===Disorders of Haemostasis===
Patients with defective primary haemostasis typically present with pinpoint (petechial) haemorrhages affecting the skin and mucous membrane bevause plateles fail to deal even tiny capillary defects. Petechiae often merge into small, flat bruises called ecchymoses. Ocular haemorrhage (conjunctival, scleral, iridial and retinal petechiae, and hyphaema) is common. Intact secondary haemostasis often prevents major haemorrhage. Disorders of primary haemostasis typically prevents with multiple minor bleeds and prolonged bleeding.
