Ocular stasis can be caused by many ophthalmic and systemic diseases, as well as by eyelid trauma. Retinal haemorrhage is caused by spasm of the small arteries in the fundus at the beginning of the eye due to hypertension and later hardening; retinal haemorrhage due to diabetes is caused by fragile neovascularisation, and eye diseases such as conjunctivitis and sclerositis can also cause haemorrhage, and ophthalmology is recommended.
