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.
A tear in the retina can allow fluids from the eye to leak in behind the retina, which causes retinal detachment. When this occurs, blood from the retinal blood vessels can bleed into the vitreous. [4] Retinal tear accounts for 11.4–44% of vitreous hemorrhage cases. [1]
In the dry (nonexudative) form, drusen accumulate between the retina and the choroid, causing atrophy and scarring to the retina. In the wet (exudative) form, which is more severe, blood vessels grow up from the choroid (neovascularization) behind the retina which can leak exudate and fluid and also cause hemorrhaging.

This may cause a neurological bleed to go unnoticed, postponing the proper diagnosis. Retinal vein occlusion: Especially in older people or those with cardiovascular risk factors, retinal vein occlusion, which is a blockage in the retina's veins, causes retinal hemorrhage and visual loss that resembles the symptoms of Terson's syndrome.
The retina specialist’s tests did not reveal any problems with my retina, and the doctor sent me to see a neuro-ophthalmologist to examine the nerves of my eye.
When the retina detaches, common symptoms include seeing floaters, flashing lights, a dark shadow in vision, and sudden blurry vision. [1] [3] The most common type of retinal detachment is rhegmatogenous, which occurs when a tear or hole in the retina lets fluid from the center of the eye get behind it, causing the retina to pull away. [6]
