- We conducted a prospective study of 56 patients aged 70 to 79 years undergoing cataract surgery, in order to determine the impact of surgery on subjective and objective measurements of visual ability. In 46 cases we could obtain all necessary data. Binocular visual acuity, near vision and contrast sensitivity improved due to surgery. Self-assessed ability to perform visually related tasks was examined in form of a questionnaire. The results show that there was no simple relationship between objective measurements and perceived visual ability. An impairment in preoperative visual acuity cannot be related to a specific loss of visual ability. In order to increase the quality of cataract surgery more subtly, subjective aspects of vision must be taken into consideration when operation is decided upon and in the evaluation of the results.

- The concentrations of 25 plasma proteins were measured in 29 patients with chronic renal insufficiency. All the patients had terminal renal failure and were treated with intermittent hemodialysis, but were otherwise in good general condition at the time of investigation. The plasma levels of 8 proteins with Mr<50 kD were significantly elevated compared to normal subjects. In contrast, only 2/17 proteins of greater size were found in increased concentrations. The degree of increase in concentration differed substantially between individual low molecular weight proteins, suggesting a complex metabolism in addition to delayed renal elimination. Acute phase proteins and immunoglobulins were not affected by renal insufficiency per se, although erythrocyte sedimentation rates were generally high. The synthesis of acute phase proteins increased normally during the course of inflammation. We conclude that although the sedimentation rate is of no value, complicating inflammatory processes can be traced by quantitative analysis of acute phase proteins, including C-reactive protein, even in patients with severe chronic renal insufficiency.

Accommodative amplitude and subjective symptoms at near in young school children

- Purpose: To establish the sufficiency of the ocular accommodation and to characterize accommodative problems and related symptoms among otherwise healthy young school children. Subjects and Methods: Children from a junior level school were invited to participate in an examination of the accommodative function which was then compared to expected age levels. The amplitude of accommodation was examined using Donders’ push-up method. A questionnaire containing four different questions linked to four different subjective symptoms (headache, asthenopia, floating text, facility problems) was also used.Results: The results showed lower amplitudes than expected in a large group of children and not equivalent to the expected age values. More than one third of the children reported subjective symptoms at near. The incidence of subjective symptoms emerged at the age of 7.5 years and there was significant relationship between low amplitude and subjective symptoms.Conclusions: Accommodation is not as sufficient in young children as expected. Subjective symptoms emerge at the age of 7.5 years and there is a clear relation between accommodative parameters and these subjective symptoms. Clear standards for diagnosing an accommodative dysfunction need to be further refined Because accommodative dysfunctions may result in subjective symptoms, it is of great importance to identify this dysfunction to prevent unnecessary near vision problems.

- The primary aim of this project was to study the effect of flip lens-training on the accommodative function in a group of children with accommodative dysfunction and subjective symptoms such as asthenopia, headache, blurred vision, and avoidance of near activity. We also wanted to measure the accommodative facility among the children in comparison with a control group. Another aim of the study was whether flip lens-training increased accommodative facility, and to find out if it also had a positive effect on their asthenopia and related problems also in long term. Following the training period the accommodative facility and accommodative function significantly increased and two years after finishing the training period no child had regained any subjective symptoms and the objective findings were almost the same as at the end of facility training period. These results suggest that accommodative facility training is an efficient method built on loss of symptoms among children with accommodative infacility.
