  • Title: [Laser scotometry in macular diseases].
    Author: Makabe R.
    Journal: Klin Monbl Augenheilkd; 1986 Feb; 188(2):135-7. PubMed ID: 3713082.
    Abstract:
    Retinal sensitivity is examined by projecting the aiming beam of an argon krypton laser photocoagulator onto the fundus through a contact lens. Even at normal intensity the brightness of the projected aiming on the retina is much greater than the maximum-intensity light target in ordinary scotometry. The discrepancy between scotomata when comparing the results of ordinary and laser scotometry suggests a potential for recovery of visual function, especially in macular diseases. This examination is practicable even if there is slight opacity of the media. By setting the laser beam at sufficiently low intensity, relative scotomata can be detected.
