Corneal blood staining after hyphaema

Abstract

(1) The clinical and pathological features of corneal blood staining are reviewed and the differentiation from corneal haemorrhage is discussed. (2) Six examples of corneal blood staining which occurred in a series of cases of traumatic hyphaema are described. The condition was only observed after the occurrence of a total secondary hyphaema. (3) Some further suggestions regarding the aetiology of corneal blood staining have been made based on clinical features observed in these cases. Although a sustained rise in intraocular pressure is a contributory factor, it does not appear to be mandatory. (4) The prognosis is good in the absence of associated ocular damage; clearing was com-plete in four out of six cases within 3 years. (5) The incidence rises sharply from 2-1 per cent. in the whole series to 33 per cent. If the complication of total secondary hyphaema occurs.
