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 ...
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.
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 ...
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
Vitreous hemorrhage – bleeding in the eye from injuries, retinal tears, subarachnoid hemorrhages (as Terson syndrome), or blocked blood vessels. Once blood is removed, photocoagulation with a laser can shrink unhealthy blood vessels or seal retinal holes.
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.
The vitreous body at birth is homogenous with a finely striated pattern. With early aging the vitreous develops narrow transvitreal "channels". The cortex is denser than the centre with development. From adolescence, vitreous tracts form from anterior to posterior. These vitreous tracts are fine sheet-like condensations of vitreous. Named tracts
