  • Title: [The recovery of the local ERG recorded from reattached retina after retinal detachment].
    Author: Kamei S.
    Journal: Nippon Ganka Gakkai Zasshi; 1992 Jun; 96(6):776-83. PubMed ID: 1626479.
    Abstract:
    The functional recovery of the reattached retina after retinal detachment was investigated electrophysiologically. Experimental retinal detachment approximately 4 mm in diameter was made in the rabbit eye by injecting Hanks' solution (HS) or sodium hyaluronate (HNa) into the subretinal space. Local ERG (LERG) was recorded from the spontaneously reattached retina by a double-barreled microelectrode. The retinal detachments caused by HA reattached at an average of 321 +/- 56 minutes after making the detachment, while the detachments by HNa at 20.8 +/- 1.8 days. The recovery of the amplitudes of b-wave and slow P III of the LERG was slower and worse in HNa group than in HS group. In both groups, the amplitudes of the b-waves recovered earlier than the slow P IIIs. Result indicated that earlier reattachment is related to favorable recovery of the retinal function, and that the inner retina generating the b-wave restores its function earlier than the distal retina generating the slow P III.
