摘要:

Flash and pattern visual evoked potentials (VEPs) were recorded in 16 patients with macular disease and in 3 patients with retinitis pigmentosa. Pathological VEP latencies were seen in 14 of the patients with macular lesions and in one with retinitis pigmentosa. Most eyes with a visual acuity below 0.2 showed delayed pattern responses. However, patients with higher visual acuity also had delayed pattern VEPs. It is concluded that an increase in VEP latency is not a specific sign of optic nerve lesion but may also occur in retinal disease, affecting different parts of the sensory retina.

摘要:

Over a two‐year period (1975–76) 329 patients were operated for rhegmatogenous retinal detachment. 301 patients had unilateral detachment and in 62 of these prophylactic photocoagulation with argon laser in the fellow eye was performed. During the observation time one of these (1.6%) and 7 untreated (2.9%) fellow eyes developed retinal detachment. The indication for prophylactic photocoagulation of fellow eyes and the results are discus

摘要:

The contrast sensitivity function (CSF) of 83 patients with retinal diseases was measured by laser‐generated sinusoidal grating pattern, which enables the direct measurement of the CSF between the retina and the brain. The CSF abnormality in various retinal diseases was not specific to each disease, and the severity may determine the pattern. The abnormal patterns and rough correlation with visual acuity (V.A.) are: (1) attenuation at high frequency ranges (V.A.>0.8), (2) attenuation at intermediate and high frequency ranges (0.4

摘要:

This study is an independent clinical evaluation of the ‘Lotmar Visometer’, an achromatic interferometer that uses moiré fringes with variable pitch making quantitative assessment of macular function possible. Light source is a normal low‐voltage lamp. We evaluated this instrument's ability to predict postoperative visual acuity in 90 consecutive cataract patients. 27% could not see the fringes. Among the rest of the patients the correlation between the instrument's prediction and post‐operative visual acuity was generally poor. When used semiquantitatively or qualitatively, the visometer, however, can provide useful information of the macular function in some

摘要:

A critical review of published ophthalmic histocompatibility antigen association studies found numerous conflicting or ambiguous reports. Methodologic errors that could account for these discrepancies were categorized into 3 groups (1) arbitrary application of statistical methods to determine significance, (2) poor sampling design, and (3) variable disease definition. Multivariate analysis, not previously applied in this area provides a more powerful tool for assessing statistical significance. A computer program using this methodology for large studies is now available.

摘要:

Artificial epithelial corneal barriers of histoacrylic glue have been used since 1968. Experimental and clinical studies have since then indicated that the barrier protects the cornea from repopulation by polymorphonuclear leukocytes from the tears and thereby from tissue‐destroying enzymes. Using light‐, scanning electron‐ and transmission electron‐microscopical techniques, the differences between a successful and an unsuccessful treatment of a corneal ulcer with histoacrylic glue have been investigated. The successful glue barrier is a continuous membrane tightly bound to the corneal stroma and preventing population of the stroma by polymorphonuclear leukocytes from the tea

摘要:

Fourty‐three eyes with active dendritic keratitis, nearly one third of which had failed to respond to other antiviral agents, were treated with acyclovir with or without preceding debridement. The patients were randomly selected. No statistical difference could be demonstrated between the 2 groups in terms of rate of healing or in efficacy of cure. Acyclovir also seemed to be effective in stromal corneal lesions. There were only minor side effect

摘要:

Twenty‐eight patients with dacryocystorhinostomies (DCR) a.m. Iliff were examined. 70% of the DCR in patients with idiopatic stenosis and 33% of the DCR in patients with post‐traumatic stenosis had an open DCR. When the catheter was removed 3 weeks or later after surgery the success rates were 93% and 50%, respectively. It is concluded that DCR a.m. Iliff is a simple and reliable met

摘要:

Based on findings in 21 patients with pterygium and 22 normal controls a theory is proposed that pterygium develops initially in the dominant eye. In 13 patients with unilateral pterygium the disorder in 13 was located in the dominant eye. The visual response to intense sunlight of the 21 control subjects confirmed the clinical observation that the non‐dominant eye is closed and the dominant eye held open in people facing the sun. These results might explain why pterygium usually occurs first in the dominant eye. A genetic pre‐disposition for the disorder is lik

摘要:

The incidence of follicle mites (Demodex) has been studied in 206 non‐selected subjects by means of adhesive tape impressions on skin during daytime of nose and lids and moist storage of the tape. The incidence was seen to rise with increasing age: 4% in young subjects, 30% in the age group of 20 to 80, and 47% in older. The mite was more often present on the skin of the nose (17%) than on that of the upper lid (8%), while the incidence on the lower lid was between these 2 extremes (13%). A total of 126 Demodex mites were detected (123 Demodex folliculorum and 3 Demodex brevis), all full‐grown. Of these, 41% were ghosts. The migration was evenly distributed in all directions within the areas examined. About 0.2% of the mites can be roughly estimated to have migrated at a certain point of time from the follicles of the nose to its s
