[Prevalence of refractive errors in 7 and 8 year-old children in the province of Western Pomerania].

Purpose: To determine the prevalence of refractive errors in 7 and 8 year-old schoolchildren in the province of Western Pomerania.

Material And Methods: 140 pupils of elementary schools were examined. Measurements of visual acuity and retinoscopy after cycloplegia were carried out.

Role of light emitted by incandescent or fluorescent lamps in the development of myopia and astigmatism.

Background: The purpose of our study was to determine if the development of refractive errors night be associated with exposure to light emitted by incandescent or fluorescent lamps.

Material/methods: 3377 students from elementary schools, junior high schools and high schools were examined, aged 6-19 years. Visual acuity was measured, and retinoscopy was performed after cycloplegia.

[Transcapillary filtration of plasma proteins in patients with diabetes type II microangiopathy complications].

Unlabelled: This study presents the results of the research on transcapillary filtration of plasma proteins in patients with non-insulin dependent diabetes mellitus (NIDDM). The aims of the study were as follows: (a) Examination of transcapillary filtration of plasma proteins in patients with NIDDM; (b) Search for correlations between metabolic status of diabetes, severity of diabetic microangiopathy and penetration of individual protein fractions into the blister fluid; (c) Examination of the influence of nonenzymatic glycation on albumin fragmentation and its transcapillary filtration. It was also decided to check whether changes in the blister fluid would appear earlier than fundal fluorescein angiography or microalbuminuria, two markers of diabetic microangiopathy.
