[Automated perimetry in patients with posterior chamber implants].

Automated perimetry was performed on 32 eyes of 31 patients with posterior chamber intraocular lens. Visual field and retinal sensibility were studied a week and three months after surgery for each eye. Decreased retinal sensibility in the foveal area was observed in 75% of the eyes. Such a deficiency was also noted in the nasal visual field from 30 to 45 degrees, and within 60 degrees in the temporal area. Further investigation is mandatory to assess our hypothesis about this phenomenon.

[A passive sampler for nitrogen dioxide].

Passive samplers run without electric power supply, are easy to handle and thus are suitable for exposure measurements in epidemiological studies, to evaluate indoor air quality, to control ambient concentrations etc. Passive sampler values agree with continuous measuring apparatus within 85 to 105% and the lower detection limit is 4 micrograms/m3 for a one week exposure or longer.
