The standing potential of the eye is decreased by intravenous administration of hypertonic solutions. This hyperosmolarity-induced response has been recorded in normal subjects by the use of electro-oculography (EOG) in the dark. An intravenous administration of Fructmanit (1.4 X 10(3) mOsmol) (150 approximately 500 ml, 2.37 approximately 9.70 ml/kg, 0.08(More)
Effect of sodium fluorescein was examined on neurite outgrowth from the retinal explants of chick embryos cultured with chicken gizzard extract, containing macromolecules which promote neurite outgrowth. A dose more than 0.5 mg/ml of fluorescein completely prevented the neurite outgrowth from the retinal explants. The minimum dose of toxic effect of(More)
The hyperosmolarity response of the standing potential was recorded in retinitis pigmentosa (20 eyes), central (pericentral) retinitis pigmentosa (4 eyes), pigmented paravenous retinochoroidal atrophy (2 eyes), fundus albipunctatus (8 eyes), and Stargardt's disease (or fundus flavimaculatus) (14 eyes). The light peak/dark trough ratio (the L/D ratio) and(More)
The hyperosmolarity response of the ocular standing potential was recorded in unilateral rhegmatogenous retinal detachment (8 eyes) and in the fellow 'healthy' eye (8 eyes). The hyperosmolarity response was greatly suppressed (M-4 SD: M and SD indicate respectively the mean and the standard deviation in normal subjects) in all affected eyes (p less than(More)
