  • Title: [Variations of intraocular pressure during valsalva's maneuver in relation to body position and length of the bulbus in myopia (author's transl)].
    Author: Oggel K, Sommer G, Neuhann T, Hinz J.
    Journal: Graefes Arch Clin Exp Ophthalmol; 1982; 218(1):51-4. PubMed ID: 7056482.
    Abstract:
    Intraocular pressure was measured in 49 persons of either sex while carrying out Valsalva's maneuver in erect and recumbent position. 16 of the tested persons had myopia up to -8.0 D. The average intraocular pressure in recumbent position was 2 mm Hg higher when compared to the erect position. During Valsalva's maneuver the intraocular pressure was elevated in erect as well as in recumbent position. Three characteristic patterns of variation of intraocular pressure were seen after cessation of Valsalva's maneuver. The intraocular pressure in myopic persons was slightly higher than in those with emmetropia.
