摘要:

A series of 222 cases of 7 mm penetrating corneal grafts were analysed with respect to the influence of HLA compatibility. The degree of compatibility was random as no matching was done (HLA types unknown at time of operation). Consequently, most of the cases showed 3 or 4 incompatibilities.The series was divided into seven diagnostic groups (keratoconus, herpetic keratitis, non‐herpetic keratitis, stromal dystrophy, endothelial dystrophy, mechanical lesion and corrosion). In all groups there was a tendency towards better results among the compatible transplantation, but only when considering the entire series could statistical significance be demonstrated. The groups of 0–2 incompatibilities showed fewer rejection episodes or opaque grafts than the groups of 3 or 4 incompatibilities (x2= 9.20,P<0.005). Comparing only the frequency of opaque grafts among the two groups the correlation was less significant (x2= 3.66,P˜0

摘要:

Fresh and undamaged cornea had unchanged endothelial cell density for four weeks in culture, while eyes removed at autopsy suffered a cell loss. Acceptable cell density was found in eyes removed within eight hours, and this was confirmed by the results of 55 penetrating grafts using cultured autopsy material. Storage in culture for more than one week seemed to influence the results unfavourably. Immune reactions were not seen.

摘要:

One hundred and seven outbreaks of dendritic keratitis have been registered by the ophthalmologists over a 2‐year‐period in a region with a population of approximately 446 000 persons. The incidence was found to be 12/100 000/ year.The average age of our sample was 46.5 years with the same age distribution for males and females, and with a non‐significant predominance of males. No seasonal variation of dendritic keratitis was observed. 50% of the patients had previously suffered from dendritic keratitis. In 25% of the patients the onset of the disease had been preceded by an infectious disease, while 6% were on local steroid therapy for non‐dendritic eye diseases prior to the dendritic o

摘要:

The results of blood‐lipid screening of 200 39–49‐year‐old participants with incidentally diagnosed corneal arcus from the Copenhagen City Heart Study are reported.A large sample of study‐participants of the same age‐group without arcus served as controls.In general, the arcus‐group had higher se.‐cholesterol than the control‐group (P<0.01 in males and<0.02 in females). The se.‐triglycerides in the two groups did not differ.A trend towards positive correlation between arcus‐intensity and cholesterollevel was demonstrated by non‐parametrical statistics. By use of the same statistics, an association between lipids and arcus‐localisation was searched out. Dense arcus in the nasal/lower limbal regions occurred together with hypercholesterolemia more often than did a marked upper/outer arcus.Consequently, based on the present investigation, se.‐cholesterol‐screening of middle‐aged persons with marked lower/nasal arcus seems justified, since hypercholesterolemia might will be an underlying cause.Finally, the importance of diagnosing and treating hyperchole

摘要:

Reflecting colours from the fatty layer of the precorneal film have been studied using mat filter (grease‐proof paper, parchment paper, tracing paper) in front of the slit lamp mirror, maximally open light slit in a half‐lit room, and magnification × 15. The palpebral fissure was narrowed until occurrence of red interference colour (2000 Å).In 206 normal eyes the fatty layer was 102 ± 3 nm (±SEM), or about 0.1 μm, independent of age, sex and BUT (break up time). Maximum on awakening. Coefficient of variation 12.7 per cent.An increased fatty layer was noticed in cases of blepharitis (129±8 nm), in 91 per cent wearing hard contact lenses and 73 per cent wearing soft contact lenses.The fatty layer was likewise seen to be augmented in patients with acute infectious conjunctivitis (193±3 nm), chronic infectious conjunctivitis (164±7 nm), and in all states complicated by bacterial infection.The fatty layer is normal in allergic and chronic simple conjunctivitis. Silicone oil was found to effect reduction of the

摘要:

To study the vascular changes in inflammatory diseases of the cornea 22 patients with various corneal inflammations were examined by means of anterior segment fluorescein angiography. Simple avascular central and marginal corneal ulcers stained with fluorescein in the late phase of angiography. An inflamed limbus and an early microscopic pannus adjacent to the ulcer were seen in simple corneal ulcers. Progressive pannus with pronounced fluorescein leakage was observed in chronic corneal ulcer, disciform keratitis, Mooren's ulcer, and complicated acute keratoconus. In sclerokeratouveitis and in gutter associated with rheumatoid arthritis the corneal vessels showed less leakage. The iris vessels showed fluorescein leakage as a sign of irritative iritis during the active stage of simple and chronic corneal ulcers, in disciform keratitits, Mooren's ulcer, and in graft rejection. It is concluded that anterior segment fluorescein angiography gives valuable information of the vascular architecture, flow and leakage in inflammatory diseases of the cornea.

摘要:

162 employees, the majority women, in an electronic industry were examined in a joint study involving several ergonomic aspects. Some results concerning visual skills are here extracted from a more comprehensive report. No natural selection of fitted workers could be demonstrated. The visual function was found to be only one component of a multifactorial system, which determines the psychological and physical well‐being and productivity of industrial workers. The lack of a sufficient number of abnormal persons and comparable working conditions made it difficult to define limiting visual standards for job performance. Ordinary tests for visual acuity, near vision, heterophoria and stereopsis revealed few facts of importance. More intersting results were obtained when spectacles were evaluated as suitable for the job. 43% of the spectacles were considered insufficient. The use of bifocals did not seem to be related to the need of head movements, and 68% of all the spectacles had tinted glasses, in spite of the fact that the majority of persons wearing them considered the working illumination inadequate.An analysis of the working posture and the visual capacity of the worker should precede the prescription of spectacles for industrial worker

摘要:

A retrospective investigation was carried out of 100 patients below the age of 60 years operated for presenile cataract.The material has been divided into three occupational groups, depending on the visual requirements.The complaints prior to and after operation have been related to the patient ability to retain their employment. Of 78 patients who were still employed, only 45 were able to return to their former occupation after the first cataract extraction.The final result was that 62 patients could continue their former work, 12 changed their occupation due to aphakia problems, while four had to retire. The vision in the fellow eye, the type of work and the optical appliances have been found to be of primary importance.It is concluded that operation for unilateral cataract is inadvisable, if the vision of the fellow eye is good and contact lenses cannot be used, that the time between operations for bilateral cataract should be as short as possible, and that the use of contact lenses is essential.
