Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...
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. [6]
Hyphema treatment begins with head elevation to about 30 degrees, including while sleeping. An eye shield should also be placed and worn until the hyphema has completely resolved. [9] Vitreous hemorrhages are treated by targeting the underlying cause, such as with laser photo-coagulation for proliferative diabetic retinopathy or retinal detachment.
Depending on the location and extent of the bleeding, valsalva retinopathy usually resolves within weeks to months, without any complications. [4] Patients are instructed to avoid anticoagulant drugs and physical activities which cause increase in intrathoracic or intra-abdominal pressure. [4]
The immediate cause of death is pneumonia, fulminant intestinal bleeding or multiple organ dysfunction. [1] If not treated, the retinal detachment can lead to ischemia and growth of new blood vessels over the iris and anterior chamber angle. This in turn can cause secondary glaucoma, cataract and, ultimately, blindness of the eye. [1] [2]
Acute retinal necrosis (ARN) [1] is a medical inflammatory condition of the eye. [2] The condition presents itself as a necrotizing retinitis . [ 3 ] The inflammation onset is due to certain herpes viruses , varicella zoster virus (VZV), herpes simplex virus (HSV-1 and HSV-2) and Epstein–Barr virus (EBV).
