonic anhydrase isoenzymes C and B in the retina of the human eye was examined with specific antisera against these enzymes. Immunological analyses were carried out by the double diffusion method of Ouchterlony, and the localization of the enzymes was studied by an application of immunoperoxidase (PAP) technique. A large amount of isoenzyme C was detected in tissue sections from the human retina, whereas the isoenzyme B was totally absent. Isoenzyme C was considered to be located primarily in the glial elements of the retina, correlating with the earlier findings obtained by traditional metal salt methods.
