Use of placental extract for the treatment of myopic and senile chorio-retinal dystrophies.

After an examination of the literature, the authors evaluate the activity of placenta extract in 34 subjects suffering from chorio-retinal dystrophy of different types (myopic and senile) and of different degrees of anatomo-functional alteration. The parameters used for this study were visual acuity, the luminous sense, the visual field and the electrophysiological activity of the retina. The aqueous solution was administered by intramuscular route at a daily dose of 3 ml (equivalent to 1,80 g of fresh organ) during 20 days; the parameters were tested before and at the end of the treatment. The results obtained during this study show that the parameters were improved, in different degrees, by the administration of the placenta extract. This is clearly demonstrated by the significant improvement in the luminous sense.
