Radiation-induced cataract in astronauts and cosmonauts.

Background: Opacification of the ocular lens is an important effect of exposure to ionizing radiation. Astronauts and cosmonauts are exposed to relatively high doses of all types of radiation in space, including high-energy particle radiation. A study was initiated to examine the lenses of the eyes of astronauts/cosmonauts to detect signs of radiation-induced cataracts.

Perioperative cataract OP management by means of teleconsultation.

Background: Teleconsultation services have the potential to improve the communication among different medical care providers and between them and the patient. Increasing effectiveness in the shape of a savings in time or cost is often the result of better communication.

Methods: A study was performed in order to demonstrate the feasibility of teleconsultation services, using the perioperative management of cataract patients as an example, and to provide data on the quality, acceptance and effectiveness of these services in comparison with a control group experiencing normal treatment.
