This review summarizes 169 cerebral vascular accidents in women taking oral contraceptives: 94 arterial (including 13 of the authors' cases), 20 venous, 37 neuroophthalmologic (5 of the authors'), and 18 undetermined diagnoses. The arterial accidents involved the carotid in 56, the vertebrobasilar in 27. Few were fatal; most were considered thromboses; none were due to hemorrhage; few could have been due to emboli or dissecting aneurisms. Aggravation or appearance of migraine was noted in 34 and transient focal cerebral ischemia in 28 cases before arterial accident. No definite time span was obvious, but many occurred 1-6 months or over 2 years after starting pills. Venous accidents were usually fatal, often extended thromboses of the superior longitudinal sinus. Clinically there was severe headache (85%), vomiting, fever without rapid pulse, alteration of consciousness, papillary edema, focal cerebral signs. Ophthalmologic accidents included retinal, arterial, and venous occlusion; paralysis of oculomotor nerve; optic neuritis; and pseudo-tumor-cerebri. The authors recommended caution with oral contraceptives in case of cerebral vascular episodes, migraine, visual disturbances, chorea, hyperlipidemia, and hypertension.

The commonest cause of an optic neuropathy in Singapore is ischaemia, and ischaemic optic neuropathy (ION) is one of the commonest causes of permanent loss of vision in elderly patients, especially in those with diabetes mellitus, hypertension and hyperlipidaemia. ION in our practice is almost invariably of the anterior variety and non-arteritic in origin, i.e. NA-AION. Posterior ION comprises less than two percent of our cases. Three patients with different patterns of NA-AION are described, and in the discussion, how the condition can be distinguished clinically from optic neuritis. With respect to posterior ION, the necessity of excluding a compressive cause before this diagnosis can be made is emphasised.
