Hyphaema developed spontaneously in 16 of 458 patients with microbial keratitis treated at two centres on the East and West Coasts of the United States. Chronic corneal conditions were often present, and three cases had rubeosis iridis. Inflamed iris vessels were assumed to be the source of the haemorrhage. The hyphaemas tended to persist longer than is usual, particularly when coincident with a hypopyon. Recurrent hyphaemas are reported in two patients from outside this series. Spontaneous corneal haemorrhage was seen in three cases. Subepithelial bleeding settled rapidly, but a combined midstromal and pre-Descemet's haematoma cleared more slowly. Anterior segment bleeding was significantly associated with advanced age, female sex, infection with Gram-positive organisms, and hypopyon.
在美国东西海岸两个中心接受治疗的458例微生物性角膜炎患者中，有16例自发出现前房积血。患者常伴有慢性角膜疾病，3例有虹膜红变。炎症性虹膜血管被认为是出血来源。前房积血往往比通常情况持续时间更长，尤其是伴有前房积脓时。本系列之外有2例患者出现复发性前房积血。有3例出现自发性角膜出血。上皮下出血迅速吸收，但基质中层和后弹力层前血肿吸收较慢。前节出血与高龄、女性、革兰氏阳性菌感染及前房积脓显著相关。
