Recent advances in retrolental fibroplasia

Retrolental fibroplasia is the most common cause of preschool blindness. Changes identical to retrolental fibroplasia in humans have been produced in animals by exposing them to high oxygen concentration. Oxygen should be ordered for premature infants in a careful and precise manner. Concentrations of over 40 per cent should be avoided whenever possible. Withdrawal to air should be a gradual process.
