  • Title: [The absolute light sensitivity of the visual analyzer in sailors during a 10-month commercial voyage].
    Author: Ponomarchuk VS, Voloshin MK.
    Journal: Oftalmol Zh; 1989; (2):107-11. PubMed ID: 2755652.
    Abstract:
    For the purpose of studying the influence of extreme conditions of a long-term voyage on the functional state of the visual analyser, light sensitivity was studied in 21 seamen. It is shown that adaptation mechanisms regulating light sensitivity have a phase tendency: phase is characterized by a rise of the level of light sensitivity within first 90-120 days of the voyage; phase II--by a gradual fall of the level of light sensitivity beginning from 120-140 days of the long-term voyage. The investigations performed allow to create an informative diagnostic test for a well-grounded therapy intended to widen adaptive possibilities of the system responsible for regulation of light sensitivity.
