doctor does not have a clear view of the back of the eye Blood tests to check for specific causes such as diabetes A CT scan to check for injury around the eye Referral to a retinal specialist Complications Ghost cell glaucoma: Secondary open angle glaucoma caused by degenerated red blood cells. Treatments The treatment method used depends on the cause of the hemorrhage. In most cases, the patient is advised to rest with the head elevated 30–45°, and sometimes to put patches over the eyes to limit movement prior to treatment in order to allow the blood to settle. The patient is also advised to avoid taking medications that cause blood thinning (such as aspirin or similar medications). The goal of the treatment is to fix the cause of the hemorrhage as quickly as possible. Retinal tears are closed by laser treatment or cryotherapy, and detached retinas are reattached surgically. Even after treatment, it can take months for the body to clear all of the blood from the vitreous. In cases of vitreous hemorrhage due to detached retina, long-standing vitreous hemorrhage with a duration of more than 2–3 months, or cases associated with rubeosis iridis or glaucoma, a vitrectomy may be necessary to remove the standing blood in the vitreous.
