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 ...
Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye (oculus in Latin).Bleeding can occur from any structure of the eye where there is vasculature or blood flow, including the anterior chamber, vitreous cavity, retina, choroid, suprachoroidal space, or optic disc.
More severe complications after a vitrectomy are endophthalmitis (inflammation of the fluids in the eye) or suprachoroidal hemorrhage (bleeding above the choroidal layer of the eye). Rates of these complications have been reported to be less than 0.5%. Lastly, although vitrectomy surgery is often done to correct retinal detachments, a ...
In general, branch retinal vein occlusion has a good prognosis: after 1 year 50–60% of eyes have been reported to have a final visual acuity of 20/40 or better even without any treatment. With time the dramatic picture of an acute branch retinal vein occlusion becomes more subtle, hemorrhages fade so that the retina can look almost normal.
According to Sohan Hayreh, the rupture of capillaries in the optic nerve, which is most likely brought on by elevated retinal venous pressure from central retinal vein compression, is the source of these retinal hemorrhages. The intricate vascular connections between the brain and the eye are highlighted by the fact that Terson syndrome is most ...
Vitreous hemorrhage is diagnosed by identifying symptoms, examining the eye, and performing tests to identify the cause. Some common tests include: Examination of the eye with a microscope; Pupil dilation and examination; An ultrasound examination may be used if the doctor does not have a clear view of the back of the eye
Laser photocoagulation can help prevent the deterioration of some retinal disorders and reduce the risk of future vision loss, but it cannot restore vision once it has been lost. The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes.
Predisposing factors for Postoperative PVR are preoperative PVR, aphakia, high levels of vitreous proteins, [5] duration of retinal detachment before corrective surgery, the size of the retinal hole or tear, intra-ocular inflammation, vitreous hemorrhage, and trauma to the eye. An equation to calculate the patient's risk for acquiring PVR is:
