Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. [1] The vitreous humor is the clear gel ...
The extent and location of the intraocular hemorrhage determine the degree of vision impairment. Because of clots or debris in the vitreous cavity, patients may suffer floaters, which are spots or threads in their field of vision. In extreme situations, extensive vitreous bleeding may result in a total loss of the red reflex.
Vitreous hemorrhage. It is one of the most common causes of acute or subacute decrease in vision. [15] Hyphema Blood in the anterior chamber of the eye is known as ...
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.
Cerebroretinal microangiopathy with calcifications and cysts (CRMCC) is a rare genetic disorder, which affects multiple organs. [1] [2] Its hallmarks are widespread progressive calcifications, cysts and abnormalities of the white matter of the brain, usually occurring together with abnormalities of the blood vessels of the retina.
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 ...
Findings include delayed venous filling, hypofluorescence caused by hemorrhage and capillary nonperfusion, dilation and tortuosity of veins, leakage due to neovascularization and macular edema. Optical coherence tomography is an adjunctive test in branch retinal vein occlusion. Macular edema is commonly seen on optical coherence tomography exams.
They are also prone to hemorrhage due to their poor strength. This makes proliferative types of retinopathy more risky since vessel hemorrhaging often leads to vision loss and blindness. [ 14 ] Many of the causes mentioned in non-proliferative retinopathy may also cause proliferative retinopathy at later stages.
