Recurring 'red eyes' due to seasonal hypercalcaemia.

Recurrent hypercalcaemia associated with hypersensitivity to ultra violet light occurring in a patient who had had clinical sarcoidosis 14 years previously. Hypercalcaemia in sarcoidosis is a well known association, but it is less often realized that this hypercalcaemia may undergo seasonal variation (Taylor, Lynch and Wyser, 1963). The following case report describes recurring seasonal symptoms associated with hypercalcaemia which persisted for many years after the original diagnosis of sarcoidosis.
