The paper presents a new test method for investigations of threshold curves for the resolving power of the eye and for exact measurements of visual acuity. This method measures static visual acuity within confidence limits of 9% compared to the acuity steps in Snellen notation of 33% to 50%. Furthermore, the method introduces the slope of the threshold… (More)
It is well known that radiation from welding arcs can cause keratoconjunctivitis and 'glassblower's cataract'. In literature only few cases of welding arc maculopathy have been reported. Three cases are presented.
In 116 diabetic eyes scheduled for vitreous surgery, the visual evoked potential (VEP) after flash stimulation was recorded prior to surgery. Latencies of the flash evoked potentials show a distribution suggestive of a Gaussian curve with an abnormal extension. Dividing the material into two groups based on a latency shorter or longer than 100 milliseconds… (More)
To determine whether or not the electrophysiological status of the eye can give information as to the result of vitreous surgery, the visual evoked potential to flash stimulation was measured prior to vitreous surgery. Seventy-four eyes were submitted to surgery. Latencies of flash evoked potentials showed a distribution suggestive of a Gaussian curve with… (More)
A case of primary acquired melanosis of the conjunctiva is reported. During the 18 years of observation the patient developed a malignant melanoma in the iris, and seven years later a malignant melanoma appeared in the lower lid. The iris melanoma may be an extension from the precancerous melanosis, but the most likely explanation is that the condition… (More)
A translocation of a part of the long arm of a chromosome No. 1 onto the long arm of a chromosome No. 6 was observed in a 2 1/2-year-old boy with mental retardation, harelip, cleft palate and congenital glaucoma. Different banding methods revealed that the translocation t(1;6)(q23;q27) apparently was balanced. The conncection between the patients' symptoms… (More)
Based on a period of introduction with the vitrectomy technic the visual acuity results in 143 consecutive cases performed between 1976 and 1980 are related to the anamnestic information, the pre-, per- and post-operative findings. In this introductional period the patients referred had longstanding retinovitreal changes, and, because of lack of prognostic… (More)
The effect of different dosages of ganciclovir on proved cytomegalovirus chorioretinitis was tested in a randomized trial on 11 homosexual men with AIDS. The effect of 5 mg/kg/day was as good as 10 mg/kg/day. The lower dosage had less toxicity.
