Visual disturbance in pregnancy after induction of ovulation.

The case reported here was not unusual in being first investigated three years before treatment for infertility was instituted. Many patients who attend initially with secondary amenorrhoea only later request treatment for infertility. It is suggested that if a diagnosis of hypothalamic dysfunction has been made originally repeat x-ray films of the pituitary fossa should be taken before gonadotrophic ovarian stimulation is undertaken. Even if there is no evidence of pituitary fossa enlargement at this stage, headache or any other symptom suggestive of an expanding intracranial lesion during pregnancy merits urgent investigation in these patients. We wish to thank Dr. D. A. D. Montgomery and Dr. J. M. G. Harley for their advice in the preparation of this case report, and Professor J. H. M. Pinkerton for referring the patient and for his criticism of the paper.
