Retrolental fibroplasia--res ipsa non loquitur.

The misconception that retrolental fibroplasia (RLF) occurs only in premature infants who have been exposed to excessive concentrations of oxygen is discussed. The fact that RLF occurs without exposure to oxygen is documented. Basic principles of jurisprudence regarding medical malpractice relating to RLF are discussed. Since RLF can occur without exposure to oxygen the doctrine of res ipsa loquitur should not apply. The burden of proof should still rest with the plaintiff.
