Of course, mass radiography has widened its scope since its introduction in the early 1940s. It has become a service, a tool for presymptomatic diagnosis. X-ray departments in hospitals are neither meant nor equipped to do this. To destroy such a service without even taking regional differences and problems into consideration is a retrograde step.-I am, etc.,
PRK for low degrees of myopia seemed safe and effective up to 19 years after surgery with conventional broad beam laser ablation. Refractive predictability was significantly lower and the occurrence of haze was higher in eyes with high myopia.
To evaluate the usefulness of the retinal nerve fiber layer (RNFL) appearance in estimation of optic nerve damage in MS, we examined 20 patients with definite MS and 20 normal control patients. Photographs of the RNFL in 80 eyes were classified as normal or abnormal by two examiners working independently. The results were very similar, even though the clinical data of which they were informed and their experience with RNFL-evaluation differed. We found RNFL defects in 80% of MS patients and in 73% of MS eyes. In the control group the values were 5% and 2.5%. Subclinical optic neuropathy in eyes without any history of optic neuritis was demonstrated by RNFL defects in 68%. We conclude, that in detecting clinical and subclinical optic neuropathy, RNFL-evaluation is to be recommended as the method of choice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
